Multi-energy microgrid planning method for integrated energy system

Abstract

The invention discloses a multi-energy microgrid planning method for an integrated energy system. The method comprises the following steps: 1), designing a multi-energy microgrid basic architecture: interconnecting and integrating a traditional power system, a natural gas system and a thermodynamic system in a region; 2), constructing a multi-energy microgrid multi-objective collaborative planningmodel taking minimum system planning operation cost, minimum wind and light curtailment and minimum pollutant emission as objective functions, and realizing collaborative optimization planning of a plurality of energy subsystems; and 3), improving the traditional multi-objective genetic algorithm by using a Tent mapping improved chaotic optimization algorithm to form a chaotic optimization multi-objective genetic algorithm, and solving the model by using the chaotic optimization multi-objective genetic algorithm on the basis of verifying the robustness of the algorithm. According to the method, the system cost is effectively reduced while the multi-element load requirement is met, the resource allocation efficiency is remarkably improved, a forward effect is achieved on safe operation ofa large power grid system, and the method has a good application prospect.

AI Technical Summary

Problems solved by technology

[0003] At present, my country's research on integrated energy systems is basically still at the level of concept, system form and operation mode exploration, and there is less research on system planning methods

However, directly researching the planning and operation of the integrated energy system under the target form is not only not feasible at the level of modeling and solving, but it is also difficult to directly and effectively verify and apply relevant results at this stage.
