Renewable Energy in Hong Kong

Both solar power and wind power are intermittent renewable power sources, and their stochastic features are highly location dependent. To study renewable power generations in Hong Kong, we acquire meteorological data from the Hong Kong Observatory. The data include the hourly solar radiation in Kings Park (KP) of Hong Kong, and hourly wind speed at seven different locations of Hong Kong, as shown in the map.

Locations of Meteorological Stations as shown on the left (click to enlarge) include King’s Park (KP), Tai Mei Tuk (TMT), Sha Tin (SHA), Sai Kung (SKG), Tate’s Cairn (TC), Tai Po Kau (TPK), and Waglan Island (WGL).

You can download the processed scenario data at the end of this page, with details in the following papers:

Solar & Wind Power Productions

Based on the solar power model and wind power model, we calculate the daily (24 hours) realization of hourly solar and wind power productions in 365 days based on the measurement of data of solar radiation and wind speed (from Sep. 1 2012 to Aug. 31 2013). We set the number of preserved scenarios as 10 applied the forward scenario reduction algorithm to generate a scenario subset that best approximates the original scenarios (as shown in the following figure, click to enlarge), and obtained the corresponding probability of each scenario. Details can be found in our IEEE SmartGridComm 2014 paper and the corresponding technical report.

Data and Publication

Accoding to the legal requirement of Hong Kong Observatory, we have processed the raw data, and now release the hourly based scenario data to the research community. For each location, you will find the power generation data for 24 hours in each scneario, and the probabilities corresponding to 10 scnearios.

We hope that the data is useful for your research, and we would appreciate if you can cite the following publications when using our provided data.
