A hybrid filter as an integral component of HSES for establishing smart cities

Rising penetration of renewable energy based distributed generation system in the utility grid has raised serious concerns towards poor power quality problem. The problem gets further alleviated if the electric system is intended to operate under smart gird philosophy. Management of bidirectional power flow with the utility and smart loads is a tricky aspect. The paper presents an innovative solution to overcome the power quality problem in a smart grid environment where major generation of power is catered through hybrid sustainable energy system (HSES). Methodologies for integrating a hybrid active filter (HAF) and its control aspect is demonstrated. Case study highlighting the role of HAF in a hybridized renewable energy regime demonstrates the effectiveness of proposed solution.
