Optimal Energy Management Strategy in A Grid-Tied System with PV, Wind, and ESS Considering Environmental Aspect

The principal goal of this study is to explore the performance of a residential grid-connected system which relies on economic and environmental aspects. A wind turbine (WT), photovoltaic generator (PV), and energy storage system (ESS) with reducing the cost of energy to pay the utility grid (UG) under Time-of-Use (TOU) pricing is conducted to investigate the efficiency of the system. The model can provide an opportunity for the consumer to sell the energy to the supplier, especially during high price periods. As the battery has a substantial effect on the operational cost of the system, the daily operating cost of the battery and the effect of the degradation are incorporated in the energy management strategy (EMS). The simulation results prove the effectiveness of the suggested approach in which the new objective function achieves the maximum cost-saving compared to a baseline technique as well as the lowest Green House Gas (GHG).
