Photovoltaic power station cluster cooperative intelligent control system and method

Abstract

The application discloses a photovoltaic power station cluster cooperative intelligent control system and method, and relates to the technical field of photovoltaic power station control. The application solves the technical problems of insufficient photovoltaic cluster cooperative control and poor long-term adaptability. The application comprises an instruction construction module, a step locking module and a deviation closed loop module. The instruction construction module constructs a P-V curve feature set of each substation under different working conditions by a cluster coordinator, and filters a global optimal voltage interval adaptive to the current working condition, and combines and issues the target power. The step locking module executes variable step voltage disturbance by the substation until the power converges to the target threshold and the voltage is locked. The deviation closed loop module monitors the power deviation by the substation, uploads data when the trigger condition is met, and updates the feature set accordingly. The application improves the cluster control precision and power generation efficiency, and realizes system closed loop self-learning and full life cycle robustness.
