Integrated condition-based maintenance modelling and optimisation for offshore wind farms (2021)
Journal Article
Dao, C. D., Kazemtabrizi, B., Crabtree, C. J., & Tavner, P. J. (2021). Integrated condition-based maintenance modelling and optimisation for offshore wind farms. Wind Energy, 24(11), 1180-1198. https://doi.org/10.1002/we.2625

Maintenance is essential in keeping wind energy assets operating efficiently. With the development of advanced condition monitoring, diagnostics and prognostics, condition‐based maintenance has attracted much attention in the offshore wind industry i...

Operational Planning and Optimisation in Active Distribution Networks using Modern Intelligent Power Flow Controllers (2017)
Presentation / Conference Contribution
Ibrahim, A., Kazemtabrizi, B., & Dent, C. (2017). Operational Planning and Optimisation in Active Distribution Networks using Modern Intelligent Power Flow Controllers. In 2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe). https://doi.org/10.1109/isgteurope.2016.7856196

In this paper, a centralised control framework is introduced for day-ahead operational planning of active distribution networks which accommodate high levels of distributed generation resources. The purpose of the framework is to plan network operati... Read More about Operational Planning and Optimisation in Active Distribution Networks using Modern Intelligent Power Flow Controllers.

Analysis of Two Onshore Wind Farms with a Dynamic Farm Controller (2015)
Presentation / Conference Contribution
Ahmad, T., Girard, N., Kazemtabrizi, B., & Matthews, P. (2015). Analysis of Two Onshore Wind Farms with a Dynamic Farm Controller.

This work develops an assessment methodology for identifying potential areas where coordinated control can increase farm power output. A dynamic farm controller is presented that exploits the benefits of reducing power of the upstream turbines for in...

Dynamic Wind Farm Controller (2015)
Presentation / Conference Contribution
Ahmad, T., Matthews, P., Kazemtabrizi, B., & Smith, C. (2015). Dynamic Wind Farm Controller.

This work presents a dynamic wind farm controller for maximising power output of a wind farm. The controller uses a coordinated control approach where the output of the upstream turbines is varied to minimise wake effects on the downstream turbines.... Read More about Dynamic Wind Farm Controller.

Modelling and Evaluation of Wind Speed Time Series for Reliability Analysis of Offshore Wind Farms (2014)
Presentation / Conference Contribution
Smith, C., Crabtree, C., Matthews, P., & Kazemtabrizi, B. (2014). Modelling and Evaluation of Wind Speed Time Series for Reliability Analysis of Offshore Wind Farms.

This paper outlines proposed testing criteria for wind speed time series (WSTS) models. The objective is to assess their suitability for reliability analysis that is dependent on an accurate representation of weather patterns. Two WSTS models were an...

Determining the Wind Speed Distribution within a Wind Farm considering Site Wind Characteristics and Wake Effects (2014)
Presentation / Conference Contribution
Ahmad, T., Smith, C., Matthews, P., Crabtree, C., & Kazemtabrizi, B. (2014). Determining the Wind Speed Distribution within a Wind Farm considering Site Wind Characteristics and Wake Effects.

This paper introduces a wind speed model for simulating the distribution of wind speeds within a wind farm. The model combines a macro scale wind speed time series (WSTS) model based on a continuous Markov process with a wake flow model, based on the...
