A New Index for Voltage Instability of Power Systems

[[abstract]]In this paper, a new index is proposed as an indicator for voltage collapse of power system. The index can be easily calculated using simple information of power flow solution with little extra effort. More important is its pleasing quasi-linear characteristic to serve as an indicator of voltage instability. Some typical results for a practical power system are also presented for reference[[fileno]]2030146030026[[department]]電機工程學
