An improved hybrid PV‐wind power system with MPPT for water pumping applications

Abstract

SUMMARY This work articulates the hybrid photovoltaic‐wind power system development for water pump applications. The proposed control scheme is based on modified Artificial Bee Colony (ABC)‐based on Maximum Power Point Tracking (MPPT) algorithm.. On power circuit part, the single CUK converter‐fed induction motor driven a centrifugal pump and has been employed, which improves the system overall performance. The proposed MPPT control provides the smooth propagation of the motor operation as well as forces the photovoltaic system to operate always in maximum power point (MPP) region. Further, the modified ABC algorithm strengthens searching competency and has been employed for the achievement of local optimal maximum power point (MPP) under partial shade conditions with high accuracy and zero oscillation around MPP region when compared with other optimized algorithms. Particle swarm optimization‐space vector pulse‐width modulation (PSO‐SVPWM) was adapted for the inverter; control with standard v/f control is implemented in this work for better speed regulation and reduction in total harmonic distortion. Moreover, the power balance of the integrated hybrid system to the DC bus has been discussed with practicality. This article also explains the comparison of different MPPT algorithms and includes PSO, ant colony optimization, firefly algorithm, and ABC under fast‐changing environmental conditions. In the case of classical ABC method, only one scout bee is responsible to achieve the local maximum. The proposed modified ABC has been used to improve searching capacity, with the addition of scout bees. Experimental results are presented and reveal that the modified ABC algorithm performs 7.5 times faster than the standard PSO technique. Prototype model in hardware setup is developed with MATLAB/Simulink interfaced with dSPACE DS 1104.

An effective standalone hybrid wind‐ photovoltaic water pumping system with reduced power converter count

“…20,21 In a WPS using an AC motor pump, the MPPT from solar PV and WECS is typically ensured by employing a dedicated power converter for power conditioning from either source and an additional converter to integrate power from these sources. 22,23 Such systems require more power devices resulting in increased losses and system cost. To overcome these drawbacks, few studies have proposed power processing of AC motor-based WPS using reduced converter count.…”

Internet of things augmented a novel PSO‐employed modified zeta converter‐based photovoltaic maximum power tracking system: hardware realisation

“…However, climate dependency and high implementation cost are the major challenges of the present PV power system. The maximum power point tracking (MPPT) is essential for the achievement of maximum power point (MPP) because of non‐linear voltage/current characteristics as well as fast divergence of solar insolation level [3, 4]. For the efficient running of any PV‐based driven system, MPPT is an essential component.…”

A Review of Modification Methods of Solid Electrolytes for All‐Solid‐State Sodium‐Ion Batteries

“…The instability of power generation level affected by climate leads to the difficulty of grid connection. [20][21][22] The equipment loss caused by the current from big to small will reduce product life. Nevertheless, in terms of the energy storage systems, the peak power supply of the grid can be adjusted.…”
