This study elucidates the use of optimization algorithms to identify the controller parameters employed in adjusting the current and voltage values of loads powered by solar energy systems and battery groups. Parameters for these controllers were independently derived using a combination of ant colony optimization with Levy flight, hybrid firefly‐particle swarm optimization, hybrid gravitation search algorithm‐particle swarm optimization, alongside the implementation of Jaya and whale optimization algorithms. The results from each method were juxtaposed for thorough analysis. In addition, three distinct Maximum Power Point Tracker (MPPT) algorithms were employed in the system: perturbation and observation, open circuit voltage, and incremental conductance (IC). To assess the system’s adaptability to real‐world conditions, it was tested against varying temperatures and sunlight levels. Moreover, potential changes in the loads were considered by varying the load. The efficacy of the controllers was examined by altering both the environment and load. The effectiveness of the controllers was examined by referring to the integral of time‐weighted absolute error value. The system was simulated using MATLAB/Simulink software. This study demonstrates that the fractional‐order PID controller achieves the most effective results, the Jaya algorithm provides the best controller parameters, and the IC technique exhibits the highest performance in MPPT.

“…The electric car market is one of the most dynamic in clean energy. Climate change, air pollution, and oil import dependency can all be addressed by electrifying transportation [11]. The promotion of NEVs can reduce the dependence of vehicles on fossil fuels and also mitigate major environmental issues such as "carbon emissions" and "greenhouse effect" [12,13].…”

Developing new energy vehicles (NEVs) is necessary to grow the low-carbon vehicle industry. Many concentrated end-of-life (EoL) power batteries will cause large-scale environmental pollution and safety accidents when the time comes to replace the first generation of batteries if improper recycling and disposal methods are utilized. Significant negative externalities will result for the environment and other economic entities. When recycling EoL power batteries, some countries need to solve problems about lower recycling rates, unclear division of echelon utilization scenarios, and incomplete recycling systems. Therefore, this paper first analyzes representative countries’ power battery recycling policies and finds out the reasons for the low recycling rate in some countries. It is also found that echelon utilization is the critical link to EoL power battery recycling. Secondly, this paper summarizes the existing recycling models and systems to form a complete closed-loop recycling process from the two stages of consumer recycling and corporate disposal of batteries. The policies and recycling technologies are highly concerned with echelon utilization, but few studies focus on analyzing application scenarios of echelon utilization. Therefore, this paper combines cases to delineate the echelon utilization scenarios clearly. Based on this, the 4R EoL power battery recycling system is proposed, which improves the existing recycling system and can recycle EoL power batteries efficiently. Finally, this paper analyzes the existing policy problems and existing technical challenges. Based on the actual situation and future development trends, we propose development suggestions from the government, enterprises, and consumers to achieve the maximum reused of EoL power batteries.

“…The other customers, thereby reducing traditional means of power generation, can also utilize the stored power [3]. The bidirectional converter for grid application is given in [4][5][6]. A typical stand-alone PV system consists of a solar module and a battery connection, thereby increasing the capital cost of the PV system as compared to the other energy sources.…”

“…The operation of a bidirectional converter is used to control the charging and draining of the battery, which may be utilized in electric car charging stations for battery charging. The number of ways is reported in [5,[7][8][9]. The solar PV system can be utilized as one of the best renewable power generators if controlled properly.…”

A novel control strategy for a single grid-connected PV system with power backup in different modes of operation, including constant load, changing atmospheric circumstances, and load variable conditions. The proposed controller works with a large nonlinear load under different modes of operation. The controller operates in such a way that, it can achieve different functions such as maintaining power flow between the photovoltaic (PV) module to the grid, maintaining UPF (unity power factor) at the point of common coupling(reactive power compensation), synchronizing a grid with PV (grid current harmonics compensation) and regulates the operation of battery(charging or discharging) for electric vehicle application. Implementing the proposed controller reduces the complexity of the active shunt filter at the point of common coupling (PCC). A maximum Power Point (MPPT) controller, optimized with perturb & observe (P&O)algorithm is used to get optimum power from the PV module. Thesimulation findings validate the operation of the suggested controlstrategy in a grid-connected PV system with a battery backup topology.
