摘要
为解决传统动态最优潮流(DOPF)算法中计算速度和计算精度之间的矛盾,建立了电力系统DOPF的变分模型,推导了该变分模型的最优性条件。在此基础上提出了一种基于Radau配置法的DOPF求解新算法。该算法具有计算量小、计算精度高等特点。对某实际系统的分析结果表明算法能够满足在线运行的需求。
To solve the conflict between calculating speed and accuracy in conventional dynamic optimal power flow （DOPF） algorithms, a variation model of .DOPF is developed and the optimal condition for the model proposed is derived. A new algorithm based on the Radau collocation method for solving the DOPF is proposed, which has such advantages as high efficiency and accuracy. The numerical test on an actual system shows that the new algorithm can meet the requirement of online dispatch of the power system.
