摘　　要：在用户侧互动模式的基础上,提出了统一优化发电资源、用户侧互动资源的发用电一体化静态安全校核模式和模型,提高了系统重载情况下的N-1安全效益。针对N-1安全约束数量庞大和互动负荷的启动整数变量规模大的问题,提出了基于起作用互动负荷启动变量识别方法的主、子问题迭代算法,缩小了待优化空间,降低了混合整数规划模型的求解难度。通过新英格兰39节点系统验证了所提出的模型和算法的有效性。Based on the interaction mode on customer side,the generation and load integrated static security checking mode and model are developed.In this mode,both the generation and demand side interactive resources can be optimized at the same time to improve the security performance of system after N-1 contingency in the stressed cases.In response to computational difficulties brought by N-1 contingency constraints and interaction loads in large scale systems,a decomposition algorithm with identification method of active interaction integer variables is proposed,and the optimization space as well as the computation complexity of the mix-integer program problem can be effectively reduced by using this algorithm.The effectiveness of the model and algorithm proposed are demonstrated by numerical experiments on a New England 39-bus system.
