Generally , forecast techniques introduced here are simple , but they can be as valuable and reliable as complicated ones such as input - output and economic models for many small regions or cities
本文介绍的比例参数和线性外推方法简单、成本低，对数据要求不高，因此对中小城市或地区，特别是发展稳定的地区，是一个相对比较可行并且可靠的方法。
After a short - term load forecasting method based analogous and linear extrapolation is proposed , the load forecast and the priority of equipment action are led into static reactive power optimization . the aim function is constructed for the practical situation of power system . on the basis of traditional genetic algorithm the fitness function and the holding of population diversity are improved
在提出基于相似日和线性外推的短期负荷预测新方法的基础上，将负荷预测和设备动作优先级引入静态无功优化中，并结合电网实际情况，构造了实用的目标函数，对遗传算法的适应度函数和群体多样性的保持进行了改进，采用邻域搜索算子增加遗传算法的局部寻优能力。
