Abstract / Description of output
The technical challenges imposed by increasing connection of distributed generation (DG), Distribution Network Operators (DNOs) require new voltage control schemes to manage the networks in a more active manner. In a conventional centralised scheme, voltage regulation is primarily performed at the substation according to the existing and predicted load downstream. However, this operation may leave other parts of the network where DG units are connected to experience problems such as voltage rise. Among the range of existing active network management schemes, a decentralised control wherein a distributed generator performs appropriate control actions at the point of connection to improve overall network performance may be a useful option. Aimed at minimising the impact of DG on the network's voltage profile, this work examines a decentralised control of DG. A power factor control-voltage control (PFC-VC) technique is demonstrated through a time-series analysis, considering firm and intermittent power generation. Results show that the proposed technique is able to effectively mitigate voltage rise.
