| Abstract | This study presents a new method for voltage unbalance compensation in islanded microgrids using distributed resources (i.e. distributed generations, storage systems) and responsive loads. The proposed method adopts the Newton trust-region approach to perform the load flow calculation. The sensitivity coefficients obtained from the load flow solution are incorporated into an optimisation problem whose cost function is defined based on voltage unbalance factor at all microgrid buses. The problem is solved using the particle swarm optimisation method. The results of the optimisation method in the form of correction commands are transmitted to the responsive loads and resources via a communication structure. The responsive resources even those with limited capacity and various types of loads including residential, commercial, and industrial are considered in the presented studies. In order to evaluate the performance of the proposed strategy, two different cases, namely, with and without energy storage devices, are simulated. Simulation results confirm the effectiveness of the proposed method in the voltage unbalance correction of islanded microgrids. |

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.
