A Review on Voltage Control Methods for Active Distribution Networks
Published by Tengku Juhana TENGKU HASHIM1, Azah MOHAMED2, Hussain SHAREEF3, Universiti Kebangsaan Malaysia Abstract. Power distribution systems are in the state of transition from passive to active networks due to the rising penetration level of distributed generators (DGs). One of the technical challenges of active networks is to maintain an acceptable voltage level. This problemContinue reading “A Review on Voltage Control Methods for Active Distribution Networks”
