| 摘要: |
| 对光伏-储能联合发电系统的运行模式进行了研究，包括整体运行模式、储能旁路模式、储能独立运行模式。提出光伏-储能联合发电系统的拓扑结构和潮流定向控制策略。基于某100 kWp光伏发电站的实际历史运行数据，进行了仿真验证，通过配备储能系统，增加了系统的可控性和可观性，实现对电网的友好接入；同时改善了系统输出特性，实现部分程度的“削峰填谷”，大幅降低光伏微网系统对电网输电容量的需求。 |

| Abstract: |
| The operating modes of photovoltaic／energy-storage hybrid system are analyzed，including whole system mode，energy storage bypass mode and energy storage support mode. Its topology is proposed with the flow direction control，which is verified by the simulation with the operational data of a 100 kWp photovoltaic system. The integration of photovoltaic system and energy storage system increases the system controllability and grid-connection flexibility，improves the system output characteristics of load response，and reduces greatly the system requirements for grid power transmission capacity. |
