1、多電源電力系統(tǒng)多目標(biāo)優(yōu)化調(diào)度研究摘要隨著人們生活水平的提高，人們用電量逐漸增加，而工業(yè)的快速發(fā)展則加劇了用電需求與電力供應(yīng)之間的矛盾。我國(guó)以火力發(fā)電為主體的發(fā)電模式，存在環(huán)境污染及能源供不應(yīng)求等諸多問(wèn)題，因此如何合理利用現(xiàn)有的發(fā)電能源，在減少煤炭能源消耗的同時(shí)降低氮氧化物的排放量具有極其重要的現(xiàn)實(shí)意義。我國(guó)發(fā)電模式在不斷發(fā)展過(guò)程中已由簡(jiǎn)單模式逐漸轉(zhuǎn)為復(fù)雜，其發(fā)電形式主要由水電、火電、風(fēng)電和核電組成。本文從水電能源、火電能源、風(fēng)電能源和核電資源的運(yùn)行特性及輸出功率特性著手，以水電站的出力最大、火電廠的氮氧化物排放量和煤耗量最少為目標(biāo)建立多目標(biāo)優(yōu)化模型，對(duì)含有風(fēng)電場(chǎng)
2、的多電源電力系統(tǒng)進(jìn)行優(yōu)化調(diào)度研究。針對(duì)含有風(fēng)電場(chǎng)的多電源電力系統(tǒng)多目標(biāo)優(yōu)化調(diào)度問(wèn)題，本文采用加權(quán)法進(jìn)行模型的轉(zhuǎn)換，應(yīng)用層次分析法權(quán)衡多目標(biāo)之間的權(quán)重，選用自適應(yīng)粒子群算法對(duì)模型進(jìn)行求解。以一個(gè)含有100臺(tái)風(fēng)電機(jī)組構(gòu)成的風(fēng)電場(chǎng)、4個(gè)水電站、10個(gè)火電廠和1個(gè)核電站構(gòu)成的多電源電力系統(tǒng)為例進(jìn)行算例分析，得出各種電源的機(jī)組出力、火電機(jī)組的氮氧化物排放量及耗用的煤炭總量，并對(duì)所得結(jié)果進(jìn)行分析總結(jié)，證明了模型的正確性和可行性。關(guān)鍵詞：多電源電力系統(tǒng)改進(jìn)自適應(yīng)粒子群層次分析法多目標(biāo)優(yōu)化THEMULTI．OBJECTIVEOPTIMIZATIONSCHEDULINGOFSYS
