Problems solved by technology

At present, the multi-energy system mainly evaluates the operating economic cost and energy utilization efficiency of the multi-energy system under different needs through extreme scenarios such as abundant, abundant, dry, dry, and summer large, summer small, winter large, and winter small. and environmental benefits, etc., but this way of considering issues is too conservative. For multi-energy systems that pursue low-carbon, economic benefits and other aspects, the results obtained by evaluating and analyzing only under extreme events are not comprehensive, and it is difficult to obtain probabilistically close actual solution

Abstract

The invention discloses a multi-energy demand park comprehensive evaluation method and system oriented to low-carbon economic operation, and belongs to the technical field of comprehensive energy efficiency evaluation, wherein the method includes obtaining the demand and supply of electric energy, cold energy and heat energy in each period of the park's historical time length At the same time, obtain supply and demand cost data, construct a data evaluation set composed of all multi-energy data samples; perform screening and analysis based on the data evaluation set to obtain key data evaluation sets; Efficiency mathematical model and low-carbon loss mathematical model; based on the key data evaluation set, use the energy utilization efficiency mathematical model and low-carbon loss mathematical model to obtain a comprehensive evaluation value for the park's low-carbon multi-energy operation management platform. The invention can obtain a more comprehensive and reliable comprehensive evaluation result of the low-carbon multi-energy system of the park, and has more practical reference value.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy efficiency evaluation, in particular to a comprehensive evaluation method and system for multi-energy demand parks oriented to low-carbon economic operation. Background technique [0002] With the increasing depletion of traditional fossil energy and the continuous deterioration of the natural environment, how to use energy efficiently and cleanly has gradually become the focus of many scholars. The integrated energy (multi-energy) system involves the production, transfer and consumption of multiple energy sources such as electricity, heat, cooling, and gas. The multi-energy demand park can realize the mutual conversion of multiple energy sources and realize the complementary advantages of different energy sources, which is conducive to reducing the economic cost of park operation, improving energy utilization efficiency and environmental benefits. [0003] The multi-scene analysis t...
