“…That MPPT controller was used in the off-grid application; moreover, it yields a THD of 1.41%. Niraimathi and Seyezhai (2020) proposed a Modified Grey Wolf Optimization-based PI controller with a PWM technique (MGWO–PI–PWM) controller for asymmetric cascaded multilevel inverter to produce 21-level inverter output. That proposed architecture consists of 12 switches and 3 sources, which is tested under PI-genetic algorithm and PI-particle swarm optimization in terms of THD.…”

“…That MPPT controller was used in the off-grid application; moreover, it yields a THD of 1.41%. Niraimathi and Seyezhai (2020) Grid connected hybrid solarwind system proposed a Radial Basis Function Network-based single MPPT controller for tracking the peak power from a hybrid solar-wind system which yields 587 W power during the 0 to 0.3time duration.

“…A three-tier process does the response time to make a maximum power because of the three-level variations at the input for both RES. The first tier occurs between 0 and 0.4 s, (Niraimathi and Seyezhai, 2020) 7.2 PI-GA (Niraimathi and Seyezhai, 2020) 4.8 PI-MGWO (Niraimathi and Seyezhai, 2020) 6.51 PWM (Odeh et al, 2021) 16.71 SPWM (Raj et al, 2020) 37.46 ROA_Bi-LSTM (proposed) 0.88 second-tier between 0.4 s and 0.6 s and the last one between 0.6 s and utilized simulation time. The maximum power at the first tier is achieved within 0.25 s; similarly, for the second tier, it takes 0.2 s, and for the third tier, it takes approximately 0.425 s. The average response time taken by the proposed controller for the power tracking is 0.291 s, whereas, for tracking the maximum power, FLC-MPPT takes more time to reach the maximum power with a low convergence speed.…”

Purpose Renewable energy sources such as solar photovoltaic (PV) and wind are ubiquitous because of their lower environmental impact. Output from solar PV and wind turbines is unstable; hence, this article aims to propose an effective controller to extract maximum available power. Design/methodology/approach By focusing on the varying nature of solar irradiance and wind speed, the paper presents the maximum power point tracking (MPPT) technique for renewable energy sources, and power regulation is made by the novel inverter design. Moreover, a DC–DC boost converter is adopted with solar PV, and a doubly fed induction generator is connected with the wind turbine. The proposed MPPT technique is used with the help of a rain optimization algorithm (ROA) based on bi-directional long short-term memory (Bi-LSTM) (ROA_Bi-LSTM). In addition, the sinusoidal pulse width modulation inverter is used for DC–AC power conversion. Findings The proposed MPPT technique has jointly tracked the maximum power from solar PV and wind under varying climatic conditions. The power flow to the transmission line is stabilized to protect the load devices from unregulated frequency and voltage deviations. The power to the smart grid is regulated by three-level sinusoidal pulse width modulation inverter. Originality/value The methodology and concept of the paper are taken by the author on their own. They have not taken a duplicate copy of any other research article.

Over the years, multi-level inverter (MLI) usage has increased widely for several applications like motor drives, renewable energy source- (RES-) fed grids, and electric vehicles (EVs). In recent scenarios, the development of RES, grids, and EVs is in advanced mode, and this became the reason for innovations in recent MLI topologies. The new topologies have more advantages, unique features, and abilities to meet the advanced requirements. Therefore, these new topologies are preferable for recent applications. In this paper, a detailed review of recent MLI topologies, controllers, and PWM techniques is done by considering some physical aspects as well as some performance aspects. Also, the particular focus is on the MLI topologies, controllers, and PWM techniques for photovoltaic (PV) system-fed grids and microgrids to provide details for selecting the suitable MLI topology and PWM technique for PV systems. The detailed analysis of each topology is discussed for categorizing specific applications along with futuristic expansion aspects. The future research scope on MLI topologies for PV systems is summarized with appropriate comprehensive comparisons along with their unique features over other topologies. Also, the advanced controllers and PWM techniques are also discussed with advantages and their wide range of controlling abilities.
