摘要

为协调电力系统供需侧功率调度,平滑系统中的功率波动,提出一种基于电网侧功率调度的光-储整合系统拓扑架构及其控制策略。所提拓扑架构可实现相间与相内的功率均衡,进而实现光伏单元与储能单元之间的能量互补。其次,通过深度挖掘模块化变换器的控制自由度,结合典型的运行场景与控制需求,对整个系统的协同控制策略进行设计。所提光-储整合系统及其协同控制策略既可利用储能平抑光伏发电的功率波动,也可根据电网需求输出相应的功率,可增强系统的实用性。最后,通过实验验证了所提出的整合系统拓扑及其协同控制策略的有效性。

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.
