Abstract

Under the dual background of large-scale development of intermittent renewable energy and supply-side structural reform, technologies such as thermal power, power grid, demand-side response, and energy storage are facing the profound adjustment of industrial roles. It is the general trend to flexibly transform the resources of each side of the source network and participate in the power market. This chapter first introduces the transformation strategies of flexible resources such as thermal power peak adjustment transformation, power grid transformation, demand-side response, and energy storage construction and establishes the transformation cost and operation cost models of different flexible resources. Secondly, the mechanism of postplanning evaluation and coordination compensation of generalized flexible power supply is proposed, and the cooperative game model of income distribution of generalized flexible power supply is established. Then, the net income model of flexible resource planning and the benefit distribution model based on Shapley value are established, and the economic feasibility of flexible resource investment on each side is explained through case analysis. The research results show that flexible transformation of thermal power units is cost-effective and suitable for large-scale promotion and application. Large users of load-side flexibility resources can provide flexibility through peak regulation of their own power plants, and energy storage can be of large-scale promotion and application by 2030. Finally, the grid connection scenario with a high proportion of renewable energy is designed, which significantly reduces the carbon emissions and operation costs of a unit power supply.
