Objectives Develop methods and tools for assessing impact of distributed resource on the transmission network. Enable visualisation and assessment of the distribution network within transmission optimisation. Test methods for effective use of distributed resource for transmission purposes (direct control or DSO co-ordinated). Results and learning obtained from modelled trials of use of DER to manage transmission system constraints. Recommendations developed to progress from desktop study to large scale implementation and real-time trials.
Abstract The South East of England is anticipating significant changes in the way electricity is both generated and consumed. The transmission system is expecting to have to accommodate an increasing number of interconnectors and wind farms. The distribution system will see an increasing volume of embedded generation (solar PV in particular), along with changes to the type of demand such as an increase in electric vehicles, storage and demand side response (DSR). In order to prevent thermal overloading and to manage voltage stability, it is likely that significant network reinforcements will be required with both high costs and long lead times. When interconnectors transfer large amounts of power to or from the UK, the network in the South East will become heavily loaded. If the thermal loading gets too high the network can suffer a voltage collapse which can ultimately lead to a blackout. Additionally the large variation in the amount of loading on the lines causes high voltage issues during times of low demand. The nature of the changes from the demand side and within the distribution networks are likely to create higher voltages at both transmission and distribution levels particularly during low demand periods. This would require active management such as paying to constrain local generators to control the voltage. In the longer term, installation of reactive compensation equipment would be needed to prevent future incidents. In power systems with long distances between connection points, voltage collapse following a system disturbance may occur. If not mitigated this could lead to a system collapse. The mitigation of such an event traditionally requires the building and installation of new transmission lines, use of series compensation, and/or installation of large volumes of reactive power compensation. Without new economic and efficient solutions to address the aforementioned issues, costly network reinforcements with long lead times will be required. These may delay of limit the creation of new connections for GB consumers, thus limiting the opportunity to utilise distributed resources such as DSR, storage and solar PV. The purpose of this NIA project is to allow the studies required to determine the range of issues, innovative mitigating measures which need to be developed are carried out in a timely manner as per Work Stream 7’s timeline. This will also allow feeding the results into other Smart Grid Forum workstreams (i.e.WS6). Develop and perform trials to demonstrate use case scenarios based on historical data and known technical issues to study effectiveness of coordinated T&D approaches using DER against traditional methods.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
