The Wind Energy Institute of Canada (WEICan) acts as secretariat to Natural Resources Canada’s (NRCan) Utility Forum, which brings together representatives from utilities and system operators across Canada to discuss issues of shared importance specific to the planning and operation of power systems with high penetrations of variable generators (solar, wind).
The second task of the Utility Forum recommends opportunities to harmonize grid codes across Canada to lower the barriers to entry for further renewables development. Currently, traditional aspects for grid codes, such as voltage and reactive power support, balancing and regulation, power quality, and protection are fairly harmonized across Canada. However, emerging aspects of grid codes, such as those that emerged in response to inverter-based resources including, frequency support, large signal stability and performance during disturbance, and small signal stability are less harmonized across the provinces. Therefore, harmonization of grid codes across Canada should focus on emerging grid code elements.
