Power generation control of restructured hybrid power system with FACTS and energy storage devices using optimal cascaded fractional-order controller

This work presents power generation control of a two-area hybrid restructured power system, initially integrated with renewable energy source (RES) and electric vehicle (EV). For further analysis, additional inclusion of FACTS and energy storage devices in the two-area hybrid restructured power system is to be analyzed for improved system dynamics. The hybrid restructured power system is a complex nonlinear system that brings light to the major problem of system dynamic control due to insufficient damping under varying loading circumstances. To solve this problem, a robust control approach with rapid acting controllable and storage devices are an immediate need for advanced power system. Motivated from the fact that cascaded fractional order controllers exhibit better performance in comparison to classical controllers, this article proposes an advanced cascaded fractional-order ID-fractional-order PD (cascaded FOID-FOPD) controller for system performance enhancement of hybrid restructured power system. The maiden application of satin bower bird optimizer technique to optimize the secondary controller gains is employed. The proposed controller's superiority is demonstrated by comparing the results to the other existing controllers. The impact of RES's generation and EVs on system dynamics for cascaded FOID-FOPD controller is also explored. Furthermore, the sensitivity analysis is done to reflect that optimized gains of cascaded FOID-FOPD controller are supportive enough for variations in RESs, load perturbations, capacity ratio, and disco participation matrix.
