Abstract

The invention discloses a stochastic production simulation method and system of an integrated energy system. The method includes: obtaining source data; processing electric load data to obtain net electric time-series load data; determining an equivalent continuous electric load curve and an equivalent continuous steam load curve; determine the initial steam volume function of the integrated energy system; obtain the equivalent steam volume function; determine the steam output of the unit; determine the power generation of the unit; determine the natural gas consumption of the unit; The continuous electric load curve determines the system's expected shortfall and electric shortfall expectations. The above method in the present invention can estimate the steam production and power generation of different units in the integrated energy system and purchase electricity from the grid, estimate the cost of the integrated energy system, simulate the scheduling of the integrated energy system in the industrial park, and realize the reduction through optimal scheduling. Reduce system operating costs and improve energy efficiency.

Description

technical field [0001] The invention relates to the field of energy assessment, in particular to a stochastic production simulation method and system for an integrated energy system. Background technique [0002] Integrated energy system (Integrated Energy System, IES), as a basic component of Energy Internet, can realize effective scheduling and efficient utilization of different energy sources in a region (such as a city, community or industrial park, etc.). The comprehensive energy system is a complex energy system based on the load, covering various production capacity / energy consuming subjects, and involving the production, transfer and utilization of various energy sources such as electricity, cold and heat. Its load demand is large, the load characteristics are complex, and the reliability of power supply is high. [0003] Probabilistic production simulation (PPS) is under the future load curve, considering the random outage of the unit and the random fluctuation of ...
