| Abstract | Under the background of large-scale development and utilization of clean energy, there are serious security and stability risks and load balance problems in power grids with high penetration of clean energy and high portion of external power supply. Therefore, Jiangsu Electric Power Company has started the construction of the millisecond accurate load control system (MALCS). In this article, the theoretical basis of the MALCS is introduced from several aspects: the interruptible load, steady state, and transient state control technique of large-scale load. On this basis, the authors put forward the overall architecture, transmission channel structure, and control strategy of the MALCS. Subsequently, this article introduces the first-phase and the second-phase projects of MALCS construction in Jiangsu power grid, and the actual load-shedding test of Jiangsu MALCS. The results of the actual test show that the overall motion time of the Jiangsu MALCS meets the design requirements, and the MALCS can offer an effective frequency support to Jiangsu and East China Power Grid in case of severe failures. Finally, this article summarises the experience of MALCS construction, introduces the expansion plan of MALCS, and forecasts the future development direction and application of the system. |

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.
