Problems solved by technology

[0006] However, the modern power distribution system has complex energy coupling relationships and massive data information. The traditional hierarchical coordination optimization method cannot take into account the collaborative optimization of the energy supply side and the energy consumption side at the same time, which has certain limitations. The traditional CHP system operates in a single mode. , the game models related to energy transactions only focus on energy transactions, and the research on dynamic game methods for multiple energy transactions in power distribution systems is still a vacancy. The traditional KKT conditions need to be formulated when used to solve the model, which is difficult to apply to the game model, and Does not protect user privacy
