“…Singh and Solanki [15] have discussed comparative performance of three different methods, namely IRP theory, SRF theory and adaline based to derive reference currents. Recent control approaches based on adaptive repetitive control [16], predictive current control [17], Wiener filter [18], Gauss-Newton-based controller [19], and improved equal current approach [20] have also been developed by several researchers.…”

“…However, in the secondary distribution system (voltages less than 2.3 kV), usage of MLI for DSTATCOM applications is not a cost-effective option. This is because, it requires more number of switches and higher control complexity compared to the two-level inverter [16,17]. Finally, FL-DSTATCOM is suitable for both 3P3W and 3P4W systems, however, it requires two additional switches compared to three-leg and TPSC DSTATCOM.…”

“…Therefore, in order to overcome the drawbacks of above control schemes and to explore the capabilities of ES-1, this paper discusses and proposes a modified instantaneous symmetrical component algorithm (ISCA)-based control to operate ES-1 as an APF and to explore its functional capabilities. Among the different reference current generation algorithm [19][20][21][22][23][24][25][26], ISCA is used due to its simple formulation and ability to work under any source and load conditions [26]. Further, the switching sequence of inverter is generated using hysteresis current tracking controller utilising the reference currents generated by modified ISCA to nullify currentbased issues and simultaneously achieving voltage regulation using single multifunctional control.…”

Recently, a new technology called as electric spring (ES) is used for suppressing the voltage fluctuation and stabilising the smart grid. To address the harmonic issue in case of non-linear critical load and for achieving voltage regulation in presence of disturbance source, this paper suggests ES-1 topology and proposes modified instantaneous symmetrical component algorithm (ISCA). The reference currents extracted using proposed ISCA with hysteresis current control (HCC) operates ES in active power filter (APF) mode. This improved algorithm can mitigate the harmonics in the source currents effectively, facilitate to set the source-side power factor (PF) to the desired value (unity) and simultaneously perform the task of critical load voltage regulation using single multifunctional control. A detailed comparison between existing ES control schemes and the proposed ISCA approach highlights the benefits of proposed control in terms of its multifunctional capabilities. The ES-1 utilises three-phase inverter with DC-link capacitor that compensates unbalance non-critical load and non-linear critical load. To demonstrate the effectiveness of proposed method to operate ES in APF mode, the results using MATLAB simulations are presented and compared with those few obtained for similar existing control schemes. The proposed control is also validated using experimental studies.
