TECHNO-ECONOMIC ASSESSMENT OF PV FORECAST ACCURACY FOR A PREDICTIVE CONGESTION MANAGEMENT AT THE DISTRIBUTION LEVEL

With the increasing penetration of distributed energy resources (DER) in power systems, the need for forecasts at the distribution level increases. In Germany, the upcoming redispatch 2.0 procedure will require DER forecasting and forecast-based congestion management at the distribution level. This paper evaluates the techno-economic benefits of advanced PV forecasts for predictive congestion management at the distribution level. The effectiveness of predictive congestion management at the distribution level strongly depends on the congestion forecast accuracy, thus in PV dominated grid sections, especially on the PV forecast accuracy. Furthermore, the paper gives insights into the evaluation chain of PV-forecasting applications for distribution system operation.
