最近,丹麥技術大學 (DTU) 的研究人員宣告他們已首創將量子計算應用於能源系統潮流建模。
在該項目中,DTU風能和能源系統系研究人員的工作重點是探索當前量子計算在能源系統潮流研究中的潜力。DTU研究人員錶示,雖然他們早前已經提出了量子功率流算法,但這些算法僅用於模擬而並未在真實的量子計算機上進行測試。
現在,DTU研究人員將他們創建的基於“快速解耦潮流”方法的新算法,在五臺不同的IBM量子計算機上進行了測試,其中包括四種公開可用的系統以及另一臺更大的量子系統。其目的是為了驗證計算結果以及評估該方法的擴展性。
DTU研究人員錶示,在所有測試情况下,量子功率流都收斂到與經典方法相同的解,並且由於當前量子硬件中存在噪聲影響,與經典收斂的5次相比,新算法需要超過30次迭代。此外,由於更大的量子計算系統受噪聲的影響擴大,迭代次數也隨之增加。
DTU研究人員指出:“我們已經證明,當前的量子硬件能够為小型測試系統執行功率流,但可擴展性仍然是當前主要問題之一。”
受此結果的鼓舞,研究人員將開展研究:基於量子計算機對可再生能源系統(包括間歇性風能和太陽能光伏發電)的電網穩定性進行實時分析。同時,他們還將探索尋找量子計算和經典計算在能源系統中的最佳應用方案。
該項目計算負責人Brynjar Sævarsson說:“未來,隨著量子計算機的大力推動,我們將重塑電力系統的計算方式。量子計算機具有解决難題的潜力,這意味著我們將開發出基於可再生能源的電力系統所需的安全穩定的工具,我們現在正著手開展這項工作。”
