计算电力系统稳态潮流，使用直角坐标下的牛拉法，用牛顿迭代求解非线性方程组。计算结果包括节点电压、发电机注入功率、负荷注入功率支路始端功率、支路末端功率、支路损耗、网络损耗 (Calculation of the steady-state trend of power system, using ox-drawn in the rectangular coordinate method for solving nonlinear equations using Newton iteration. The calculation includes the node voltage of the generator into the power load to inject power slip began end power, slip the end of the power branch outages, network connectivity loss)

When doing optimization, GA algorithm was initially selected, but the instability of the GA (or local optimization) is really frustrating, before and after the resulting difference can at times reach more than 30 , at that time due to time reasons, I chose to optimize 1000 times, then the minimum value of the most optimal solution. Although the problems are solved, but an academic, this style of running is pretty embarrassing. So, I downloaded a GA-PSO algorithm, try using the combination of GA and PSO optimizing strategies, results algorithm issues, efficiency and good. I downloaded the original algorithm, there is a problem is that it is aimed at all upper and lower limits of the design variables are the same, so I modified the program and improvements, you can now deal with upper and lower limits of the inconsistency problem and fix the bug. Now, program modifications, and share, hoping to be useful to you
