Optimal Allocation of a Hybrid Renewable Energy-Storage System for Supplying Egyptian Distribution Networks Using Discrete Jaya Algorithm

The proper location and size of the distributed generators enhances its benefits in the distribution networks. Thus, this paper presents an optimal proposed allocation procedure for hybrid renewable energy-energy storage system to improve the operation characteristics of the electrical distribution system. A proposed discrete Jaya algorithm is used to estimate the optimal allocation of the hybrid renewable energy-energy storage system by applying both single and multi-objective functions. The objective functions improve the voltage profile and minimize both active and reactive power losses of the electric distribution system. Backward/forward sweep method is used for the load flow calculations. Numerical application is applied to the electric distribution system of Mersi-Matrouh City which is a part of the Egyptian distribution system. This paper also presents a design of a hybrid renewable energy-energy storage system which depends on wind energy as a source of renewable energy and depends on the proton exchange membrane fuel cell as energy storage system to completely supply the electric distribution system in a reliable way. The results prove the capability of the proposed algorithm in finding the optimal allocation of the hybrid renewable energy-energy storage system to improve the system voltage profile and minimize both active and reactive power losses.
