Solar-wind hybrid energy system using MPPT

Development of energy-saving technology to maintain the functioning of a wind-solar electrical system

“…Authors of [6], in order to improve the MPPT function of hybrid controllers, suggested a specialized algorithm that was developed based on the simulation of subsystems of wind and solar power, rechargeable battery, and inverter, based on MATLAB Simulink. Paper [7] proposed using a constant voltage method to maximally transmit power based on the MPPT function of hybrid controllers. The conclusion was drawn about the necessity to define key features in the application of the method.…”

“…The conclusion was drawn about the necessity to define key features in the application of the method. However, by emphasizing the relevance of the combination of two different energy sources and the MPPT capability of hybrid controllers for finding maximum power, authors of [3][4][5]7] do not consider the need to maintain the capacity of a rechargeable battery in terms of adjusting the generation and consumption of energy in the structure of a wind-solar electric system. The constructed algorithms [2,6], aimed at improving the MPPT function of hybrid controllers, which confirmed the ability to obtain maximum power from each source of energy, do not take into consideration electricity consumption in terms of its adjustment to its generation.…”

“…Based on analysis of the scientific literature [2][3][4][5][6][7][8][9][10][11], it was found that the hybrid charge controller as part of a wind-solar electric system maintains the charge of a rechargeable battery by using a thermoelectric battery as a nonregulated ballast. Resetting the excess energy to the ballast when using the MPPT functions of controller leads to the uncompensated-for losses of electrical energy, which does not make it possible to ensure an appropriate level of the charge capacity of a rechargeable battery.…”

Maximum power extraction of hybrid photovoltaic ‐battery system with nonisolated single‐input and dual‐output DC‐DC converter: An efficient RFAMAO approach

“…The HRES is broadly studied in solar wind energy system, where to acquire maximal power with power extraction. The stable voltage mode is employed in HRES for obtaining a stable voltage in battery charge 37 . Nevertheless, the usage of this mode creates huge oscillations, also needs longer time of convergence 38 .…”

Modelling of a renewable energy‐based AC interconnected rural microgrid system for the provision of uninterrupted power supply

“…A solar-wind-based system needs to be backed by additional sources due to uncertainty depending on prevailing environmental conditions, with a day/night scenario [25,26]. Also, the rate of generation change in SPVS is very fast due to cloud transient [27].…”
