Regret avoidance-based user-level comprehensive energy system optimization method

Abstract

The invention relates to a regret avoidance-based user-level comprehensive energy system optimization method. According to the method, a regret avoidance method is adopted to optimize a traditional extended planning model taking optimal system expected cost as a target. A natural gas price change scene of a user-level comprehensive energy system and operation characteristics of energy coupling equipment and energy storage equipment in the natural gas price change scene are deeply analyzed; based on a system comprehensive total cost net present value in a planning period, an extended planning model taking minimum system comprehensive regret value as an objective function and taking system operation and equipment output characteristics as constraint conditions is constructed, the uncertaintyof natural gas price is fully considered by the model, the obtained planning result is the optimal construction scheme of the system; and compared with a traditional method, the method has the advantages that the result, accuracy and rationality are improved.

Description

technical field [0001] The invention relates to the field of comprehensive energy system planning, in particular to an energy system optimization method. Background technique [0002] The user-level comprehensive energy system is an intensive area of ​​energy consumption, mainly including specific forms such as parks, commercial areas, residential communities, hospitals, and universities, and has a large demand for electricity, gas, cold, heat, coal, crude oil, etc. and reliable energy supply The characteristics of high performance requirements are the specific manifestations of the construction and implementation of comprehensive energy systems. At present, the dispatching and control of various energy systems on the user side belong to different departments, and the planning, construction, operation, and maintenance of the internal equipment of the energy system are carried out independently, which leads to the low energy utilization rate and low investment in the energy s...
