The invention discloses a power supply configuration method for guaranteeing capacity adequacy based on selective options, and relates to the technical field of power
system optimal configuration. The method comprises the steps of constructing a
hybrid capacity adequacy mechanism, generating a market framework allowing a power generator and a user to autonomously select and participate according to the
hybrid capacity adequacy mechanism, and generating operation profit and option cashing data according to a contract distribution scheme, and based on the operation profit and the option cashing data, constructing a power generator residual model considering risk preference, wherein the power generator residual model generates a
residual value evaluation result. According to the method, the
hybrid capacity adequacy mechanism including a scarcity pricing mechanism and a reliability option mechanism is constructed, indication information is selected according to the generated market framework and mechanism, a power generator and a user are allowed to autonomously select to participate in the corresponding mechanism, the operation efficiency of the
energy market is optimized, the risk of a power
system is reduced, and the capacity adequacy is ensured.
