Objectives To produce a proof of concept paper and associated functional specification on the use of SCADA and ADMS to detect and fragment islands formed on the distribution network. This project will be considered a success upon production and publication of a proof of concept paper and associated functional specification on the use of SCADA and ADMS to detect and fragment islands formed on the distribution network. It is proposed that the outcomes of the project will be shared with industry experts and comments invited.
Abstract The amount of generation connected to distribution networks at all voltage levels has steadily increased in recent years which has led to parts of the network where generation matches or exceeds demand at certain points on the load curve. The requirements for grid connection of generators detailed in the European Network Code are currently undergoing modification which will allow the dynamic behaviour of generators and their protection and control facilities to change under certain fault conditions in order to preserve or to re-establish system security. In addition to the EU Network Code changes there are proposed changes to the GB Distribution Code to alter the Rate of Change of Frequency (RoCoF) settings for generators from 0. 125Hz/s to 1Hz/s. These wider settings help to stabilise the system from a national perspective. The emergence of commercial measures such as Demand Side Response (DSR) contracts used to balance system frequency, trading positions and network constraints have also increased in recent years. These contracts can result in some quite significant changes to the demand profile of the distribution network. The combination of altering settings or control on generators to allow them to remain connected for smaller system disturbances and the increase in demand and associated DSR will potentially lead to an increase in the risk of a generator supporting an islanded network on the local distribution system. The problem is how to reliably and economically detect when an island has formed and to determine what steps are then appropriate to take once an island has been detected. The project will investigate the use of SCADA and ADMS functionality to detect and then fragment islands formed on the distribution network. If the investigation proves successful a formal DCode modification could be prepared.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
