建立永磁同步电机预测模型,实现了永磁同步电机id=0矢量控制.(Vector control of permanent magnet synchronous motor)

功能是在有潮流约束，碳排放约束，电压和无功约束等条件下的发电权交易模型，采用基于约束松弛变量策略的中心校正内点法求解(There is a trend in the function generation right transaction model under conditions of constraint, carbon constraints, voltage and reactive power constraints, using slack variables to solve the constraint-based policy center corrector Interior Point Method)

灰色预测方法的特点表现在：首先是它把离散数据视为连续变量在其变化过程中所取的离散值，从而可利用微分方程式处理数据；而不直接使用原始数据而是由它产生累加生成数，对生成数列使用微分方程模型。这样，可以抵消大部分随机误差，显示出规律性。(The characteristics of the grey prediction method are as follows: First, it regards the discrete data as the discrete value of the continuous variable in its change process, so that the differential equation can be used to process the data; instead of using the original data directly, it generates the cumulative generation. Number, using a differential equation model for generating a series. In this way, most of the random errors can be offset, showing regularity.)
