R&D NESTER contributes to the creation of new grid planning and operation tools in the INTERPRETER project


R&D NESTER is contributing to the creation of new grid planning and operation tools, in the scope of the INTERPRETER project, financed by the H2020 programme. This project aims at developing a modular platform that allows including multiple tools for grid operation and planning. In the project scope, and to demonstrate the capabilities of the developed platform, 10 different tools are currently under development, to be later on provided to system operators. Some of these tools are only applicable to distribution systems, while others are applicable also to transmission systems, which is the case of the tools developed by R&D NESTER.

Results already obtained include the design of the platform architecture to be implemented and the definition of the functionalities of the different tools, through the creation of use cases. R&D NESTER is responsible for the development of two tools, which can be used in grid planning processes:

       Nodal Capacity calculation - optimization of the process of nodal capacity calculation in a network, aimed at received new generation units. The tool will follow a stochastic approach, as an example in contingency analysis, contrasting with the commonly used N-1 criterion.

       Optimal size and siting of energy storage units for congestion management - this tool uses an optimization algorithm to calculate optimal size and siting of energy storage units considering congestion management situations. Its solutions allow to have a direct comparison between costs for these storage solutions and grid expansion measures.

The set of tools developed in the project includes, as examples, solutions for phase balancing and detection of non-technical losses (applicable to low voltage networks). The tools developed by R&D NESTER will be tested with models of low, medium and high voltage grids, ensuring a transversal usage in power systems.

The project INTERPRETER started in October 2019 and has t duration of 36 months. The project activities are developed in a consortium, which besides R&D NESTER has 8 partners from Spain, Belgium, Greece, Denmark and France, including 2 DSO's from Belgium and Spain.
