Abstract

The invention discloses a multi-microgrid integrated energy system optimization scheduling method considering demand side response and shared energy storage, and the method comprises the steps: adding a shared energy storage system into a multi-microgrid integrated energy system containing electric energy interaction, and forming a multi-microgrid integrated energy system model containing shared energy storage and electric power interaction; adding autonomous response behaviors of users in micro-grids to a multi-micro-grid integrated energy system model containing shared energy storage and electric power interaction, and considering the influence of the autonomous response behaviors of the user side on the multi-micro-grid integrated energy system model containing shared energy storage and electric power interaction; and proposing a two-stage optimization model based on a master-slave-cooperative game, solving the whole optimization process and the optimal capacity of the shared energy storage device, and distributing the profit of the contribution degree of the alliance microgrid. The user demand side response is added into the multi-microgrid comprehensive energy system model containing shared energy storage and electric energy interaction, and the effects of peak load shifting and microgrid and user cost saving are achieved; and a win-win situation between the micro-grid and the user is realized.

Description

technical field [0001] The invention relates to the technical field of multi-microgrid optimal dispatching, in particular to an optimal dispatching method for a multi-microgrid integrated energy system that takes demand-side response and shared energy storage into consideration. Background technique [0002] In recent years, problems such as energy shortage and environmental pollution have become increasingly serious. How to develop clean and efficient energy supply methods and how to achieve sustainable energy development has attracted widespread attention at home and abroad. The multi-microgrid integrated energy system realizes cascade utilization of energy by giving full play to the complementary characteristics of different energy sources, which is an important direction for future energy development. When the same power distribution area is connected to multiple microgrids, a multi-microgrid system will be formed. When there is power interaction between each microgrid ...

Problems solved by technology

In the multi-micro-grid integrated energy system, each micro-grid belongs to different subjects and each micro-grid user has an independent response behavior, and there is a complex interaction of interests among them, which brings new challenges to the operation and regulation of the multi-micro-grid integrated energy system. big influence

[0003] In addition, the proportion of wind and solar output in the microgrid is increasing. Due to the intermittent and uncertain characteristics of wind and wind power generation, it leads to serious abandonment of wind and light.
