Abstract: |
Renewable energy sources, such as wind and
solar, face several obstacles, including curtailment, where
the generated energy exceeds local demand and production
must be reduced because of limited transmission capacity.
Simultaneously, consumer demand for large-capacity batteries
is expanding given the recent rapid development of
electric vehicles (EVs) and plug-in hybrid EVs. A batterycharging
mode, in which discharged batteries are transported
from battery exchange stations in high-load areas to
wind farms, is proposed to alleviate curtailment. In this
study, batteries store otherwise curtailed energy and
smooth the wind power output simultaneously. The structure
of the battery-charging device is discussed, and the
concept of a battery-charging container is proposed. The
control principle of the battery-charging management unit
is presented with a simulation model constructed in the
PSCAD/EMTDC environment. A case study is simulated,
and the feasibility of the mode is analyzed considering the
levelized cost and energy losses. Simulation results show
that this mode is a feasible solution to alleviating wind
curtailment and providing fresh impetus for developing EV
battery exchanges. |
