Improved Fractional Order VSS Inc-Cond MPPT Algorithm for Photovoltaic Scheme

Abstract

Nowadays a hot topic among the research community is the harnessing energy from the free sunlight which is abundant and pollution-free. The availability of cheap solar photovoltaic (PV) modules has to harvest solar energy with better efficiency. The nature of solar modules is nonlinear and therefore the proper impedance matching is essential. The proper impedance matching ensures the extraction of the maximum power from solar PV module. Maximum power point tracking (MPPT) algorithm is acting as a significant part in solar power generating system because it varies in the output power from a PV generating set for various climatic conditions. This paper suggested a new improved work for MPPT of PV energy system by using the optimized novel improved fractional order variable step size (FOVSS) incremental conductance (Inc-Cond) algorithm. The new proposed controller combines the merits of both improved fractional order (FO) and variable step size (VSS) Inc-Cond which is well suitable for design control and execution. The suggested controller results in attaining the desired transient reaction under changing operating points. MATLAB simulation effort shows MPPT controller and a DC to DC Luo converter feeding a battery load is achieved. The laboratory experimental results demonstrate that the new proposed MPPT controller in the photovoltaic generating system is valid.

Fractional Order Control of Power Electronic Converters in Industrial Drives and Renewable Energy Systems: A Review

“…Some of the common MPPT strategies are Perturb and Observe (P&O), Incremental conductance (INC), soft computing techniques such as fuzzy control, Artificial Neural networks, Genetic Algorithms etc., [99]. Recently, fractional order methods have been incorporated into the conventional MPPT techniques and are seen to be very effective due to their robustness to non-linearities and transients.…”

“…In fuzzy controller proposal, one should detect the foremost control variables and regulate the sets that define the values of individually linguistic variable. The developed P&O searching algorithm is calculated to attain the merits of conventional P&O simplicity and eradicate all aforementioned disadvantages [18] [19]. The change in photovoltaic output voltage and the change in photovoltaic array output power are the two input of the modified FLC approach.…”

“…As the designed technique always transfers extreme power from photovoltaic arrays, it enhances the number of photovoltaic modules. The designed system is instigated in real-time using microcontroller board [19].…”

“…The perturb and observe method is widely applied in MPPT due to its simple structure, little parameters requirement, then not requiring solar panel characteristics [1][2][3][4][5]. It operates by periodically perturbing the instantaneous terminal voltage then comparing the output power with the pervious perturbation cycle.…”

“…Renewable energy sources are considered as an important source of energy in the twenty first century that is in use to fulfil our needs and growing demands of electricity. Among all natural energy sources, solar energy is more attractive, because it is easy to obtain anywhere and anytime through-out of the day and do not contribute global warming [1]. The extraordinary diffusion of solar PV system in electricity generation is evident from the fact that the PV scheme is anticipated to be the largest source of electricity generation among all the accessible renewable energy sources [2].…”
