Integrated energy system optimization operation method considering uncertainty and demand response

Abstract

An integrated energy system optimization operation method considering uncertainty and demand response: In the day-ahead optimization stage, based on the day-ahead forecast data of various distributed energy sources and loads, and energy price fluctuation factors, a robust uncertainty and A day-ahead robust optimization operation model of a time-shifted demand response integrated energy system; in the intraday optimization stage, based on the intraday forecast data of various distributed energy sources and loads, the system day-ahead optimization results, and the establishment of stochastic uncertainty and alternative demand The intraday stochastic optimization operation model of the integrated energy system for response; the two models constitute the two-stage cooperative optimization operation model of the integrated energy system taking into account multiple uncertainties and integrated demand response, and the Gurobi solver is invoked through the Yalmip toolbox Model solver. The invention can effectively bring into play the advantages of mutual assistance among various energy sources, further reduce the comprehensive operation cost of the park, and realize the economical, environment-friendly, flexible and efficient operation of the comprehensive energy system.

Description

technical field [0001] The invention relates to an optimal operation method of an integrated energy system. In particular, it relates to a comprehensive energy system optimization operation method that takes into account uncertainty and demand response. Background technique [0002] With the increasing energy depletion crisis and environmental pollution problems, the existing energy production and consumption patterns are difficult to meet the needs of the current rapid economic and social development. The limitations of various energy sources and the diversity of human demand for terminal energy determine the It is difficult for any kind of energy to undertake the heavy responsibility of energy transformation alone. In this context, the Energy Internet came into being. As an important development direction of the Energy Internet, the integrated energy system is an important means to improve the efficiency of social energy use and promote the large-scale utilization of rene...
