Objectives For National Grid (and other utilities), to develop a new independent methodology which can be repeatedly and effectively applied to assess: 1) the impact on P&C systems for future applications of power electronic devices; 2) post-delivery circumstances in the future when the networks adjacent to existing power electronic devices change as a result of customer behaviour (e.g. new generation or demand applications). In general, a successful project will see a cost-effective methodology being established to assess the impact of power electronic devices on the performance of existing P&C systems of power networks and to reduce the associated risks as well as see in-house skills and capabilities being developed to understand and manage P&C systems for future complex network conditions which involves power electronics devices. According to Scope of Work, three specified work packages need to be completed on time with key deliverables as follows: Project progress report for WP1 (Feb, 2016)Project progress report for WP2 (Aug, 2016)Project progress report for WP3 (Feb, 2017)
Abstract Power electronic applications are increasingly being used to improve the network capacity or maintain the performance of the existing power system. This includes devices such as Flexible AC Power Transmission System (FACTS), High Voltage Direct Current (HVDC), power conversion systems for Energy Storage and Wind Power Generation. An example is the Thyristor-Controlled Series Compensation (TCSC) which has recently been commissioned by National Grid to enhance power transfer capability between England and Scotland. A number of new projects which employ power electronics are being planned for either connecting to or being embedded within the National Grid electricity transmission (NGET) network. These include dynamic shunt reactive compensation devices (Static Var Compensation (SVC) and/or Static Compensation (STATCOM)) along the south coast to provide voltage profile management during certain fault conditions to comply with Grid Code limits and new HVDC links (including Western HVDC Link) which will connect to or be embedded within NGET system. This strategy to integrate FACTS and HVDC devices into the power network introduces a range of new risks to network operation. One particular set of risks is the impact on performance of existing protection and control (P&C) systems for the circuits connected or adjacent to the FACTS and HVDC devices. Such risks include impedance changes which affect distance protection, coordination and speed of intertrip systems and the response of multiple control loops for different devices (e.g. generators, HVDC, FACTS devices). If not assessed and managed properly, these risks may lead to severe consequences such as loss of system stability, partial and total system blackouts as well as consumer and generator damage. At this time, there is no existing methodology or facility within National Grid to assess these future risks during project development and post-delivery support. The service can be provided by manufacturers as part of a scheme. However post-delivery support is not as readily available. Therefore there is a growing need to develop such facilities to assess the performance of P&C systems as the networks evolve and projects interact. A new methodology will be developed to model the FACTS device and adjacent circuits using a Real Time Digital Simulation (RTDS), this will cover the performance of P&C systems under both steady-state and dynamic conditions. The new methodology shall be validated using historic test data such as the Hutton TCSC project to demonstrate a reliable and repeatable set of results.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
