Active power regulation of hydro dominating energy system using IDD optimized FPA

In this paper an attempt is made to propose the different models of control and design such as integral derivative (ID), proportional integral derivative (PID) and integral double derivative (IDD) effectively optimized through flower pollination algorithm (FPA) for active power regulation of modern energy system having hydro dominating areas. At first, the performance of FPA-ID, FPA-PID and FPA-IDD founded LFC are evaluated for standard load change in one control area and their performance for system model is judged on the basis of inverse time multiplied absolute error (ITAE). The results obtained show the advancement of FPA-IDD over other designs for hydro dominating energy system. The performance of the control lacks in minimizing system overshoot, oscillations and settling time due to large responding time of hydro turbines. Hence, the collective operation of unified power flow control (UPFC) in series with tie-line and active power support from redox flow battery is installed in the hydro dominating energy system. The significant improvement in system results are obtained by installing the UPFC and RFB in system model. Further enhancement in the system results are achieved by recalculating the gains of IDD with the help of FPA with positive support from RFB and UPFC. The application results are obtained for standard load change and results show the effectiveness of the proposed technique for the hydro dominating energy system.
