Reliability Enhancement of Electrical Distribution Systems Considering Active Distributed Generations

Abstract

The electrical distribution system is more prone to failure for a variety of causes, according to survey data by different electric companies around the world. The usage of DG, or distributed generation, has been expanding for some time, improving the reliability of the consumer electric supply. The placement of DGs is crucial for enhancing reliability. By choosing the best location for DGs, this chapter aims to increase the reliability of the distribution network. This is done in this chapter by outlining a process for choosing DG locations. Additionally, an objective function that displays different costs related to distribution networks using DGs has been established. Primarily Reliable Indexes are used in this function. Because of this, if the reliability indices are maintained below their threshold values, optimizing the objective function yields optimized values for the costs associated with the objective function. For the optimization, the flower pollination optimization approach was applied. On the Roy Billinton test system bus-2, this was carried out. The same issue was addressed using both differential evolution and teaching learning-based optimization techniques. To support increased expenditures on DGs, an analysis of costs and benefits was conducted. © 2024 by The Institute of Electrical and Electronics Engineers, Inc. All right reserved.
