Optimal regulation for loop-closing operation in a distributed generation integrated system

Abstract

As an effective measure to improve electricity supply reliability, loop-closing operation is widely used in distribution network. Due to various distributed generation were involved into distributed system, problems such as circuit breaker overcurrent may arise if loop-closing and DG status were not well coordinated. In this paper, a new loop-closing control model which including distributed generation is proposed, and the genetic algorithm with diversity control approach is used to solve the problem. A typical case with two feeders and three distributed generations is used to illustrate the performance of the proposed method.
