Weather Bureau and Energy Bureau Put Forth Wind/Solar Power Forecast System

published: 2018-08-01 13:24

With weather conditions being a critical factor for wind and PV power, in terms of power output and site selection, the Central Weather Bureau and the Bureau of Energy, under the Ministry of Economic Affairs, have joined hands in putting forth a pilot version of " Meteorological-Information Based Green Energy Operations Center," for use by operators.

The pilot system is a fruit of the four-year "plan for application of weather information in the development of green energy" starting 2017, overseen by the two units, calling for development of technologies for analysis and forecast of weather conditions for wind and PV power, as well as weather-information application products, tailored to the different needs of operators in the upstream, middle, and downstream sectors of the industrial chain.

Webpage of the pilot system, an initial fruit of the plan, shows data on historical average of wind power at altitude of 100 meters and solar energy on ground, plus monitoring and analytical data and weather forecast data.

Lin Hsi-min, director of the technology center of Central Weather Bureau, pointed out that information on the analysis of the density and output forecast of green power has been available, as reference for operators in site selection, in addition to forecast for power output hourly in the next three days or once every six hours in the next seven days, facilitating power deployment and provision of value-added smart-grid services by state-run Taiwan Power Company.

The pilot system shows that the most suitable sites for the development of PV power in Taiwan are coastal areas of Tainan, Yunlin, and Chiayi, while those for wind power are offshore areas of Miaoli, Taichung, Changhua, and Eluanbi of Pingtung.

Yen Chueh-cheng, senior researcher at the Industrial Technology Research Institute (ITRI), reported that the website's offshore wind power system, still under construction, will offer forecast for power output of offshore wind farms, as well as system for the dispatch and tracking of wind-turbine installation vessels, which, in combination with data on weather, sea state, and shipping, can be used as reference in engineering decision making, leading to cost reduction.

The Central Weather Bureau noted that it will continue improving the capability for weather forecast and developing different forecast methods and integrated technologies, installing an application system more akin to industrial needs.
