I. Introduction
The total residential energy use in 2016 in Canada was 1458 PJ, of which 60% was used for space heating and cooling applications [1]. This energy is mainly supplied by electric and natural gas Heating Ventilation and Air Conditioning (HVAC) systems which add to Green House Gas (GHG) emissions. Hence, there is a need for alternative, low cost, and more efficient clean energy sources for residential and commercial heating/cooling. In this context, the development, application, and market participation of Ground Source Heat Pump (GSHP) systems could play a significant role. However, for these systems to have an impact on the grid and its associated markets, aggregation through agents, typically referred to as a load aggregators, is a good option to add flexibility to electricity markets [2], since individual customer GSHP systems are too small and not eligible to participate in wholesale electricity markets.
