Coordination state determination method of a comprehensive energy system and related device

Abstract

The invention provides a coordination state determination method of a comprehensive energy system and a related device. The method comprises the steps of obtaining coupling parameter sets corresponding to all sub-energy systems; calculating system output vectors corresponding to all the coupling parameters according to the subsystem equation sets of all the sub-energy systems; calculating system coordination vectors corresponding to all the coupling parameters according to the coupling equation sets of all the sub-energy systems; and when the difference between the system output vector and thesystem coordination vector is smaller than a first preset convergence precision, determining that the comprehensive energy system is in a coordination state. According to the method, all parameter information of each sub-energy system does not need to be obtained, only coupling parameters among the sub-energy systems need to be obtained, and then the coordination state of the system is determinedaccording to the established sub-energy systems and the coupling equation, so that the information privacy of each sub-energy system is protected, and the complexity of the model can be reduced. Theefficiency of system simulation calculation is improved.

technical field [0001] The present invention relates to the field of multi-energy integrated systems, in particular to a method for determining the coordinated state of an integrated energy system and related devices. Background technique [0002] With the development of multiple energy networks, more and more attention has been paid to their energy efficiency. Therefore, it is of great significance to optimize the operation of multi-energy interconnection systems to alleviate energy demand. Due to the complex energy types of the multi-energy interconnection system, in order to realize the energy-saving and efficient operation of the multi-energy interconnection system, the effect of optimal control of a single energy source is not ideal, and the entire system must be considered and coordinated comprehensively.

Problems solved by technology

[0003] At present, related technologies use a unified modeling method to carry out coordinated simulation of integrated energy systems. This method requires the simultaneous integration of equations of different dimensions and time scales in each sub-energy system. In addition, due to the differences of different energy systems, the actual meaning of the unified physical quantity is not clear, and it is difficult to reflect the system characteristics of different sub-energy systems
