| Abstract | Multi-terminal DC grid can be embedded in meshed AC grid to increase power transmission capability and control power flow of AC grid. In addition to economic benefits especially in congested areas, the proposed solution can provide back-up for the AC grid and enhance power transmission capacity and flexibility. From the supervisory control point of view, a control algorithm is required to set the reference values for controlling the DC grid power flow based on the desired operating points of meshed AC grid. In this paper, the algebraic model of the DC grid is derived and validated in meshed AC power systems. Algebraic model will present the behavior of AC grid with respect to various operating points of the DC grid, and it is used for steady state analysis. This paper also proposes a droop control structure with dead-band controller for the DC grid. To verify the algebraic model and the control structure, dynamic performance of the embedded multi-terminal DC grid in a reduced order three-bus AC equivalent NYPA power system is investigated in PSCAD/EMTDC environment. |

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.
