Aggregated Energy Flexibility Provision Using Residential Heat Pumps

The rising relevance of such concepts as smart grids and demand response has led to power systems that are more closely monitored and managed. Utilization of demand-side energy flexibility, which is currently a largely untapped resource, is considered a potential way to alleviate challenges surrounding the integration of renewable distributed energy resources. In this paper, the aggregated energy flexibility of residential heat pumps was simulated. A resistor-capacitor thermal network in combination with a state-space model was used to model the thermal response of buildings. A total of 1500 different buildings were modeled as part of the aggregators' portfolio. Response to flexibility activation was simulated with two different controls depending on the strictness of consumers regards temperature comfort.
