New Energy Double-layer Consumption Method Based on Orderly Charging of Electric Vehicles and Electricity Price Interaction

Abstract

With the new energy access to distribution network, the problem of new energy consumption becomes more and more obvious. Electric vehicle load has transferable characteristics, and it is helpful to realize new energy consumption by using electricity price guidance. However, at present, the above aspects have not been considered in electricity price formulation, and the interaction between electric vehicle (EV) response and electricity price has not been considered. To solve this problem, in this paper, a new energy double-layer consumption method based on orderly charging of EV is put forward. Firstly, the EV load model is established, and then the electricity price model considering the fluctuation of new energy is established as the initial price curve of electric vehicle orderly charging which will be updated later according to the response of electric vehicle. Then the papwer establishes a new energy double-layer consumption model, the upper layer takes the maximum consumption of new energy as the goal, and optimizes the electricity price as the independent variable, and transmits the optimized electricity price result to the lower layer; The lower layer aims at maximizing the profit of EV, and optimizes the number of EVs participating in the response as a variable, and returns the number of electric vehicles to the upper layer, and iterates circularly until the best result is obtained. Finally, taking the improved IEEE 33 power grid as case, the results mean that the method mentioned can greatly improve the new energy consumption.
