Peak Demand Dynamics of Low-Voltage Consumers Under Aggregation and Its Impact on Upstream Pv Injection

Abstract

Renewable Energy Communities will allow consumers on the low-voltage grid to actively participate in the energy market. This work explores the dynamics of the daily peak demands of these communities under aggregation, as multiple countries are introducing capacity-based grid tariffs for residential consumers. Both the aggregation level and yearly consumption of the households comprising it are shown to have a significant impact on the timing of the daily peak demands. While considering both the size of the PV installation and its orientation as variables, it is subsequently shown that this effect of the aggregation level is extended to the PV self-consumption and self-sufficiency indices.
