Abstract:
Modelling the stationary and dynamic behavior of electrical demand is a complex task as its composition is strongly dependent on time and field of application. In addition, the load composition is changing in the long term due to technological progress (e.g. energy efficiency measures). As a result, distribution grids experience an increasing share of novel technologies (i.e. variable speed drives and LED lighting). This paper provides a methodical approach to investigate the resulting impacts on the aggregated load behavior in Germany from the perspective of the transmission grid. This is based on a combined load model, which enables the simulation of stationary and dynamic changes in active and reactive power consumption caused by changes in voltage and frequency.
