Laboratory for Electrical Networks and Devices (LEND) is actively participating in the four-year INCIT-EV project, funded by the European Union through scheme Horizon 2020, in the amount of almost 15 million euros. The purpose of the INCIT-EV project is to demonstrate innovative solutions for charging infrastructure, technologies and associated business models that will improve the user’s experience and consequently achieve use in the general public, which will accelerate the increase of EV market share in the EU. Part of the project is also to explore the behavior of EV users using the latest neuroscientific techniques, with which partners will also explore the unconscious preferences of EV users with the aim of adapting technology development to the subjective expectations of users. The project will directly involve 3,475 private electric vehicle users for dissemination and testing of various charging stations, as well as ten local communities, four taxi drivers associations, four car-sharing companies and four light electric vehicle-sharing companies. Project is run by Renault and involves 33 partners from eight countries. The Slovenian partners in the project are the Faculty of Electrical Engineering, University of Ljubljana and ELES.
Five demonstration areas in urban and suburban environments will be available to test seven applications:
- smart two-way EV charging, optimized at different stages of aggregation;
- dynamic wireless charging band in city centres;
- dynamic wireless charging over long distances;
- charging nodes in P+R car parks;
- super fast charging stations for European road corridors;
- charging stations for two-way charging of electric vehicles, including bicycles;
- occasional wireless charging at taxi lanes at airports and central train and bus stations.
These examples encourage the innovation of current charging solutions and at the same time the integration of these into the existing network, transport, ICT and public infrastructure. The project also aims to promote electromobility through user-oriented examples. A user-oriented approach will enable the creation of a new ecosystem and the development of charging technologies that could be widely used in EU Member States and accelerate the expansion of electromobility.
NSGP – National Smart Grids Plan
Changed conditions in the electricity system, mainly due to requirements for the production of electricity from diversified renewable sources, economical and efficient use of electricity, large cross-border energy transfers – as a result of the common European electricity market – and requirements for integration of new technologies (electric cars, dispersed production from renewable sources, production units connected to the system via power electronics, electrification of heating with heat pumps, energy storage, etc.), require new concepts of network design and operation and new innovative technological solutions, illustrated by the term smart grid solutions.
The main purpose of the proposed National Smart Grids Plan is to update the development plans set within the Smart Grids Development Program in Slovenia (2012, 2014) taking into account current trends in the operation of electricity systems and experience gained in implementing projects in this field.
The aim of the Plan is to prepare a comprehensive network development program in Slovenia, which will take smart grid solutions into account and cover development at the distribution and transmission level and take their interdependence into account. The program will provide the basis for the development of the power system, which will enable:
- security of electricity supply,
- non-discriminatory connection of different consumers (electric vehicles, heat pumps…), production (diffuse sources) and those both (storage tanks, prosumers),
- maximum use of electricity infrastructure and minimal investment in the network,
- coordination of the operation of the distribution and transmission network,
- provision of services by network users for various stakeholders in the electricity system.
At the same time, the Plan will also propose a methodology for planning networks with smart grids, without which the introduction of new solutions is not possible. In addition to the Faculty of Electrical Engineering, University of Ljubljana, the Milan Vidmar Electrical Institute, the Faculty of Electrical Engineering, Computer Science and Informatics, University of Maribor, SODO and ELES are also participating in this project.
The European Union wants to reduce its greenhouse gas emissions by 20% by 2020 and to become a carbon-free society in the coming years. For such a plan to succeed, we need to increase the share of renewables in individual EU Member States, which is a major challenge given the current situation and the state of electricity networks in EU countries. Smart grids represent an upgrade of today’s concept of operation and planning of networks, which enables the connection of various consumers (electric vehicles, heat pumps…) and production (renewable sources) in a technically appropriate and economically optimal way.
In the future knowledge of smart grid technologies will be one among the key skills in the field of power system operation.
The purpose of the project is to educate a new generation of researchers and engineers who will gain knowledge for the design and development of new technologies, which will help solving problems in the flow of electricity. Through various workshops, the partners will connect with the local industry. As part of the Smagrinet project, a five-day seminar will be held at the Faculty of Electrical Engineering, and it will be completed by students with a seminar paper. Students will learn about 10 current topics in the field of smart grids:
- consumers, resources and prosumers,
- integration of renewable sources into networks,
- operation of the distribution network with renewable sources,
- the impact of electric vehicles on the distribution network,
- use of electricity storage devices,
- algorithms for forecasting consumption and production,
- distribution network management with the help of smart grid technologies,
- the concept of a virtual power plant,
- quality of electricity in distribution networks with renewable sources and
- distribution network planning.
In addition to the Faculty of Electrical Engineering of the University of Ljubljana, eight other partners from six European Union countries are actively participating in the Smagrinet project. The two-year project, funded by the European Union under Horizon 2020, has € 2 million in funding.

Smart grid simulation platform
Until now, electricity companies in Slovenia have developed and tested smart grids only to a limited extent within the framework of pilot projects financed from various regulatory incentives, European funds or bilateral partnerships. However, such an approach to the expansion of smart grids will not be enough to accelerate the green transformation of the Slovenian energy sector and maintain the reliability of the operation of the Slovenian electricity system in the future. Changes will be needed to the existing treatment of smart grid investments, supplier-customer relations, market functioning and regulation. These changes will require a great deal of commitment and go beyond the traditional relations between electricity companies and customers.
The Smart grid project is one of the main projects of the Consortium for Green Transformation of Slovenian Energy, founded by ELES and GEN-I, and the consortium also includes distribution companies and the Faculty of Electrical Engineering, University of Ljubljana. The main result of the study will be a methodology for simulating the operation of distribution networks involving new consumers (electric cars, heat pumps…) and for a modern network planning process that allows comparing solutions of the existing planning approach (network reinforcement) with smart grid solutions involving increasing network awareness and manageability. Increasing manageability is based in particular on increasing user flexibility (adjusting consumption or production). The simulation platform will be designed in one of the classic software packages (eg Matlab, Python) and will use one of the programs for calculating power flows (eg Digsilent PowerFactory, OpenDSS).
The simulation platform will enable the simulation of operation and planning of a smart distribution network with the following objectives:
- power supply,
- non-discriminatory connection of different consumers (EV, heat pumps), production (RV) and those both (storage tanks, prosumers),
- maximum use of electricity infrastructure and minimal investment in the network,
- enabling the development of a methodology for optimal network development planning.
The study will be designed in two phases:
- The first phase will include simulations of the operation of sample low-voltage networks selected by distributors. Simulation examples will include simulations of the current situation and simulations of the situation in 2030 according to national plans in the field of energy. Based on the identified operating constraints in 2030, two scenarios of network development will be designed, ie the classic method of development that takes into account network reinforcements and development taking into account smart network solutions. The results will enable a critical evaluation of the proposed approaches and a practical insight into the issue from the point of view of electricity distribution companies.
- In the second phase, based on the results of the first phase, the theoretical basis of the simulation platform and methodology for network design will be designed.
Laboratory for Electrical Networks and Devices (LEND) is actively participating in the three-year OneNet project, funded by the European Union through scheme Horizon 2020, in the amount of almost 22 million euros. Project involves 72 partners from 22 countries.
OneNet aims at performing this critical step creating the conditions for a new generation of grid services able to fully exploit demand response, storage and distributed generation while creating fair, transparent and open conditions for the consumer. As result, while creating one network of Europe, the project aims to build a customer centric approach to grid operation. This ambitious view is achieved by proposing new markets, products and services and by creating a unique IT architecture.
While a single platform for Europe is not thinkable, OneNet proposes innovative mechanisms of platform federation which are the key technical enablers for the proposed vision. The project has also very ambitious exploitation goals aiming at creating consensus on the solution far beyond the limits of the consortium partners thanks to a variety of actions including a large-scale forum for discussion within the international energy community.
The main contribution of LEND will be within two tasks. Within first task LEND will be involved in investigation of new flexibility services in relation to the constraints in the distribution grid that may limit the available flexibility of network users. Within second task LEND will contribute in development of new innovative services and evaluation of results.
