Optimal Bidding Strategy of a Electric Vehicle Aggregator in Electricity Market
摘要
Abstract
ABSTRACT:Withrapid development of electricity market and electric vehicle (EV),EVaggregator can help EV usersto decrease charging costs by bidding in electricity market. Bidding model of an aggregatorparticipating in day-ahead and real-time electricity market was proposed with objective of minimizing charging costs while satisfying EVs' flexible demand.The aggregator was assumed to potentially influence pricesinday-ahead and real-time market.Bidding strategy of the aggregator was formulated as a bi-level model,withthe upper level model representingcharging cost minimization of the aggregator, whereas the lower level model representing market clearing providingmarket price and energy for the upper level model.Bids of other market participants and EV driving pattern werenotknown to the aggregator in advance. They were seen as fuzzy variables and random variables. Uncertainty theory was used to solve thisrandom-fuzzy programming problem. A numerical example was used to illustrate feasibility of the proposed method.The results indicate that the bidding strategycandecrease EVs’charging costs effectively.关键词
