Integration of electric drive vehicles in the Danish electricity network with high wind power penetration

This paper presents the results of a study carried out to examine the feasibility of integrating electric drive vehicles (EDV) in the Danish electricity network which is characterised by high wind power penetration. One of the main aims of this study was to examine the effect of electric drive vehicles on the Danish electricity network, wind power penetration and electricity market.

In particular the study examined the effect of electric drive vehicles on the generation capacity constraints, load curve, cross border transmission capacity and the type of generating sources (renewable/conventional) which are likely to fuel these cars. The study was carried out considering the Danish electricity network state around 2025, when the EDV penetration levels would be significant enough to have an impact on the power system.

Some of the interesting findings of this study are - EDV have the potential to assist in integrating more wind power (by adding more market value to wind power and by improving over all power system reliability) and integration of EDV does not require major additional infrastructure (generation/transmission cross border capacities).
