Abstract

The invention discloses a day-ahead collaborative optimization operation method of a regional integrated energy system. Firstly, the structure of the regional integrated energy system is analyzed andthe optimization range is determined. Secondly, based on the optimized range, the input and output characteristics of the energy production and conversion equipment and the transmission, distributionand use characteristics of the cold, heat and electricity energy in the multi-energy supply system are extracted, Then, an operation optimization model is constructed to minimize the operating cost ofthe regional multi-energy supply system. Finally, the system parameters, equipment parameters and load forecasting data are inputted, and the objective function is optimized, and the day-ahead collaborative optimization operation scheme of the regional integrated energy system is obtained. The invention improves the energy use efficiency and reduces the operation cost of the regional integrated energy system by coordinating and optimizing the operation of the multi-energy sources of cooling, heating and electricity in the regional integrated energy system.

Description

technical field [0001] The invention belongs to the technical field of optimized operation of an integrated energy system, and in particular relates to a method for synergistically optimized operation of a regional integrated energy system with economical efficiency as the optimization target. technical background [0002] With the increasing contradiction between the depletion of traditional fossil energy and the large demand for energy, issues such as energy supply reliability and environmental friendliness have received extensive attention. Energy and the environment have become the main bottleneck restricting the sustainable development of the national economy. The physical characteristics of the power system, thermal system and gas system are highly complementary, giving full play to the complementary advantages of each energy supply system can improve the comprehensive utilization efficiency of energy, promote the consumption of renewable energy, and provide users with...
