Multi objective DG and RPC planning of radial type distribution network considering economic ViewPoints

DG penetration is continuously increased across distribution network not only to reduce carbon emission, but also to enhanced performance of the distribution network. In a restructured environment any distribution utility need to address DG placement and sizing problem to find a cost effective solution for the specific investment. Most of the authors have attempted to solve the problem based on real power loss reduction across the network. Some authors consider voltage stability based analysis for increased loadability of network with real power loss. However, optimal reactive power compensation also need to be incorporated for a cost effective solution. In this paper an attempt has been made to address various types of DG and RPC units citing and sizing problem with multi-objectives consists real power loss reduction, voltage stability improvement. A new approaches includes development of cost function to find cost-effective solution for distribution network. Evolutionary based Genetic Algorithm used to optimize objective function. Proposed algorithm is tested on IEEE-33 bus radial distribution system.
