INTERPRETER deliverable 2.1 has been released and presents existing and future issues affecting electricity grid management which the project is addressing.

This H2020 project is funded by the European Commission (GA No. 864360) and is made up of nine partners from Spain, Portugal, Greece, Denmark, Belgium and France.

This report is to provide an overview of the current problems encountered by DSO and TSO across Europe. It has been developed over 8 topics, developing for each one the regulatory context and the potential impacts to DSO (either as risks or as opportunities). These 8 topics were the following: renewable energy sources, flexibility, planning and operation, reliability and power quality, electricity markets, E-mobility, microgrids and energy communities, digitalization.

Europe as done a lot of work pushing the integration of Renewable Energy Sources as main energy sources. The Clean Energy package gives a target of 32% of the total Energy to be from renewable sources by 2030. And the global capacity within Europe is expected to grow from 124 GW in 2018 to 182 GW in 2024.

Flexibility may take 4 main sources: traditional controllable generators, demand response, RES curtailment and energy storage.

Planning and operation has gone through a fundamental transition from uni to bi-directional power flow.

Within the Electricity market, the liberalization has led to 2 main implications: a switching rate usually at maximum 12% over the years, and usually about 3 main suppliers for 70% of energy consumption.

Electrical vehicles are expected to grow to 128 million units by 2030 worldwide.

For power quality, three broad aspects define the quality of supply: continuity of supply, voltage quality, quality of services to consumers.

A growth in Energy communities, requiring in the future more communication and coordination between EC and DSO for their integration into the grid management.

The changes happening on the power market will impact strongly the way DSO operate their networks: from the increased penetration of renewable generation technologies, along with the increased energy efficiency pushed by EU regulation, to electrification of the transport sector… This will lead to a growth in the use of real-time metered data, power flow optimization, and electricity dispatch tools for a more accurate control of the grid.
