A DVR-Based Compensation System Under Various Power System Faults in a Multi-microgrid

In today’s contemporary world, electricity is an essential resource. Access to electricity accelerates a country's growth. The majority of power is generated from fossil fuels, which have a negative impact on the environment. This encouraged people to produce power using renewable energy sources such as solar and wind. This expanded the volume of microgrids available at the consumers’ end. The power system is a massive and complicated network that includes the generating, transmission, and distribution systems. Numerous power quality issues such as voltage sag, voltage swell, harmonics, reactive power compensation, and voltage distortions, arise as a result of building microgrids at the consumer ends and connecting various types of loads. Among these, the work aims to reduce voltage sag, voltage swell, and harmonics induced by the rise in load and non-linear loading at the consumer ends. Flexible AC Transmission Systems (FACTS) devices are used to address these power quality challenges. A Dynamic Voltage Restorer (DVR) has been considered as a solution to this problem. A multi-microgrid is modelled in MATLAB and simulated with varied load situations that cause power quality concerns in multi-microgrids, and the findings are provided in this paper.
