电动汽车电池交换站与微网的协调优化调度.

Aiming at the problem that the randomness and uncertainty of the load of Battery Swap Station(BSS)of electric vehicles lead to the increase of the peak-valley difference of the load in the micro grid .a two-layer optimal scheduling method based on real-time electricity price was proposed for the coordination between BSS and the microgrid. The uncertainty model of electrical changing demand is established in BSS. Based on the time-of-use electricity price of the main network and the conventional load of the microgrid, a method for determining the real-time electricity price in the microgrid is proposed, and a coordinated double-layer optimal scheduling model of BSS and microgrid is established. The Cplex solver was called by Yalmip to solve the upper and lower models, respectively, to obtain the optimal output of the controllable micro-source inside the microgrid and the optimal charge-discharge plan of BSS. Finally, an example is given for a microgrid. and the results show that the proposed optimization method can improve the benefits of both parties and realizes the peak-shaving and valley-filling of the total load in the network.
