• to identify and prioritise the stability-related issues faced by the TSOs considering different network topologies, geographical locations and penetration levels of PE (generators, HVDC converters, FACTS, loads);
• to develop novel approaches and methodologies able to analyse and mitigate the impacts of PE penetration on power system stability based on simulations, laboratory scale experiments and PMU measurements methods (data supplied by WP2);
• to propose control strategies so as to further tune and coordinate existing system controls in order to maximise the penetration level of PE considering the current operating rules, the existing control and protection devices and the available degrees of freedom in the network codes (RfG and HVDC grid codes as well as the DCC);
• to validate the use of a monitoring approach of the PE penetration based on-line PMU measurements methods developed in WP2.

The research and development will address the following issues:

• New KPI, such as Area Inertia, will provide a new dimension to the analysis of system performance during the transition to a low carbon transmission network mainly based on PE connected generation;
• New monitoring and forecasting tools can be developed using modern sensors (e.g. PMUs) and communication technology to provide real-time information on KPIs (including area inertia, wide band oscillation characteristics and short-circuit capacity) to more accurately assess the true stability limits of a system;
• The step change to a world first live implementation of a real time wide area control algorithm can be developed and tested in the GB and Icelandic networks;
• Demonstrate that the solutions created are capable of maintaining a high level of accuracy and reliability for a range of different power systems, beyond those they were originally envisioned for, and as such are ready for pan-European application. Furthermore, by trialling the solutions in different systems, valuable insights into the interoperability between hardware from different suppliers, and between different hardware and software platforms will be generated to facilitate further development and help ensure the solutions can be up taken by any EU TSO.

• to propose and develop novel control and management rules for a transmission grid to which 100 % converter-based devices are connected while keeping the costs under control;
• to check the viability of such new control and management rules within transmission grids to which some synchronous machines are connected;
• to infer a set of requirement guidelines for converter-based generating units, as far as possible set at the connection point and technology-agnostic, which ease the implementation of the above control and management rules.

• Provide a detailed insight into the ability of actual protection practices to properly operate under system disturbances under very high penetration of PE trough simulations with Hardware in the Loop (HiL) tests.
• Evaluate and test emerging technologies together with new system protection strategies and develop new ones in order to overcome the identified threats when operating at 100% of PE penetration.
• Give recommendations relative to the design of protection schemes for future power systems with very high penetration of PE.

WP5 addresses the following objectives in the wake of the scenarios studied in WP1:

• to develop and validate a focused set of simulation models of PE devices for PQ studies in line with the scenarios studied in WP1, which allows evaluating their influence on PQ in transmission networks;
• to identify critical PQ disturbances in order to numerically study their propagation through transmission networks in line with the retained WP1 scenarios (different levels of PE penetration and different network operating conditions)
• to examine how far the use of PMUs can assist in the mapping of PQ issues, including the implementation of realtime data retrieval;
• to analyse the impacts of PQ disturbances on the performance of PE devices;
• to combine the above findings into a methodology and numerical models which can be used by TSOs to assess PQ
• issues in future power systems experiencing WP1-like scenarios and to propose appropriate, cost-effective mitigating solutions to reach a required level of PQ.

• to quantify the technology and economic impacts of the laboratory and field tests performed by the consortium.
• to detail the technical, economic and regulatory barriers to be overcome before proper scaling and replication of the grid connection rules and power system control laws.
• to recommend a deployment roadmap for the grid connection rules and power system control laws, including tentative improvements of the existing grid codes related to generation (RfG) and consumer connection rules (DCC).
• to propose exploitation plans of the two project results owned by the participating free-market players.

• to develop a Communication and Dissemination Plan guaranteeing the technical, market and public coverage of the project results
• to support the exploitation of the project outputs by consolidating the project visibility among stakeholders at EU level and towards users through a project website and additional dissemination and communication tools and materials
• to enable smooth communication and knowledge sharing among the targeted stakeholders at EC level

• to adequately coordinate and organise the project at strategic level;
• to safeguard a smooth and target-oriented implementation of the project in line with the time and budgetary restrictions, ensuring:
  • project follow-up (project progress control and planning),
  • high-level commitment,
  • decision making procedures,
  • suitable project administration.
