Decentralized sliding mode control technique based power system stabilizer (PSS) for multimachine power system

Robust multimachine power systems control via high order sliding modes

“…Moreover, the structure of the current switched power converters of synchronous generators are suited for the application of SM approach since the control variables produced by SM control law switch fast between extreme limits. Examples of classical SM controllers for single machine and multimachine power systems can be found in [24,25]. However, these controllers were designed for reduced order plants only and their implementation to higher order plant would provoke finite-frequency, finite-amplitude oscillations (chattering), since unmodeled fast electrical dynamics could be excited [23].…”

Fractional‐order lead‐lag compensator‐based multi‐band power system stabiliser design using a hybrid dynamic GA‐PSO algorithm

“…Secondly, in the design of PSSs, many robust control techniques have been used, such as variable structure control [10], H ∞ optimal control [11], periodic output feedback [12], pole assignment technique [13], quantitative feedback theory [14], sliding mode control [15]. However, the power system is considered to be a highly non-linear and large-scale multi-input multi-output dynamical system with numerous variables.…”

Reconfigurable Fault-tolerant PSS and FACTS Controllers

“…The problem of PSS design has been addressed in the literature using many techniques, including, but not limited to, thyristor-controlled series capacitor reference reactance ı rotor angle of the generator relative stability of the system d desired relative stability ! rotor speed of the generator root locus and sensitivity analysis, adaptive control, robust control, pole placement, H 1 design, and variable structure control [3][4][5][6][7][8]. The powerful optimization tool of linear matrix inequalities is also used to enhance PSS robustness through state and output feedback [9][10][11].…”
