PV-UPQC with MFA-SMC controller to Mitigate Power Quality Problems

The goal of this study is to provide a detailed description of the design of a Unified Power Quality Conditioner (UPQC) system, which is intended to enhance the power quality of three-phase power distribution grids. UPQC is a device that functions in a manner that is analogous to that of a Unified Power Flow Conditioner in that it makes use of two voltage source converters (VSCs) that are coupled to a capacitor that stores direct current energy and, in some cases, renewable energy sources like solar panels or wind energy. These two variable speed controllers are linked to the grid in the roles of shunt compensator (SC) and series compensator, respectively (SE). A UPFC is utilized in a power transmission system to carry out shunt correction and serial correction concurrently. Although a UPQC in the distribution network is responsible for shunt and serial compensation, these two compensation systems’ underlying operational concepts are distinct now. A UPFC should only offer operational concepts are distinct now. A UPFC should only offer line spends most of its time operating in an environment that is line spends most of its time operating in an environment that is distribution system will often occasionally function with imbalance, distortion, and even DC components when operating. To increase performance, which is necessary to evaluate the functionality using MATLAB/Simulink, the proposed UPQC takes into account all of these aspects while providing shunt or series compensation with the Sliding Mode Controller (SMC) and Moving Average Filter (MFA) method.
