An Analytical Approach for Optimal Allocation of DG Unit in Distribution System

The advancement of Decentralized Generators or Distributed Generation (DG) introduces new changes to the long-established power system. Distribution Generation plays a prime function in distribution system by upgrading the systems reliability, curtailment in power losses and uplifting the voltage profile. This paper proposes an analytical approach to apprehend the optimal size and optimal allocation of DG entities in reconfigured distribution network to alleviate the losses. Lack of proper connection and sizing of DG causes the power losses to enhance and also might cause the voltage to operate beyond the allowable limit. The DG penetration level is also taken into account. The propound method is applied on the standard IEEE 85-bus test system at three different load levels using analytical approach The obtained results are analogized with the other techniques of DG allocation and the propound method is found to be more efficient in terms of upgradation in voltage profile and the curtailment in real power losses.
