摘要: After the decision on devolution of electric power generation, a great number dispersed storage and generation (DSG) units, which is mainly driven by renewable energy sources, has been connected to distribution networks. Existing DSG units in network converted traditional systems into active networks, are also called microgrids, created several technical difficulties from operation points view. Therefore, conventional protection control need be improved overcome these difficulties, provide reliable for microgrids operating both grid islanded modes. Today it realized that partially developments will not an ideal solution todays future microgrids. full automated certainly required proper This chapter deal with automation requirements schemes related fields.
