Hierarchical cooperative dispatching system for output of photovoltaic power station cluster and control method thereof

Abstract

Disclosed is a hierarchical cooperative dispatching system for output of a photovoltaic power station cluster and a control method thereof. The system includes: a data acquisition layer, deployed at each photovoltaic power station end, used for collecting power station basic data in real time; a cluster cooperative prediction layer, used for generating short-term and ultra-short- term output prediction curves of a cluster; a hierarchical optimization dispatching layer, used for solving for an output reference point of each power station according to the prediction curves and a dispatching instruction; and a local execution control layer, used for generating a power adjustment instruction for an inverter according to a deviation between real-time prediction data and the reference point. The method includes steps of data acquisition, cluster prediction, hierarchical optimization, and local tracking. According to this disclosure, coordination between global optimization and rapid response is achieved through a hierarchical architecture.
