Strategic Integration and Configuration of Distributed Generators Units in Distribution Networks: An Overview

Abstract

The distribution system has been paying more and more attention to distributed generation (DGUs) since a few years ago. The main causes of (DGUs) in distribution systems are increased electric demand, a deregulated energy market, and a congested transmission network. These factors ultimately lead to a decline in system performance. There's also an increasing push to cut greenhouse gas emissions. Proper placement and dimensioning are crucial for efficient utilization of DGUs. The system's current performance will be deteriorated and losses would increase due to improper DGUs location and size. However, optimal placement will reduce power loss, increase voltage stability, and maintain a consistent voltage profile in the distribution system. This paper reviews DGUs, the technical developments in DGUs, and several optimisation methods for the optimal placement problem. and size.
