In this paper, fuzzy logic controller (FLC)-based three-phase shunt active power filter with photovoltaic (PV) system is proposed. This filter comprises voltage source converter (VSC) with DC link capacitor at the input side and is supplied by PV system. The salient feature of the filter is that it provides reactive power compensation with line current harmonic reduction and also neutral compensation at point of common coupling (PCC). The PV system and a battery are connected with VSC through DC–DC converter. This paper also proposes a control algorithm using instantaneous [Formula: see text]-[Formula: see text] theory that generates a reference current to counteract the harmonics. The FLC controls the DC link voltage in reference to the above reference current. The performance of the proposed filter for compensation is confirmed by using the MATLAB/Simulink environment and results are validated.

Abstract This paper presents a single stage solar PV (photovoltaic) grid integrated power generating system using a three level voltage source converter (VSC) operating at low switching frequency of 900 Hz with robust synchronizing phase locked loop (RS-PLL) based control algorithm. To track the maximum power from solar PV array, an incremental conductance algorithm is used and this maximum power is fed to the grid via three-level VSC. The use of single stage system with three level VSC offers the advantage of low switching losses and the operation at high voltages and high power which results in enhancement of power quality in the proposed system. Simulated results validate the design and control algorithm under steady state and dynamic conditions.

In this paper, grid-connected photovoltaic-wind energy, including a battery energy storage system (BESS) with a novel topology base proposed controller, is presented. The battery can be reflected in a smooth and stable output under variation of weather and load conditions for the grid-connected system. Robust phase-locked loop- (PLL) based hybrid Voltage Source Converter (VSC) controller is designed to enhance power quality (PQ) with mitigating power fluctuation at DC-link by applied BESS on the DC side. The results can be summarized in 2 stages; in the 1st stage, the performance of the designed hybrid system can be analyzed with untuned parameters of the converter, and in the 2nd stage, a simple strategy base proposed controller to improve the operation stability and analyze the PQ of the hybrid power generating (HPG) system is developed. Finally, the proposed hybrid system is modeled in MATLAB/Simulink and the simulation results as obtained are compared with an existing controller. HIGHLIGHTS Performance analysis of design a grid connected hybrid power generating system The system achieved stability and reliability with proposed controllers The presence of a battery, providing smooth movement of the generated power of the system A coordinated controller designed to improve power fluctuation and power quality Highly robust grid-connected HPG system designed using hybrid VSC and bidirectional controller GRAPHICAL ABSTRACT
