INTEgrated opeRation PLAnning tool towards the Pan-European Network

Periodic Reporting for period 2 - INTERPLAN (INTEgrated opeRation PLAnning tool towards the Pan-European Network)

Reporting period: 2019-05-01 to 2021-01-31

The goal of the H2020 INTERPLAN project is to provide an INTEgrated opeRation PLAnning tool towards the pan-European Network, with a focus on the TSO-DSO interfaces to support the EU in reaching the expected low-carbon targets, while maintaining the network security and reliability. Power system operation planning is a complex and multidimensional responsibility of the system operators and as such has been treated in this project. The project focused on several challenging and novel operation planning problems identified in the practice of today or expected to emerge tomorrow, for which appropriate solutions have been proposed. Within INTERPLAN, these solutions were developed in the framework of use cases, comprised of carefully selected models, system development scenarios, time series data and sets of planning criteria to be met. Subsequent showcases allowed to demonstrate not only accurate operation of developed controllers and algorithms, but also an ability to integrate use cases, so that several planning problems could be addressed simultaneously. The final development of this project is the INTERPLAN tool, which is a methodology for effective recognition of possible solutions applicable to identified problems in power system operation planning.
The main results achieved in the project are described below:
Delivery of a detailed assessment of existing grid codes, regulations and policies at European and national level, which influence the implementation of the emerging technologies (e.g. RES, storages, electric vehicles (EVs) and DR) into the grid.
Highlighting the main limitations of the existing grid codes at EU level through the public consultation process and the virtual workshop with external stakeholders.
Highlihgting the needs and the challenges that the different EU countries have to confront when adopting codes and policies for emerging technologies integration into the grid.
Spotting and exporting recommendations on amendments of the existing grid codes and suggestions for new ones to serve the seamless integration of the emerging technologies and addressing the identified needs.
Definition of seven INTERPLAN use cases which have been built up for addressing the main challenges for grid operation planning.
Definition of INTERPLAN requirements, which are assumptions and prerequisites of the defined use cases, and the prerequisites for running the technical actions planned in the project.
Collection and characterization of available network models at different voltage levels with the aim to build up realistic TSO-DSO grid examples.
Identification and characterization of a clustering method for distribution grids.
Development of a methodology for generating grid equivalents, that are based on the developed INTERPLAN use cases and showcases.
Development of the INTERPLAN tool and definition of the main concepts and functionalities of the tool.
Development and simulation of the control functions embedded in the tool, associated to the five INTERPLAN showcases.
Conduction of a proof-of-concept for one of the showcases to prove the applicability of the showcases simulation within the INTERPLAN tool platform.
Performing validation by quantitative and qualitative assessments of simulation experiment results showing that all use cases accurately address the identified operation planning criteria.
Completion of a successful proof-of-concept of the INTERPLAN tool as a methodology.
As for dissemination of the project results, seven fact-sheets were created based on the final project results and more than 15 individual experts interviews were performed by the project partners with external stakeholders in order to not only further promote the project results but also receive targeted feedback on project achievements.
Beyond the interviews with key experts, six workshops and sessions were organized, three of which took place in the last months of the project to present the final outcomes and interact with potential users. Due to the Covid-19, it was no possible to organize a physical final workshop as planned, but three online workshops were organized instead.
Moreover, to further increase INTERPLAN’s reach especially among the scientific community, the project was presented at several international scientific events through publications, verbal presentations and posters, obtaining a very good level of networking activities and dissemination of the results attained.
Regarding interaction with other relevant projects and initiatives, it is worth to mention that, only during the final project year, INTERPLAN partners cooperated with stakeholders of 21 EU-funded projects, as well as with national projects, European programmes, platforms and global initiatives. These collaborations have been fruitful and brought important feedback and insights to the project partners.
As for the exploitation plan, the main stakeholders for the project’s results were identified in TSOs, DSOs and regional security coordinators, since the INTERPLAN tool is aiming to achieve the operation planning of an integrated grid from the perspective of these grid operators through the efficient usage of RES and emerging technologies to solve operation issues occurring at all grid levels. The exploitation plan of INTERPLAN project, which is based on the instructions and guidelines provided by the EC, outlines and elaborates the key project exploitable results and their market potential and expected impacts, which are consisting of:
· integrated grid operation planning tool
· embedded control functions in the use cases of the tool
· analysis of grid codes
· grid clustering and equivalenting method
· further developments of the OpSim co-simulation tool
INTERPLAN advances over the known state of the art are summarized below:
-Designing an operation planning tool, which takes into account all voltage levels in an integrated top-down approach, going from high voltage down to low voltage
-Building a bridge between static, long-term planning, and considering operational issues by introducing controllers in the operation planning
-Focusing on specific issues occurring at TSO-DSO interfaces
-Developing control system logics which suit the complexity of the integrated grid
-Managing flexibility resources as “local active elements” within the grid
-On the policy front, identifying possible amendments to the existing grid codes.

The main potential impacts of INTERPLAN Project are in the following:
-Compatibility with the broad EU energy policy context: INTERPLAN addresses planning, development and operational issues of the integrated grid capable of handling effectively emerging technologies as a positive response to the needs of intermittent RES. INTERPLAN thus responds to the strategic objectives of EU for reducing emissions by 40% by 2030 and be No 1 in RES technologies.
-Optimized grid planning and design at European level, maximizing the capacity of the grid to host variable RES: INTERPLAN addresses operation planning aspects of the integrated grid from the European perspective without losing the myriad benefits of distributed resources and smart controllers spread throughout the grid. The grid equivalenting procedure of INTERPLAN integrated with the cluster and interface controllers, suits the complexity of the integrated grid as it will evolve through the adaption of the most competitive technologies in the sustainability trajectory.
