Abstract

This paper considers a decentralised sliding mode load frequency control (LFC) for multi-area power system with uncertain time-varying parameters and delay. Since delays can exert a destabilizing effect on the overall system, it is necessary to maximize the delay bound in order to regularize the deviation in frequency and tie-line power. Robustness is improved by taking advantage of the system structure and uncertainty bounds. A sliding surface is designed, which guarantees the stability of the sliding motion and the stability of the sliding motion is analyzed based on Lyapunov-Razumikhin function which has a fast changing rate. A delay dependent decentralized sliding mode control is synthesized to drive the system to the sliding surface in finite time, and maintain a sliding motion afterward. The effectiveness of the proposed method is tested via a two-area interconnected power system.
