Power Systems Modelling

Power systems modelling is the representation of power systems or electrical networks in a simulation model reflecting their behavior in the real world under different operating conditions - typically performed using specialised power systems modelling software.

What is Power Systems Modelling?

Composite Model | Power Systems Modelling | PulseTech

In the modern power grid, power electronics equipment plays a crucial role in ensuring efficient and reliable power conversion and transmission. However, the complexity of these devices can make it challenging to predict their behaviour and impact on the power system, especially in remote areas where the power system is often the weakest.

In this case, power systems modelling of power electronics equipment can be effectively utilised in power system studies to understand the impact of power electronic installations on the grid. 

Our specialist team uses industry-leading software and cutting-edge techniques to develop detailed models that accurately represent your power electronics equipment. With our modelling services, you can identify potential issues, improve system performance, and ensure compliance with grid codes and regulations. Contact us to learn more about our power electronics equipment modelling services today.

By using power systems modelling of power electronics equipment, a deeper understanding of how power electronic devices will interact with the power grid can be gained, potential disturbances to the grid can be identified, and allocation of power for the system can be optimised to ensure maximum efficiency and reliability. Some examples of its utilisation include:

  • Design of new power systems

  • Analysis of system stability and reliability

  • Optimisation of system operation

  • Assessment of the impact of new technologies and equipment on the system
