Heat pumps, with their ability to provide ecofriendly heating and hot water, are crucial to the transition to climate-neutral buildings. However, these sustainable heating systems could overburden electric power distribution networks as their numbers rise. The Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Germany recently developed algorithms to reduce peak loads. Its researchers tested their new method in Sweden, where heat pumps see widespread use and winters are particularly frosty. The algorithms proved their merits: They help run heat pumps in an efficient, grid-friendly way that trims the load on the distribution network’s transformers by ten percent.
