Abstract

The invention discloses an energy simulation and optimal scheduling method, system and equipment of an integrated energy system, and the method comprises the steps: determining a building database in a region, determining a region energy supply form and an energy equipment type according to the building database in the region, and determining an energy price parameter; calculating the annual hourly load demands of the users in the region for cold, heat and electricityaccording to the building database in the region, and constructing a comprehensive energy system according to the geographic position and load characteristics of the region; establishing an energy conversion model of each energy supply device and a corresponding constraint condition according to a user load demand, and establishing an energy simulation model of the integrated energy system; performing equipment annual operation condition optimization, energy storage scheduling operation optimization and energy release scheduling operation optimization on the system; and further solving the energy simulation scheduling model based on a particle swarm algorithm by taking the operation cost, the initial investment and the recovery period as objective functions, and finally obtaining the optimal operation mode and the shortest recovery period of the initial investment.

Description

technical field [0001] The invention relates to the technical field of integrated energy systems, in particular to a method, system and equipment for energy simulation and optimal scheduling of an integrated energy system. Background technique [0002] The design of the regional comprehensive energy supply scheme is a systematic project, which involves preliminary preparatory work such as regional land use planning, load forecasting analysis, energy supply system design, equipment selection, equipment capacity allocation, and use scheduling; but the existing In the design and research of regional comprehensive energy planning and scheduling methods, empirical values ​​and fixed values ​​are mostly used in equipment selection and equipment efficiency. Unreasonable equipment selection leads to equipment capacity allocation that is too large or too small, resulting in insufficient energy supply in the region Or the problem of excessive investment; the scheduling between the ene...
