| Abstract | The substation expansion planning (SEP) is a complicated problem with a wide variety of its constraints. This paper presents a novel and efficient method to solve optimal SEP problem to determine optimal number, location, capacity, timing, and associated service area of each substation under all technical constraints over the planning period at minimum costs. In this respect, the genetic algorithm (GA) based k-means algorithm is developed to overcome some disadvantage of k-means algorithm to find optimal locations of new substations without any predetermined candidate locations. In this case, the GA is adapted based on k-means to place the substations in the centroid of their loads while location of existing ones is fixed. Moreover, allowable loading of substation is considered by a determined penalty cost in object function of GA to prevent placing substations where they may be overloaded. Then, the greedy heuristic algorithm is used to solve dynamic programming for optimal load assignment based on priority of load connection. The technical constraints such as permissible voltage drop and maximum loading substations, thermal limit of MV feeder, radial network is considered at this stage. The proposed method is used to solve optimal pseudo-dynamic SEP problem for Tabriz, which is the capital city of East Azerbijan province of Iran to verify efficiency and capability. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
