Description
Summary:To meet the constantly rising energy demand, renewable energy sources are increasingly being used in power networks, transforming the traditional power distribution system into a microgrid (MG) based system. Simultaneously, the presence of nonlinear loads in the MG system may cause unwanted power quality (PQ) issues, which must be thoroughly addressed. The use of a shunt active power filter (SAPF) to mitigate PQ problems in a standalone MG system is discussed in this paper. SAPF performance must meet a number of requirements, including constant dc-link capacitor voltage, continuous input current flow, and lower switching loss, all of which are difficult to achieve with a traditional voltage source inverter (VSI). A new inverter named split source inverter (SSI) has been recently developed and has all the above features. In SSI, both the dc and ac sides are regulated using modulation index with the same control mechanism as that of normal VSI. The application of SSI with SAPF is yet to be explored in detail. As a result, a performance comparison of two inverters (traditional VSI and SSI) based SAPF with modified synchronous reference frame technique for generation of reference current, adaptive hysteresis current controller for generation of switching pulse, and proportional-integral controller or fuzzy logic controller for dc-link voltage regulation has been investigated in this paper. Under ideal/non-ideal source conditions, the proposed SAPF outperforms other counterparts in terms of dc-link voltage regulation and mitigation of harmonics generated by various nonlinear loads.
