Aggregation-based Self-dispatch of the Virtual Power Plant with Massive Controllable Batteries

There are massive small size distributed batteries that possess great potential value to provide energy and regulation services in modern power system operation. To confront the curse of dimensionality caused by a large population of batteries, a polytope-based aggregation approach considering the uncertainty of batteries’ initial energy is proposed in this article, which can formulate the maximum inner approximate feasible region and equivalent cost parameters comprehensively. Furthermore, an aggregation-based energy management approach of the virtual power plant composed of massive controllable batteries is proposed. The effectiveness and superiority of the proposed approach are verified through numerical simulations, and the proposed aggregation method can yield a comprehensive energy and regulation capacity dispatch plan with computation efficiency.
