内点法计算14节点系统最优潮流，目标函数为燃料费用最小(Optimal power flow of a 14-node system by using interior point method)

该程序计算翅片式冷凝器选型软件，制冷剂为R22,根据冷媒侧进出口参数求换热面积。比较实用的(The program calculates fin type condenser selection software, refrigerant R22, according to refrigerant side inlet and outlet parameters for heat exchange area. More practical)

说明：  区域综合能源系统中热-电联合建模，通过使用扩展牛顿拉夫逊算法进行统一求解，同时得出系统内热力系统和电力系统的状态参数。(The joint thermal-electrical modeling of regional integrated energy system is solved by using the extended Newton-Raphson algorithm, and the state parameters of the thermal system and the power system in the system are obtained.)

可以进行辐射状8节点配电网的状态估计，但是由于权重的选取不合适，程序收敛，但估计质量不高，可以通过合理的选择权重，来达到很高的估计质量。(Radial 8 nodes distribution network state estimation, but inappropriate due to the weight of the selected program convergence, it is estimated that the quality is not high, can be a reasonable option weight to achieve a high estimation quality.)
