Modified tangent vector‐based voltage stability constrained optimal power flow considering limit‐induced bifurcation
Autor: Yasuyuki Shirai, Shota Omi
Publikováno v: IET Generation, Transmission & Distribution. 14:4918-4926
A modified tangent vector (TV)-based voltage stability constrained optimal power flow method is proposed. The proposed method determines an optimal stable equilibrium point (SEP) satisfying the required voltage stability margin (VSM) considering limi

Comparative Study of Voltage Security Indices in Terms of Limit-Induced Bifurcation Effect
Autor: Yasuyuki Shirai, Shota Omi
Publikováno v: 2020 International Conference on Smart Grids and Energy Systems (SGES).
This paper compares six types of major voltage security indices (VSIs) in terms of limit-induced bifurcation (LIB) effect. The compared VSIs are the voltage collapse proximity indicator (VCPI), L-index, L mn -index, minimum singular value (MSV), tang

Evaluation of Switching Threshold in Hybrid Dispatch Method Based on Ramp-rate and Merit-order for Load Frequency Control
Autor: Tsujii Yuki, Shota Omi
Publikováno v: 2020 International Conference on Smart Grids and Energy Systems (SGES).
Power systems in Japan use a pro-rata (PR) method for load frequency control (LFC). The method dispatches output to all LFC target generators on the basis of the ramp-rate ratio. A merit-order (MO) dispatching method will be used after the balancing

Constrained state estimation with partial measurements in unobservable distribution network
Autor: Kenichiro Yamane, Masatoshi Kumagai, Masahiro Watanabe, Shota Omi
Publikováno v: 2015 IEEE Power & Energy Society General Meeting.
We developed a constrained state estimation method that clarifies the range of the feeder voltage in an unobservable distribution network in which the number of telemetric sensors is smaller than the number of state variables to be estimated. Instead
