Analysis of Power Quality Issues and Implementation of UPQC Topologies to Enhance Power System Stability

Due to the depletion of fossil fuels, coal, and oil, traditional electricity generation has a difficult task for utilities. A cheaper and more efficient method of doing this is required. A different source is required to fulfill the consumers power requirements. The alternate source should be sustainable and capable of meeting the consumers requirements. The integration of renewable energy into the grid is a useful way to fulfill demand. Renewable energy integration confronts three major problems frequency variation, power quality concerns, and power system instability. The following problems were of critical importance. An analytic hierarchy approach based expert system is utilized to identify and categorize power quality incidents. Before, it could sense things like sag, swell, transients, harmonics, interrupts, and flickers. An error free event classification system has been suggested. Simplified procedure allows for improved detection and categorization of power quality incidents. an investigation of power quality incidents and their mitigation using unified power quality conditioners UPQC An Adaptive Neuro Fuzzy Inference System ANFIS is used to minimize various power quality issues. Integrating renewable energy sources efficiently minimizes the environmental impact. The suggested method provides a solution to voltage unbalances and lowers overall harmonic distortion at the point of common coupling PCC . The addition of an ANFIS controlled DVR is used to reduce voltage irregularities caused by integrating renewable energy sources and faults in the transmission line. An artificial fault was added to power quality events with the goal of making use of renewable energy. To minimize the adverse effects of power quality incidents, the ANFIS controlled DVR proposal is in place. ANFIS controlled DVR is contrasted to a traditional technique of surveillance. Distributed static compensator D STATCOM is used to prevent voltage flickers, and total harmonic distortion, caused by nonlinear loads. D STATCOM is suggested to use three control methods Instantaneous power theory, Synchronous vector PI Control, and Harmonic elimination. Under extreme load circumstances, the D efficacy STATCOMs is evaluated. The suggested expert system and the bespoke power devices will be analyzed and discussed using various control techniques.
