| Abstract | DC grid technology is an effective approach to implement large-scale renewable energy integration and accommodation. However, because of randomness and volatility of renewable power generation, the stability and efficiency of the power grid with high penetration integration will be weakened. This study proposes an energy storage-based control for the multi-terminal DC grid, and a way of integration in photovoltaic stations and wind power generators. The energy storage unit will be inputted into the multi-terminal DC grid to provide power support so as to eliminate the fluctuations of renewable energy and stabilise power flow of AC grids. Firstly, the four-terminal DC grid topology is established, which includes wind power generation, photovoltaic power generation and energy storage unit. Also, the corresponding system control strategy is designed. Then, by using the PSCAD/EMTDC platform, the equivalent simulation model of DC grid is built and the simulation studies are carried out under different conditions. Simulation results show that the proposed control strategy based on energy storage unit can eliminate the fluctuations of renewable power effectively. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
