Abstract
The ‘Delivering a Secure Sustainable Electricity System’ (DS3) programme has identified the need for integrating additional System Services in the Single Electricity Market (SEM) to operate the electricity system securely whilst achieving the renewable energy policy objectives of Northern Ireland. Distributed Energy Resources (DERs) are therefore expected to supply an increasing proportion of whole system support services in the future. This paper investigated the influences upon network capacity to accept the deployment of System Services, within ‘Northern Ireland Electricity (NIE) Networks’ electricity distribution system. The available capacity to host System Services within 33 kV and 11 kV was found to be influenced by several factors, and, in some cases, had a nonlinear relationship with the key influencers. Passive methods to assess network capacity and manage DERs were likely to unduly restrict system access. This paper put forth pertinent considerations that advocate the need for actively managed allocation of System Service, substantiating NIE Networks’ vision of evolving from a Distribution Network Operator (DNO) to a Distribution System Operator (DSO).
