Source-load Matching Degree Model of Natural Gas Distributed Energy Resource Aimed at High Comprehensive Energy Utilization Efficiency

Under the background of national requirement to further improve the comprehensive energy utilization efficiency, natural gas distributed energy system, as one of the efficient and clean energy utilization methods, has been incorporated into the national energy development strategy. However, the comprehensive energy utilization efficiency of key natural gas distributed energy enterprises in China can not meet the expectations. Based on the analysis of the energy efficiency of natural gas distributed energy, considering the objective existence of the load cultivation period, this paper establishes the source-load matching degree model and the source-load coordinated growth model, which have guiding significance for the scale of the construction of natural gas distributed energy units, and can help enterprises realize the efficient use of energy as soon as possible. And the validity of the model is verified by an example of a gas distributed energy project in a business district of Shanghai.
