Objectives	"This project will investigate the feasibility of using Digital Twin (DT) methodology to assist network restoration and implement adaptive protection. Conceptual development will be carried out to model essential power network components (both Primary HV plant and secondary P&C equipment) to digitally simulate the live operation of a power network. A Real Time Digital Simulator (RTDS) will be deployed with live data (fed from the Phasor Measurement Units (PMU) and other measurement devices) for both on-line system analyses and off-line equipment testing. Such a DT system will be capable of providing real-time decision-making assistance to network control, or adaptive protection functionality. A demonstrator of such a DT system will be built within a lab environment to showcase the capability of network restoration analyses and adaptive protection and control of the network.Data Quality Statement (DQS):The project will be delivered under the NIA framework in line with OFGEM, ENA and NGGT / NGET internal policy. Data produced as part of this project will be subject to quality assurance to ensure that the information produced with each deliverable is accurate to the best of our knowledge and sources of information are appropriately documented. All deliverables and project outputs will be stored on our internal Sharepoint platform ensuring access control, backup and version management. Relevant project documentation and reports will also be made available on the ENA Smarter Networks Portal and dissemination material will be shared with the relevant stakeholders.Measurement Quality Statement (MQS):The methodology used in this project will be subject to the suppliers own quality assurance regime. Quality assurance processes and the source of data, measurement processes and equipment as well as data processing will be clearly documented and verifiable. The measurements, designs and economic assessments will also be clearly documented in the relevant deliverables and final project report and will be made available for review.Risk Assessment: TRL Change = 1Cost = 2Supplier = 1Data = 2Total risk score = 6 Low (L) " "The scope of this project will include 4 work packages (WP)1 WP1 – Feasibility and FunctionalityWork Package 1 (WP1) is to understand and establish the functionality and architectural requirements for the digital twin (DT) system, includingSurvey study to identify appropriate methodologies and best practices to develop and assess the Local Joint Restoration Plan (LJRP).Establishment of the key functions for network resilience analyses and control, including real time calculation of SCL/network inertia measurement using PMU data, adaptive protection functionality and on-line decision-making capability for network control/switching.Conceptual design of an overall architecture to interface with PMU system data, incorporating LJRP Study tool, Adaptive protection and Hardwire-in-Loop tests.Conceptual design of the LJRP analysis tool, capable of performing wide area voltage and reactive management, Ferro-resonance analysis, CB Transient Recovery Voltage (TRV) study as well as assessing Grid Forming capability from IBG, batteries and HVDC interconnectors.Conceptual design of adaptive protection functionality with the coordination study capability to assess protection and control functions affected by SCL/Network Inertia.Define suitable models (e.g. RMS, Step-RMS and EMT) required for the analytical and control functions withthe DT system 2 WP2: RTDS Modelling and Functional DevelopmentWork Package 2 will be focusing on RTDS modelling to fulfil the on-line functions and off-line analyses within the DT system, includingDevelop RTDS primary system models suitable for network restoration analyses, including key network components, conventional and renewable generations as well as HVDC and FACTS devices,Develop RTDS secondary system models including protection and control devices and schemes, network automation functions (e.g. DAR, OTS, etc.),Build functional block for network restoration study using the RTDS models and the conceptual design from WP1,Build functional block for adaptive protection/on-line decision-making using the RTDS models and the conceptual design from WP1,Validate the developed RTDS models against the definition/specifications from WP1 or relevant international and industrial standards/reference.3 WP3 – Lab Demonstrator Work Package 3 is to demonstrate the feasibility and functionality of the DT system in the Lab environment, showcasing the key functions byBuilding a demonstrator of the digital twin system using the overall architecture from WP1 with the models and functional blocks from WP2.

Abstract	This project will investigate the feasibility of using Digital Twin (DT) technology to support local network restoration plans and the implementation of adaptive protection systems to address challenges associated with high penetration of Inverter Based Generation (IBG) within a power network. Conceptual development will be carried out to model power networks and essential equipment, and build a virtual “twin” system to digitally simulate the live operation. A Real Time Digital Simulator (RTDS) will be deployed with live data fed from Phasor Measurement Units (PMUs) for on-line decision-making and off-line testing/analyses. The project will showcase the use of such a DT system to support the local network restoration plan, in addition to adaptive protection capabilities to eliminate the risks of maloperation.
