Inertia Requirements for Renewable Power Systems
The increasing penetration of renewable energy sources and the replacement of fossil-fuel based power plants is changing the dynamics and stability of today’s electrical power systems. The substitution of well-known synchronous machines with power-electronic interfaced generation presents a challenge, particularly with respect to frequency behaviour.
This online course focuses on frequency and inertia issues and how to approach them using dynamic power system models that are based on open-source software. However, it is noted that replacing synchronous machines with non-rotational sources also has more general consequences.
The topics covered are:
- The Concepts of Power System Stability and Control
- The importance of Inertia in Renewable Power Systems
- Dynamic Power System Modelling (for experts)
- Case Study (for experts)
- Lessons learned

Upon completion of this course, you should be able to:
- Understand the wider context of inertia’s importance to power system stability.
- Distinguish the different timescales for frequency control.
- Differentiate between conventional and renewable power plants, in terms of their control behaviour.
- Identify and determine relevant dynamic stability measures.
- Recognise the different standards for frequency stability in different countries.
- Define inertia (in the context of conventional power plants).
- Illustrate renewable power system challenges, with respect to inertia.
- Explain how decreasing inertia changes the frequency gradient.
- Define measures to increase power system inertia, with or without storage solutions.
- Operate a software framework for modelling the dynamic stability of power grids, in order to investigate the necessary amount of inertia in relevant power systems.
- Analyse a case study in the open-source software, PowerDynamics.jl, in order to evaluate different solutions to increase inertia.
- Identify measures for wind and PV generation, which will ensure that inertia does not become a limiting factor in integrating variable renewable energies.
- Flexibility to study at any time and from any location
- Extensive support
- Multimedia learning material and self-evaluation tests
- RENAC certificate upon successful finalisation of the training
