PV Power Injection and DSTATCOM-Based Power Quality Enhancement

Abstract

The paper suggests a method for optimizing the Distribution Static Compensator's (DSTATCOM) DC-link voltage that is primarily based on the need for load compensation and makes use of a Reduced Switch Count Multi Level Converter (RSE-MLC) that is integrated with a Photovoltaic (PV) device. The suggested method can improve strength by correcting reactive strength, unbalance, and harmonics required with the use of three-segment unbalanced and non-linear loads related to the distribution aspect. It can also provide the weight with genuine strength support, keeping the source from overloading whenever needed. It is possible to lower the DC link voltage to a lower level during off-peak loads to minimize switching losses and lessen voltage strain across the inverter switches.

The variation of the DC-hyperlink voltage is given by using RSE-MLC, which needs a DC voltage source. This method uses renewable energy resources, such as solar cells, as the DC voltage source. With the employment of a High-Grade Boost Converter (HGBC), the PV panel's output voltage is increased to a higher level and sent to the RSE-MLC. The perturb look at (p & o) technique is used to monitor the PV panel's Maximum Power Point Tracker (MPPT). Through experiments and simulations, the effects have been verified.
