摘要

提出了一种将同步发电机容量曲线（GCC）纳入最优潮流（OPF）约束的方法。在电力系统方程的支路流模型（BFM）中加入了qd变量下同步电机的稳态等效电路作为支路。采用二阶锥规划的方法，构造了具有GCC约束的基于bfm的OPF的高效凸松弛算法。这使得在OPF中包含非线性GCC方程，该方程随终端电压大小而变化，并包括转子显著性和定子电阻的影响。提供了数值验证和案例研究。

Optimal power flow with synchronous generator capability curves using the branch flow model

A method for incorporating synchronous generator capability curves (GCC) into the constraints of the optimal power flow (OPF) problem is proposed. The steady-state equivalent circuit of the synchronous machine in qd variables is added as a branch in the branch flow model (BFM) of the power system equations. Second-order cone programming is used to formulate a computationally efficient, convex relaxation of the BFM-based OPF with the GCC constraints. This enables the inclusion of nonlinear GCC equations, which vary with terminal voltage magnitude and include the impact of rotor saliency and stator resistance, in the OPF. Numerical verification and case studies are provided.
