Abstract | In this paper, support vector machine (SVM) technique is applied to predict the reliability of power distribution system. To determine the SVM models' optimal parameters for regression, particle swarm optimization algorithm is improved by combination with chaotic searching method (CPSO). The implementation approach of SVM for regression with CPSO (CPSO-SVR) is detailedly given. The CPSO-SVR models are first trained to learn the relationship between the influential factors of historical reliability and the corresponding reliability targets, and then future reliability can be predicted. In addition, a single but comprehensive index for distribution reliability is defined as IPSR. To examine the effectiveness of the proposed method, numerical experiments for the reliability forecasting of a city's power distribution system in Southern China are conducted. The results reveal that CPSO-SVR outperforms the existing with higher forecasting accuracy and more robust performance. Hence, the proposed CPSO-SVR method is a proper alternative for forecasting power distribution system reliability. Furthermore, sensitivity analyses of input influential factors are demonstrated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
