- Abstract:
- In view of the high permeability of new energy and the low coupling performance between electrity and gas systems in the IEGS, a robust optimization model of the integrated energy system of electricity and gas was proposed in this paper to improve the consumption of new energy, and strengthen, flexible conversion between electricity and gas energy. An electric-gas demand side load response model was established considering the price constraint coefficient, and using the second-order cone and McCormick method to convert the original mixed integer nonlinear model into a linear model. Scene screening rules was used to add the uncertainty of new energy, The IEEE 33-node power grid and the Belgian 20-node natural gas network interconnection system were modified, analyze and compare The model′s profit, electricity-to-gas capacity and power consumption rate, and the robustness of the system were analyzed and compared. It had a great advantage in nature and could better cope with the volatility of new energy.
