【摘要】 输电能力是所有电力市场的参与者进行交易活动所必需的重要信息。文中提出了一种考虑常见 FACTS装置 (如 UPFC,TCPS,TCSC等 )的最大输电能力计算模型 ,在模型中考虑了电压水平、线路和设备过负荷等静态安全性约束条件 ,以及由于潮流方程解的鞍点分叉导致的电压稳定性约束条件。在算法上选用逐次线性化优化方法 ,并对每一个线性化子问题采用新算法——预测校正原始对偶对数障碍内点法求解。算例计算结果不仅说明了不同的 FACTS装置和安装位置对电网的输电能力有不同程度的影响 ,同时也表明了文中的模型和算法是有效的 ,具有一定的应用价值。更多还原

【Abstract】 The transfer capability is important for all the partners participating in the electric power transaction activities. This paper put forward a m odel for calculating the transfer capability which incorporates comm only used FACTS devices such as thyristor controlled series com pensator TCSC ,thyristor controlled phase shifter TCPS and unified power flow controllers UPFC .This model considers constraints such as voltage limits,branch power limits and voltage stability limits resulting from saddle node bifurcation of power flow equations. The problem here is solved by a predictor- corrector prim al- dual log- barrier PCPDL B method as a sequence of linearized sub- problem . Numerical test results show that FACTS devices and their installation locations have different effects on the transfer capability of the networks. Meanwhile,the results also prove that the model and algorithm are effective and of application values.更多还原
