Micro Grid Automation with Unique Features of Power Flow Control by using SCADA

Now a days, the load demand of the world is dramatically increasing day by day. This situation creates a big gap between the energy production and the energy consumption. The conventional energy sources are depleting globally. So it is a global phenomenon to restore the power energy and to look forward the other means of energy production. The load demand and power production gap can be reduced by Micro Grid. Micro grids is a group of localized electricity units and load that operates both in islanded mode/ autonomously or in grid connected mode. Grid connected mode is a small power generating unit that is connected with conventional grid system. Grid connected mode is a small power generating unit that is being connected with conventional grid system. Micro grid mostly utilizes the renewable sources of energy such as solar energy, wind energy, geo thermal energy and the other sources of distributed generation. While operating a power system in micro grid, the maintenance and flow of electricity is not simple task as compared to the unidirectional power flow in case of conventional grid station. Another problem is the identification of fault in power system in case of micro grids detection of fault location and its recovery is not an easy task. In this research work, I have developed a SCADA module through which fault location is detected automatically, by observing the power at different feeders and its dial recovery is done by supply the power from other nearby power generating station. This is only possible when the system has ability to operate in ring main system, but it normally operates in radial configuration.
