Multi-energy system coordination control method based on Markov model

Abstract

The invention relates to the technical field of multi-energy system coordination control methods, in particular to a multi-energy system coordination control method based on a Markov model. The multi-energy system coordination control method comprises the steps of: modeling an electricity, gas and heat network of the multi-energy system; establishing a compressor equipment model; establishing a cogeneration system model; establishing a renewable energy power generation system model; establishing a multi-energy load model; establishing a Markov model of the multi-energy system; and verifying the simulation example based on a Markov model-based multi-energy coordination control method. The Markov model is established by analyzing the change characteristics of the output and load requirementsof the renewable energy sources, the coordination interaction among the source, the load and the storage is achieved by installing the energy storage system, the heat storage device can achieve electric heating decoupling, the electricity storage device can smooth the output fluctuation of the renewable energy sources, and the balance of the supply and the demand of the energy sources is achievedby effectively controlling the absorbed energy and the released energy of the energy storage system, so that the safe and efficient operation of the whole multi-energy system is ensured.

Description

technical field [0001] The invention relates to the technical field of multi-energy system coordination control methods, in particular to a Markov model-based multi-energy system coordination control method. Background technique [0002] With the rapid decline of fossil raw material reserves and people's increasing attention to environmental issues, in order to alleviate the problems of "abandoning wind and solar", comprehensive utilization of multiple complementary energy sources has become one of the effective ways to solve the above problems. The integrated energy system can effectively integrate and utilize multiple resources, improve the energy efficiency of the system, and solve problems such as new energy consumption at the same time. Therefore, the integrated energy system has been extensively studied, and the traditional model of "power consumption determines power generation" is gradually change. At present, most of the research on the integrated energy system is ...
