Power generation is being integrated into the electricity grid. Increasingly more power is coming from Distributed Energy Resources (DER), such as solar and wind farms, instead of large power plants, which were previously the only source. The stability of the electricity grid is thus becoming dependent on the DER operators and the communication between grid operators and DER operators.

This change creates new cyber security risks. By attacking the DER operator’s infrastructure, grid stability can be disrupted, and through connected DER systems it might be possible to attack DSO and TSO systems. To ensure the secure operation of the electricity grid, the security of DER operators and their connection to the grid operators and market systems should be at a level that is in alignment with that of the grid operators, while considering the DER specific functional and operational context.

In 2020, ENCS has launched a cooperation with WindEurope and Solar Power Europe to define which measures DER and grid operators should take to sufficiently mitigate security risks to the electricity grid. The project concerns all systems needed by DER operators to ensure electricity delivery and connectivity with the grid operators, according to the schedules and agreements with the latter and regulatory compliance.

The project will produce the following deliverables:

  1. A risk assessment for DER security
  2. A set of recommended security measures for DER operators, covering both technical and organizational measures
  3. A set of recommended security measures for grid operators covering connectivity risks, including a recommended security architecture
  4. Set of procurement requirements for field devices used by the DER operator
  5. A position paper on DER security, providing context on the subject and the main project results
