The quotation of thermal power units in the spot electric energy market is usually based on short-term marginal costs,which makes it difficult for some marginal units to recover the investment costs,thus the reasonable income and investment enthusiasm of thermal power units cannot be guaranteed.A clearing model of medium and long-term electric energy market and an electricity decomposition method of medium and long-term difference contract are established,and a clearing model of spot electric energy mar-ket including new power system entities such as new energy stations and energy storages is established.Based on the long-term simulation results of electric energy market,a capacity compensation mechanism is designed considering the investment cost recovery condition and clearing probability of marginal unit.The effectiveness of the proposed mechanism is verified by the example simulative results of a modified IEEE 10-machine 39-bus system.
