直接使用闭环结构约束,采用遗传算法对仅有2个变电站的环型配网进行优化规划.在配网优化规划的同时考虑到了结构上的环状约束和运行上的辐射状约束.首先介绍了环型配电网优化规划中采用的数学模型,然后介绍了遗传算法理论及其在环型配电网中的应用,并使用Visual C 编程语言,设计、开发环型配网优化规划软件.最后通过对一个17节点的试验系统的优化规划,验证了方法的实用性和有效性.

The distribution system planning is performed with a loop configuration constraint from scratch.With Evolutionary Algorithm,a sample distribution network is designed with a loop configuration,in which the system is operated as radial configuration.It firstly introduces the mathematical model for distribution network planning,then the application of Evolutionary Algorithm for the planning of distribution network.By using the theory mentioned above, Visual C++ is applied to develop the distribution network optimization software.Finally with the optimization process of 17 nodes system being showed,the presented algorithm's utility and validity is verified.
