Bi-Level Optimizing Power Purchase Strategies for Load Aggregators Considering Electricity Price Risks
摘要
Abstract
With the continuous growth of the proportion of renewable energy and the increasingly significant peak-valley difference in the load center grid,the development and utilization of distributed resources has become a research hotspot,which promotes the emergence of new entities such as producers and consumers and load aggregators.In view of the different optimization objectives of each stakeholder,this paper constructed a bi-level optimization model with the load aggregator as the electricity seller to participate in the electricity market.Firstly,the demand response mechanism of producers was introduced to form the master-slave game framework,and Karush-Kuhn tucker(KKT)conditions were used to integrate the lower level goals and constraints of the two-level model to the upper level to achieve a unified solution.Secondly,the conditional value at risk(CVaR)method was introduced to quantify the risk impact of electricity price uncertainty on the power purchasing strategy of load aggregators.Finally,the empirical example analysis shows that the mechanism can effectively encourage the user side adjustable resources to participate in the flexibility adjustment of the system,and promote the win-win cooperation pattern between the load aggregator and the producer and consumer.关键词
