| Abstract | This study investigates the performance of finite control set–model predictive control (FCS–MPC) strategy employed for the control of active (P) and reactive power (Q) injected to the grid from a distributed energy resource using a single-phase grid-tied inverter. In the study, three different computational methods are utilised to create the orthogonal components of grid current and voltage in the stationary reference frame that are required for PQ computations. The obtained results indicate that FCS–MPC approach is effective to provide flexible control of the power injected to the grid. Moreover, the steady state and transient performance of P and Q components are affected by the method of creating the imaginary quadrature component. Owing to the results, the second-order generalised integrator method provides the best steady state performance in terms of the lowest total harmonic distortion of grid current and minimum resultant peak–peak power ripple. While the quarter cycle phase delay method results in the worst transient behaviour owing to an unavoidable time delay of 0.005 s in case of 50 Hz supply system. In addition, the robustness of the FCS–MPC system is examined against parameters variation over a wide range. The overall FCS–MPC system is studied using PSIM® software. |

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.
