Method and system for planning output power of energy consumption equipment

Abstract

The invention relates to the field of energy utilization, and provides a method and system for planning output power of energy consumption equipment, and the method comprises the steps: obtaining the historical energy consumption, historical output power and user load of energy consumption equipment, and employing a pre-built energy conversion model, a comprehensive energy utilization efficiency model and an energy consumption equipment comprehensive energy model to obtain the historical heat production efficiency, the historical power generation efficiency, the historical energy efficiency coefficient and the comprehensive energy utilization efficiency of the energy consumption equipment and the output power of any energy consumption equipment with the maximum comprehensive energy utilization efficiency. According to the embodiment of the invention, the method comprehensively considers that the energy consumed by the user terminal energy consumption equipment is cold, hot, electric and gas energy, and obtains the output power of any energy consumption equipment with the highest energy utilization rate by combining the mutual conversion characteristics among the cold, hot, electric and gas energy while meeting the cold, hot, electric and gas loads of a user. The defect that only single energy is considered in the prior art is overcome.

Description

technical field [0001] The present application relates to the field of energy utilization, in particular to a method and system for planning output power of energy-consuming equipment. Background technique [0002] With the continuous advancement of industrialization, the level of energy consumption is also increasing. Under the pressure of the contradiction between supply and demand between the rapidly growing energy demand and the decreasing fossil energy, energy production and consumption patterns need to be changed, and the pursuit of efficient use of energy is crucial. important. [0003] At present, the main available energy sources include: cold, heat, electricity and gas. These energies are utilized by the user's energy-consuming equipment, and the energy-consuming equipment provides users with cold energy, heat energy and electric energy. The terminal of these four energy sources, the energy-consuming equipment includes: cogeneration units, gas boilers, gas turbine...

AI Technical Summary

Problems solved by technology

[0005] In order to improve the utilization rate of available energy, in the prior art, the output power of energy equipment is planned to meet the user load demand, for example: for To meet the heat load demand of users, it is necessary to plan the output power of the energy-consuming equipment that provides heat energy, so that the energy-consuming equipment that provides heat energy can provide appropriate output power to improve the utilization rate of heat energy. However, this planning method only considers a single Energy, heating, cooling, electricity, these four energy sources are not considered comprehensively, so the energy utilization rate is not high
