Abstract

The configuration of energy storage with reasonable capacity in the photovoltaic microgrid is a powerful way to promote the local consumption of distributed photovoltaic and improve the efficiency of photovoltaic system. DSM can effectively reduce grid investment and become an important regulation means for efficient operation of power system. The main innovation of this research is to consider the utilization of demand side resources in microgrid planning, which is rarely deployed in previous studies. Firstly, the models of renewable energy output characteristics and energy storage SOC characteristics are established, and the demand response mechanism is analysed; Secondly, taking the minimization of the comprehensive cost of the system as the objective function and the energy balance, equipment characteristics as constraints, a collaborative planning model of PV-Battery storage system for microgrid considering demand response is constructed. Finally, the rationality and effectiveness of the proposed optimization model are verified by the actual data of a microgrid in Fuzhou.
