System impact analysis of Renewable Distributed Generation on an existing Radial Distribution Network

This paper analyzes the impact of Renewable Distributed Generation on a 4.02 MVA Radial Distribution Network of a particular area of Gujarat state, India. Distribution System software simulation of existing Network revealed severe voltage regulation problems in major portion of the Network, overloading of few sections and high losses. A methodology has been developed and presented in this paper for determining appropriate locations for integration of Renewable Distributed Generators within the Distribution Network with the objective of improving voltage profile and reduction in losses. After the integration of Renewable Distributed Generation in the Network as per the methodology developed, the simulation results reveal that the minimum voltage in the Network is within the permissible regulatory limits and significant loss reduction is achieved. Also an advantage is increased Network reserve capacity to cater additional load with the same existing Network.
