There are two kinds of compensation fashions for interruptible loads（IL）， namely low price compensation which is independent of power cut occurrence and high compensation which is performed only after actual power cut. The interruptible loads with low price（ILL） and the interruptible loads with high compensation（ILH） have been studied separately till now. Based on the viewpoint of risk management， this paper analyzes their different economic properties， points out that their coordination is beneficial to restrain market power and reduces the cost of reserve capacity and system stability. Taking the sum of the deterministic reduction of revenue resulting from ILL and the risk of compensating ILH as the objective function， the coordination models and optimization algorithms are proposed. Simulation results are presented to validate the method.
