【摘要】：動(dòng)態(tài)規(guī)劃方法在天然氣管網(wǎng)動(dòng)態(tài)運(yùn)行優(yōu)化求解中存在"維數(shù)災(zāi)難"和"無后效性"問題,求解效率較低.為了提高動(dòng)態(tài)規(guī)劃方法在天然氣管網(wǎng)動(dòng)態(tài)運(yùn)行優(yōu)化求解中的效率,對(duì)管網(wǎng)動(dòng)態(tài)運(yùn)行優(yōu)化的數(shù)學(xué)模型作了相關(guān)分析,在此基礎(chǔ)上提出了時(shí)間層獨(dú)立化處理方法,將多時(shí)間層的優(yōu)化問題轉(zhuǎn)變成獨(dú)立的單時(shí)間層的優(yōu)化問題,然后采用自適應(yīng)動(dòng)態(tài)規(guī)劃方法進(jìn)行求解.仿真結(jié)果表明:時(shí)間層獨(dú)立化處理方法能有效避免"維數(shù)災(zāi)難"和"無后效性"問題,簡(jiǎn)化了求解過程,較大的提高動(dòng)態(tài)規(guī)劃方法對(duì)管網(wǎng)動(dòng)態(tài)運(yùn)行優(yōu)化問題的求解效率.
[Abstract]:The dynamic programming method has the problems of "dimension disaster" and "no aftereffect" in solving the dynamic operation optimization of natural gas pipeline network, and the efficiency of the solution is low. In order to improve the efficiency of dynamic programming method in solving dynamic operation optimization of natural gas pipeline network, the mathematical model of dynamic operation optimization of natural gas pipeline network is analyzed. On this basis, the independent treatment method of time layer is put forward, and the optimization problem of multi-time layer is transformed into an independent single time layer optimization problem, and then the adaptive dynamic programming method is used to solve the problem. The simulation results show that the time layer independence treatment method can effectively avoid the problem of "dimension disaster" and "no aftereffect", simplify the solving process, and greatly improve the efficiency of dynamic programming method in solving the dynamic operation optimization problem of pipe network.
