Network Code for Operations

System operation Network code contains details about the requirements and principles of operational security, rules and responsibilities for the coordination and data exchange between TSO / DSO / significant grid users, and rules aiming to establish a common framework for frequency control and services. Specifically, the solution covers recommendations about emergency and restoration code, and system operations code. The recommendations to these codes can be implemented by investigating the new frequency control concept, system swing dynamics, requirements of minimum system inertia and the new voltage control concept.

Components & enablers

  • High RES integration in the new power systems
  • Harmonisation in common framework for all the power sectors members in EU
  • Enabling proper coordination between different participants in the grid

State of the art in application and research

In the RESERVE project, the regulatory requirements for the transition up to 100% RES is being studied through simulations. First, the new concept for frequency control is investigated by introducing New ICT architecture. Second, the requirements for minimum inertia are explored. For the faster and more accurate protection and automatization of the system, linearised wing equations are proposed. Finally, a new voltage control concept between DSO and prosumers is investigated, by considering new ICT requirements and inverters generation.

In the INTEGRID project, the role of DSOs is being investigated through the regulatory recommendation for the countries participate in the project.

In the AnyPlace project, regulatory recommendations regarding the deployment of smart metering platform will be proposed. Specifically, recommendations will mainly focus on energy, security and telecommunication standardisation. The recipients of this proposal are future projects, regulation and policies for EU citizens, utilities and grid operators, together with industry and market.

In the EU-SysFlex project, an assessment of the regulatory framework in the context of provision innovative system services is being made.

Technology Readiness Level


Current focus of R&D and research gaps

Currently, the RESERVE project is mainly striving to extract recommendations through simulations in the area of Network code operation. This is the only project entirely dedicated to making recommendations about the regulatory framework in the new era of power systems. Thus, there is a research gap in this area, specifically regarding investigating the rules and the responsibilities in the coordination and data exchange between different actors of the power system.
