Multi-Objective Energy Management of a Grid-Connected Photovoltaic-Wind-Battery Hybrid System using Deterministic Approach

This paper develops a multi-objective energy management strategy for power dispatch of the grid-tied photovoltaic (PV)-wind turbine (WT)-battery system to supply an industrial load. The aim is to minimize electricity cost while participating to the Time of Use Demand Side Management program, which is an important control parameter in this model to assist utility companies to control the grid in terms of security, reliability and efficiency. This issue is considered as a deterministic problem and solved using linear programming. In order to demonstrate the effectiveness of the proposed approach, comparison with other methodology of control is carried out. Simulation results show that the developed control reduces the operational cost of the hybrid system and allow consumers to benefit from a significant income by maximizing the selling power to the utility grid.
