Controlling the heating mode of heat pumps with the TRIANA three step methodology

Heat pump based heating systems are increasingly becoming an economic and efficient alternative for domestic gas heating systems. Concentrations of heat pump installations do consume large amounts of electricity, causing significant grid distribution and stability issues when the diversity factor is low. In this work, the three step control methodology TRIANA is extended to support the control of a heat pump fleet in order to improve diversity. Simulations show that TRIANA can reduce the peak load by at least 25% and improve σ by 33% for a representative soil-water scenario. Mathematical optimization shows that further improvement is possible.
