Digitalisation and smart technologies for the power sector

A large part of the power sector is already affected by digitalisation. The more that generation shifts from centralised thermal systems to decentralised, renewable systems, the greater the potential application of modern, digital tools in system control. Digitalisation is the key technology that makes it possible to organise decentralised networks and thus contribute to decarbonisation while maintaining a high level of security of supply.

The integration costs of wind and solar power

Grid costs, balancing costs, plant utilisation, total costs, economic effects
 

When a new power plant is constructed, the developer expects to incur costs for planning, building and connecting the unit. However, integrating this unit into the existing power system bears additional costs related to delivering the produced energy to the consumer at the precise time it is needed. These costs together are summarised under the term integration cost.

Because power generation from wind and solar photovoltaic (PV) power plants depends on weather conditions and hence varies over time, the cost of integrating these units into a power system differs substantially from the integration cost of dispatchable power plants. Thus, understanding and being able to estimate the integration cost of variable renewable energy (VRE) (wind and solar PV) is key to determining total economic cost. This then allows for a welfare-optimal generation mix in the process of planning the transition to a decarbonised electricity system.

 

This course focuses on

  • Grid costs
  • Balancing power costs
  • Effects on existing power plant utilisation
  • Total system cost approach


Upon completion of this course, you should be able to

  • Explain the concept of integration cost, its purpose, definition and relevant points of discussion,

  • Based on literature estimates, specify the range of grid costs, balancing costs and economic effects on existing conventional power plant utilisation, and discuss possible reasons for variations in estimates,
  • Discuss the total system cost approach as an alternative for comparing integration cost in different scenarios and identify its strengths and limitations.


This training suits those who

  • Would like to get detailed insight in the economics of grid integration of wind and PV
  • Want to compare grid integration costs wit benchmark data
  • Need to develop grid integration strategies for photovoltaic and wind power

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 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

  • 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.
