Mitigation of PQP in Distributed Generation using CPD’s

India is having the third-largest electricity consumers in the world and is also the largest renewable energy producer, accounting for 38 percent of global renewable energy production. Solar, wind, biomass, hydro, and fuel cells are examples of renewable energy sources. This paper begins with a description of the difficulties like voltage sag, swell, noise, interruptions, transients, and so on, before moving on to basic standards. Adaptive Linear Combiner (ADALINE) is a method for detecting and adjusting harmonics problems. ADALINE may also monitor voltage sags, swells, transients, and interruptions, among other things. Then, for micro-grid systems, we look at how to mitigate these issues by utilizing bespoke power devices like DVR, DSTATCOM, UPQC, and so on. Due to its numerous advantages, UPQC may be a viable option for renewable energy systems. The use of UPQC to analyze and resolve power quality concerns in distribution generating systems was confirmed through simulation using Matlab/Simulation.
