摘　　要：基于机会约束规划,提出一种计及价格弹性负荷响应及风电不确定性的随机安全约束经济调度模型。模型考虑了输电断面潮流机会约束,并通过设置安全概率水平,控制输电断面潮流越限的概率。利用潮流灵敏度分析方法将分支潮流约束、输电断面潮流约束线性化,进而将输电断面潮流机会约束转化为常规约束,最终将所建随机优化模型转化为确定性二次规划模型,验证了所提模型及方法的有效性。Based on chance constrained programming,a stochastic security constrained economic dispatching model considering price elastic load response and wind power uncertainty is proposed.The chance-constrained transmission interface flow constraints should be considered to control the probability of transmission interface flow limit violation via the parameter of security probability.The branch power flow constraints and transmission interface flow constraints are linearized by power flow sensitivity analysis method,and then the chance-constrained transmission interface flow are transformed into conventional constraints.Finally,the stochastic optimization model is transformed into a deterministic quadratic programming model.The effectiveness of the proposed model and method is verfied.
