The impact of Demand Side Management on the residual load

Abstract

In this paper, the effect of a Demand Side Management (DSM) on the residual load in Germany is shown. The used Demand Side Management model is focused on controlling heat pumps, electrical vehicles and white goods. The aim is to analyze the use of DSM regarding the increasing fluctuating power feed-in which is a result of the growing renewable energy sources (e.g. wind turbines and photovoltaic installations). The target function of the used model is to plane the residual load curve. To evaluate the influence on the German system load, the residual load curve will be analyzed with two key parameters: the shift potential and the volatility change factor. The shift potential expresses the maximum, simultaneous reduction of the peak of the residual load curve. The volatility change factor describes the relation between the diversity of the maximum and the minimum power before and after using the DSM. The effectiveness of the DSM by the used model is estimated and the outstanding points are declared.
