This paper presents the design process of a slotted TORUS axial-flux permanent-magnet motor suitable for direct drive of an electric vehicle through sizing equation and Finite Element Analysis. AFPM motor is a high torque density motor which can be easily and compactly mounted into the automobile's wheel fitting the rim perfectly. A double-sided slotted AFPM motor with 6 rotor poles for high torque...

Welcome to all participants of the 2012 IEEE International International Power Engineering and Optimization Conference (PEOCO 2012). I am very glad to know that this conference has received participants from many parts of the world. I hope this conference will provide a platform to the share knowledge and disseminate research findings among the delegates.
In this research, an optimization of monthly tilt angle for solar panels for five main sites in Malaysia is conducted. The optimization method is based on the Liu and Jordan model for solar energy incident on a tilt surface. As a result, applying the monthly optimum tilt angle, increases the collected yields of the PV module/array in Kuala Lumpur, Johor Bharu, Ipoh, Kuching and Alor Setar by 5.03%,...
One configuration of a hybrid electric vehicle (HEV) is the split-axle parallel architecture, which enables existing vehicles to be retrofitted into a hybrid vehicle with minimal modification - achieved by placing electric motors in the hub of the otherwise non-driven wheels. The present work describes different HEV configurations and identifies specific operating modes of the split-parallel architecture...
Locating the suitable locations in power system for the purpose of Flexible Alternating Current Transmission System (FACTS) devices installation can be realized via wide variety of techniques, and commonly applied by many researchers are sensitivity analysis and optimization approach. On the other hand, there are also various power tracing techniques have been invented by researchers, but their application...
Utilization of renewable energy resources is gaining momentum in several countries. Establishment of distributed renewable energy plants would cover the regional needs of the country besides sharing the power distribution with other parts of the country. For implementing this establishment, the country is proposed to be divided into several power regions named as cells or nodes and one or more renewable...
Temperature, especially the hot spot temperature (HST) and top oil temperature (TOT), has played the important rule and became the most effective factor in determination of the insulation life of the transformer. The prediction of HST and TOT is very important for estimating the loss of life (LOL) of the transformer in power system. Therefore, an accurate technique is needed for solving the thermal...
This paper present the speed sensorless Field Oriented Control (FOC) of parallel- connected dual permanent magnet synchronous motor (PMSM) fed by a single inverter. The speed for both motors are estimated by using Model Reference Adaptive System (MRAS) scheme. In this scheme, two different models are used which are reference model and adjustable model. The motor is set to be a reference model and...
In islanding mode, system frequency is severely disturbed due to imbalance between generation and load demand resulting in overloading or loss of generation cases. In order to cope with these events, under-frequency load shedding scheme (UFLS) is applied to stabilize the frequency. This paper presents an intelligent under frequency load shedding scheme implemented on mini-hydro operating in islanded...
This paper describes a heuristic method for determining minimum loss configuration of radial distribution networks. The reconfiguration process starts with a power flow of the system with all candidate switches closed. In this meshed status, the choice of switches to be opened is based on sensitivity analysis in first procedure and branch exchange operation in second procedure. The solution algorithm...
This paper review the effectiveness of the parity space approach to identify faults or disturbance in a system. The most commonly used is the observer based procedures, and redundancy relationship method. This involves analytical mathematical analysis of geometry and bilinear algebra. Then, technological advances which require complex computation such as artificial intelligence and genetic algorithm...
One of the challenge in islanding operation is to maintain frequency stability when generation is less than demand. This paper presents a new Under-Frequency Load shedding scheme for an islanded distribution network. The scheme is based on an adaptive and intelligent load shedding techniques. This proposed scheme is able to conserve power system collapse even for large disturbance and events in the...
