Canada is an immense country and while most of the population is concentrated near the US border,
there is more than 300 000 peoples living in isolated communities that are not connected to the
electrical grid [1]. In those remote places, electricity is produced using diesel generators at very high
economic and environmental costs. Since most of these locations possess good wind conditions an
obvious solution to reduce this burden is to couple a wind turbine with the diesel generator. However,
in the absence of a storage system, the penetration factor must be kept low due to the constraints
related to the operation of the diesel generator. This leads to a waste of the wind turbine electricity and
significantly reduces the economic interest of the method. Penetration factor can be largely increased
by the addition of an energy storage system. The utilization of the excess energy allows a much more
stable power and the complete stop of the diesel generators when they are not needed and a close to
optimal performance of it, which reduces their maintenance cost. Nevertheless, the optimization of the
whole system is critical to reach an adequate level of performance. This paper describes this
optimization process and the selected system concept.
