Local PV sensitivity (PVS) is adopted as the indicator of voltage stability. Compared with traditional methods, the proposed method only requires local voltage magnitude, active power flow measurements and the parameters of transmission lines connected to local node. The proposed method will check the operation status of each transmission line first and thus formulate the calculation expression of the voltage stability index. Then we will calculate the PVS accordingly. And we have analyzed the uncertainty of PVS led by the measurement errors. Simulation studies using IEEE 39 nodes system will be introduced and used to demonstrate the effectiveness of the proposed method.}, number={3}, journal={Periodica Polytechnica Electrical Engineering and Computer Science}, author={Ge, Huaichang and E, Zhijun and Guo, Qinglai and Gong, Chenghu and Sun, Hongbin and Wang, Bin}, year={2015}, pages={99–103} }
