电动汽车最优充电模型及其近似求解方法
Optimum Electric Vehicle Charging Model and Its Approximate Solving Technique
摘要
Abstract
To optimize electric vehicle (EV) charging schedule and minimize charging costs, a formulation was presented on the basis of unit commitment (UC) results. An approximate algorithm based on minimum marginal cost was proposed to solve the formulation. Hourly marginal generation cost was calculated based on the UC results, and EVs were dispatched to be charged over the period with the minimum average marginal generation costs in priority. If present committed units failed to charge all EVs, extra units should be started for charging EVs in ascending order of unit average full-load cost (AFLC) for minimizing extra generation costs due to the newly started unit. The process described above was repeated until all EVs were scheduled. Simulation results validate the proposed methodology. The simulation results demonstrate that EV average charging cost increases with EV penetration level and the charging cost of fast charging mode is minimum.关键词
