Sažetak

Recently, there has been an increasing interest in using distributed generators (DG) not only to inject power into the grid, but also to enhance the power quality. In this study, a space voltage pulse width modulation (SVPWM) control method is proposed for a synchronous grid-connected controller in a wind-solar-storage micro grid. This method is based on the appropriate topology of the synchronous controller. The wind-solar-storage micro grid is controlled to reconnect to the grid synchronously while maintance or repair is being completed to the power source equation DG at some point, the voltage difference that exists between DG and both sides of the node, a large and sudden electrical surge when DG is reconnected to the grid. It also affects the normal work of the other DG and power quality of a necessary load, and could even seriously paralyze the whole system. So, the topological structure and control method of the synchronous grid-connected controller are discussed in detail and simulation results are presented. The results demonstrate the effectiveness of the proposed method in the synchronous grid-connected controller for the wind-solar-storage micro grid.
