| Abstract | Solving the deterministic unit commitment (UC) model may yield the optimal commitment for each unit for a certain condition of the power system. Changing the system condition due to a sudden change or uncertainties may render the obtained solution infeasible or inapplicable to the system under study. This paper presents a fuzzy model to handle uncertainties associated with the UC problem and introduces a methodology based on the Ant Colony Search Algorithm (ACSA) to find a near-optimal solution to the problem. The ACSA is a meta-heuristic technique for solving hard combinatorial optimization problems, a class of problems which the UC problem belongs to. The ACSA was inspired by the behavior of real ants that are capable of finding the shortest path from food sources to the nest without using visual cues. The proposed approach uses a fuzzy comparison technique and generates a fuzzy range of the cost that reflects problem uncertainties. Test results on a 10-unit system demonstrate the viability of the proposed technique to solve the UC problem considering uncertainties. |

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.
