Abstract

Solar energy has a great possibility to be used as a source of renewable energy to be used as a source of electricity generation and the role of smart grids in the future. Micro grid is power generation, utilization and grid connection while built upon the generation, control and utility connections. This system serves to protect the sensitive and critical loads during abnormal grid conditions. Despite the many advantages that can be obtained using this system, but many lack in the building process of micro grid had been observed including the appropriate ways and aspects must be considered to detect when there is no grid connection. Common way is to take voltage readings at the point of common coupling. This method uses the 9th harmonic injection as a disturbance to make the system disconnected from the grid and using different loads on the inverter after LCL filter as an emergency load. This method should also qualify for the current situation there is no power grid available in the IEEE 929-2000, IEEE 1547. The time required for this situation should also be observed for less than what was required.
