Abstract

This work focuses on a Load-Frequency Control (LFC) problem of two-area interconnected multi-source power systems. It is a new kind of network, consisting of numerous sophisticated inter-weavings: generation rate constraints, temporal delay, and Superconducting Magnetic Energy Storage (SMES), as well as Unified Power Flow Controller (UPFC), which can be used to more accurately reflect the operating states in real life. To enhance the network frequency stability, a new type of Sliding Mode Controller (SMC) is developed, in which the parameters of the sliding surface are optimized from a hybrid PSO-GWO-ABC algorithm. The developed approach leverages the benefits of PSO, GWO, and ABC to optimally yield the explicit solution and thus improve control performance. By primary indicators like frequency difference of two zones, power oscillations on interconnecting lines, overshoot, and stabilization time, the performance of the controller is inspected under step response and random load perturbations. MATLAB/Simulink package was used to simulate the proposed PSO-GWO-ABC-SMC controller, showing enhanced quickness and stability with reduced oscillation and stabilization times relative to other optimization solutions. These findings show the effectiveness of the newly proposed LFC methodology in increasing frequency stability in the interconnected power grid.

Keywords
