| Abstract | The energy storage system is the backbone of an isolated microgrid (MG), which helps to provide a secure and reliable power supply. The operation of the MG systems operating without storage is affected highly due to intermittent generation and sudden load demand fluctuations. This study investigates the operational behaviour of an isolated MG system in terms of frequency and power balance by incorporating the Micro Pump Hydro Energy Storage (MPHES) system. The investigated MG system consists of biodiesel, solar and wind-based generating units with MPHES and battery as energy storage systems. The realistic data for solar and wind resources have been used to consider the practical scenario of any area. The recently developed coyote-optimisation algorithm is employed for optimal tuning of the proportional–integral controller using the integral of time multiplied absolute error criterion. The simulation studies have been conducted to investigate the performance of the MG system by incorporating the MPHES system for a typical day (36 h) under various operating conditions. The analysis reveals that the MG system exhibits smoother and consistent dynamic performance by including the MPHES unit and efficiently utilises renewable power. |

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.
