Smart Energy Usage for Vehicle Charging and House Heating
In northern Europe the electricity price is set by hourly rates one
day in advance. The price fluctuates due to supply and demand, and
these fluctuations are expected to increase when solar and wind
power are increased in the energy system. The potential in cost
reduction for heating a house and charging of an electrified vehicle
by using a smart energy management system in a household is
investigated. Dynamic programming is used and a simulation study of
a household in Sweden comparing this optimal control scheme with a
heuristic controller is carried out. The time frame in the study is
one year and a novel way of handling the fact that the vehicle is
disconnected from the grid at some times is developed. A plug-in
hybrid electric vehicle is considered, but the methodology is the
same also for pure electric vehicles. It is found that the potential
in energy cost reduction for house heating and vehicle charging is
significant and that using a smart energy management system is a
promising path of cost reduction, especially with the introduction
of electrified vehicles.
