The grid connected system is connected to a larger independent grid, usually the public grid and supplies energy directly into the grid. The
supply of electrical energy in the grid requires a synchronous grid connected inverter (also called grid interactive inverter) to change direct
current to other current. If there is a public electricity grid, the hybrid another energy system may be independent or grid linked. For
independent applications, the system must have sufficient storage capacity to handle power changes from the alternative energy sources
involved. This type of system can be considered a microgrid that has its own power generation and load. For grid connected applications,
alternative microgrid energy sources can power local loads and the utility. In addition to active current, these DG sources can also be used
to provide reactive current and voltage support for public electricity networks. If these systems are connected to the grid.
