Transient stability constrained optimal power flow using independent dynamic simulation

Providing Transient Stability by Excitation System Response Improvement Methods through Long Term Contracts

“…Transient Stability Constrained Optimal Power Flow (TSC-OPF) is a preventive control action which is utilized to optimize operation point of generators in order to provide transient stability of the system. This topic was discussed in several articles [2][3][4][5][6]. In [2][3][4], rotor angle equations were considered as a transient stability constraint in optimal power ow.…”

“…In [4], authors modelled transient stability as an objective function besides active power cost and, then, solved this multi-objective optimization by Nondominated Sorting Genetic Algorithm II (NSGA-II). In [5,6], time domain simulation was performed to analyse transient stability of the system and simulation results were utilized in optimal power ow. In [5], simulation results determined critical and non-critical generators of the system.…”

“…In that method, active powers of the critical generators were decreased to enhance the transient stability of the system. In [6], results of time domain simulation were converted into a single equation as a transient stability constraint in OPF. Active power of generators, machine angle, magnitude and angle of buses voltage, and other optimization variables were used to determine the initial operation point to increase transient stability of the system.…”

Advanced application of transient stability constrained‐optimal power flow to a transmission system including an HVDC‐LCC link

“…Transient stability constrained-optimal power flow (TSC-OPF) techniques include an economic objective and static and dynamic constraints in the same optimisation problem [1][2][3]. Therefore TSC-OPF is an adequate tool for creating a transparent mechanism for calculating optimal economic operation when the system is restricted by steady-state and stability constraints.…”

“…), as in [2,[15][16][17][18][19][20][21]. In these studies, generators are classified as critical or non-critical machines and the single-machine equivalent (SIME) method is generally used to obtain the most simplified equivalent system.…”
