【摘要】：三相有源配电网无功优化本质上属于非线性非凸规划问题,目前尚缺乏严格的有效求解方法。针对配电网辐射状运行特点,文中建立了基于支路潮流形式的配电网的三相无功优化模型,然后采用二阶锥松弛技术将原始优化模型转化为具有凸可行域的数学规划形式。考虑电容器等离散的补偿设备后,模型进一步扩展为含离散变量的混合整数二阶锥规划模型。该模型可被现有优化算法包高效求解。采用IEEE 33节点和IEEE 123节点系统进行算例分析,验证了所提出的方法的寻优稳定性和计算高效性。
[Abstract]:The active reactive power optimization of distribution network is essentially nonlinear and non convex problem, there is still lack of effective methods for solving the strict. According to the operation characteristics of radial distribution network, this paper established the model of reactive power optimization based on three-phase power flow form, and then the two order cone relaxation technique the original optimization model is transformed into the mathematical programming form with convex feasible domain. Considering the discrete capacitor compensation device, the model is further extended to the mixed integer two order cone programming model with discrete variables. The model can be existing optimization solvers. Analyze this case by IEEE 33 bus and IEEE 123 bus system, verified the method the optimization of stability and computational efficiency.
