Layered and partitioned optimization operation method for comprehensive energy system based on master-slave game

Abstract

The invention discloses a layered and partitioned optimization operation method for a comprehensive energy system based on a master-slave game. The method comprises the steps of establishing a master-slave game layered and partitioned architecture of a multi-park comprehensive energy system; based on a master-slave game layered and partitioned framework of the multi-park comprehensive energy system, establishing a game main body optimization model of the multi-park comprehensive energy system and a game slave body optimization model of the multi-park comprehensive energy system; combining a game subject optimization model of the multi-park comprehensive energy system and a game slave optimization model of the multi-park comprehensive energy system to jointly form a master-slave game double-layer optimization operation model of the multi-park comprehensive energy system; and solving the master-slave game double-layer optimization operation model of the multi-park comprehensive energy system by adopting a chaos adaptive particle swarm optimization algorithm in combination with a mixed integer linear programming method. The complementary advantage of cold, heat, electricity and gas energy sources is effectively exerted, the comprehensive operation cost of the system is further reduced, and economic, flexible, cooperative and optimized operation of the multi-park comprehensive energy system is achieved.

Description

technical field [0001] The invention relates to an optimal operation method of an integrated energy system. In particular, it relates to a hierarchical partition optimization operation method of an integrated energy system based on a master-slave game. Background technique [0002] With the increasing depletion of global fossil energy and the gradual aggravation of environmental pollution, renewable energy such as wind energy, solar energy, and geothermal energy have received more and more attention. The world's energy structure is facing great challenges. As a natural extension of the microgrid, the integrated energy system integrates multiple types of distributed energy and traditional energy sources such as cooling, heating, electricity, and gas, and can realize cascaded and efficient utilization of energy. It has become an important means of green, efficient and sustainable energy utilization today. [0003] A variety of energy devices are integrated in the integrated e...

Problems solved by technology

Most of the existing literature focuses on a single energy building or park micro-grid. There are few studies on the collaborative optimization operation of multiple comprehensive energy parks in the region, and less consideration is given to the multi-type energy interaction support between different parks.
