The relative size of energy demands from domestic water and space heating make them ideally suited for providing demand-side flexibility services. However, co-ordinated operation of flexible devices results in coincident changes in demand on adjacent low-voltage (LV) networks, and can therefore lead to a coupling of voltages between circuits. In this work, water heating temporal flexibility and space heating vector flexibility (from hybrid gas–electric heat pumps) are enabled across a network service area, and the voltage changes measured using the proposed ‘flexibility voltage modulation’ index. It is demonstrated that integrated medium-voltage (MV)–LV modelling increases the mean voltage modulation threefold and the variance of the voltage modulation by 70% when compared to results from an isolated LV model. The work, therefore, demonstrates the crucial role of MV networks in LV circuit simulation.
