Overview of embedded generators in public electricity networks

Regional Electricity Companies (REC´s) operate public supply networks with typical voltages of 132 kV, 33 kV, 11 kV and LV and these are also host to embedded generators. Statutory conditions and power supply quality must be maintained at all points since there are frequent customer connections. Here, the author presents an overview of main issues associated with connection of generators to public electricity networks. Other issues are settings, stability and synchronising and the requirements for metering active and reactive energy and other operational measurements
