A Novel Method for Determining Optimal Location and Capacity of DG and Capacitor in Radial Network Using Weight-Improved Particle Swarm Optimisation Algorithm (WIPSO)
Active and Reactive power supplied by the distribution side components plays a significant role in maintaining the power supply during the peak load and excess load conditions. Compensating elements are excessively utilized to provide necessary power support (i.e active and reactive power) and to share the peak load demand. In this paper we have proposed optimal bus number where the capacitor to be placed and also its size. Placement of capacitors additionally will reduce the losses and will also maintain the required voltage profile within limits. This paper proposes Weight-Improved Particle Swarm Optimization Algorithm (WIPSO) for optimal location (siting)and sizing of compensating devices. This proposed method is tested in detail on various systems and comparative study is done before and after installation of distributed generators. Results illustrates improvement in network voltage profile, reduction in system real and reactive power loss and reduction in cost of service provided by these local devices.
