摘　　要：动态规划方法在天然气管网动态运行优化求解中存在"维数灾难"和"无后效性"问题,求解效率较低.为了提高动态规划方法在天然气管网动态运行优化求解中的效率,对管网动态运行优化的数学模型作了相关分析,在此基础上提出了时间层独立化处理方法,将多时间层的优化问题转变成独立的单时间层的优化问题,然后采用自适应动态规划方法进行求解.仿真结果表明:时间层独立化处理方法能有效避免"维数灾难"和"无后效性"问题,简化了求解过程,较大的提高动态规划方法对管网动态运行优化问题的求解效率.The dynamic programming method is inefficient at solving the natural gas network transient state optimal problems known as the curse of dimensionality and the non-aftereffect property. To improve the solving efficiency, dynamic optimization mathematic models are analyzed, and a type of time-layers independent approach is proposed. The multiple time-layers transient state optimal problems could be transformed into a series of independent, single time-layer optimal problems. The adaptive dynamic programming method is applied to obtaining the optimum solution. The simulation results show that the suggested approach, which avoids the curse of dimensionality and non-aftereffect property, simplifies the solution process and improves the solving efficiency.
