Research on Energy Management Strategy of Integrated Photovoltaic and Energy Storage Power Station

The integrated photovoltaic and energy storage power station is a new type of charging device that can efficiently exploit renewable energy sources and reap significant financial rewards. However, the energy management of systems incorporating new energy sources is more complicated because of the stochastic nature of load demand and the intermittent nature of PV supply. In order to ensure stable system operation and maximize economic benefits, this paper proposes an energy management strategy for an integrated photovoltaic and energy storage power station that takes into account the state of charge (SOC) of energy storage, the price of electricity, and the power difference within the optical storage and charging system. It also flexibly controls the energy flow within the system by judging the power difference within the system and the power consumption period. Finally, two cases are shown to confirm the proposed energy management strategy's efficacy.
