Assessment of Power Profiles in LV Distribution Grids

Power profiling is important for upper-level models used in applications for analysis of low voltage (LV) distribution grids. Characteristic profiles that use energy-related information coming from the metering infrastructure with low reporting rates (e.g., 1hour, 30-, or 15-minutes) are usually assumed, depending on the application type for which they serve as input. The advancement of smart metering using higher reporting rates (e.g., 1 frame/s or 1 frame/min) may enhance the assessment of details in power profiling for LV distribution grids. An analytical-based framework for quality assessment of power profiles in LV distribution grids is proposed in this study. The framework is useful to quantify the adequacy of an assumed power profile model, especially for applications dealing with the operation and planning of microgrids or energy communities.
