Allocation of DG Units in Distribution System to Minimize Reactive Power Loss

Abstract

In today's scenario, in order to meet load demand in the distribution system, DG units play a key role in reducing real and reactive power losses. A rise in the demand for the distribution system at the loading centers has been overcome by growing in power generation. One solution to meeting the necessary load demand is to mitigate loss of power in the distribution system. Real Power can be maximized across the network by decreasing the system's reactive power losses. This paper introduces a new analytical approach as well as a new Power Voltage Sensitivity Factor (PVSF) constant that defines the optimal DG size and position. An objective function is utilized to determine the loss of reactive power when reinforced with distributed generators (DGs). To demonstrate the feasibility of the proposed approach, the radial distribution system has been evaluated on the standard IEEE 69-bus and outcomes obtained are contrasted to other approaches.
