A New Two-Leg Converter-Based Multifunctional TPFW Grid-Tied Single-Stage Solar PV System

This paper proposes a multifunctional grid-tied solar photovoltaic (PV) system with a multifeatured adaptive control using a two-leg voltage source converter (VSC). This topology provides multifunctions such as injection of real power output from a PV array and improvements of power quality. It provides reactive power compensation; hence, unity power factor (UPF) is realized at the grid. Moreover, it performs various functions such as balancing of grid currents, harmonics mitigation and compensation of neutral current. The maximum power point tracking (MPPT) algorithm is used for harvesting the peak PV array power. The proposed topology is simulated using MATLAB/SIMULINK toolbox. Simulated responses are validated through experimental results. © 2021, The Institution of Engineers (India).
