大型光伏电站有功功率控制策略研究

Research on active power control strategy of large photovoltaic power plant

针对光伏电站有功功率控制策略不完善而导致发电量较低的现状,本文提出了一种光伏电站有功功率优化分配策略,将设定功率按照一定的优先策略分配至各光伏逆变器,以提高光伏电站对电网调度指令跟踪的准确度,最后,通过对一座光伏电站进行现场测试,验证有功功率优化策略的可行性和有效性。

Aiming at the imperfection of active power control strategy in photovoltaic power plants, the current generation capacity is low. In this paper, an optimal allocation strategy of active power of photovoltaic power station is proposed, which is allocated to each photovoltaic inverter in accordance with a certain priority strategy to improve the accuracy of the power power tracking of the power station. Finally, the feasibility and effectiveness of the strategy is verified by active power control test of a practical PV power station.
