| 摘 要： | 提出一种在电力市场环境下考虑经济性约束的区域间可用输电能力的计算方法,建立了在系统每一运行点都能根据发电机组报价经济地分配其有功出力并限制各节点电价在某一可行范围内的数学模型,其目标函数是购电区域内负荷的增长量最大,约束条件为系统的安全性约束和经济性约束,更符合电力市场的实际情况.采用主从递阶决策求解数学模型,并利用非线性互补问题函数的近似半光滑牛顿算法处理底层优化问题所带来的不等式约束.以IEEE 30节点系统为例进行仿真并对计算结果予以分析,验证了所提出的方法的合理性.

| Abstract: | An algorithm for calculating available transfer capability(ATC)of power system in power market is presented.An optimal mathematical model considering the bidding of generators and the bus locational marginal price(LMP)is built.The objective function is to maximize the total active power consuming for load in sink area.The constraint is the system operation in a secure and economic way.A bi-level leader-follower decision-making measure is taken to solve the problem and semi-smooth Newton method is used to handle the large amount of inequality constraints which are imported by sub-optimal model.The numerical simulation results on IEEE 30-bus system demonstrate the validity of the proposed model. |
