Identification Of Synchronous Generator Electric Parameters Connected To The Distribution Grid
Problems of the Regional Energetics, 2017 According to modern trends, the power grids with distributed generation will have an open system architecture. It means that active consumers, owners of distributed power units, including mobile units, must have free access to the grid, like when using internet, so it is necessary to have plug and play technologies.
