Zurich, Switzerland · Taipei, Taiwan
Researcher in energy system analysis and energy storage, previously at the University of Birmingham and the University of Exeter in the UK. Research topics include energy system modelling, harmonising energy data with ontologies, and using large language models to speed up data processing. This site is a personal project to make Taiwan's energy transition easier to explore with open data and open models. 能源系統分析與儲能研究者，曾任職於英國伯明罕大學與艾希特大學。研究領域包括能源系統建模、以本體論整合能源資料，以及運用大型語言模型加速資料處理。本網站是個人計畫，希望以開放資料與開放模型，讓台灣的能源轉型更容易被探索。
What this site is本網站是什麼
A model of Taiwan's electricity system built with PyPSA-Earth, an open-source energy system model. It takes Taiwan's power plants (from Taipower's own unit list), the transmission grid (from OpenStreetMap), hourly weather (ERA5) and demand, and finds the lowest-cost way to run the system for every 4-hour step of a year. The results, the inputs and every data source are published here. 以開源能源系統模型 PyPSA-Earth 建置的台灣電力系統模型。模型使用台灣的電廠（取自台電機組清單）、輸電網路（取自 OpenStreetMap）、逐時氣象（ERA5）與需求，計算一整年中每 4 小時最低成本的系統運轉方式。結果、輸入資料與所有資料來源都公開在本網站。
What it can and cannot tell you能與不能回答的問題
- Good for: comparing options, e.g. whether more offshore wind or a nuclear restart cuts more CO₂, or where the grid limits supply.適合：比較方案，例如增加離岸風電或重啟核電哪個減碳較多，或電網在哪裡限制供電。
- Not a forecast: 6 regions instead of the real grid, 4-hour time steps, a few weather years, and costs from international projections in euros.不是預測：以 6 個區域代表實際電網、每 4 小時一個時段、少數幾個氣象年，成本採國際預估值（歐元）。
- Not official: this is independent research, not a product of Taipower or any government agency. Official figures are quoted with their sources.非官方：這是獨立研究，並非台電或任何政府機關的產品。引用的官方數據皆註明來源。
