Speed-droop Governor based on Sliding Mode Control (SMC) for Generators in Interconnected Power System

This paper presents the design of two primary frequency regulation schemes with speed-droop characteristics by using Sliding Mode Control (SMC) as an alternative to standard governor. The mathematical development of speed-droop governors based on SMC is presented and then their implementation is developed in a three-area power system. Performance of proposed controllers are evaluated under simulation, first without secondary regulation and then with it. Simulation results demonstrate the feasibility of the SMC-based primary frequency control and its performance indexes demonstrate the effectiveness of it.
