Objectives To progress detailed network studies to determine the suitability of MVDC as a reinforcement solution in specific cases. To effectively engage the MVDC supply chain and carry out wider stakeholder engagement to determine the wider benefits of MVDC across UK distribution and transmission networks. The key output of both 1) and 2) is to build confidence in the concept of MVDC solutions and ensure that the technical and cost input into the MVDC demonstration needs case is robust. To validate the use of existing AC circuit for DC operation Identification of Distribution/Transmission areas which will benefit from this technology; Detailed business case (including technical and commercial analysis) studies for one particular case to capture the tangible benefits; and The development of a fit-for-purpose provisional functional specification for an MVDC scheme.
Abstract ScottishPower is investigating the feasibility of transforming an existing 33kV circuit into a Medium Voltage Direct Current (MVDC) operation. There have been various studies already which have indicated clear potential benefits of MVDC as an alternative reinforcement at Distribution and Transmission voltages. Across the UK, increased levels of distributed renewable generation have contributed to a growing need for radical reinforcement solutions in areas of the network which are stretched to capacity. MVDC offers an innovative and powerful solution to increase thermal capacity and control flow at a critical point in the network. The distribution network is facing both thermal and voltage limits and significant reinforcement is required to accommodate the demand and generation growth anticipated over ED1. It would be expected, from the initial desktop studies, that converting an existing 33kV circuit to DC operation can increase the thermal capacity, as well as resolving voltage issues and limiting fault level. ScottishPower is requesting specialised support to develop these early studies further, and provide more in-depth analysis of its network to collect evidence from both transmission and distribution perspectives which will help to build up the business case for investment in an MVDC demonstrator. This project will gather the evidence required to support a strong business case, which may in turn lead to the first ever DC operation of an existing AC distribution network circuit in the UK, with all the benefits of improved thermal transfer capacity, voltage support and control of flows. There are significant learning benefits to be gained from such an innovative solution thatNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
