In order to guarantee capacity adequacy for the power system with a high penetration of renewable energy resources, it is necessary to establish a capacity market mechanism that is compatible with the energy market. From the perspective of investment decisionmaking, this paper analyzes the efficiency of capacity market mechanism in the power system with high proportion of renewable energy by studying supplier's investment behavior in capacity energy market with high integration of renewable energy. Firstly, a threelayer optimization model is established for the investment decision problem, including unit decisionmaking, capacity market and energy market model. Then since the model is difficult to solve directly, a phased loop iterative solution algorithm is proposed, being able to solve the problem with the capacity and energy market decoupled. Finally, based on the actual data of a certain provincial network, this paper uses the proposed method to compare the effects of energyonly market and capacityenergy market on capacity adequacy for the power system with a high proportion of renewable energy.
