Abstract

The invention discloses an interconnected microgrid layered energy scheduling method based on a high-dimensional target optimization decision. The method comprises the following steps: after a hierarchical energy scheduling framework of the heterogeneous multi-microgrid system is established, establishing a mathematical matrix for describing an interconnection relationship of a plurality of microgrids in the heterogeneous multi-microgrid system, and determining a power interaction cost calculation mode among the interconnected microgrids; optimizing the energy scheduling of the heterogeneous multi-microgrid system according to the power interaction cost calculation mode and the high-dimensional target optimization method; and performing energy scheduling on the heterogeneous multi-microgrid system according to an optimization result. The technical scheme provided by the invention aims to solve the problem that the interests of a part of micro-grids are damaged due to the fact that theoptimal scheduling of energy is carried out by taking the lowest overall operation cost of a multi-micro-grid system as a target and the interest competition relationship among the micro-grids for reducing the respective operation cost is ignored.

Description

technical field [0001] The invention relates to the field of interconnected heterogeneous microgrid energy scheduling, in particular to a hierarchical energy scheduling method for interconnected microgrids based on high-dimensional target optimization decision-making. Background technique [0002] In order to improve the power supply reliability of a single microgrid (hereinafter referred to as microgrid) and the ability to absorb renewable energy, it is a feasible solution to connect multiple microgrids to form a multi-microgrid system. The scale of energy dispatching by the multi-microgrid system is also increasing. In the scheduling process, the microgrid has the right to independently choose whether to participate in the multi-microgrid scheduling. It participates in the scheduling of the multi-microgrid system, usually to improve its own stability and reduce its own operating costs. In the existing multi-microgrid In the grid energy scheduling strategy, the optimal sch...
