Multi-energy demand statistical method based on user energy demand type

Abstract

The invention discloses a multi-energy demand statistical method based on a user energy demand type. The method is applicable to the multi-energy comprehensive utilization system with the park or user as a unit. The designed method performs classification based on energy flow, conversion and demand type in the energy conversion module and the energy output module in the multi-energy system, as the basis for analysis, selects the proper energy conversion method from the equal value method, the equivalent calorific value method and the equivalent electrical method, performs statistical calculation of multi-type energy in the energy supply module, and further comprehensively calculates and obtains the sum of the user multi-energy demand. The method can effectively overcome the defects and the logic conflict in the single energy conversion method, thereby enabling the energy statistics to be more fair and reasonable.

Description

technical field [0001] The invention relates to the technical fields of energy statistics and energy saving, in particular to a multi-energy demand statistics method based on user energy demand types. Background technique [0002] Energy is the basis for the survival and development of human beings, and the lifeblood of the national economy. How to ensure the sustainable supply of energy in human society while reducing environmental pollution in the process of energy consumption is a hot spot of common concern for all countries in the world today. Strengthen the comprehensive utilization of multi-energy , to explore new ways of energy utilization and improve energy efficiency. [0003] In a multi-energy integrated system, due to the different types of energy, whether it is statistically calculating the total energy consumption of the system or evaluating energy utilization efficiency from different dimensions, such as energy consumption per unit of GDP, energy consumption pe...

The equivalent value method is based on the energy balance sheet of my country's energy accounting, according to the average coal consumption of electric power generation into standard coal, and the actual corresponding primary energy is considered when evaluating the secondary energy. There will be logical contradictions in the energy flow process of conversion or multi-type energy output; the equivalent calorific value method uses the heat contained in the energy as an indicator to directly calculate the "quantity" of its energy, regardless of the level of energy quality. The difference between the grade of energy and the ability to do work, only looking at the amount of heat contained in the energy will also lead to fallacies in the evaluation of energy conservation; the equivalent electric method, in order to consider that electric energy is the highest grade energy, combined with the work potential of various types of energy, unified Converted into the maximum electric energy conversion potential, this method considers the grade and work of energy, which is more scientific, but in the actual energy system, part of the energy flow is directly used by low-grade energy without conversion into high-grade electric energy, so the overall accounting statistics There is also a lack of accuracy in
