Small Scale Wind Farm
|
The small scale Myres hill site was chosen as it is co-located with Whitelee windfarm just south of the city of Glasgow, Scotland. As such, the meteorological wind speed data was applicable for both sites which saved time and resources. The site contains two 950 kW NEG Micon NM54/950 turbines. The full output of the turbines would be suitable to supply 300 households (small community) and was ideal to simulate proposed integrated storage solutions at this scale. As a research facility, Ofgem power output data and turbine specification data was also readily available for analysis and verification purposes with over a decades worth of data available. Further, it was also possible to compare the simulation to other operational sites of similar size. |

Large Scale Wind Farm

Whitelee wind farm is the UK's largest onshore site and is the second largest in Europe. It is commercially operated by Scottish Power and with 215 turbines is rated to provide power for 300 000 homes which is the approximate number in the city of Glasgow. The site is located on Eaglesham Moor to the south of the city of Glasgow, Scotland. This is approximately 20 minutes travel from the University of Strathclyde.
The large scale Whitelee site was chosen as it was ideal to simulate proposed integrated storage solutions at high output city scale in accordance with the aim and objectives. This, in combination with the fact that the output is regularly curtailed due to the non dispatchable nature of the site in accordance with supply and demand matching of the grid. As whitelee has been fully operational with 215 turbines since 2013, Ofgem power output data and turbine specification data was also readily available for analysis and verification purposes. This facilitated the validation of calculated and simulated power output results and enabled the simulation of optimised systems. |
Capacity Factors
|
Capacity factor of a wind farm is the total measured output over the maximum capacity output.
The average capacity factor for a windfarm is:
The average capacity factor published by Ofgem for Whitelee windfarm is only 18.56% for December 2016 - November 2017 and for the test site at Myres Hill a capacity factor of 19.04% was calculated. It is expected that these values of capacity factor are inaccurate due to curtailed wind energy. Whitelee is situated in a very windy area of the UK and therefore it is unlikely the output would be below the UK average. Capacity factor becomes a misrepresentation of windfarm performance during periods of curtailment as no mitigation factor is applied for realistic potential output. |
