Distributed Control of DC Grids: Integrating Prosumers’ Motives [PDF]
IEEE Transactions on Power Systems, 2022 In this paper, a novel distributed control strategy addressing a (feasible) psycho-social-physical welfare problem in islanded Direct Current (DC) smart grids is proposed. Firstly, we formulate a (convex) optimization problem that allows prosumers to share current with each other, taking into account the technical and physical aspects and constraints ...

Multidisciplinary Journal of Research in Engineering and Technology, 2014 Grid synchronization is the combination of two or more grids to fulfill the load demand. When main grid does not satisfy the load demand then it is synchronized with another grid to meet the load requirement. In this arrangement we are considering main grid as conventional grid and another one as non-conventional grid.

A modular multi-level DC-DC converter for HVDC grids
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016 A double-T DC-DC modular multilevel converter (DC-DC-MMC) topology for high-voltage dc (HVdc) applications is presented in this paper. The topology is intended to interconnect large power dc grids with different voltage levels or to control the power flow in meshed dc grids. A two level control hierarchy is used to regulate the dc voltage of each cell.
