Coordinated tuning of controller-parameters using symbiotic organisms search algorithm for frequency regulation of multi-area wind integrated power system

Application of a New Fusion of Flower Pollinated With Pathfinder Algorithm for AGC of Multi-Source Interconnected Power System

“…When the power produced falls below the required quantity, the generator units begin to decrease in speed and frequency. The discrepancy between the power generated and the required load demand over a long time leads to an alteration in the system's nominal frequency and voltage profile [4], [5]. To tackle the effect of changes in the system's frequency and tie-line loading, the automatic generation control (AGC) control scheme is employed to regulate the deviations in active power and active power output of each generation unit within the control zone, as well as to maintain the frequency and provide interchange with other fields [6].…”

“…The findings showed a better performance than with other approaches, namely GA-based PID and PSO-based PID controller under the same condition to ensure a fair comparison. Singh [5], presented an optimal gain of a filtered PID (PID ) controller using symbiotic organisms search (SOS) algorithm. To investigate the output of a controller, some case studies of various load disruptions were performed in both areas with varying wind penetration levels.…”

Design of a dual‐layered tilt fuzzy control structure for interconnected power system integrated with DFIG

“…Various approaches have been proposed by researchers to alleviate such complications and were found to be adequate for certain operational cases. [6][7][8][9][10][11] Predominantly, these techniques aim to extend frequency support to IPS by VSWTs through various schemes such as the inclusion of inertial control, power reserve control, pitch control, and speed control. 8 Further, the impact of wind penetration level has also been studied with and without inertial support in ref.…”

“…8 Further, the impact of wind penetration level has also been studied with and without inertial support in ref. [10] and it was found that the dynamic performance of IPS could be significantly improved by the inclusion of frequency support in the system. Ramtharn et al presented a two-loop control scheme for frequency support, one control loop acts on frequency deviation, while the other acts on the rate of change of frequency deviation with DFIG based WPP and claim improvement in system performance.…”

“…The NRTPU and DFIG based WPP system parameters have been adapted from refs. [6,10,36] and are presented in Appendix 1. Both control areas, shown in Figure 1, are equipped with their generating unit, speed governing mechanism, and turbine unit along with DFIG based WPP.…”
