Research On Coupling Characteristics Of Information And Energy In Energy Internet

Energy Internet is the main trend of power system development.Energy Internet is a complex system of energy systems and information systems that are highly integrated.The fragmented research on energy and information is difficult to meet the requirements of energy Internet real-time control and reliability.Therefore,based on the mixed model of information physical fusion system and Synergy theory,this paper studies the coupling mechanism of energy flow and information flow by using the finite state machine principle,and establishes the coupling model of energy flow and information flow: finite state mixed model,and designs a hybrid computing method based on the synergistic mechanism of "source net load storage",and verifies the correctness of the finite state mixed model by simulating.Which provide a theoretical reference for further research on the integration of energy flow and information flow.The main contents of the thesis include the following aspects:(1)Research the characteristics,mathematical description of energy flow and information flow in the Energy InternetStudied the basic characteristics of energy flow and information flow in the Energy Internet,such as circulation and relevance,and established the hierarchical network structure of energy flow and information flow.On this basis,the calculation and analysis method of energy flow and the modeling and calculation method of information flow are studied.(2)Study the synergistic mechanism of energy Internet under information orientationBased on the theory of synergy,analyze the synergistic mechanism of "source net load storage",and emphasizes the important guiding role of information in the synergy process,which lay the theoretical foundation for the research of the coupling model between energy and information.(3)Establish a finite state mixed model of energy flow and information flow and conduct case analysisBased on the finite state machine theory and the reciprocal interaction of "energy flow-information flow-energy flow" in the Energy Internet,establish a finite state mixed model of energy flow and information flow;Design a hybrid algorithm of energy flow and information flow based on the coupling model of energy flow and information flow and the synergistic mechanism of "source net load storage" in the Energy Internet;And verify the correctness of the finite state mixed model and the hybrid algorithm of energy flow and information flow by the simulation of real time control of the Energy Internet subsystem.
