Problems solved by technology

At present, there have been a series of research results on the joint cost pricing problem of multi-energy flow networks coupled with electricity and heat, but the researches all try to decouple the electricity price and heat price on the production side, and then participate in the bidding in their respective energy markets. This decoupling process will have simplifications and errors, which deviate from the actual situation

Abstract

The invention relates to an electric-thermal coupling multi-energy flow network node energy price calculation method, and belongs to the field of the energy market of a comprehensive energy system. According to the method, the coupling relationship of electricity price and heat price in an electric-thermal coupling network is considered, the present situation that joint cost pricing of a thermal-electric joint supply set can only be calculated in a decoupling way can be broken through, and the market interaction mechanism of the electric-thermal coupling system is restored so that the accuracy of marginal cost calculation can be enhanced in comparison with the existing method of respective pricing of the power supply and heat supply systems. Meanwhile, node energy price acts as one of real-time price and compensates the blank of real-time heat price in the heat supply network so that a certain thought is provided for congestion management and network loss allocation of the heat supply network.

Description

Technical field [0001] The invention relates to an energy price calculation method for an electric-thermal coupling multi-energy flow network node, which belongs to the energy market field in a comprehensive energy system. Background technique [0002] With the increasingly severe energy supply, the problems in the use of renewable energy have become prominent. In order to optimize the efficiency of energy use, building a multi-energy flow system has become a new method. In a multi-energy flow system, various forms of energy, such as electricity, gas, cooling, heat, etc., are coupled and interacted in production, transmission, consumption and other links to improve the operating economy of the entire system. In a typical multi-energy flow network, the combined heat and power system has developed the fastest. At present, there have been a series of research results on the joint cost pricing of the electricity-heat coupled multi-energy flow network, but the research attempts to de...
