摘要：
In order to promote the user's flexible load resources to participate in the demand response effectively, load aggregators can be employed to arrange load resources to participate in the grid dispatch. By dividing the user's loads into several categories, a hierarchical dispatch model is proposed that consists of the power grid company, load aggregators, and residential users. In day-ahead bidding, the game model is formulated based on maximizing load aggregators' profit, load aggregators' bidding behavior is analyzed with non-cooperative game, and the existence of Nash equilibrium is also given mathematically. In the real-time scheduling, for promoting load aggregators' profit without affecting users' comfortableness, the minimum error between real-time scheduling and bidding results is taken as a goal to schedule users' loads with constraints on three kinds of loads in physical characteristics. A case study validates the effectiveness of the proposed hierarchical dispatch model on demand response of flexible load. And simulation results show that the power network company, load aggregators, and residential users can all benefit simultaneously. © 2017 Automation of Electric Power Systems Press.
