模拟退火算法及其在短期负荷预测中应用

Application of simulated annealing algorithm to short-term load forecast

将模拟退火算法应用于短期负荷预测领域,其特点是模型简单、运算效率高,并具有较好的全局最优性能,从而很好地克服了传统BP算法容易陷入局部极小点的缺陷。该模型考虑温度和预测日类型,可进行工作日和非工作日的预测。实例表明,该模型实用有效、预测精度高。

The advantages of applying simulated annealing algorithm to short-term load forecast include less model complexity,high forecasting accuracy and global optimal property,which alleviate the tendency of traditional BP algorithm to be trapped in local minimum. The temperature and the day of week are considered in this model for the forecast of weekday and weekend loads. The practical tests show its high efficiency and accuracy.
