“…This proposed method used control strategy techniques is employed to retrive the fundamental harmonic component [13]. The preferred technique must be suitable for mainly two states such as stable (or steady state) and transient state condition [14][15][16][17][18]. In this section, steady state analysis and transient analysis is done with the help of Fast Fourier Transform (FFT) for the following control techniques.…”

The SPV interfaced grid system with battery storage unit, bidirectional VSI interconnected shunt active filter, an adaptive Proportional Integral (PI) controller is employed for improve current and voltage profile enhancement. The p-q theory is the common employed technique to extract the basic fundamental current harmonic components from affected or polluted power supply by means of diode rectifier or non linear load. The basic concepts of reactive power (IRP) theory includes it’s a time domain model and it can be applicable for both 3P3W and 3P4W. Initially, the control technique called instantaneous real and reactive power theory or p-q theory has been developed for three phase three wire system and then later it was extend to three phase four wire system. This system is valid under steady state as well as dynamic state. The bidirectional VSI based shunt APF is controlled by the PI based instantaneous reactive power theory. The proposed PI Controller interfaced shunt Active Power Filter is used to maintain DC-Link voltage.SPV system is interfaced with incremental conductance MPPT algorithm. This SAPF control scheme has to provide the following benefits like current harmonic mitigation as well as reactive power compensation

The aim of this paper is to investigate the effect of increased penetration level of Photovoltaic (PV) generation on the distribution network. Harmonic distortion is the main factor studied in this paper and a typical three-bus distribution network is built in MATLAB/Simulink to understand the harmonics problem. The obtained results show that current harmonics are more susceptible to fluctuate compared to voltage harmonics. Based on existing IEEE harmonic standards, total demand distortion of current (TDDi) is evaluated to estimate maximum PV penetration level at Point of Common Coupling (PCC), and the maximum acceptable TDDi at each bus differs according to specific loading and short-circuit levels. Meanwhile, total harmonic distortion of current (THDi) at inverter outputs represents inverter performance. Instead of assessing at standard test conditions (STC), the impact of irradiance variations is studied. Low irradiance results in an increased THDi of the inverter whilst doesn't explicitly affect TDDi at PCC. A simple and low-cost solution is proposed to dynamically vary the settings of inverter's filter elements against irradiance, and harmonic distortion at low irradiance of the inverter is successfully mitigated.

“…However, the use of passive filter or separate active filter in grid-connected system raises its size, weight, and cost, which are the main shortfalls among others of this solution. To surmount these defects, PV system itself acting as a shunt active power filter has been proposed by multitude researches as indicated in the literature [4][5][6][7]. Indeed, by injecting the appropriate compensating current into the grid, the filtering function of the PV system can improve the current harmonic distortion, power conversion efficiency, and reliability [8][9].…”

This paper proposes a combined nonlinear backstepping approach with direct power control technique for improving power quality of a three-phase grid-connected solar energy conversion system. The presented system basically extracts maximum power from solar photovoltaic array, converts it into AC power via a voltage source converter, and supplies it to the grid and connected loads. The proposed system offers not only the function of grid connected PV system but also it acts as a shunt active power filter (PV-SAPF). The system intends to eliminate the poor power quality issues and provides current conditioning while operating in coherence under nonlinear load variations. In order to validate the proposed double function system, processor-in-the-loop (PIL) tests are carried out for steady state and dynamic regimes under a nonlinear load operating condition.
