Comprehensive energy system optimization operation method considering uncertainty and demand response

Abstract

The invention relates to a comprehensive energy system optimization operation method considering uncertainty and demand response, which comprises the following steps of: in a day-ahead optimization stage, establishing a comprehensive energy system day-ahead robust optimization operation model considering robust uncertainty and time shift type demand response according to day-ahead prediction dataand energy price fluctuation factors of various distributed energy sources and loads; in an intra-day optimization stage, according to intra-day prediction data of various distributed energy sources and loads and a system day-ahead optimization result, establishing an integrated energy system intra-day random optimization operation model considering random uncertainty and alternative demand response; enabling two models to form a comprehensive energy system day-ahead and day-ahead two-stage collaborative optimization operation model considering multiple uncertainty and comprehensive demand response, and calling a Gurobi solver through a Yalmip toolbox to carry out model solving. According to the invention, the complementary advantage of multiple energy sources can be effectively exerted, the comprehensive operation cost of a park is further reduced, and the economic, environment-friendly, flexible and efficient operation of the comprehensive energy system is realized.

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...
