Abstract. Wind farm flow control (WFFC) is a topic of interest at several research institutes and industry certification agencies worldwide. For reliable performance assessment the technology, efficiency capability models applied to WFFC should be carefully evaluated. To address that, FarmConners consortium has launched common benchmark for code comparison under controlled operation demonstrate its potential benefits, such as increased power production. The builds on available data sets from...
Improving offshore wind turbine reliability is a key industry goal to improve the availability of this renewable energy generation source. The semiconductor devices in power converter are traditionally considered as most sensitive and important components achieve managing their thermomechanical stressing vital, since one principal long-term aging mechanisms. Conventional deterministic prediction methods used industrial applications not suitable for applications, due stochastic nature speed....

A novel approach to proposed that provides full flexibility both. It consists a controller architecture an interface individual The design specific realisation the interface, Power Adjusting Controller, presented requires little information on turbine dynamics or does not compromise turbine's safety.

Abstract. Wind direction variability significantly affects the performance and lifetime of wind turbines farms. Accurately modelling understanding effects yaw misalignment are critical towards designing better turbine farm flow controllers. This review focuses on control-oriented variability, which is an approach that aims to capture dynamics for improving controller over a complete set scenarios, performing iterative development and/or achieving real-time closed-loop model-based feedback...
The quantity and size of wind farms continue to grow as countries around the world strive meet ambitious targets for renewable electricity generation such UK government's Net Zero target increasing offshore energy from current levels (circa 6 GW) circa 75 GW by 2050. With farms, there is a growing requirement use farm level control both help with grid integration minimise loads on turbines in farm. In this paper, methodology distributing power set points through whilst meeting delta point...

Wave energy converters (WECs) come in many different forms, from point absorbers and oscillating water columns to bulge wave devices. This paper focuses on the control of absorber WECs, which typically have a narrow-banded frequency response and, therefore, is well placed improve capture such WECs. The acausal nature problem means that, theoretically optimal almost impossible achieve practice; however, velocity tracking (OVT) offers simple robust approximation that can better power than...

Genetic algorithms use the ideas of Darwinian evolutionary theory to find optimal solution a design problem. Here they are utilised in two scenarios. Firstly, finding power take-off (PTO) force for maximising electrical output device by accounting PTO efficiencies. The genetic algorithm finds marginally faster than brute forcing method with added benefit not being constrained discrete grid test points, hypothetically leading more accurate result. Secondly, these forces used another fit...
Abstract Wind farm flow control (WFFC) is an emerging technology involving coordinated operation of wind turbines within a to achieve collective goals. To design and evaluate controllers, models are used that capture the key aerodynamics system whilst remaining computationally efficient for iterative controller design. This review article reveals considerable heterogeneity in potential study WFFC. Lack consensus problematic as differences results from separate studies attributable both model...
A hierarchical Wind Farm Control (WFC) approach was previously developed that uses Power Adjusting Controllers (PACs) on each wind turbine in a farm. The PACs can be retrofitted to existing assets with no knowledge of, or change to, the full envelope controller (FEC). However, of aerodynamics is required and not usually directly available from Original Equipment Manufacturer (OEM), necessitating estimation. In this letter, estimated aerodynamic properties are obtained via scanning LIDAR...
