Comprehensive analysis of On-Load Tap Changers (OLTC) for voltage control and hosting capacity enhancement

We are offering a self-funded PhD position in the comprehensive analysis of On-Load Tap Changers (OLTC) for voltage control and hosting capacity enhancement with the Department of Electrical and Power Engineering. Applications are accepted on a rolling basis, so you can apply at any time.

If you have any questions about the project or would like to arrange an informal discussion, please reach out to Dr Ahmed F. Zobaa at ahmed.zobaa@brunel.ac.uk.

The project

This research aims to deliver a thorough investigation into the role of On-Load Tap Changers (OLTC) in improving voltage regulation and increasing hosting capacity in distribution systems.

By utilising advanced simulations and real-world data, the study will examine the deployment of OLTC technology across medium and low-voltage networks.

The integration of smart meters with OLTC systems will be explored to enhance real-time voltage control, improving grid resilience and distributed generation hosting.

The research will also provide a detailed cost-benefit analysis, balancing the operational and maintenance costs of OLTC against its significant benefits for grid stability and performance.
