| Abstract | Demand response (DR) has a key role in reducing the peak load and avoiding the construction of unnecessary power plants. In this study, the new modified framework is presented to plan and control DR programmes (DRPs) with a novel mathematical model. The proposed hierarchical DRP is designed at three time levels to flatten the load curve, to balance between supply and demand, and to support system frequency. The proposed structure consists of three control loops with different response times from a fraction of a second to several hours for scheduling DR via defined control parameters in this programme. To minimise load variations and customer cost, the novel objective function based on weight matrices is presented. To optimally transfer loads, these matrices are weighted based on power market prices, load level, and flexibility of loads. Moreover, the demand flexibility index is used to take into account the uncertainty in the predicted load pattern and reduce errors of aggregation demand. The proposed programme has been implemented on a 20-kV feeder to indicate its effective performance compared to hopping DR and centralised direct load control (DLC). The proposed mathematical model is verified by numerical results. |

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.
