Utilizing capacitor banks is very conventional in distribution network in order for local compensation of reactive power. This will be more important considering uncertainties including wind generation and loads uncertainty. Harmonics and non-linear loads are other challenges in power system which complicates the capacitor placement problem. Thus, uncertainty and network harmonics have been con...

in practical situations, distribution network loads are the mixtures of residential, industrial, and commercial types. this paper presents a hybrid optimization algorithm for the optimal placement of shunt capacitor banks in radial distribution networks in the presence of different voltage-dependent load models. the algorithm is based on the combination of genetic algorithm (ga) and binary part...

An experimental exploration of using an Electronically Controlled Capacitor (ECC) in the supply system of a two speed single phase induction motor drive is presented. The ECC solution and the method with solution with a fixed value capacitor are comparatively analyzed in terms of efficiency and maximum torque availability. The losses and the over-voltages due to the electronic commutation are a...

This study introduces new tuning technique for the PID control scheme and its application to regulate the voltage magnitude and the frequency of wind energy conversion system (WECS). The developed technique is stem from blending the ant system optimization method with Takagi Sugeno (T-S) fuzzy system approach. The optimum relationship between the PID controller gains and the parameters of T-S f...

In larges electrical system used in industries, office builidings, or hotels, capacitor banks are usually utilized to compensate the required VAR absorbed by the loads. As the nonliniear loads are increasing rapidly, the risk of resonance phenomenon occured is becoming higher as its terminal voltages are not anymore sinusoidal. On the other hand, many customers have become aware to the problems...

1. Introduction Life-cycle cost reduction of transmission and distribution systems is becoming increasingly important to adapt to global changes resulting from factors such as electricity market liberalization, electricity industry deregulation , environmental protection issues, as well as various emerging technologies developed using information technology advances. Technical requirements for ...

Due to the rising power demand and increasing population worldwide, electrical power networks have been extensively growing and striving to satisfy the escalating loads. This necessitates the need for using Flexible AC Transmission System (FACTS) devices which have become indispensable during normal and abnormal operating conditions. This paper investigates the impact of using series FACTS devi...
