Abstract

The invention discloses a regional integrated energy system optimization scheduling method, system and equipment. The method comprises the steps: introducing carbon transaction cost into a distributedequipment probability model, and constructing a power system optimization scheduling model considering spatial-temporal correlation; and based on a point estimation method and a space change method,solving the power system optimization scheduling model considering the spatial-temporal correlation to obtain output data of a comprehensive energy system, and performing scheduling optimization on the comprehensive energy system according to the output data. According to the invention, the carbon transaction cost is introduced to construct the power system optimization scheduling model considering the spatial-temporal correlation, the model is solved based on a point estimation method, a correlation coefficient matrix of standard normal distribution is converted into an original space throughinverse transformation to carry out deterministic calculation, the optimization problem of output randomness and correlation of the model is solved, and the scheduling potential of distributed equipment is exerted by utilizing the spatial-temporal complementarity of distributed power supplies in a wide area.

Description

technical field [0001] The invention relates to the field of optimal scheduling of integrated energy systems, in particular to a method, system and equipment for optimal scheduling of regional integrated energy systems. Background technique [0002] With the technological progress of the power industry, the increasing consumption of fossil resources and people's concern for the environment around the world, distributed power generation, as an effective supplement to traditional energy generation, has been more and more widely used. Distributed power usually refers to small modularized, decentralized, high-efficiency and reliable power generation units distributed near users with a power generation of tens of kilowatts to tens of megawatts. Common distributed power sources mainly include wind power generation, solar power generation, fuel cells, micro gas turbines, cogeneration units, etc. At present, a lot of research work has been carried out on the coordination and contro...
