The artificial neural net ( ann ) way is universal regard as one of the most effective ways of stlf . in this paper , some research is developed for stlf using ann ways in several parts : the first part is about the arithmetic of ann based on bp model , namely the advanced of traditional bp arithmetic , one alterable step and scale bp arithmetic based on comparability of model and probability of accepting bp arithmetic is used to enhances a lot the convergence rate of learning process of bp network , but also avoid the stagnation problem to some extent . it indicates that the ann ' s efficiency and precision by the way can be ameliorated by the simulation of real data 神經網絡方法在短期預測中已經被公認為較有效的方法,本文針對神經網絡用于電力系統短期負荷預測的幾個方面展開研究工作:第一部分研究一般用于負荷預測的神經網絡bp模型的算法,即對傳統的bp算法的改進,將一種基于模式逼近度和接受概率的變步長快速bp算法應用到短期負荷預測,仿真結果表明該方法有效的改善了bp算法收斂速度慢以及容易陷入局部最小點的缺點,從而提高了神經網絡用于負荷預測的效率和精度。
