Abstract | A demand response aggregator (DRA)-coordinated load scheduling in distribution system with responsive loads is presented. The mutually exclusive scheduling objectives of demand response provider (DRP) and distribution network operator (DNO) are optimally compromised by DRA through incentive-based participation strategies of DRPs. Thus, the proposed methodology is a two-stage optimisation process in which the prioritised schedules (to minimise total electricity charges/cost) of DRP obtained through first-stage optimisation are rescheduled by DRA in the second-stage optimisation considering the system/DNO benefits. The proposed methodology considers the behaviour (risk averse nature, incentive favourable nature etc.) through DRPs registration in various participation strategies. The effectiveness of proposed methodology on techno-economic aspects/attributes is examined using IEEE 34 bus distribution system for different operating conditions. The sensitivity analysis include the effect of load schedules due to change in strategy election by DRPs, change in performance attributes with respect to the penetration levels of responsive loads. The simulation results demonstrate the effectiveness of DRA-coordinated load scheduling over base case with no responsive loads as well as prioritised schedules of responsive loads by DRPs. The optimal compromise between the objectives of DRPs and DNO is observed in terms of system wide benefits and electricity charges/cost of DRPs. The variation of techno-economic aspects differs between DRPs-based schedules and DRA schedules at higher penetration levels. |

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.
