A Review of Renewable Energy Based Distributed Generation in Electrical Power System

Abstract-It is possible to describe distributed generation as power generation by small scale generating units installed in distribution systems. There is a steady growth in the penetration of distributed generation (DG) units into electric distribution systems. DG allocation is the process of finding the optimal type, location and size of DG units. The allocation of DGs is a hot research field and poses a difficult problem in electrical power engineering. This paper discusses the recent research work on the issue of DG allocation from the point of view of their optimization algorithms, targets, and decision variables, type of DG, implemented limitations and type of modeling of uncertainty used. In this research an overview of DG types and various DG technologies are highlighted. Some DGs challenges ahead with current drive towards smart grid networks is also discussed. The research gaps are defined on the basis of their views on current research work and some helpful suggestions will be made for future research on DG allocation. The author strongly believes that this paper could be beneficial in the related field for researchers and engineers.
