Optimization Operation of Multi-energy Complementary System based on Interval Model

It has become an inevitable choice for the development of the energy industry to build a distributed multienergy flow co-generation system. It forms a multi-energy complementary co-generation system by coupling cold, heat, gas and electricity through energy production, transmission, conversion, supply, storage, energy using equipment and protection, measurement and control equipment. This paper is based on interval theory to describe the uncertainties of cold, hot and electric load, distributed energy output and operating conditions, using the transfer matrix to construct the relationship between the input and output of multiple energy sources, and the coupling modeling of the multi-energy complementary system. Considering the impact environment, economy and other factors, multi-objective optimization is carried out for the system. The interval linear programming based on affine operation is used to solve the model, which can effectively solve the problem that the interval operation is too conservative, and simulated verify the validity and rationality of the model and method.
