Objectives	The project will first investigate the capabilities of the existing QBs and use the results to better understand if new control strategies will allow more effective power flow control and help manage network constraints. It will then explore how innovative solutions in phase shift transformer designs could deliver transportable modular solutions sufficiently flexible to cope with future demand and the power flow changes expected during the energy transition. It will also investigate how numerous suitably sized and optimally placed power flow devices (e.g., QBs) can be effectively coordinated to maximise the transmission boundaries capabilities as well as minimise risk and ensure resilience and reliability.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=1Cost=2Supplier=1Data=2Total risk score =6 Low (L) The scope of the project includes the following work packages:WP1 Maximising power control capability of the existing QBsLiterature review on global experience of QBs & Phase Shifting Transformers (PSTs).Assess advantages and disadvantages of QBs & PSTs vs other types of power flow control devices.Evaluate capabilities and limitations of existing QBs from a plant perspective (e.g. single/dual core designs, core saturation at extreme taps, OLTC current limiting resistor thermal capability and tap ranges & controls).Investigate viability of using QBs & PSTs with fast power electronic tap changers.Identify root cause of the existing QB tap operating constraints & recommend solutionsEvaluate benefits of utilising a full tap range for existing QBs (e.g. power flow capability). WP2 Development of coordinated control of multiple QBs.Literature review on coordinated control of multiple QBs.Compare benefits of coordinated control of multiple QBs vs non-coordinated control of QBs in accordance with existing NG-ESO guidelines (e.g. impacts on constraint management).Conceptual design of integrated control algorithm designed to co-ordinate the tapping of multiple QBs at strategic locations within the network.Determine impact on overall network performance of proposed coordinated control algorithm, with respect to power flows, voltages, short-circuit faults, dynamic stability, switching transients and network protection.Recommend future coordinated control strategy for QBsWP3 Conceptual design of modular, compact mobile QBs/PSTsInvestigate how physical size of QBs & PSTs is affected by operational tap range, power and voltage rating, single or dual core, asymmetric or symmetric design, core material, core saturation and losses.Detailed study into design of QBs & PSTs using FEM simulation software (COMSOL).Initial design of compact mobile QBs & PSTs with associated OLTC or fast power electronic tap changers.Simulation studies to assess the performances of compact QBs &PSTs.WP4 Strategic sizing and location of power flow control devicesInvestigate optimisation of sizing and location of QBs/PSTs in the GB network.Preliminary investigation into sizing and location of QBs/PSTs in combination with other type power flow devices (e.g. SSSCs-) in the GB network.Produce recommendation for sizing and locating future power flow control devices to maximise transmission boundaries transfer capability. The objectives of the project are as follows:Identify solutions to maximise power flow control capability of the existing QBs.Develop an algorithm for coordinated control of multiple power flow control devices.Develop an innovative modular and compact PSTs/QBs design that enables implementable flexibility and mobilityRecommend strategic sizing and location of power flow control devices for an evolving future network.
Abstract	The Enhance Power Flow Control Capability (EPFCC) project will investigate the operating performance of existing Quadrature Boosters and use the resulting knowledge to better understand if new control strategies will allow more effective power flow control and help manage future network constraints. It will also explore how innovative solutions in phase shift transformer designs could deliver transportable modular solutions sufficiently flexible to cope with future demand and the power flow changes during the energy transition. It will also investigate how numerous suitably sized and optimally placed power flow devices can be effectively coordinated to maximise the power transfer capabilities of critical transmission boundaries, whilst minimising risk and ensuring resilience and reliability.
