Abstract
This paper presents the low-cost hardware implementation of solar inverter-based STATCOM for correction of power factor in case of non-linear industrial load. It explores the multifunctionality of PV inverters to not only deliver real power but to deal with other power quality issues like poor power factor due to non-linear load. This multifunctionality is achieved in the daytime with the capacity of the inverter remaining after supplying PV power to the load/grid. At night time, the full capacity of the inverter is available for grid support functionalities. In the developed prototype, the decoupled control techniques were implemented using the STM32 microcontroller. A modified SOGI based estimator is used to find grid voltage angle as well as the reactive component of the load current. Experiments are done for various conditions of load and variable solar insolation, and results are discussed to validate the proposed system.
