Evaluation method suitable for micro-energy grid planning and design

Abstract

The invention relates to an evaluation method suitable for micro energy network planning and design. An index setting part sets construction conditions, technical effects and economic and social benefits. The index calculation part refines the index setting part into a resource condition, a site condition, a policy condition and a technical condition; Technical effect indexes are refined into energy interactivity, safety and reliability, energy supply quality and energy utilization efficiency; Economic and social benefit indexes are refined into investment income, environmental protection andenergy conservation; Dividing each index by the index scores, and calculating to obtain scores of each index in the effect type, the cost type, the interval type and the qualitative type; Carrying outweighted average on the index scores to obtain a comprehensive score value of a certain micro energy network planning design scheme; And finally, obtaining a comprehensive score value of each micro-energy grid planning and designing scheme, comparing the comprehensive score values of each micro-energy grid planning and designing scheme, giving an evaluation conclusion, and giving an optimizationsuggestion of the planning and designing scheme in combination with the development status, the development demand and the construction target of the micro-energy grid.

Description

technical field [0001] The invention relates to an evaluation method suitable for micro-energy network planning and design, in particular to an evaluation method for micro-energy network planning and design scheme construction conditions, technical results, economic and social benefits, and the like. Background technique [0002] In recent years, with the rapid development of multi-energy coupling, energy Internet and integrated energy systems, technologies related to micro-energy grids for parks and buildings have also made great progress. The micro-energy network is composed of distributed energy, energy storage, energy conversion devices, monitoring and protection devices, and loads. It integrates multiple types of energy, has self-control and self-energy management functions, and is directly oriented to small-scale energy interconnection for end users. The system has the characteristics of diverse sources and loads, high energy integration, and some micro-energy grids ca...

Problems solved by technology

[0005] At present, there have been many studies on the evaluation methods of distribution network, gas network, and heat network planning schemes, and a wide range of engineering applications have been carried out. However, for micro energy grids, electricity, gas, heat, Multiple forms of energy such as cold are highly integrated, and there are obvious characteristics of complementary and interactive effects between different forms of energy. The evaluation method of a single form of energy cannot accurately reflect the implementation effect under the environment of multi-energy integration, and cannot be used for micro-energy network planning.
