Transient energy calculation method and suppression measure of integrated energy system

The main methods to analyze the transient stability of integrated energy system (IES) are time domain simulation method and direct method. Because the physical properties of different energy systems in IES are very different, and the interaction between different energy systems is very complex, the time domain simulation method is difficult to apply. The direct method can be used to analyze system stability based on transient energy, and the calculation method of transient energy is its core. Based on this, this article proposes a transient energy calculation method for IES, first, this article analyzes the energy conversion process of the IES and puts forward the corresponding transient energy calculation method; second, in order to verify the correctness of the transient energy calculation method, the time domain simulation model of the IES is established; Finally, a transient energy suppression method is proposed. Three simulation cases are designed, and the simulation results show the accuracy of the transient energy calculation method and the effectiveness of the suppression measure.
