Abstract

In order to coordinate the power scheduling on the supply and demand side of the power system and to smooth the power fluctuations in the system, the paper proposes a topological architecture of a photovoltaic-storage integrated system based on grid-side power scheduling and its control strategy. The proposed topology can realize inter-phase and intra-phase power balancing, and then realize the energy complementarity between PV units and storage units. Secondly, the cooperative control strategy of the whole system is designed by exploring the control freedom of the modular converter and combining the typical operation scenarios and control requirements. The proposed photovoltaic-storage integrated system and its cooperative control strategy can not only utilize the energy storage to smooth the power fluctuation of photovoltaic power generation, but also output the corresponding power according to the grid demand, which enhances the practicality of the system. Finally, the effectiveness of the proposed integrated system topology and its cooperative control strategy is verified by experiments.
