Title:Accommodating Distributed Energy Resources: Technical, Commercial and Regulatory Challenges
Speaker: Prof. Keith Bell, University of Strathclyde.

Location: Room H11, Renold Building, The University of Manchester
The installed capacity of distributed generation in Britain, i.e. that connected to the distribution network, has grown to over 23 GW and there are increasing amounts of distribution connected demand response and battery storage being offered either to the Electricity System Operator or the local Distribution Network Operator (DNO). However, it is not yet clear how these resources would be best managed both to minimise potential adverse impacts on the electricity system as a whole and to realise the opportunities they present.
This talk discusses the technical, regulatory and policy challenges inherent in planning and operating power systems with high penetrations of Distributed Energy Resources (DER): distribution connected generators, flexible demand and energy storage. Starting from the premise that optimal distribution networks are those that satisfy the objective of a lowest cost power system whilst meeting customers’ expectations of reliability and societal desire for sustainability, it highlights major challenges that utilities and policy makers face. These include the need to respect the technical limits of the system and ensure its operability, development of well designed mechanisms to support innovation, and an appropriate share of risk between market actors. Possible tensions between an ESO and DNOs are explained along with the opportunities offered by more active distribution system operation as a substitute for capital investment. Different proposals for how a DNO might transition to a Distribution System Operator (DSO) are discussed along with their regulatory and policy implications. Finally, a set of principles against which to judge different future regulatory and commercial models is presented.
