The remarkable growth of power electronics- interfaced renewable generations in the electric power grid has the potential to pronounce the effect of frequency disturbances such as inter-area oscillations. These low-frequency disturbances reduce transmission lines capacity, and at worst even damage the power grid infrastructures. In this paper, we propose a novel control algorithm to eliminate inter-area oscillations modes based on local measurements of frequency and the system's global average frequency. The performance of the proposed solution is investigated on different multi-machine test systems with classic and detailed electromechanical dynamic models through modal analysis and time-domain simulations. The modal analysis results indicate that all the inter-area modes are damped for all test cases. Time-domain simulations also demonstrate that the proposed control not only takes the system to near-zero inter-area oscillations but also improves other power system stability measures such as transient stability and frequency nadir. |
