TNEI provided technical design and analysis during a recent successful bid for development consent. The aim of the studies was to derive preliminary cost, availability and electrical loss figures for three offshore windfarms in Dutch waters to facilitate the calculation of commercial bids for a government subsidy tender. To enable the client to meet their required timescales, this work had a very short turn-around time and had to be carefully co-ordinated.
TNEI formed part of a major Due Diligence team evaluating the potential for investment in each of the nine transitional OFTO assets on behalf of a global financial institution. TNEI was responsible for the assessment of risk on the electrical infrastructure and implications on availability and on-going operations and maintenance requirements.
Review and development of the offshore wind farm electrical infrastructure to provide a step-change that can deliver 10% life cycle cost reductions. TNEI was appointed by the Carbon Trust, in partnership with five international energy companies, RWE Innogy, Scottish Power Renewables, Airtricity Developments, DONG Energy Power, and StatoilHydro. The TNEI scope was to undertake extensive feasibility studies to address key technological, commercial and regulatory issues associated with offshore electrical system design.
Development of transient stability models in PSSE, PSLF and IPSA for most types of wind turbine technology. Involves working closely with manufacturers such as Siemens Wind Power, Nordex, Gamesa, Suzlon and others to assist in the reduction of detailed models to a suitable level of representation.
TNEI, in collaboration with Strathclyde University, provided the analysis capability to the three UK TSOs to develop and test different methodologies for inclusion of intermittent generation in the Great Britain Security and Quality of Supply Standard. This required the development of different stochastic tools to test the methodologies under significant number of trials.
Assessment of network reinforcement requirements for 2020 as part of the All Island Grid Project (Ireland), which included the use and development of state-of-the-art stochastic analysis tools. A key part of the work was to establish the capacity point at which incremental development was insufficient and a new EHV topology would be required.
We have provided in excess of 200 wind farm connection studies in UK for projects connecting to both Distribution as well as Transmission networks. We are providing ongoing embedded team support to Eirgrid for steady-state and dynamic assessments of wind generation connections. On-going support work for Eirgrid and NIE in the area of governor and AVR modelling and tuning for new and existing generation.
