Distributed Generation Planning Model and Algorithm Considering Static Voltage Stability Constrain in Distribution Network

研究了配网中分布式发电(distributed generation,DG)的规划问题,建立了一种考虑静态电压稳定约束的DG规划模型,提出了基于遗传算法的模型求解方法。将该方法应用于69节点系统进行测试,结果表明上述模型与算法是可行的。计及静态电压稳定约束导致该模型的计算量增加了,文章最后对提高该模型计算速度的方法进行了探讨。

The DG planning in disu＇ibution network is researched and build DG planning model, in which the security and economy are taken into account, is built; the constraint conditions of static voltage stability are considered. A genetic algorithm （GA） based flow chart to solve the planning scheme for DG is given. The built planning method is applied to a 69-bus power system to illustrate the feasibility of the built method. Due to considering the constraints of static voltage stability, the calculation amount of the built planning model is increased, so the method to speed up the calculation is discussed.
