| Popis: | In this paper, previous theory and results regarding Low-Voltage (LV) distribution losses are validated through power-flow simulation using real load data with standard metering resolution. The validated results are then used to build a generalized loss prediction model for arbitrary grid topologies and metering resolutions. The paper provides the theoretical background to build and generalize a loss prediction model based on load variances together with an approach to estimate such variances. The prediction model uses as explanatory variables the variances of the loads. Yet, such variances are usually unknown for the higher metering resolutions, so the model also proposes a method to predict the higher resolution variances based on the standard metering ones. Results are presented to illustrate the approach proposed and to estimate the increase in losses expected for typical LV grids. |
