Problems solved by technology

At present, most researches on regional integrated energy systems at home and abroad are carried out under the framework of steady-state (time-invariant) assumptions, which can only reflect the steady-state conditions when the system reaches a certain equilibrium state.

Abstract

The invention discloses a dynamic simulation system and method for an integrated energy system. The integrated energy system comprises a power network, a heat supply network and connectable coupling equipment connected between the power network and the heat supply network. The electric power network and the heat supply network are mutually coupled through the connectable coupling equipment, and the electricity and heat utilization requirements of users are met at the same time. According to the method, on the basis of a bonding graph theory, dynamic characteristics of the regional integrated energy system are combined, and a bonding graph model of main basic elements of the regional integrated energy system is established. According to the method, a state equation of the regional integrated energy system is further constructed and solved, a dynamic simulation result of the regional integrated energy system can be obtained by utilizing an output equation, the dynamic characteristics of the regional integrated energy system are fully considered, numerical simulation and analysis are performed on a certain actual regional integrated energy source through an example, and the dynamic simulation result of the regional integrated energy system is obtained. And an effective theoretical basis is provided for safe and stable operation of the regional comprehensive energy system.

Description

technical field [0001] The invention relates to a dynamic simulation system and method of an integrated energy system, belonging to the technical field of integrated energy control. Background technique [0002] In the context of Energy Internet, the dynamic simulation of integrated energy system has become one of the solutions for countries to deal with energy problems. The integrated energy system can organically coordinate different energy systems, complete the mutual coupling, transformation and distribution of various types of energy, and realize energy ladder utilization. However, there are many challenges in the modeling and simulation of integrated energy systems, such as mutual coupling between different energy sources and large differences in inertia of different energy systems. [0003] Therefore, how to take into account the complex dynamic characteristics of different energy systems and establish an effective integrated energy system model for dynamic simulatio...
