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.

Description

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. [0003] At present, related technologies use a unified modeling method to carry out coordinated simulation of integrated energy systems. This method requires the si...
