This report presents the key findings from several studies that were completed as part of the Carnarvon DER Trial covering topics such as aggregated unmasked load, minimum system load, the effect of PV generation and cloud events on voltages in LV networks and spinning reserve requirements, incorporating short-term solar forecasting and feed-in management in spinning reserve strategies and all sky imager nowcasting systems.
Report extract
This report:
- Presents the study on the unmasking of the load for a subset of the Carnarvon load using the project’s unique data set, namely the Wattwatcher data, which recorded net load and PV and battery generation at the premises of the trial participants.
- Provides the results of an analysis completed by Murdoch University of SCADA data to determine the minimum load seen by the Mungullah Power Station in Carnarvon during the analysis period 2017-2020.
- Discusses the effect of PV power generation (and cloud events) on LV network voltage based on a study of the voltages on two LV networks in Carnarvon. High voltage events may be exacerbated due to the measurement of the voltages analysed in this study not being at the point of supply (i.e. it is not a Horizon Power network voltage), but a voltage measured within the customer’s switchboard, which is downstream of a lead-in cable.
