An Efficient Fuzzy-Logic Based Variable-Step Incremental Conductance MPPT Method for Grid-Connected PV Systems

Abstract: Recently, solar energy has been intensively employed in power systems, especially using the photovoltaic (PV) generation units. In this regard, this paper proposes a novel design of a fuzzy logic based algorithm for varying the step size of the incremental conductance (INC) maximum power point tracking (MPPT) method for PV. In the proposed method, a variable voltage step size is estimated according to the degree of ascent or descent of the power-voltage relation. For this purpose, a novel unique treatment is p… Show more

“…Further, Table 2 shows the lower and upper bounds of the decision variables of the model at two different operating condi-tions, (operating condition #1: 1/1 bar and 343.15 K) for both stacks (250 W and NedStack PS6) and (operating condition #2: 3/5 bar and 353.15 k) for 250 W stack. The simulation results have been compared to other literature works [18][19][20][21][22]. Moreover, four competitive methods; SSA [46], SCA [47], MFO [48], and PSO [16] have been implemented to test the effectiveness of COA.…”

“…A PEMFC is considered one of the most promising devices that convert chemical energy fuels into electrical energy based on electrochemical responses [15][16][17][18]. Specifically, the PEMFCs have numerous rewards, e.g., good electrical efficiency, little emission, and flexibility in fuel, that make them applicable to diverse applications [20][21][22][23][24]. For instance, they can apply in the combined tough issue owing to PEMFC being a compound multivariable powerfully coupled scheme.…”

“…In the literature, many research papers have been directed to blade pitch control of WECS interconnected to power systems. It is a fact that modeling of the suitable blade pitch control scheme is the major requirement for WECS to preserve the power generated from the wind turbine at its highest value while improving aerodynamic characteristics [9], [10]. However, it is a challenging task to build a comprehensive WECS dynamical model due to the highly fluctuated profiles and nonlinearity [11].…”

“…ESS is charged during sunlight hours when PV power exceeds load demand, while during peak times, shortages of power generation, or unstable generation of PV, ESS discharge their energy [26][27][28]. The PV systems are widely operated in two modes of operation: stand-alone and grid-connected modes [29][30][31][32][33]. During the stand-alone mode, ESS compensates for the shortage of power generated by the PV modules, and if the stored power was insufficient, the system undergoes load shedding to meet the system requirements [34].…”
