Malaysia is a country that is surrounded by numerous oceans that are able to be a renewable energy resource for betterment of human life. This research is proposed to design, model and analyze a portable single-phase linear permanent magnet generator for wave energy conversion (WEC) that is works with the local wave parameters. In comparison with a rotary generator, the linear generator is found preferable...
A proportional-integral-derivative (PID)-based power system stabilizer (PSS) is connected to the excitation system for stability enhancement of a single machine power system. In this paper, an auto-tuning of PID controller with PSS has been proposed to damp out the low frequency oscillations in the synchronous machine. Tuning the PID gains of the controller is considered as the optimization problem,...
This paper shows the productivity of grid-connected photovoltaic systems, to plan future investments in the region around Klagenfurt, Austria. To evaluate the usage of grid-connected PV systems, a methodology based on mainly three factors is presented. These factors are yield factor, capacity factor and cost of energy. The analysis is done by a model based on monitored PV data and meteorological data...
In today's advanced communication, electronic and electrical technology, the used of Motor Protection Relay (MPR) has become preferred. MPR will help maintenance engineers in controlling, protection and monitoring of the electric motors. Therefore, the history event recorded by the MPR enables the implementation of the predictive maintenance. In addition to this advance technology, there appeared...
Wind farms are one of the most indispensable types of sustainable energies which are progressively engaged in smart grids with tenacity of electrical power generation predominantly as a distribution generation system. Thus, rigorous protection of wind power plants is an immensely momentous aspect in electrical power protection engineering which must be contemplated thoroughly during designing the...
WLAN network is the most popular wireless network used for various electronic devices to exchange data. Electronic devices such as smart phone, laptop, printer, digital camera and smart TV are using the Wi-Fi antenna to exchange data wirelessly. However most of the Wi-Fi antenna is isotropic antennas which transmit and receive Wi-Fi signal omnidirectional. According to current IEEE 802.11n standard,...
Optimization techniques are become more popular for the improvement in control of Three Phase Induction Motor (TIM). Also the Volt/Hz (V/f) control and space vector pulse width modulation (SVPWM) are used to reduce the harmonics level related to other control and modulation techniques. This paper deals with the tuning of PI controller parameters to be used in TIM. Particle Swarm Optimization (PSO)...
The effects of electromagnetic fields(EMF) due to high voltage line on the parallel pipeline are not a common issue nowadays. The EMF will bring up some pipeline problems and safety issues. There are only a few of previous studies about EMF effects consider in the lightning fault parameter and study in term of currents. This means the EMF effect of the transmission line to the pipeline still not completed...
This paper presents the application of binary firefly algorithm (BFA) in obtaining the optimal location of battery energy storage systems (BESS) in photovoltaic generation integrated radial distribution network in order to mitigate the voltage rise problem. The optimization process aims to obtain the optimal location by minimizing the voltage deviation of the PVDG bus. A BESS placement (BP) vector...
At present, wind energy industry is facing major design constraints in boosting the power output. These can be overcome by setting up the right turbine at the right place. This paper proposes an optimized layout design of a wind farm by using Definite Point selection(DPS) and genetic algorithm, which can minimize the cost per unit power and minimum wake effects, while sustaining the obligatory space...
On behalf of the Organizing Committee, I would like to welcome all participants to the 2014 IEEE International Conference on Power & Energy (PECON 2014).
This work presents a standstill (offline) parameter identification method for synchronous machines with dual field excitation on the d and q axes of the rotor. Such machines have applications as turbogenerators and synchronous motors. One machine with an equivalent model is the divided winding rotor synchronous generator, which is a round rotor machine that was proposed by Soper and Fagg. A methodology...
Reduction of active power loss is one of the main functions that are carried in power system control centers. The main purpose of transmission systems is efficiently handling power from generation stations to load centers. Yet, a considerable amount of power is lost in transmission network components. As a corrective action, power flow redistribution in transmission lines using appropriate power flow...
The electricity waste is severe especially in large organizational buildings where the use of air conditioners, fridges and electrical motors are rampant. Due to lack of energy saving consciousness, users may not switch off this equipment after use. Thus, it would be an advantage if there exist a system that will be able to identify the appliances from one place without the residence having to go...
This paper is concerned with the heat transfer properties of transformer oil suspensions of Al2O3 nanoparticles. Nanofluids are prepared by mixing and dispersing of nanoparticles with the base oil using magnetic stirrer and ultrasonic homogenizer. To decrease the effect of van der waals attraction force between nanoparticles and improve the stability of resultant nanofluids, a surfactant is used....
