Micro-energy network capacity optimization planning method based on economy-environment and energy dynamic pricing double-layer game

Abstract

The invention discloses a micro-energy network capacity optimization planning method based on an economy-environment and energy dynamic pricing double-layer game. The method comprises the following steps: designing a framework of the economy-environment and energy dynamic pricing double-layer game micro-energy network capacity optimization planning method, establishing an upper-layer environment-economy evolutionary game planning model, establishing a lower-layer energy dynamic pricing strategy master-slave game model, establishing a multi-energy conversion coupling hub model and the like. Theconflict relation between economic benefits and environmental benefits in the planning problem can be considered, meanwhile, the energy price dynamic characteristics are considered, the conflict benefits between a micro-energy network operator and a user are balanced, and the planning efficiency and economy are improved. The planning total cost can be effectively reduced, the user load peak-valley difference is balanced, the energy utilization efficiency is improved, meanwhile, emission of greenhouse gas CO2 and air pollutant NOx is reduced, and the environmental value is achieved. The methodhas the advantages of scientificity, reasonability, high applicability, good effect and the like.

Description

technical field [0001] The present invention relates to the field of micro energy grid (Micro Energy Grid, MEG) capacity optimization planning, which is a micro energy grid capacity optimization planning method based on economy-environment and energy dynamic pricing double-layer game, which is applied to the micro energy grid distribution of multi-energy coupling Joint planning of distributed power supply (Distribution Generation, DG), multi-energy conversion components, energy storage system (ESS) and thermal storage system (TSS). Background technique [0002] With the increase of global energy demand and the pressure brought by environmental protection demand, the energy pattern is constantly developing from traditional fossil energy to a new energy pattern of balanced development and complementary utilization of renewable energy. As a small integrated energy supply system integrating energy interconnection, conversion, coupling, storage and other functions, micro energy n...
