STABILITY EVALUATION AND STATIC CONTROL METHOD FOR ELECTRICITY-HEAT-GAS INTEGRATED ENERGY SYSTEM

摘要

The present invention provides a stability evaluation and static control method of an electricity-heat-gas integrated energy system, and relates to the technical field of integrated energy. The method comprises the following steps of S1, modeling the electricity-heat-gas integrated energy system by a method combining data driving with mechanism driving; S2, screening the abnormal data and performing association identification; S3, performing stability evaluation method, wherein focus on solving the power flow of energy flow, and calculating the reduction quantities and the wind abandoning quantities of the loads, whether the energy flow is out of limit is used as a criterion, and a calculate equation for stability indexes is defined, so that a system stability evaluation criteria comparison table is given; and S4, performing static control. One strategy is used for solving the problem independently by subsystems, and the other strategy is used for solving the problem through multisystem coordination. According to the integrated energy system model established through combination of data driving with mechanism driving, predication of the load change condition and double identification of abnormal data of the system are realized, and the system can be accurately and reasonably subjected to stability evaluation and static control.
