Compatibility Assessment of Transnational Grid Interconnection between the United States and Canada

Transnational grid interconnections are conducive to promoting optimal allocation of resource, reducing generation costs, balancing system load, and reducing system backup capacity. It is necessary to assess compatibility between collaborating countries in order to evaluate feasibility of transnational grid interconnections. Our previous research investigated compatibility assessment methodology in terms of political, social, economic and environmental aspects. This paper performs a case study using the compatibility assessment between the United States and Canada. The evaluation result indicates that the two countries are suitable for grid interconnections. The actual situation of the interconnection between the United States and Canada confirms that the evaluation result is reasonable. Therefore, the methodology promoted previously can be used in compatibility assessment of transnational grid interconnections.
