| Abstract | This paper proposes a different way to model the violation penalties in the price-based economic dispatch algorithm used at SPP. Instead of using a flat violation penalty rate to discourage operating constraints violations, a MW dependent multi-step violation penalty function is introduced. A comparative study is preformed to analyze the impact of the new violation model on the average prices and price volatility on the one hand, and on the number and magnitude of the operating constraint violations on the other hand. A multi-step penalty function provides more flexibility for the market analyst to find the right penalty structure that reconciles the two conflicting objectives: minimizing price excursions and minimizing operating constraint violations. A comparative study is performed where test cases are subjected to three types of violation penalty profiles: one single rate profile and two multi segment violation penalty profiles, each with different segment sizes. The purpose of the different segment sizes is to provide some idea of the sensitivity of the study results with respect to the sizes of the segments. |

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.
