Abstract: Demand response can effectively make better load curve and system reliability.A method for translational load to participate in demand response is proposed based on the block model.For the case of the short duration load segment has to bear the high cost of power generation,an optimization model of load segment combination is proposed.In the model,the load agent integrates the load as a long duration segment to get cheaper purchase.On this basis,a market clearing model is proposed.To solve the problem of electricity purchase cost allocation,the bilateral Shapley value（BSV）method of game cooperation is used.The method is applied to an actual case.The results show that the integration of load can reduce the cost of generation,get a cheaper buy,and achieve a win-win situation for both power producers and users.
