Decoupled Adaptive Noise Detection control based Four-Leg Grid tied PV Inverter (VSC) Using FOPID Controller
Authors(1) :-Lokesh Panabaka A grid supportive two stage three phase four wire 4-Leg SPV (Solar Photovoltaic) system with Fractional Order PID controller is presented in this paper, wherein a boost converter is used as a first stage to serve the function of MPPT (Maximum Power Point Tracking) and a 4-leg VSC (Voltage Source Converter) is used to feed the extracted SPV energy along with supporting distribution system for improvement in the power quality. The elimination of harmonics, balancing of grid currents and compensation for non-active part of the load currents are additional features offered by proposed system other than conventional features of the solar inverter. The true power reflecting part of load current is estimated using FOPID Based decoupled adaptive noise detection (DAND) algorithm approach. The output of which is current component reflected on grid side to instantaneously regulate the DC link voltage using proposed Fractional Order PID. In the proposed approach, the load, PV array and loss contributions are kept decoupled. The feasibility of proposed control algorithm is confirmed via MATLAB/SIMULINK results.
