Method and system for calculating energy efficiency of rural micro-energy network

Abstract

The embodiment of the invention provides a method and system for calculating the energy efficiency of a rural micro energy grid. The method comprises: obtaining a rural micro-energy grid energy supply model, and obtaining a rural micro-energy grid planning evaluation index and a rural micro-energy grid evaluation method based on the rural micro-energy grid energy supply model; and obtaining a rural micro-energy network evaluation result based on the rural micro-energy network planning evaluation index and the rural micro-energy network evaluation method. According to the embodiment of the invention, a rural micro-energy network planning evaluation system is established by adopting three levels of calculation indexes, and the planning value of each planning scheme of the rural micro-energy network is obtained by using a method of combining an entropy weight method and expert evaluation so as to judge the advantages and disadvantages of each planning scheme. The rural micro-energy network planning evaluation indexes all have definite physical meanings and calculation methods, have the characteristics of high practicability and operability, and can effectively and comprehensively perform comprehensive evaluation and calculation on the reliability, environmental protection property, economical efficiency, benefit and other aspects of the rural micro-energy network planning scheme.

Description

technical field [0001] The invention relates to the technical field of micro-energy grids, in particular to a method and system for calculating the energy efficiency of rural micro-energy grids. Background technique [0002] With the depletion of fossil energy such as coal and petroleum and the increasing environmental pollution, how to realize the stable application of renewable energy, improve the comprehensive utilization rate of energy, reduce environmental pollution, and ensure the safe supply of energy has become an important research for countries all over the world. topic. Therefore, the concept of integrated energy network came into being, which consists of energy supply network (power grid, natural gas network and cooling and heating network), energy exchange link (combined cooling, heating and power supply unit, air source heat pump, etc.), energy storage link (battery , cooling and heating energy storage devices, etc.) and a large number of terminal integrated e...
