Demand response based on smart metering infrastructure to facilitate PV integration in low voltage grids

Increasing penetration of distributed generation in combination with an aging grid infrastructure calls for a more flexible and efficient utilization of grid assets. Demand response is well suited to absorb peaks from local generation, but typically requires augmentation of the existing communication infrastructure to an extent that renders this option uneconomical in the context of low-voltage grids. In this paper we describe a pilot project where existing electric water heaters are controlled in dependence of local photovoltaic generation via the Advanced Metering Infrastructure.
