Active and Anticipatory Demand-side-management in Households

A high density of Photovoltaic generation can lead to problems in low voltage grids. This paper addresses the problem by actively and anticipatory using the load shifting and load influencing potentials in households. The goal is to achieve a local generation/load balance. To analyse the potential in Austrian households, a model settlement is generated, which represents Austria as a small village. For each device in these households an uninfluenced load profile is generated. Also the limits of load shifting are described. INTRODUCTION This paper addresses issues of integration of Photovoltaic (PV) generation in low voltage grids. In areas with a high density of installed PV power, situations occur where the power flow reverses when the generation power peaks exceed the maximum load. By reducing the peaks of the residual load profile, the share of decentralized renewable power generation can be increased. Demand side management (DSM) is often associated with the objectives of reducing peak load and smoothing the load curve. The goal within the project “aDSM”, however, is to achieve with DSM a very flexible electric load profile which adapts to the given volatile supply of renewable sources. Renewable generation forecast is an essential element to actively and anticipatorily use the existing load shifting potentials.
