Evaluation on the application mode of distributed generation

A distributed generation system (DGS) consists of a cluster of DG (photovoltaic, diesel engines, wind-power, fuel cells, micro-turbines), has many advantages in improving the quality of voltage in rural power grid and solving power supply in remote area or rural areas. The paper investigates a number of practical projects application modes and put forward several different DGS application modes, such as grid-connected DGS, grid-disconnected DGS, micro-grid system, and then analyses the characteristic of these DGs application modes.
