BPA与用matlab编写的潮流程序matpower的接口程序，有详尽的说明，经过实例验证(Program of the BPA written using matlab trend program matpower the interface, detailed instructions after instance verify)

以IEEE33节点为例，考虑到配电网多为辐射性结构，选用前推回代法， 前推功率，回代电压，该算法通用性强(Taking the IEEE33 node as an example, considering that the distribution network is mostly radiative structure, the forward and backward substitution method is adopted, and the power is pushed forward and the voltage is replaced. This algorithm is universal.)

包含电气工程专业新能源发电课程中的光伏模型和风电并网模型，能在matlab中正常运行。(Including photovoltaic models and wind power grid-connected models in the new energy generation course in electrical engineering, which can operate normally in matlab.)

分别对速度、磁场两个分量进行独立控制。通过控制转子磁链，以转子磁通定向，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)
