Effects of Harmonic Distortions on the Accuracy of Energy and Power Losses Measurements in a
Water Treatment Industry
Nayusrizal N, Indira Untari, Andi Aulia Putra and Chairul Hudaya
Universitas Indonesia, Indonesia
Abstract-Harmonic distortions in electric power system are the main power quality concerns, mostly
generated by non-linear loads such as Variable Frequency Drive (VFD). A water treatment industry
S1-0081
usually utilizes VFD to control their water pump motors during the operation. In this study, we
13:00-13:15
investigated the effects of harmonic distortion resulted from VFD on the measurement accuracy in
the distribution system operated by state-owned electric utility. The results showed that the VFD
that employed the pulse width modulation (PWM) technique has adjusted the supply frequency of
50 Hz into specific number to control the speed of motors. Data recorded on energy meter for seven
days exhibited the THDV of 3.27% and THDI of 36.37%. We found that the harmonic distortion has
caused the energy measurement error of 1.2%, and this becomes potential losses for the utility
because it could not be charged to customers due to the government tariff regulation
Analysis of variation in steam turbine time constant on dynamic frequency regulation of a
deregulated power system
Arun V Jose, Sunitha R and Deepak M
National Institute of Technology of Calicut, India
Abstract-At present, increase in renewable penetration has paved the way for the shutdown of
existing thermal power plants. This forced system operator, to operate remaining thermal power
S1-0027 plants mostly around 70 % to 90 % of its generation schedule. In this paper, effect of varying steam
13:15-13:30 turbine time constant on a re-heater based two-area thermal power system under deregulated
environment is analysed. The analysis has been carried out for different scheduled power output of
the plant, such as 100 %, 90 %, 70 % and 50 %. The steam turbine time constants for each
generation schedule is determined and simulations were carried out for three scenarios, such as
unilateral, bilateral and a case of contract violation. In each case, four generation schedule
mentioned earlier is taken into account. A comprehensive study was done by analysing all the
aspects of a deregulated two area reheater based thermal power system, considering various
generation schedules.
Accurate Classification of Disturbances and Cyber-attacks in Power Systems Using Recurrent Neural
Networks
Wei-Chih Hong, Ding-Ray Huang, Shun-Chi Chen
Feng Chia University, Taiwan
S2-0025-A Abstract-Correct and timely responses to abnormal conditions in the power systems are crucial to
13:30-13:45 their sound operation. In order for the operator or the automated response system to take prompt
measures during system contingencies, it is critical to facilitate an accurate mechanism for the
classification of the events and disturbances in the power grid. Massive amount of
time-synchronized data recorded by the synchrophasors can be combined with logs from other
components in the power grid to create datasets for event and intrusion detection. This paper
presents results of applying deep learning techniques on open datasets of power system attacks to
14SESSIONS
classify contingencies. Three different designs of recurrent neural networks (RNN) are investigated
and tested for discriminating binary, and multi-class datasets. Experiments show 100% accuracy and
zero false positive results when the parameters of RNN is correctly chosen and the models are well
trained. The promising results demonstrate the potential of employing RNN techniques in
developing event and intrusion detection systems for power grids.
The Effects of Vacuum and Oil Impregnation Duration on Partial Discharge of 167 MVA 500/150 kV
Single Phase Power Transformer
Agus Indarto, Rudy Setiabudy, Radin Rahmatullah, Iwa Garniwa, Chairul Hudaya
Indonesia University, Indonesia
Abstract-Manufacturing process of oil immersed Power Transformer (PT) has significant effect to the
value of its partial discharge (PD). PD is one of the most important parameters of PT to ensures the
reliability and quality of the PT's operation PT. As PT is one of the most important parts in electrical
power system, PD becomes one of the key performance indicators for PT. The quality of
manufacturing process of both liquid and solid insulations will reflect to the PD value of PT. Both
solid and liquid insulation will form the overall insulation of integration of PT. One of the important
S1-0034
manufacturing processes is vacuum and oil impregnation process. These processes ensure the
13:45-14:00
removal of the moisture from PT insulation and keep maintaining PT from moisture ingress. In this
study, the experiment is conducted to investigate the relation between vacuum and impregnation
process duration to partial discharge value of 167 MVA 500/150 kV on single phase power
transformer. Twelve (12) samples are investigated during manufacturing process and final
acceptance testing by measuring vacuum and impregnation process duration as well as the value of
partial discharge. The result shows that vacuum process duration has significant effect to PD values.
Combined with oil impregnation process of the insulation, the results show that to achieve PD below

The Development of Power Substation Communication Using Independent Network of Synchronous
Digital Hierarchy
Hartono, Ariono Verdianto, Chairul Hudaya
Universitas Indonesia, Indonesia
Abstract-The failure detection of substation equipment causing the system blackout is the main
problem in electrical transmission due to the delayed data transmission network. The
communication among electrical power substation is an essential part of the protection system in
S1-0085 electrical power transmission for providing a reliable network. So far, the Indonesian electric utility
14:15-14:30 entrusted the third parties to provide the communication network. However, this pathway has the
drawback in data transmission, for instance data delayed, because it is not directly integrated with
the system. Thus, in this study, we proposed a novel built-in method that allowed the user to
conduct a real-time monitoring on the entire system. We implemented two stages; the first stage
was to deploy the primary multiplexer to provide 2 Mbps loop network, while the second stage was
to develop the independent network by installing the synchronous digital hierarchy (SDH) network
to replace the existing one. Based on G.703 channel test, we found that the proposed network was
capable of replacing the third parties network, confirmed by direct testing using network monitoring
system.
The Investigation Impact of Variable Installed Capacity Wind Farm on the Power System
Kanthanachuck Vorabout, Chayada Surawanitkun, and Arkom Kaewrawang
Khon Kaen University, Thailand
Abstract-Penetration of wind power generation into the power system has greatly affected the
electrical power system because the increment of installed capacity of wind farms (WFs) causes the
variable power flow in the system. This paper presents assessment of an electrical effects depending
S2-0016 on the installed capacity of WFs. Firstly, a scenario is analysed power system before and after WFs
14:30-14:45 connected into power system of the Central II-part of Lao PDR by DIgSILENT power factory software.
Secondly, the installed capacity WFs is inserted into simulation with the two located. The propose of
this study is comparative the result of electrical effects based on the ratio installed WFs each
location. It has been demonstrated variable power flow and current flow into substations on the
power transmission. In addition, the result shown limited performance of installed WFs power
generation in the system. The outcome of a novel scenario is considering the power system to
determine an electrical effects when the increment installed capacity of power generation also that
is a planning extension of power generation in the Central II-part, Lao PDR.
Using power factor to limit the impact of energy storage on distribution network voltage
D Strickland , S Morley ,D.A Stone, S.J Royston , S Nejad , D.T Gladwin, M.P Foster
University of Sheffield, UK
S2-0009
14:45-15:00 Abstract-The introduction of embedded renewable generation and energy storage into the
electricity grid may result in increased complexity to the Distribution Network Operator (DNO) in
managing the voltage within statutory limits. This paper investigates how the voltage at the point of
common coupling between the grid and an energy storage system could be adapted such that the
16SESSIONS
charging and discharging of a battery energy storage system has a neutral impact on the voltage at
that point. The paper uses measured results from the Willenhall Energy Storage System to show that
a “seagull” shape curve of Power and corresponding Var setting could be used to mitigate against
voltage rise or fall on the Network caused by the Energy Storage System.

Low-cost and Compact Window Comparator Circuit with MOSFET-Resistor Voltage References
Chuthong Summatta, Tharathip Phurahong, Weera Rattanangam and Weerathum Chaiyong
Nakhon Phanom University, Thailand
Abstract-A window comparator circuit is utilised for industrial applications and is related to safety
systems for the detection of false signals that check the DC signal level from input. The design
concept is based on AND logic circuit. Originally, the window comparator comprised two methods
S1-0056 including 1) analogue circuit dependent on the transistor oscillation, which is determined by the
15:15-15:30 values of resistance and each input voltage, and 2) window comparator with op-amp or module ICs
comprised of two separate comparators and an AND gate. This paper proposed a window
comparator with digital logic IC based on the features of digital switching levels with
MOSFET-resistor voltage references. The circuit uses a potential voltage divider circuit utilising
resistor and N-channel MOSFET, as well as the threshold voltage of CMOS logic IC to build window
boundaries. It does not require any additional components since it is a very simple circuit. The circuit
can be used in low voltage and fast varying input. The performance was tested and analysed by
simulation and experimental results.
Practical observations of loss-of-mains nuisance tripping of fast acting energy storage
Simon J Royston, Dani Strickland, David A Stone, Daniel T Gladwin, Martin P Foster, Shahab Nejad
University of Sheffield, UK
S2-0008 Abstract-Fast acting battery energy storage systems are able to swing power very quickly between
15:30-15:45 maximum import and maximum export in less than 50ms based on operational experience of a
2MW energy storage system. However, this can result in nuisance tripping of the unit through the
operation of the loss-of-mains protection (LoM). This paper looks at data captured during power
swings of up to 4MW during typical operation and discusses the potential for nuisance tripping, and
suggests potential settings for improved operation.
Design and Performance analysis of digital control laws for low power high frequency switching
power supply
Shubha Rao K and Veena S Chakravarthi
B N M Institute of Technology, India
Abstract-This paper describes the design and performance analysis of the digital power supply
regulator for System On Chip (SoC). The digital switching mode power supply consists of DC-DC buck
converter providing 1V DC at 10 MHz switching frequency. To obtain a stable output under variable
S1-0028
load and line conditions, three types of architectures for digital control laws i.e. PID controller, Type
15:45-16:00
III compensator and Sliding mode controller are explored. Simulation using Matlab/ Simulink tool
and Hardware-software co-simulation using Xilinx system generator is performed to analyze their
performances. Among these three, Type III compensator is proposed which gives the best
performance under wide load current and input voltage variations in terms of undershoot and
response time. With type III compensator, a settling time in the range of 11-15 μs and maximum
peak overshoot in the range of 2-8% is obtained for load variations and settling time in the range of
13-15μs and maximum peak overshoot in the range % of 2.2-4.5 % is obtained for line variations. A
13-bit DPWM which combines a 7-bit counter-comparator block with a 6 -bit second-order

Maha AlDahmi, Omar Al Ahmad, Ezzat Ahmad
AlAin Distribution Company, UAE
Abstract-Enhancing capacitor banks' performance in Al Ain Distribution Company (AADC) network
will lead to power factor and related network improvements. The aim of this study is to optimize the
existing capacitor banks and obtain the maximum benefits by evaluating the capacitor banks' status
&condition, controllers' settings, and analyzing their functionalities in conjunction with network
S1-1002 assets based on real time measurements. The analysis was divided into two different approaches
16:00-16:15 based on capacitor banks locations in AADC network, as the capacitor banks operation concept is
totally different between the banks installed in primary substations (directly connected to 11kV
busbars consisting of several stages) and the ones installed at 11kV overhead lines (OHL) of one
stage and usually smaller in capacity size. In this paper, the classification is done based on network
characteristic and banks' controller types as well as operational concept. AADC has more than 350
capacitor banks installed in primary substations and 11kV OHLs with approximately 930MVAR
installed capacity providing high potential of reaching high power factor if operated and controlled
well. The paper also explores the economic impact of the expected capacitor banks operation
enhancement by saving energy and reducing power losses.

Abstract-With the advent of technology, Flexible AC Transmission Systems are popularly used to
increase the power transmission capacity of transmission lines and for optimum utilization of power
S1-0035
system capability which result into the substantial change in system dynamics. Change in system
16:15-16:30
dynamics has an impact on protection of power system as there is substantial change in the net
impedance of transmission line due to FACTS devices which gives rise to overreaching or
underreaching problem in distance protection scheme. In this paper, performance of distance relay
in the presence of Static Synchronous Series Compensator (SSSC) is studied under various fault
conditions. A 400kV, 300km transmission line is designed and simulated using MATLAB/SIMULINK
software and results are presented to show influence of SSSC on mho characteristic of distance
relay.

Design Equation for Directly Computing Two Gains of PR Controller
Jessada Pan-On and Wirote Sangtungtong
Suranaree University of Technology (SUT), Thailand
Abstract-This paper formulates the design equation which directly computes two gains of the
S1-0086 proportional-resonant (PR) controller regulating grid current emitted from single-phase PWM
16:45-17:00 inverter with passive LCL filter Such a control system that is without grid-voltage sensing becomes
the sixth-order one Thus there is inconvenience against tuning the controller gains and it is also
rather impractical to tune them by trial-and-error When the PR gains are two unknowns, partial
pole assignment and consideration over the closed-loop characteristic equation dispense the design
equation which provides more effectiveness of tuning them Simulations assert that utilization of
the proposed design equation is able to enhance performance of response
Speed Sensorless Vector Control of Parallel Connected Induction Motor with Anti-Windup
Integral-Proportional Speed Controller
Fanniesha Hamada, Faiz Husnayain, Feri Yusivar
Universitas Indonesia, Indonesia
Abstract-This paper presents speed sensorless vector control with anti-windup integral-proportional
S1-0074 (AWIP) speed controller of parallel connected induction motor fed by single inverter. Luenberger
17:00-17:15 observer is adopted to estimate rotor flux, stator current, and motor speed. Vector control with
average and difference mechanism works to overcome unbalanced load torque. An AWIP speed
controller is employed to improve the degradation of system performance due to windup effect such
as large overshoot, slow settling time, delayed response and could even destabilized system. It will
be compared to anti-windup proportional-integral (AWPI) speed controller to verify the reliability.
Simulation results show that speed sensorless vector control with AWIP performs better to eliminate
overshoot in transient response.

Abstract-This research demonstrated the design technique and sensor building for liquid level
17:15-17:30
measurement by applying microstrip parallel coupled lines. The design and building of the coupled
line with a microstrip had coupling at -10 dB and 200 MHz of frequency. The water level for testing
was 0-20 cm to check the frequency response of the coupling from 100 MHz -1.5 GHz. In accordance
with the experiment, it was found that coupling with different levels of water provided the same
result. This technique was easy to follow as the sensor had a small size and was inexpensive.

Abstract— The cantilevered piezoelectric vibration energy harvesters are operated in their first
mode and analysed as Single Degree of Freedom (SDOF) systems. In literature, models were
developed with piezoelectric material spread over the entire length of the substrucutre beam. In
cantilevered arrangement, strain in the harvester beam is maximum at fixed end and minimum at
the free end. So it is not cost effective to use piezoelectric materials for full length of the
substructure beam. A lumped electromchanical model for output power from piezoelectric vibration
energy harvester beam with partially covered piezoelectric material is proposed. The governing
equations of motion for the coupled electromechanical model are deduced using Newton's laws of
motion and Kirchoff's current law. A novel method using a correction factor to find equivalent
stiffness properties of proposed harvester beam is studied there by equations for output power
from the harvester are deduced. The model is developed considering transverse harmonic base
excitation and linear system parameters. Experiments are performed to validate the results from
electromechanical model. The performance of harvester is investigated for different tip masses. The
analytical model results and experimental measurements shown good agreement in resonance
frequency, relative displacement and output power.

Abstract-With the flexibility modification of thermal power plant, the minimum technical output of
units has been reduced. Different kinds of operating modes can be chosen by operators of power
S1-0020
grids, which will influence the frequency regulation of power grids. The mathematical model of
13:00-13:15
reheater steam turbine and load frequency control (LFC) are established considering flexibility
modification of thermal power plants. Two scenarios are created and simulations are carried out.
The results indicate that with the increase of units investigated in power system, the frequency
deviation decrease obviously in both a stand-alone control area and two interconnected control
areas. The conclusions presented here provide some guidance on operation of thermal power plants
in regions to reduce the amplitude of frequency oscillation.

Abstract-Energy savings in buildings as a goal in recently established buildings either residential or
commercial has been nowadays paid much attention by many researchers, designers, and decision
makers due to the need of reducing energy demand and global warming issues. This challenging goal
is affected by several factors and roles which play important roles by which this goal is affected.
Those factors in most cases are difficult to be treated by one method or design. Many proposed
systems have been introduced for many years; their performance(s) have varied percentage(s) of
achievement in terms of energy savings. In this setting, such a review paper could help much to
S1-0046 draw a clear plan for researchers and buildings’ designers to follow and get them directed to best
14:00-14:15 and easiest systems. However, many review papers have been published which included many
limitations, e.g., some review papers focused only on residential buildings. In general, there is a
need to give an overview of reviewed papers with taking into account many factors and policies
together with strategies applied. In this setting, it is understood that different designs have
produced different levels of performance being achieved. In this review paper, Building Energy
Savings Strategies and Systems (BE3S) are reviewed. Different points of views have been considered.
For example, lighting control systems, buildings’ retrofitting systems, and occupancy profiles related
systems have been reviewed. This paper has also included different types of buildings on which
strategies and systems have been applied. Reviewed papers are collected from top-tier journals
published by very well-known publishers which are IEEE, Elsevier, Emerald, MDPI, and ACM. Indexing
services adopted in this BE3S paper are Scopus and WOS. BE3S paper has only considered last 20
years providing a summary of recently designed strategies achieving semi-optimal performance(s) in
terms of energy savings in buildings.
