“…From article, 22 the perturbation size in P&O is adjusted automatically based on the MPP location and irrespective of the change of irradiances. In this technique, when the operating point of PV at the left side of the MPP, then the duty cycle of the dc-dc converter is updated by using Equation (1). Once the operating point reaches the true MPP then the step-change in duty cycle is considered very small to reduce the oscillations across MPP.…”

“…These are the issues that make the research scholars focus on renewable sources such as solar, wind, and tidal. 1 The generation of electricity by using renewable energy sources is an important criteria to meet future electricity demand as their use does not affect the environmental conditions. The advantages of renewable energy sources are excess availability in nature, pollution free and free of cost.…”

Under partial shading conditions (PSCs), the I-V curve of PV systems consist of multiple local maximum power points (MPP's) and one global MPP which is required to extract the peak power of solar PV. In this article, an improved variable step size-radial basis function algorithm (VSS-RBFA) based MPPT controller is implemented to track the MPP with high speed. The advantages of proposed MPPT controller are high convergence speed, reduced oscillations across MPP, and takes less time to track MPP. Also, a universal high step-up boost converter (HSBC) is proposed in this work to step up the PV voltage. The attractive features of HSBC are continuous input current, high voltage gain, less voltage stress on switches, and wide input and output operation. The proposed converter continuous conduction mode (CCM) and discontinuous conduction mode (DCM) of operations are compared successfully at the steady-state operating condition. The simulation results of the proposed PV fed HSBC system is validated under uniform and PSC's of solar PV. In addition, the proposed converter results are verified experimentally by using a programmable DC source.

“…Most studies that explore complementarity to find ways to integrate different renewable resources to improve reliability on national power systems use simulation and optimization approaches. They are used to suggest ways to combine renewable resources (Moura and de Almeida 2010;Bezerra Leite Neto, et al, 2020), interconnect neighboring countries (Viviescas et al, 2019), or flatten the output of the renewable resources (Jaramillo et al, 2004). For example, in Poland, Jurasz and Ciapała (2017) developed an optimization model to reduce the variability of solar photovoltaics by combining it with a runoff power plant.…”

“…Although the increasing importance of wind energy in the global energy market (see, e.g., [1]) is mainly due to large-scale installations, Small Wind Turbines (SWTs) are also an important player in this field. This includes prosumer applications (e.g., in hybrid installations [2]), isolated sites operation (for example, to power transmitter stations or remote islands [3]), and multi-rotor array applications (a substitute for the single, big-size rotor [4]). This article presents the outcomes of a case study of an SWT fit for prosumer suburban application in European wind conditions.…”

While the vast majority of the wind energy market is dominated by megawatt-size wind turbines, the increasing importance of distributed electricity generation gives way to small, personal-size installations. Due to their situation at relatively low heights and above-ground levels, they are forced to operate in a low energy-density environment, hence the important role of rotor optimization and flow studies. In addition, the small wind turbine operation close to human habitats emphasizes the need to ensure the maximum reliability of the system. The present article summarizes a case study of a small wind turbine (rated power 350 W @ 8.4 m/s) from the point of view of aerodynamic performance (efficiency, flow around blades). The structural strength analysis of the blades milled for the prototype was performed in the form of a one-way Fluid–Structure Interaction (FSI). Blade deformations and stresses were examined, showing that only minor deformations may be expected, with no significant influence on rotor aerodynamics. The study of an unorthodox material (PA66 MO polyamide) and application of FSI to examine both structural strength and blade deformation under different operating conditions are an approach rarely employed in small wind turbine design.
