Objectives To develop a full research and demonstration proposal under NIC mechanism for Ofgem and the Expert Panel to evaluate. To further develop, independent evaluate the existing proposal and fulfil the requirements set out under the NIC governance document
Abstract The VISOR project has been selected for promotion by SPT since it provides innovation to complement and underpin the technology integration challenge, promoting the acceleration of a low carbon energy sector and creating knowledge that will benefit all TOs, OFTOs and DNOs investing in new technologies. This project further provides the most effective compliance with the criteria cited Section 4. 9 of the NIC Governance document and delivers an industry need in a timely manner. In order to meet government energy policy, TOs are investing heavily in system upgrades, some of which deploy new technologies, i.e. embedded HVDC links and Series Compensation etc. The commissioning of these technologies on the GB transmission system leads to a finite risk of unforeseen and potentially damaging oscillatory interaction between transmission and generation plant and this may also impact on security of supply, if not appropriately managed. SP and NGT have previously installed Phase Measurement Units (PMU) that monitor system dynamic behaviour but this system has significant shortfalls in capability, i.e.it can only see oscillatory behaviours up to about 10Hz whereas new technologies may exhibit behaviours at higher frequencies up to the nominal system frequency i. e 50Hz. The current installed system provides no means of identifying the location or source of a disturbance. The existing planning and operation of the transmission system is based heavily on off-line deterministic studies and there are few opportunities to validate the results of the model against the real system performance. The provision of PMU data enables the network impedance to be accurately measured and the performance of dynamic models to be validated. The transmission boundary between Scotland and England is heavily constrained by voltage and stability limits. Stability limits are normally assessed by off-line study with the application of appropriate operational margins. There is currently no facility to use the real time system data to establish operational limits. This proposal will build on the existing PMU infrastructure installed in NGT and SPT network and will address the short falls in the performance and functionality of PMU based processing, to provide a "fit for purpose" monitoring system for the future GB transmission system. The system developed will be a hybrid to accommodate conventional PMUs and high resolution frequency analysis devices capable of recording the higher frequency disturbances that may be expected from new technologies in the future. The project will develop additional functions to enable the source of a disturbance to be identified. PMU data can also be used to validate network models for network investment planning purposes. The project will identify the optimum coverage and location of PMU sources taking into account the system requirements such as network topology visibility to assist with black start recovery and the communication infrastructure requirements for data transmission. Having acquired a GB wide picture of PMU data, this may be used in conjunction with other conventional power flow information, to provide a hybrid state estimation of "near real time" state variables. These state variables will be used with an analysis platform to derive real time voltage and stability limits. This shall facilitate real time dispatch and allow the full network capabilities to be used, whilst managing the risks identified in Section 2. 1. In the first instance, the project will establish a trial focused on the Anglo-Scottish transmission boundary (also known as B6) which is frequently power flow constrained, as a result of active system stability and voltage limits.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
