This presentation, from the Power Electronics Enabled Transmission and Distribution Systems conference stream, discusses the control of power flow in transmission and distribution systems using power electronic converters. The key to the provision of reliable and stable electricity supplies is the control of the real and reactive power flows in the network. A range of well-proven power electronic converters are available which can provide automatic control, either for long distance bulk power transfers or for the integration of distributed generation into the network. The presentation describes two families of converters.
