Dynamic Simulation of Electric-gas Integrated Energy System with Variable Wind Power

The integrated energy system is an important part in the development of the energy field. It has attracted much attention because it can promote energy consumption and improve energy utilization efficiency. At present, the steady-state analysis of integrated energy systems has been deeply studied in economic dispatch and optimal operation, but the dynamic simulation of integrated energy systems still needs to be explored. In order to better study the influence between the various subsystems of the integrated energy system, this paper establishes a typical electric-gas integrated energy system simulation platform with wind uncertainty. The system is two-way coupled, and at the same time, uncertainty factors are introduced into the system through wind turbines, and the comprehensive energy system simulation is carried out through the multi-rate model established in this paper. The simulation results show that the proposed electric-gas energy system with wind uncertainty The simulation model can effectively reflect the interaction between sub-systems, and can reflect the impact of uncertainty on the integrated energy system, and can also improve the simulation efficiency to a certain extent.
