In 2017, he received the Italian National Scientific Qualification as Full Professor in the sector of electrical energy engineering. His main research interests are in: power systems design and control; power system conversion; PV, CPV electrical and thermal design, characterization and testing; microgrids and smart grids modelling and analysis; multi-objective optimization applications. He is a member of IEA task 11 “PV Hybrid systems within mini-grids” and task 14 “High penetration of PV systems in electricity grids” and of Italian Electrotechnical Committee (CEI) CT 82 “Solar photovoltaic”, CT 316 “Connection to LV, MV and HV distribution networks” and CT 313 “Smart grids”. He is operating as Italian member for Mission Innovation Challenge 1 “Smart Grids” and Challenge 2 “Off-grid access to electricity”.

He is the responsible of National and European (FP7, H2020) projects within renewable energy and smart grid topics. He is the vice-coordinator of Joint Programme on Smart Grid (JP SG) within European energy Research Alliance (EERA). He has supervised several MSc and PhD theses. He is also peer review, member of editorial and advisor board of scientific journals, and chairman in international conference. He is author of more 200 scientific papers published in the proceedings of international conference and journals.

Work packages (WP)

WP1 – Coordination and project management
Leader: ENEA

The management task focuses on a centralized control and monitoring with the transferred responsibilities to work package leaders and task leaders. This work package is linked to all the others and ensures communication among work packages, and between the INTERPLAN project and the European Commission.

WP2 – Technical assessment and regulatory status of the European electricity grid
Leader: UCY

The main objective of this WP is to identify relevant basis to later define significant use cases and a clustering method. Emphasis will be put on exploitation and analysis of previous projects and studies, considering both the pan-European level (transmission grid) and the flexibility present in the distribution grid. The WP pays specific attention to addressing flexibility possibilities coming from storage and demand response singly or aggregated.

WP2 concentrates on the technical assessment of the state of the art national and European practices, regulatory and grid code practices with the aim to identify possible steps towards an integrated planning tool for the implementation of new control and operation approaches at all network levels (transmission, distribution and transmission-distribution interfaces). Moreover, WP2 aims to quantify the basis for defining significant use cases and adaptive clustering methods that can facilitate the INTERPLAN targeted planning and operational objectives.

WP3 – Requirements, scenarios and use cases definition
Leader: DERlab

The main objective of this work package is to define the requirements and the use cases for the INTERPLAN integrated operation planning tool. The requirements and the use cases defined in this WP will set the scope for the implementation in WP4-6. The requirements and the use cases will be based on the regulatory framework and grid code analysis done in WP2. Further objectives of this WP are to:

● Define the use case for network models (TSO, DSO, TSO-DSO interface) and grid equivalent models
● Select the specific requirements that should be covered in INTERPLAN models
● Select a set of use cases to be implemented in the INTERPLAN models covering the specific requirements

WP4 – Grid equivalenting
Leader: AIT

WP4 aims to provide and generate grid equivalent models to be integrated in the operation planning and semidynamic simulation environment in WP5. This will be done based on the developed INTERPLAN use cases and requirements within WP3. WP4 will receive demand and requirements for improvement of the grid equivalents from WP5 and WP6.

As a result, the WP will provide and deliver grid-equivalents covering all voltage levels to be incorporated in WP 5.

WP5 – Operation planning and semi-dynamic simulation
Leader: ENEA

The objective of this WP is to develop the control systems to be integrated in the INTERPLAN tool for transmission, distribution, and transmission-distribution interfaces within the interconnected grid.

In WP5, different showcases will be established, based on several operation planning criteria such as small-signal stability assessment, dynamic stability assessment, voltage stability assessment, maximizing RES share in generation portfolio in a secure manner, and OPF for minimization of losses and costs, as well as on the varying behaviour of power system objects subject to planning, such as RES, demand, and flexibility resources. In order to develop the control systems to be integrated in the INTERPLAN tool for transmission, distribution, and transmission-distribution interfaces, semi-dynamic simulations of grid equivalents will be performed for each identified showcase.

This WP will strongly interact with WP3, WP4 and WP6. Relatively to this latter, the testing results will be sent back to this WP, with the aim to improve the control systems developed.

WP6 – INTERPLAN model validation and testing
Leader: Fraunhofer IWES

This WP will realize the use cases proposed by WP2 and WP3 in a simulation environment. It will also validate, test and verify the developed models and tools from WP4 and WP5. The real time co-simulation environment will eventually be used as a tool for the demonstration of the “proof of concept”. This WP will contain the processing and realization of the use cases from WP2 and WP3 as well as the preparation of the simulated networks. The operational tools will be tested on scenarios built up on the use cases.

WP6 aims to realize the interfaces described in WP3 in order to provide a seamless connection between the simulation environment and the operational tool and network models. A steady evaluation of the actions and performance of models and tools will be done in order to provide a continuous evolution of the methods.

WP7 – Dissemination, communication and exploitation
Leader: DERlab

This WP carries out dissemination and communication of non-confidential scientific results to the industry and scientific community during the project execution. The WP ensures that the newly developed knowledge will be exploited on broad international scale among industry, key users, national and international authorities, standardization bodies and other relevant stakeholders.

The European Union (EU) energy security policy faces significant challenges, as we move towards a pan–European network based on the wide diversity of energy systems among EU members. In such a context, novel solutions are needed to support the future operation of the EU electricity system in order to increase security of supply also accounting for the increasing contribution of renewable energy sources.

INTERPLAN is a project that aims to provide an INTEgrated opeRation PLANning tool towards the pan-European network, to support the EU in reaching the expected low-carbon targets, while maintaining network security. INTERPLAN will provide a methodology for a proper representation of a “clustered” model of the pan-European network, with the aim to generate grid equivalents as a growing library able to cover all relevant system connectivity possibilities occurring in the real grid, by addressing operational issues at all network levels (transmission, distribution and TSOs-DSOs interfaces).

In this perspective, the chosen top-down approach will actually lead to an “integrated” tool, both in terms of voltage levels, going from high voltage down to low voltage up to end user, and in terms of building a bridge between static, long-term planning and considering operational issues by introducing controllers in the operation planning. Proper cluster and interface controllers will be developed to intervene in presence of criticalities, by exploiting the flexibility potentials throughout the grid.

The project ensures to achieve its goal by subdividing the necessary steps in seven work packages, each of them with a specific measurable objective.

The project is in line with the Work Programme in ensuring more flexibility and active involvement of all stakeholders, and a close coordination of TSOs and DSOs. Moreover, its versatility in the concept of grid equivalents, will allow an accurate analysis of the complex network, by considering local active elements in the grid.
