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

Objective: This study presents the unified power quality conditioner (UPQC) which is based on eight switch converter for dropping the total harmonic distortion. Alleviation of power quality is accomplished by power fed to the DC link of the converter and regulates the power using intelligent controller. Methods: The function of UPQC is determined by how fast and precisely compensation signals are estimated. The UPQC has presented for reducing the coupling problem by the presence of switching leg. In the distributed system needs to explain the approaches for standard supply voltage droop and voltage swell. Findings: The harmonics is reduced and produces the dynamic response in eight switch converter using genetic algorithm (GA). Application/ improvements: In the distribution system eight switch converter based UPQC has generated the steady state and dynamic process of control in nonlinear load and/or utility voltage conditions is implemented in MATLAB Simulink.

In this paper, gravitational search algorithm (GSA) is used for improving the control strategy of unified power quality conditioner (UPQC). The UPQC is considered with wind energy conversion system (WECS) and grid/load to determine the dynamic behaviors. The proposed control technique alleviates the power quality (PQ) problems in the WECS. Here, the GSA approach is used to identify the ideal solutions from the available search space and the method enables the UPQC to perform under different test conditions. Initially multiple parameters are considered such as, voltage, real and reactive power and current. Amid the load variations, the proposed method will regulate the power loss, and voltage instability problem. The proposed system is tested for different PQ issues. In order to evaluate the effectiveness of the proposed method, three different cases are considered they are performance of GSA under balanced condition, under unbalanced condition, under motor speed condition. The performance of the proposed GSA based UPQC system is validated through simulations using MATLAB/Simulink and compared with existing techniques such as FA, base model and ANFIS techniques. From the comparison analysis, we can infer that the proposed control technique is very much effective in enhancing the power quality of the system than the existing techniques.
