The invention discloses a multi-energy supply system load prediction method, which is characterized by comprising the following steps of 1 analyzing load requirements of the multi-energy supply systemand coupling relationships among the load requirements; 2 respectively predicting the electric load and the gas load of the multi-energy supply system based on the time sequence model to obtain an electric load initial predicted value and a gas load initial predicted value; 3 determining a gas-electricity exchange influence factor based on the relationship between the electric load and the gas load; 4 weighting each pneumoelectric exchange influence factor by adopting a linear weighting method, and calculating a conversion coefficient of gas-to-electricity conversion; and 5 obtaining a load prediction result of the multi-energy supply system. On one hand, the coupling relation between various loads is comprehensively considered to predict the power and gas loads of the multi-energy supplysystem; and on the other hand, a basis can be effectively provided for a decision maker to realize optimal utilization of resources and improve the energy utilization rate.
Description
technical field [0001] The invention belongs to the technical field of forecasting of energy supply systems, and in particular relates to a load forecasting method of a multi-energy supply system. Background technique [0002] With the development of advanced science, people's demand for energy is increasing. At the same time, traditional fossil energy is becoming increasingly exhausted, and issues such as energy security and environmental protection have attracted much attention. However, the existing energy conversion efficiency of cold, heat, and electricity is low. , non-centralized distribution, and high cost of use are common, making energy and the environment the main bottleneck restricting the sustainable development of the national economy. Energy is the basic condition for the rational, effective operation and continuous progress of human society and economy. How to reduce environmental pollution while ensuring sustainable energy supply is a topic of concern to all...
