  • The importance of wind forecasting
    With the recent and continued increase in wind power, the challenge is clear: how can the energy industry integrate this intermittent power source into the electricity grid? Jeff Lerner, Michael Grundmeyer and Matt Garvert of 3TIER make the case for better forecasting.


IBM tech improves wind reliability

IBM has developed power and weather modelling technology that could help utilities increase the reliability of renewable energy resources.

Hybrid Renewable Energy Forecasting (HyRef) technology uses weather modelling capabilities, advanced cloud imaging technology and sky-facing cameras to track cloud movements, while sensors on the turbines monitor wind speed, temperature and direction. When combined with analytics technology, the data-assimilation based solution can produce accurate local weather forecasts within a wind farm as far as one month in advance, or in 15-minute increments.

By using local weather forecasts, IBM's HyRef can predict the performance of each individual wind turbine and estimate the amount of generated renewable energy. This could allow utilities to better manage the variable nature of wind and solar, and more accurately forecast the amount of power that can be redirected into the power grid or stored. It will also allow energy organizations to easily integrate other conventional sources such as coal and natural gas.

"Utilities around the world are employing a host of strategies to integrate new renewable energy resources into their operating systems in order to reach a baseline goal of a 25 per cent renewable energy mix globally by 2025," said Vice Admiral Dennis McGinn, president and CEO of the American Council On Renewable Energy (ACORE). "The weather modelling and forecasting data generated from HyRef will significantly improve this process and in turn, put us one step closer to maximizing the full potential of renewable resources."

State Grid Jibei Electricity Power Company Limited (SG-JBEPC), a subsidiary company of the State Grid Corporation of China (SGCC), is using HyRef to integrate renewable energy into the grid. This initiative led by SG-JBEPC is phase one of the Zhangbei 670MW demonstration project, the world's largest renewable energy initiative that combines wind and solar power, energy storage and transmission. This project contributes to China's 5-year plan to reduce its reliance on fossil fuels.

By using the IBM wind forecasting technology, phase one of the Zhangbei project aims to increase the integration of renewable power generation by 10 per cent. This amount of additional energy could power roughly more than 14,000 homes.
