Amid escalating concerns over global warming and climate shifts, the imperative for advanced transportation solutions intensifies, aiming to balance economic growth and environmental preservation. The worldwide upsurge in electric vehicle (EV) adoption reflects this transformative aspiration, yet relying solely on fossil fuelbased EV charging infrastructure falls short of addressing climate challenges. In response, Multi Energy Integrated EV Charging Stations have emerged as a pragmatic solution, seamlessly blending renewable energy sources, grid power, and EV charging needs. This study proposes a meticulously crafted charging station design employing Adaptive Neuro-Fuzzy Inference System (ANFIS) technology for voltage-controlled Maximum Power Point Tracking (mppt), coupled with Type 3 & 2 controllers, which collaborate in harmonious precision to streamline EV charging dynamics and Neural Network-based grid management. The design is meticulously assessed and evaluated using MATLAB/Simulink, presenting a promising avenue for sustainable and efficient EV charging infrastructure in the face of evolving energy demands and environmental concerns.

Pulse width modulation for Selective Harmonics Elimination (SHE) is mostly employed in the reduction of lower order harmonics. The PV system in this research provides input voltage to the reduced switch 31-level inverter, which is based on the Artificial Bee Colony algorithm. With a high gain DC-DC single-ended primary-inductor converter (SEPIC), the PV panel output voltage is kept constant. The Grey wolf optimization algorithm (GWO) approach is used to get the most power out PV scheme. Multi Carrier modulation, a high-frequency modulation technology, is also used in this novel design of the inverter to reduce upper order harmonics. The suggested Artificial Bee Colony (ABC) algorithm, harmonics is compared to a SHE technique based on a genetic algorithm. The hardware findings were confirmed using DSPIC30F2010 controller simulation, and the recommended system was validated using Matlab simulation.

As solar generation gains an increased importance in a smart grid, an efficient control of a photovoltaic (PV) array has to be considered. However, energy efficiency of a PV array greatly depends on environmental conditions, such as uneven shading, solar irradiance and temperature. Maximum power point tracking (mppt) algorithms aim to dynamically find an optimal operation voltage in order to compensate for changes in the environment, as well as degradation of solar panels. Besides generating a maximum amount of power, an mppt controller aims for stability in order to avoid additional losses. Reinforcement Learning (RL) is a flexible training method that can produce a controller for a complex problem without a detailed prior knowledge of the environment. In this work we propose an approach that combines an optimized neural network, trained through deep reinforcement learning (DRL), with a classical closed-loop control. Experimental results suggest that the proposed approach outperforms a recently proposed DRL network both in terms of efficiency and stability. A compact and discrete version of the proposed controller is also evaluated and shown to further increase performance. The implemented algorithms and the RL simulation environment are made available in an open-source repository. (c) 2022 Elsevier B.V. All rights reserved.

the use of renewable energy in many applications has become an important necessity due to the high price of fuel on the one hand and the great shortage of the national grid in Iraq during the past two decades. The solar powered water pump system consists of solar PV modules, submersible pump, and its control unit. Solar cells have non-linear I-V characteristics and the energy generated depends on the nature of the solar panels and the ambient temperature, and the mismatch of the source and the load leads to a decrease in the efficiency of the system. So it uses mppt to extract maximum power from the PV panel. Matlab Simulink model was used to design and analyze the PV system as well as the solar powered pump. The results indicate the ability of the mppt to extract the energy required to operate the pump.

In solar photovoltaic (PV) system applications, one of the most important tasks is to extract maximum power from PV arrays with minimum losses. Maximum power point tracking (mppt) is a commonly used method to maximize power extraction from PV systems under all environmental conditions. In this paper, a modified perturb and observe (P&O) tracking method using an interleaved DC-DC buck converter is proposed and compared with the traditional method. The proposed method uses illuminance level as the perturb signal to control the converter's duty cycle under varying solar radiation conditions. The results validate the speed and effectiveness of the method, which is centring illuminance level comparing its performance to the traditional P&O method.

A solar-powered converter design is necessary for portable devices with increased gain and reduced ripple in overall operation. This research presents a photovoltaic-powered Field Programmable Gate Array (FPGA) based on increased gain multiple output converter design and analysis. The dynamic panel input makes it difficult to operate the load. To control and make the input static to satisfy the demand, perturb and observe with a load balancing algorithm technique are used. The converter gained output is high, and batteries are used to balance the loads when solar irradiance is low. Simulation results were carried out with the presented converter circuit that can be operated with a 12 V supply as input from a renewable power source. The output gain ratio of 14 to a minimum of 40 % duty cycle operating at a switching frequency of 20 kHz has been achieved. The proposed methodology is transferred to hardware by connecting with the reconfigurable FPGA Spartan-6 development board to manage the dynamic load control system's complex logic and high processing ability. The overall performance is compared with various pre-existing systems, tabulations are made with the analysis, and experimental results are also illustrated at the end. © 2024 The Author(s)

An mppt controller model for a standalone PV system

Designing an efficient photovoltaic (PV) system is a complex task that involves modelling and simulation of all of its subsystems. The simulation results are usually obtained by performing behavioural simulations, which is useful when simulating at the system level, though it is not possible to implement models of real electronic components due to an absence of adequate libraries. In this manuscript we will focus on a simulation of electronic circuits performing maximum power point tracking control (mppt), which is one of the standalone PV subsystems, using circuit-level model. Here we will introduce some modifications to perturb and observe method in order to facilitate circuit-level simulation, and present a SPICE circuit implementing that mppt algorithm. The importance of the contribution comes from the fact that the SPICE implementation of the algorithm is circuit (technology) independent.
