摘要：
Coordinated charging loads of electric vehicles (EVs) can be integrated into the dispatching system and improve the operation of power grids. In this paper an EV coordinated charging hierarchical control strategy considering renewable energy generation integration was proposed. By solving a two-stage load-shifting optimization problem the EV charging load guiding curves can be obtained at the main control center. The charging loads of EVs were controlled to follow the guiding curves at the sub-control centers with centralized/decentralized control strategies according to actual situations. The abandoned rate constraint was considered to improve integration of renewable energy. Simulation results show that the proposed hierarchical control strategy is expandable. By merging different control methods the objectives of load following and load-shifting are achieved respectively at sub-control centers and the main control center considering local conditions. © 2016, Power System Technology Press.
