Climate change is becoming an increasing concern all around the world. The fossil-based sources of electricity generation are one of the primary factors of climate change. In many countries, the transition to low-carbon technology has already begun toward achieving zero-carbon targets. Electric vehicles (EVs) and heat pumps (HPs) are promising technologies to help tackle the source of carbon emissions. However, the uncontrolled application of these technologies could potentially result in unintended outcomes and damage the distribution networks. This research paper examines the hourly based electrical demand in a residential community using advanced multistage stochastic modelling methods. Moreover, this study investigates the sufficiency of the existing distribution networks in the UK for full EV and HP adaptations. The study also discusses the requirements for future grid systems to provide uninterrupted and safe electricity to end users.
