A Study of Capacity Value Characterization of the Stochastic Fluctuation Characteristics of New Energy Sources

The stochastic fluctuation characteristics of new energy have a great impact on the construction of electricity market. In this study, the correlation between the stochastic fluctuation characteristics of new energy and the system flexibility performance is established to realize the boundary decision of capacity market clearing model considering the system flexibility demand, and the capacity market clearing model is formed. The capacity market clearing model and the capacity price formation method considering the credible capacity of new energy are developed to realize the investment incentive for capacity supply resources. The simulation results show that the proposed method can more effectively reflect the value difference of different resources, guarantee the reasonable returns of market members, and stimulate the market parties to take the initiative to improve the level of new energy consumption in the power grid.
