Join SUBNET at WindPower 2010! SUBNET is a featured presenter at the upcoming wind industry conference. Attend the SUBNET presentation where a paper will be discussing how E.On has implemented a solution to calculate the power lost due to curtailment for ERCOT. While at the event, stop by booth #1629 and see some of the latest SUBNET technology.
Presentation Abstract
E.On is a wind power producer operating under ERCOT. Due to inaccurate wind power forecasts and grid reliability constraints, limits are imposed on the amount of wind power allowed onto the grid. Transmission line limits also require ERCOT to curtail specific wind turbines to avoid overloading. Both reliability constraints and transmission constraints force ERCOT to limit the amount of wind power companies like E.On can produce.
ERCOT has implemented a new initiative to gather information about how much wind power is being curtailed throughout their region. By gaining a more accurate understanding of how much wind power is limited, ERCOT can plan new transmission lines and provide better clarity on grid reliability in areas with high penetration levels of wind power.
To determine the amount of power curtailed, a current potential wind power estimate, based on the wind speed and the specific wind turbine power curve, must be calculated. Wind speed information is gathered from meteorological towers and/or turbine manufacturer’s readings at wind farms. The various, non linear wind turbine power curves are modeled using a logical application. Wind speed is inputted to these modeled power curves, and
the potential wind power available is calculated.Once this power estimate is known, wind power producers such as E.On, can calculate the power lost due to curtailment for ERCOT by calculating the difference between the available power and the current curtailment limit. This paper describes the solution implemented by E.On to gather curtailed wind power data for ERCOT.
