Switch Optimal Planning in Distribution Networks based on Dynamic Programming

In order to improve the flexibility and reliability index of distribution network, a certain number of segments and tie switches are needed. The main function is to minimize the outage area when the power outage, or load exchange between different roads. Without considering the reliability of the switch itself under the condition of the sectionalizing and tie switches allocation more reliability of power during operation is higher, but at the same time, the more the number of switch configurations, the power grid construction cost is higher. In the process of power grid construction, it is necessary to pay more economic cost in order to obtain higher reliability. This article embarks from the reality, in the study of dynamic programming method for distribution network based on switch configuration algorithm, combined with the characteristics of distribution network construction, contact switch configuration optimization section, distribution network is put forward, and the actual grid optimization experiment, verify the correctness of the method.
