Based on the time process characteristic and economic efficiency characteristic of the civilian active load system's interaction demand response，a behavior analysis mode of active load's interaction response is proposed.A demand response operation-decision model is developed to maximize the profits of users and power industries，even with social welfare taken into account.Then an evaluation index system is proposed that can represent and identify the physical features of the interactive response behavior among usersenergy demands，electricity demands and the cooperation between distributed renewable energy and grid by the decoupling response behaviors between users' energy consuming load and electric load.Finally，the effectiveness of the model and index system proposed is verified by an analysis of the residential and commercial quarters active load system's response behavior in the heavy space cold load grid，respectively，the active load system consisting of cold storage air conditioning and distributed wind generation in the heavy air-conditioning cold load grid.
