摘要： Single phase tied with Photovoltaic arrangement (PV) employed on perturbed & observed (P&O) maximum energy point tracking technique with shunt active power filter allied to a rectifier feed R-L nonlinear load. The traditional Perturbed & Observed technique maximum energy point tracking topology is applied to attained maximum output power from Photovoltaic array(PVA), Proportional Integral conventional controller with phase detector (PLL) (PD) phase synchronization are executed to produce reference current. It provide at control unit of pulse width modulation topology( PWM) is utilized in inverter to get steady output voltage. Self supported DC bus PWM converter is regulated from PV array. In proposed architecture is minimized total harmonic pollution existing in supply current owing to power electronic load is (PEL). Total current harmonic pollution (THDi) factor obtain better than compensated using dynamic filter shunt active power filter (SAPF) and power compensation. Hence, reactive power (KVAR) is delivered through system decrease and active power (KW) enhance. The suggested scheme has been implemented by way of MATLAB/SIMULINK 2015(a) environment.

Modern control scheme for Z-Source inverter based PV power generation systems
摘要： Z-source inverter (ZSI) based photovoltaic power conversion system (PV-PCS) provides both the DC link voltage boost and DC-AC inversion in single stage with added features. Traditional maximum power point tracking (MPPT) control algorithm generates the required shoot-through interval to output maximum power to the Z-network. At this instant, the voltage across Z-source capacitor is equal to the MPP voltage of PV array. The capacitor voltage cannot be further increased if it is demanded by the load. This paper presents an improved MPPT control algorithm along with modified MPPT algorithm to achieve both the MPPT as well as capacitor voltage control at the same time. Development and implementation of the proposed algorithm has been carried out by Matlab/Simulink software and the results are provided.

摘要： Single phase system has been secured with Photovoltaic system based on Fuzzy Logic Control based perturbed & observed (P&O) maximum power point tracking phenomenon with active power filter (APF) connected to a nonlinear load. The conventional Perturbed & Observed algorithm is used to achieve maximum power output from Photovoltaic array, Proportional Integral controller with positive sequence detector phase locked loop(PLL) synchronization are implemented to generate reference current. It is emplyed to generate switching signal for VSI in hysteresis band current controlled (HBCC). DC link of PWM converter is controlled with switch controlled of VSI inverter. In proposed work minimize harmonic distortion present in source current due to power electronic based nonlinear load. Total current harmonic distortion (THD) is reduced by shunt active power factor and power factor improve after compensation reactive power supplied by system reduce and active power of system increase. The system designed with MATLAB/SIMULINK 2015(a) platform.
