One of the most important methods in loss reduction and controlling the voltages of distribution systems is the utilization of the fixed and switched capacitors. To do this, real modelling of the system in actual operational conditions including unbalanced or balanced loading and for actual feeder structure, ie, radial/meshed configuration, are required. In this paper, a new technique for findi...

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...

This paper presents a genetic algorithm-based method to determine coordinated voltage control in the unbalanced distribution radial system distributed generators. The coordinated voltage control has been done with DGs reactive power control and OLTC operation. The result indicates that involving DGs reactive powers in the voltage control will result in a reduction of number of OLTC operations a...

The application of power semiconductor devices in the area of power electronics and power system are the key factors which kindle the power quality problems particularly the harmonics, burden of reactive power and neutral current due to unbalance. The above citied power quality problems are predominant due to wide usage of 1-φ / 3-φ , linear and nonlinear loads which are fed from three phase fo...
