To achieve optimal charging schedules, many studies have assumed that the PEV aggregator can exercise full direct load control. This paper proposes a mathematical program with equilibrium constraints for the PEV aggregator's decision making in different electricity markets, using indirect load control by determining optimal retail prices for the PEV. This permits the final customers to decide on their charging schedule by decentralized profit optimization. These decisions respect a potential discomfort that may arise when PEV users have to deviate from their preferred charging schedule as well as include the option of using alternative sources of energy. In a small case study of 3 vehicle clusters and 6 time periods the model's functionality is highlighted. Results indicate that under reasonable competition on the retail market, the PEV aggregator's profitability depends on providing the right price signals to the final customers, such that the most efficient charging schedule response is achieved.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121133280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed framework, vehicles are modeled as agents actively placing bids to purchase electricity in the spot market. Their bids depend on status variables which represent the urgency to charge. To ensure scalability, the bids of large numbers of PEVs are aggregated. Then, they are cleared with the remaining market supply and demand bids. In this paper we focus on determining the optimal bidding strategies of individual PEVs, taking into account the uncertainty related to market bids and to driving behavior. For this purpose, we formulate a learning process based on Q-learning, where each vehicle adapts its bidding strategy over time according to the market outcomes. We perform simulations with historical market bid data, and realistic vehicle driving patterns from an agent-based transport simulation. Results show that the costs of charging can be significantly reduced compared with an uncontrolled charging approach. Moreover, we compare the results with those of a centralized aggregator-based approach, where an aggregator directly manages charging and purchases electricity on behalf of PEVs on the spot market. We show that the results of the decentralized market-based control approach are just slightly higher than those of the centralized approach.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123771385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
