Robust load frequency control for networked power system with renewable energy via fractional‐order global sliding mode control

Owing to random load changes and transmission time delays in interconnected power systems with renewable energy, the frequency control scheme has become one of main methods keep stability security systems. To relieve communication burden increase network utilisation, an adaptive event-triggered is explored. Then, a new fractional-order global sliding mode comprising term surface adopted improve robustness control. The generates degree freedom more adjustable parameters performance. Furthermore, Markov theory applied modelling process better describe uncertainty external disturbances. stabilisation criteria for multi-area are put forward by employing improved Lyapunov function integral inequalities auxiliary functions. Finally, two simulation examples containing two-area system modified IEEE 39-bus New England test three wind farms presented investigate effectiveness proposed method.
