Course details

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.

This training suits those who:

Are involved in grid operation and grid planning with wind power and photovoltaic
Need to understand how inertia in the grid is changed by wind and photovoltaic development
Would like to operate a software to model dynamic stability of a model case power grids with wind power and photovoltaic
