Abstract

The invention provides a coalition game optimization operation method based on a user-side regional integrated energy system, which establishes a multi-objective function, calculates the energy inputquantity and price of the energy hub, converges to the optimal solution through multiple iterations of a double-layer model, and gives the basic conditions of the optimization problem. The invention also discloses a method for optimizing the energy input quantity and price of the energy hub. Each energy hub can trade with other hubs in the alliance and solve the Nash equilibrium solution by establishing the game model and utility function. The three-stage trading scheme of energy hub is designed, and the PSO algorithm is adopted to solve the maximum profit of each alliance, and the optimal operation strategy of the integrated energy system is obtained, and the optimal operation of the integrated energy system is realized. The method strengthens the cooperative relationship among energy hubs, can improve the flexibility of energy system operation, the utilization rate of energy cascade, reduce the waste of intermittent energy such as wind and light waste, and lighten the pressure on theenergy supplier on the user load side.

Description

technical field [0001] The invention belongs to the technical field of energy optimization, and in particular relates to an alliance game optimization operation method based on a user-side regional comprehensive energy system. Background technique [0002] Recently, with the successive implementation of energy industry policies, the level of energy demand is gradually increasing. Traditional energy systems, such as power systems, natural gas systems, and thermal systems, are mostly planned and operated independently, lacking coordination and cooperation with each other, which is not conducive to the economical and efficient operation of the energy supply system. With the development of the energy Internet, electricity, The coupling and internal dependence of natural gas, thermal energy and other energy sources are significantly enhanced, and the trend of multi-energy coordinated operation is becoming more and more obvious. The integrated energy system is of great significanc...
