摘要:

电力批发市场常采用电力系统约束的线性近似。由于未考虑不等式约束,使用交流潮流进行可行性后处理可能违反无功功率、电压幅值或热极限的边界。目前仍需一种简化的分析方法,在遵守变量边界的同时保证交流可行性。本文提出一种增强型交流潮流实现方式,通过额外两种母线类型(PQV和P)解决传统方法中的电压边界违反问题。该方法牺牲发电机的电压设定点,以固定负荷母线的电压,从而在网络中转移自由度。在IEEE 14母线、57母线和300母线测试案例上的结果表明,母线类型切换可减少整体网络违反,并帮助找到可行的电力系统设定点。

英文摘要:

Wholesale power markets often use linear approximations of power system constraints. Because it does not consider inequality constraints, using AC power flow for feasibility post-processing can violate bounds on reactive power, voltage magnitudes, or thermal limits. There remains a need for a streamlined analytical approach that can guarantee AC feasibility while adhering to variable bounds. This paper suggests an augmented implementation of AC power flow that uses an additional two bus types (PQV and P) to help resolve voltage bound violations present in the traditional approach. The proposed method sacrifices the voltage setpoint at a generator in exchange for fixing the voltage at a load bus, thereby moving a degree of freedom around the network. Results on the IEEE 14-bus, 57-bus, and 300-bus test cases demonstrate how switching bus types can reduce overall network violations and help find feasible power system setpoints.
