Abstract: The decommissioning of large conventional generators leads to growing challenges for the power system in maintaining local reactive power provision for voltage stability. Rather than installing expensive compensation devices, local multi-energy systems could provide reactive power on a local level. Therefore, this work assesses the impact of reactive power provision on the optimal design of a local multi-energy system with electricity and heat. Our analysis considers a local reactive power market, motivated by regulatory developments in Germany, under varying prices and temporal requirements, adopting an exact iterative second-order cone power flow formulation. Our results show that accounting for reactive power remuneration increases investment in the community battery energy storage system by up to 19.1% and the solar PV arrays by up to 4.3%, as additional revenue from reactive power provision and improved energy arbitrage outweighs higher investment cost. Heat pumps and thermal storage remain largely unaffected by increasing remuneration despite their reactive power provision. These findings highlight the importance of incorporating future reactive power markets into early-stage planning, as regulatory frameworks facilitate their market participation.
