Highlights
- Provides an accurate steady-state and dynamic behaviour analysis of power systems for large-scale wind farms under different operating conditions
- Suited for use in modelling large-scale wind farms and reduces the overall computational burden on the control system
- Uses weighted dynamics to quantify the contribution of each Wind Turbine Generator (WTG) in a large-scale wind farm
Opportunity
A research team from the University of Alberta has developed an aggregation method to model a large-scale wind farm comprising multiple WTGs using a single equivalent WTG unit. The equivalent WTG unit provides the same mechanical wind turbine and electrical generator power output as the combined multiple WTGs. The equivalent WTG unit is derived through one-time analysis, thus effectively reducing the computational burden and model complexity associated with existing aggregation models. Unlike existing models, the proposed method is adaptable to wind farms having diverse WTG parameters and varying wind speed zones.
Competitive advantage
- Computationally efficient at modelling large-scale wind farms
- Reduced computational burden of steady-state and dynamic analysis
- Accurately describes wind farm behaviour regardless of wind speed variation between zones and/or different WTG parameters
Status
- Patent pending - US 2020/0401740
