Method and device for determining general energy efficiency datum line of integrated energy system

Abstract

The invention relates to a method and a device for determining a general energy efficiency datum line of an integrated energy system. The method comprises the following steps: acquiring energy consumption and supply data of the integrated energy system in each sampling period and energy consumption and supply data of each subsystem in the integrated energy system in each sampling period; determining the energy efficiency of the comprehensive energy system in each sampling period by utilizing the energy consumption and supply data of the comprehensive energy system; determining the energy efficiency of each subsystem in the comprehensive energy system in each sampling period by utilizing the energy consumption and supply data of each subsystem in the comprehensive energy system; determininga general energy efficiency reference line of the comprehensive energy system based on the energy efficiency of the comprehensive energy system in each sampling period and the energy efficiency of each subsystem in the comprehensive energy system in each sampling period; the reference line is convenient for operators of the comprehensive energy system to perform benchmarking in the operation stage of the system and judge the energy efficiency level of the system in actual operation so as to improve the scheduling strategy.

Description

technical field [0001] The invention relates to the field of planning, design and scheduling optimization of regional energy systems, in particular to a method and device for determining a general energy efficiency baseline of an integrated energy system. Background technique [0002] At present, cities and towns are the carriers for coping with global warming and low-carbon development. They bear about 80% of the world's energy consumption, and greenhouse emissions also account for more than 80% of the global total. Therefore, the rational use and efficient use of urban energy resources Planning is key to addressing current energy and climate issues. [0003] However, in the process of rational utilization of urban energy resources and efficient planning, how to effectively measure the energy efficiency of each planning scheme is the key to solving the problem. Under the existing planning methods, economy is often the first planning index rather than Neglecting the compreh...

[0003] However, in the process of rational utilization of urban energy resources and efficient planning, how to effectively measure the energy efficiency of each planning scheme is the key to solving the problem. Under the existing planning methods, economy is often the first planning index rather than Ignore the overall energy efficiency performance of the system, that is, establish a system planning model with the total investment cost or operation and maintenance cost as the objective function

However, because it is impossible to ensure that the energy efficiency of a single device in the planning and design is consistent with the actual operation, it is necessary to solve the problem of determining the energy efficiency baseline of the comprehensive energy system in the planning and design stage from the perspective of the energy utilization rate of the comprehensive energy system
