Objectives The objectives of the work is as follows: 1. Carry out a generic feasibility study on the performance requirements and functionality of a Smart Zone control system. 2. Increase security and stability of the transmission system. 3. Understand the performance and how reliable the IT comms system is along with any changes which may be necessary to withstand the future needs of the system. This project will be deemed successful if a portfolio of network transmission control strategy is developed that may be applied across Scottish Power transmission boundaries to facilitate the integration of large volumes of renewable generation onto the transmission system, in a safe, secure and sustainable way.
Abstract There is an increasing quantity of onshore and offshore wind generation and as a result the power flows across the transmission system are becoming increasing variable and unpredictable. In time this will compromise the security of the network as control engineers will lose the ability to ensure the system is operating economically. In addition as the system becomes more complex previous security systems, such as inter-trip systems which are designed to automatically trip generation or carry out automatic system reconfiguration, will become compromised. The system modelling effort required to manage special protection systems will increase and the duration and opportunity to engage special protection system may reduce significantly. The determination of the power system state pre and post fault is a key requirement in determining the post fault control action. The connection of generation to transmission boundary circuits leads to a very complex set of variables since the amount of generation to be tripped to restore security/stability will vary with the fault point, pre-fault transfers, generation background, parallel HVDC flows and other pre-fault network contingencies. This proposal will include a generic feasibility study that will identify the performance requirements and functionality of a Smart Zone control system identifying technology limitation i.e. state measurement, system modelling and communications etc. The benefits of employing PMUs in the determination of network states to inform post fault control will be evaluated. The project will identify project development costs for appropriate hardware and software system components. Having established the generic building blocks of a SMART transmission control system these will be applied to Anglo-Scottish transmission boundary where a range of technical solutions will be developed. The study will take into account the nature of the boundary limits, the volatile nature of boundary flow, the system configuration, the disposition of generation on or near to boundary circuits and the presence of embedded HVDC and Series Compensation OHLs across the transmission boundary. Any system proposed will require graceful degradation features such that failure of the system or its components will not cause a widespread failure of the transmission system. A key requirement of the study will be to understand the reliability and performance of IT comms systems and how these may need to change to full the future needs of the transmission system.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
