Abstract

The invention discloses a multi-rate calculation method for a dynamic model of an integrated energy network. The method includes, firstly, establishing a dynamic model of an integrated energy system based on the attributes of each energy subsystem; then, based on the dynamic model, according to each energy subsystem The time scale of the system is simulated and calculated for each energy subsystem. This calculation method avoids the situation that the converged subsystem continues iterative calculation due to the interface interaction with the maximum simulation step size when a certain subsystem does not converge in the traditional hybrid simulation, and improves the calculation efficiency.

Description

technical field [0001] The invention belongs to the technical field of energy simulation, in particular to a multi-rate calculation method for a dynamic model of an integrated energy network. Background technique [0002] In the integrated energy system, due to the large dynamic response time span of various energy system equipment and the obvious difference in dynamic response characteristics, the dynamic characteristics of the system are more complicated, and the simulation of the integrated energy system with the same step length cannot meet the requirements of convergence and accuracy . [0003] The existing comprehensive energy system composed of power system, thermal system and fuel pipeline network, etc., among which, the power system has a more detailed equipment dynamic model and mature system dynamic simulation means; thermal system, fuel pipeline network and other non-electric energy systems, Dynamic simulation has a certain model and algorithm research foundatio...
