Abstract To improve the security and reliability of distributed power and micro-grid in the operating off-grid to on-grid, this paper proposes a design scheme for micro-grid accessing to distribution-grid based on dual protection. This paper deeply analyses the operating off-grid to on-grid for grid-connected micro-grid, and gives the implementation strategy for the design scheme. The propose design scheme improves the reliability of the grid-connected micro-grid. On the other hand, it solves the synchronous conversion problem for micro-grid from off-grid to on-grid.
