Abstract
Under the background of demand response(DR)program,if load aggregators(LAs)are allowed to share the demand side adjustment capability,specifically,those with higher unit adjustment cost can purchase the adjustment services from those with lower unit cost,then those with lower costs can increase the revenue from sharing services,and those with higher costs can reduce the adjustment costs,thus achieving a win-win situation.Therefore,a demand side adjustment capability sharing mode is proposed.Firstly,the demand side adjustment cost of all LAs are evaluated,including the load adjustment cost and the energy storage system(ESS)adjustment cost.Then,a non-cooperative DR optimization model is established to estimate the optimal response,DR reward revenue and potential adjustment capability.Since the essence of sharing is to redistribute the adjustment cost,a demand side adjustment cost optimization model based on cooperative game is established to solve the demand side adjustment costs and responses of each LA after sharing,and calculate the settlement costs among LAs.The case study shows that the profits of LAs from DR program have been improved after participating in the sharing market.关键词
