随着大规模风电并网的高度一体化，天然气网与电网之间的相互影响越来越大，建立了含风电并网的天然气网与电网一体化系统的短期检修策略。情景模拟代表风力发电波动。为了克服天然气系统非线性、非凸模型带来的不利影响，采用分段线性逼近方法将原非线性模型转化为混合整数线性模型。为了保证输电线路和输气管道的功率平衡和燃气平衡，采用大M公式化方法构造不等式约束。整个问题被建模为一个混合整数线性规划问题。对一个6节点4节点气网系统的数值试验表明了该模型的有效性。
With the growing interaction between natural gas grids and electric power grids associated with the high integration of large-scale wind generation, this paper establishes short-term maintenance strategies for integrated natural gas and electric grids with wind energy integration. Scenarios are simulated to represent wind power volatility. To overcome the adversities caused by the nonlinear and non-convex models of natural gas systems, a piecewise linear approximation approach is used to transform the original nonlinear models into mixed integer linear models. To ensure power balance and gas balance for transmission lines and gas pipelines, a big-M formulation method is used to construct inequalities constraints. The entire problem is modeled as a mixed integer linear programming problem. Numerical tests on a 6-bus system with a 4-node gas gird show the effectiveness of the proposed model.
