Smart building potential within heavily utilised networks

Abstract

SP Energy Networks were involved in the research programme smart building potential within heavily utilised networks to assess the role that demand-side response (DSR) could play in providing the distribution network operators with an economic and readily deployable means of enhancing the capability of their networks. DSR trials were carried out across ten city-centre buildings in Glasgow. The average level of demand reduction of controllable loads across the whole year was found to be around 20%, which equated to a 7% reduction overall. Comms issues were found in some buildings, which resulted in gaps in data. Network models were developed that allowed the impact of DSR - taking the levels identified through live trials - to be modelled and a business case developed. The business case suggested that DSR is a cost-effective network support tool if low levels of load reduction are required. As the level of load reduction increases, traditional reinforcement is more cost effective.
