This paper discusses how the thermal side of a local energy community can offer flexibility to the electrical grid. In this regard, a model is presented in which a heat pump is used to connect low temperature heating and cooling networks and create flexibility being powered by renewables. This is done in combination with an overall control strategy aligning with production and demand across different energy carriers integrating the heat pump model with the thermal storage capacity offered by heating/cooling grids presenting the theoretical demand response opportunities in technical terms.
