Abstract

Based on the existing time-of-use electricity price pricing scheme of Beijing, a real-time pricing scheme for electric vehicle charging is proposed in this paper to perform load shifting by adjusting the hourly-changed charging price. A two-stage model of determining electric vehicle charging price is proposed. In the first stage, the charging load of the next day is predicted according to statistical probabilities. Together with the prediction of the base load pattern, the charging price of each hour is then optimized accordingly as a reference for the next day. In the second stage, the exact charging price is set ahead of each hour based on the power demand in previous hours and the desired load curve. The model is first built and then solved using the CPLEX software and MATLAB programming. The simulation result shows that the peak load as well as the peak-valley load difference is reduced. The charging cost of customers is also expected to be diminished.
