Optimal Sizing for on grid Residential PV-Battery System Due to the Peak Load of Electricity Grid

This paper proposes a new method for sizing a residential on-grid PV battery systems based on peak of electricity grid. Nowadays PV battery systems are usually connected to the grid and renewable electricity generation considered as backup. Minimizing cost is one of the most important goals for this systems. For obtaining electricity demand a residential section simulated by HOMER software. According to announced peak time of power gird, electricity demand in peak time is calculated. Maximum demand in peak time provides Battery and PV size. Since the electricity provides with this system is expensive using PV battery system is reasonable.
