Integration of renewable energy sources in distribution networks is a necessity of the present era. Conventional power generation is fossil-fuel-dominated, but we must move on to renewable-based power generation due to the immediate consumption of fossil-fuel-based energy resources and increasing global warming in the current scenario. Solar, wind, fuel cells, small hydro plants, and other renewable-based power-generating technologies are popular, and they are often produced on a small scale of a few megawatts. They are commonly called distributed generators and are connected to distribution networks. Due to the intermittency of nature, i.e., solar irradiance, wind speed, and many other factors, these distributed generators are not feeding consistent power to the distribution network; because of this, the distribution network faces many challenges, such as variations in voltage profile, power quality issues, and highly active and reactive power loss. To overcome the above condition, the authors have proposed installing UPQC, the most effective D-FACTS device in renewable integrated distribution networks. Moreover, it has demonstrated the validity of the above objective on the IEEE 33 radial bus distribution network.
