AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Digital Substation Platform Project Title Digital Substation Platform Tier 1 DNO SSE Status Complete LCNF project funding £360k Project objectives The scope of this project is to deploy a trial system with protection and ANM functionality together on the same hardware platform in a test environment i.e. the PNDC. Objectives: 1 - Demonstration of data integration and interfacing between the two platforms; 2 - Simulated control of a generator to allow the management of voltage on the network; 3 - Protection of primary assets using Locamation's suite of protection algorithms; 4 - Definition of a methodology for deeper integration in Phase 2. Assessment Criteria Accelerates the development of a low carbon energy sector Score (1-5) 3 Overview of assessment, sources of evidence and comments Assessment: The project clearly facilitates one of the carbon benefits: Provide reactive power services/ Provide frequency response service/Defer asset reinforcement. The carbon benefits not specifically quantified. Evidence: A learning outcome of the project was ‘Simulated control of a generator to allow for the management of voltage on the network’. This showed that voltage management was possible for both Real and Reactive power using generation control. References: • Digital Substation Platform; Closedown report; April 2015.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Has the potential to deliver net financial benefits to future and/or existing customers Has a Direct Impact on the operation of a DNO’s Distribution System Generates knowledge that can be shared amongst all DNOs - 2 4 Assessment: Little or no evidence that the project will deliver immediate benefit to customers, although these may occur in future. Evidence: Financial (or other) benefits to customers not discussed in the project closedown report. The project outputs feed into the NIA project. So customer benefits are anticipated at a later point in time. References: • Digital Substation Platform; Closedown report; April 2015. Assessment: The project has demonstrated functionality in a test environment which may be utilised in later NIA projects. Evidence: The project has undertaken an assessment of the qualitative benefit in using digital protection systems, so that further digital systems can be installed using the same hardware, This has helped progress and inform the future IT architecture required for substation protection, control and monitoring. For example the learning from this project has been used to inform discussion between SSEPD and NGETSO on the future ANM interface at GSPs. Workshops were held as part of the project to consider the transition towards a business as usual roll-out for the Digital Substation project. Outputs included agreement on drafting of a proposal for the NIA project, which the outcomes from the digital substation project has fed into. References: • Digital Substation Platform; Closedown report; April 2015. • Questionnaire response Assessment: Specific replication report(s) / information exist. There is no evidence of a learning dissemination event or webinar. Evidence: Table 6 and 7 in the closedown report outline components and knowledge required for project replication. Further detail is available on request from SHEPD through futurenetworks@sse.com. There is no evidence of a learning or dissemination event.
