Optimisation of Wind Energy O&M Decision Making Under Uncertainty

Lead Research Organisation: University of Strathclyde
Department Name: Electronic and Electrical Engineering

Abstract

Wind energy will play a full part in decarbonisation of the future energy mix - if the costs can be reduced. This project develops a technological concept that helps achieve that cost reduction, by utilising data in a way which directly supports quick and reliable decision making in the everyday operation of a wind farm, either on- or offshore. The volume of data available from wind turbine assets is staggering - from component temperature traces, to weather forecasts, to sea conditions. But ultimately that data needs to be used by a control room engineer to change a decision in order to be useful. This innovative project develops a decision-making system that combines advanced visualisation methods and component health systems developed by UK SMEs with decision-theory from academia, and brings this together in a way that a wind farm operator can utilise to drive down the cost of operating a wind farm.

Description We have developed a decision making methodology which takes uncertainty and temporal dependency & structure into account. Our illustrative example is a wind turbine blade replacement decision - windy sites in the UK & elsewhere rarely drop below the crane lifting limit for blades (winds of 7 metres per second or below are needed to lift a blade). The key uncertainty here is the 1 week weather forecast, which the decision is based around. Currently there is no method to directly translate weather forecast uncertainty into the key decision (what day to hire crane and perform lift) - this decision would today be made deterministically (that is to say, not taking uncertainty into account). Our developed decision making methodology has shown that by taking uncertainty into account, it is possible to reduce cost and risk when making key decisions such as this. This key finding is being disseminated throughout the wind industry and will form the basis of future higher TRL work.

The ideas have been built on in the follow on project ORACLES (https://oracles.eee.strath.ac.uk/). THis has developed some of the concepts tested in this grant and applied them to a new application (offshore wind access forecasting).
Exploitation Route The methodology for structuring similar decisions under uncertainty will be published in an upcoming journal paper (IEEE transactions on engineering management). In principle this model applies to any decision under uncertainty. The next logical step is application to operational decisions when considering wind turbine condition monitoring data feeds and uncertainty regarding remaining useful life, accuracy of prognostic algorithms.

We are in the process of making our code publically available on a platform that will support all future forecasting and decision support models developed by our research team.

Description This methodology was built upon in the ORACLES supergen wind project (2019) which was then fpollowed by a live demo project at Teesside (2021-22) funded by EdF (https://www.edfenergy.com/for-home/energywise/research-development-safe-vessels-renewables). Edf estimate the annual cost savings could sum to £1m per annum per wind farm.
