Abstract

Grid-connected distributed energy resources (DERs) along with conventional power plants are the best solution to meet the increasing energy demand. But higher penetration level of these DERs may affect the system stability and its performance. DERs do not contribute any inertia unlike synchronous generators (SG) use conventionally. Absence of inertia results in large frequency variation, leading system to instability. To stabilize the system, virtual inertia can be added using short-term energy storage. This concept of virtual inertia is termed as virtual synchronous generator (VSG). This may be the basis for future grids with 100% renewable in India. The use of VSGs into the DERs interface to grid and off-grid is having several challenges. Electrical industry reliably integrates large amount of DGs/RESs into system; hence, it is important to pay attention for managing number of VSGs in the grid. The main aspect is to handle the changes in the system due to VSGs and to make the system robust, flexible and reliable. This article reviews the basic challenges in the implementation of VSG.
