A Distributed Energy Management Method Based on Analytic Hierarchy Process and Membership Degree

Abstract

The present invention provides a distributed energy management method based on an analytic hierarchy process and a membership. According to the distributed energy management method, a target model is established through the analytic hierarchy process, membership evaluation is performed for each energy management index, a comprehensive optimization target function is established and corresponding constraint conditions are taken into consideration, so as to achieve a large-scale distributed cleaning energy access energy management function; power generation time period, active power output and reactive power output of each distributed power supply is quickly and effectively determined, thereby solving the problems of voltage control and economic optimization operation of various distributed power supplies during high penetration, and ensuring reliable operation of a power grid and achieving economic dispatch of distributed power generation, therefore, high social benefit and economic benefit can be achieved.

Description

technical field [0001] The invention relates to the field of distribution network automation, in particular to a distributed energy management method based on analytic hierarchy process and membership degree. Background technique [0002] Building a resource-saving and environment-friendly society is the common goal of all countries in the world. Energy conservation, consumption reduction and emission reduction have become one of the most important industrial themes at present. With the strong support of national policies, the utilization of various clean energy has become a social consensus, and the construction of distributed power generation such as photovoltaic power generation, wind power generation, and small hydropower has shown a trend of large-scale development. Because distributed power generation is often uncontrollable, and the ability of traditional power grids to withstand system fluctuations and changes is very limited, which largely limits the development of ...
