1、華北電力大學(xué)（保定）碩士學(xué)位論文基于網(wǎng)格的電力系統(tǒng)并行計算的研究姓名：柳洋申請學(xué)位級別：碩士專業(yè)：計算機(jī)應(yīng)用技術(shù)指導(dǎo)教師：鄭顧平20081228華北電力人學(xué)碩士學(xué)位論文摘要摘要目前，電力系統(tǒng)的運(yùn)行與控制已經(jīng)演變成一個涉及大量數(shù)據(jù)和信息計算的應(yīng)用工程。因此，有必要將網(wǎng)格計算技術(shù)引入到電力系統(tǒng)的工程實踐中來，探索在大電網(wǎng)范圍內(nèi)實施高效率控制和決策的新途徑。本文設(shè)計了一種基于網(wǎng)格的潮流計算架構(gòu)，提出了一種基于多QoS約束的網(wǎng)格選擇調(diào)度算法。同

2、時，論文中設(shè)計了求解潮流計算矩陣方程的并行算法，提出了冗余計算的方案，并將算法編制成網(wǎng)格服務(wù)，部署在Globus網(wǎng)格計算結(jié)點(diǎn)上。通過在實驗室節(jié)點(diǎn)上對平臺進(jìn)行的功能性測試，結(jié)果顯示，基于Globus網(wǎng)格平臺設(shè)計的潮流并行計算系統(tǒng)具有潛在的并行優(yōu)勢和廣泛的應(yīng)用前景。關(guān)鍵詞：網(wǎng)格計算，任務(wù)調(diào)度，Globus，潮流計算ABSTRACTAtpresent，theoperationandcontrolofelectricpowersystemhav
