Optimal schedule of photovoltaic-battery hybrid system at demand side

Abstract

Renewable hybrid systems, which can generate power from solar or wind with low cost, is commonly installed in remote areas. When some areas get grid connection, customers installed the hybrid system can earn cost savings if taking part in demand response programs. In this paper an optimal energy management for a grid connected photovoltaic-battery hybrid system is proposed to sufficiently utilize the solar energy and to optimally dispatch the power flow under into the time-ofuse program. The management of power flow aims to minimize electricity bills subject to a number of constraints, such as demand balance, solar energy, and battery capacity. An optimal control method (open-loop) is developed to schedule the power flows of the hybrid system over 24 hours. As shown in results, optimal solution of scheduling the hybrid system can be obtained with great bill savings.

Energy management of small-scale PV-battery systems: A systematic review considering practical implementation, computational requirements, quality of input data and battery degradation

“…Past studies in the area of PV-battery optimisation and selfconsumption have used low resolution PV and demand data, typically of either 30 minutes [8,[44][45][46][47][48] or 1 hour [26,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62]. This is mainly due to the unavailability of data with finer resolution, since household smart meters are usually set to record data in 30 minutes intervals.…”
