Distributed Robust Adaptive Frequency Control of Power Systems with Dynamic Loads
For power system operators, it provides a distributed control method to maintain frequency stability under uncertain loads, though the approach is incremental.
The paper proposes distributed internal model controllers for frequency control in multi-machine power systems with uncertain dynamic loads, guaranteeing stability via Lyapunov analysis and demonstrating effectiveness on the IEEE 68-bus test system.
This paper investigates the frequency control of multi-machine power systems subject to uncertain and dynamic net loads. We propose distributed internal model controllers that coordinate synchronous generators and demand response to tackle the unpredictable nature of net loads. Frequency stability is formally guaranteed via Lyapunov analysis. Numerical simulations on the IEEE 68-bus test system demonstrate the effectiveness of the controllers.
