The limited supply of fossil fuel-based energies, and growing global concerns about the imminence of climate change are a leading cause as to why wind and solar are the fastest growing sources of energy in Canada. As renewable energy production increases, the stability of the grid system will experience detrimental impacts due to the intermittent nature of wind and solar energy. The irregularity of renewable energy can cause fluctuations in the grid voltage and grid frequency, and these fluctuations may jeopardize system stability. For instance, in Germany, once solar energy production reached 8% of their total energy production, they began to see a significant amount of fluctuations in their grid voltage and grid frequency.
