Performance of Grid-Connected Shunt Active Filter Equipped PV System

The control and co-simulation of a gridGrid-integrated photovoltaicPhotovoltaic (PV) system with a shunt active filterActive filter are the major topics of this work. Under distorted gridGrid voltageVoltage settings, the proposed system's control performance and gridGrid interface behavior are examined, and harmonicsHarmonics and reactive currentsCurrent brought on by nonlinearNonlinear loadsLoad are made up for. In MATLABMATLAB/Simulink, the simplified circuit of a PV arrayPhotovoltaic Array with MPPT is modeled. The power systemPower systems blocks of MATLABMATLAB/Simulink are compatible with the created PV arrayPhotovoltaic Array model. In addition to injecting active powerActive power at the PCC, the voltage source inverterVoltage source inverter utilized in gridGrid-interactive PV systems also compensates for loadLoad-reactive powerReactive power and maintains a sinusoidal currentCurrent from/to the gridGrid. Under shifting solarSolar insolation and temperature circumstances, the injected active and reactive powersReactive power are controlled by altering the phasePhase and amplitudeAmplitude, respectively, of the inverterInverter output voltageOutput voltage. The signals for pulse width modulationPulse Width Modulation (PWM) employed to toggle the elements within the inverterInverter circuit are generated by hysteresis currentCurrent controllersController. To validate the efficiencyEfficiency and robustness of the suggested system, a simulation model was developed within the MATLABMATLAB/Simulink platform and co-simulated on the DSP TMS320F2812 processor.
