Abstract

The invention relates to a calculating method for design load of a natural gas distributed energy resource. The calculating method is characterized by comprising the following steps: obtaining energy consumption unit properties of different types of buildings and enterprises and users with different functions in an area, building or industrial park; calculating yearly energy loss curves of different energy consumption units; calculating user load delay curves by means of the demand side response principle with the combination of user requirements; adding the user load delay curves and the yearly energy loss curves together to obtain the yearly load distribution situations of the users, and making peak load serve as the design load of installation of a distributed energy resource station. By means of the calculating method for design load of the natural gas distributed energy resource, the conflict between energy supply and energy consumption and the conflict between energy supplying and energy saving can be effectively settled, and the problem that an installation scheme is not matched with the load due to large load is solved. By means of a distributed energy supplying system designed through the method, the optimal economical efficiency can be achieved whether from the view point of energy supply or from the view point of energy consumption.

Description

technical field [0001] The invention relates to a design method for a natural gas distributed energy supply system, in particular to a design load calculation method for natural gas distributed energy, and belongs to the technical field of natural gas distributed energy utilization. Background technique [0002] Natural gas distributed energy uses natural gas as fuel, realizes energy cascade utilization through combined cooling, heating, and electricity, and realizes energy supply in the nearest load center. Modern new energy supply mode. According to the scale of the system, it can be divided into regional distributed energy, building distributed energy and industrial distributed energy. [0003] Regional distributed energy is generally built in new urban areas, development zones, small towns, university towns and other areas with large building areas, many types of users, and large load demands, and the scale of unit assembly is relatively large. System design idea: first...
