| Abstract | 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. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
