| Abstract | The number of power inverter installations feeding renewable energy to AC grids is worldwide increasing. The type of inverter used depends on the power level and on the AC system conditions at the terminal connection point. Line-commutated inverters need sufficient short circuit power. Self-commutated inverters can even operate without an existing grid. In both the cases the mechanical inertia decreases in proportion to the installation of static generation. The main question to be answered is therefore: can inverters be equipped with electrical inertia so that the existing load-frequency controls will be maintained? This work combines an analytical approach using MATLAB with transient simulations using PSCAD/EMTDC. The results demonstrate that stability is achievable with no or low mechanical inertia. The results are relevant for distributed generation as well as for remote off-shore wind farms supplying bulk power via HVDC transmission systems into coastal areas. |

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.
