Performance of coordinated FACTS and energy storage devices in combined multiarea ALFC and AVR system
This paper emphasizes the impact of a coordinated flexible AC transmission system (FACTS) and energy storage devices in the combined automatic load frequency control and automatic voltage regulator model of a multiarea system having reheat thermal, wind, solar thermal, and diesel units in each area. The generation rate constraints and the governor dead band for the thermal plant are considered. A fractional integral derivative controller with filter (FOIDF) is proposed for this model, and the lightning search algorithm is implemented to optimize the controller parameters. The comparative analysis of FOIDF with integer order controllers shows the superiority of the former to others. The system performance with different area capacity ratios demonstrates the significant effect of the same on the system dynamics. Analyses reflect the satisfactory performance of the proposed renewable integrated system with a drastic change in step load perturbation. Investigation of the integration of FACTS devices like a thyristor controlled series capacitor, a static synchronous series compensator, and an interline power flow controller (IPFC) indicates that the inclusion of FACTS devices improves the system dynamics and IPFC is better among these. Analysis of the effect of energy storage devices such as capacitive energy storage (CES) and superconducting magnetic energy storage (SMES) in coordination with IPFC reveals that energy storage devices along with FACTS enhance the system responses and IPFC-SMES is much better than IPFC-CES. The investigation indicates that IPFC inbetween Area1 and Area3 and SMES in Area1 are the optimal locations. Sensitivity analysis reflects that the proposed controller parameters are not required to be optimized again for changing system conditions.
