OPTIMAL PLANNING FOR DG INTEGRATION WITH DISTRIBUTION NETWORK TO EXTEND LOADABILITY LIMIT AND IMPROVE NETWORK PERFORMANCE USING CPF BASED VOLTAGE STABILITY INDICES

Abstract

Voltage stability becomes an important parameter looking to the contornos demand growth over existing network in last few years. Power distribution network required proper planning and analysis to maintain consistent good efficient and fulfil various power quality constraints. Moreover, distributed generation connected near to load end requires deep planning and analysis to improve performance of the network. In this paper voltage stability analysis has been done based on continuous power flow method where buses weak buses have been identified. The main objective of is to analysis the influence of DGs on voltage stability of radial distribution network. Distributed generators planned to deployed on these weak buses to strengthen the network considering future load growth. Optimal sizing of DGs has been done using Genetical Algorithm. Proposed analysis has been done using IEEE-33 bus system.
