Abstract: |
In order to cut greenhouse-gas emissions and
increase energy security, the European Commission stimulates
the deployment of intermittent renewable energy
sources (IRES) towards 2050. In an electricity system with
high shares of IRES implemented in the network, energy
balancing like storage is needed to secure grid stability and
smooth demand satisfaction. Pumped hydro storage (PHS)
is at this moment the best option for large scale storage.
Switzerland has strong ambitions to further develop their
PHS sector and become the battery of Europe. In this
research, the potential of the Swiss PSH plants is explored,
whilst taking inflow into the upper reservoirs of the PHS
plants into consideration. To simulate electricity imbalance,
Germany is used as a case study. Germany already
has a high penetration of IRES and has plans to increase
installed IRES capacity. By using an energy planning
model (PowerPlan), three future scenarios of the German
electricity system were designed, each with a different set
of IRES installed (solar, mixed and wind). Results show
that the Swiss battery ambition offers most benefits to a
wind-oriented scenario, reducing both shortages as well as
surpluses. Water inflow in Swiss PHS-reservoirs is of
minor importance when looking at security of supply,
although it was shown that the solar-scenario profits more
from inflow in terms of system stability. However, a
potential conflict was observed in the solar-scenario
between the need for electricity storage and the storage of
natural inflow, resulting in more surpluses in the system
when inflow was taken into account. |
