MATLAB编写利用P-Q分解法的潮流计算程序，程序中利用基于稀疏技术的因子表法进行迭代求解，以降低存储量，提高运算速度。本程序只适用于简单系统，如IEEE5节点系统。对于复杂系统，由于PV节点电压越限等问题尚未考虑，得到的潮流结果可能有误！(MATLAB flow calculation program written using PQ decomposition method, program utilization based on sparse iterative solver technology factor table method to reduce the storage capacity, improve processing speed. This procedure applies only to simple systems, such as IEEE5 node system. For complex systems, PV node voltage due to the more limited issues not yet considered, the trend of the results obtained might be wrong!)
