Because future load demand is expected to rise, generation will need to rise as well. The usage of traditional resources such as coal, diesel fuels, and other fossil fuels contributes to global warming, prompting us to switch to renewable energy sources. Solar, wind, and tidal energy are examples of renewable energy resources that can be used to generate electricity. These are employed as Distribution Generators (DG) in small quantities throughout a bus system. We refer to these sources as micro-grids since their generation is reduced when they are connected to the grid. These DGs are often used to distribute electricity to loads in micro grids, and power electronic elements are used to manage the generation. It adds energy to the system, but it also causes harmonic distortions and voltage drops. We deploy a UPQC (Unified Power Quality Conditioner) technology to reduce sags and harmonics in the micro grid system generated by the power electronic devices used by renewable energy sources. The UPQC technology removes harmonics from the system and restores the micro-grid system's voltage. We use RES (Renewable Energy Resources) at the DC-link to create a new topology called instantaneous reactive power (irp) theory in the UPQC control to operate more efficiently. The RES support the UPQC system by injecting the active power generated by the resources through DC-link.
