Comparison method of MPSO, FPA, and GWO algorithm in MPPT SEPIC converter under dynamic partial shading condition

Grade point average assessment for metaheuristic GMPP techniques of partial shaded PV systems

“…Reinitialisation condition to detect the PSC change is introduced based on the change of PV power (P PV ) between iterations as shown in (7) [59] 2016 duty cycle boost converter not applicable GWO can catch the GMPP under PSC quickly and efficiently in comparison with PSO and P&O. GWO-MPPT efficiency is 99.8%, whereas PSO and P&O have an efficiency of 31.3 and 99.7%, respectively. Also, GWO has fewer oscillations around GMPP compared to others [60] 2017 duty cycle single-ended primaryinductor converter (SEPIC) converter not applicable results reveal that the three techniques (MPSO, FPA and GWO) have the possibility to catch the GMPP with a high level of accuracy. Although MPSO outperformed other techniques (GWO and FPA) in tracking accuracy, FPA is faster than others to converge GMPP [61] 2016 duty cycle boost converter not applicable GWO-based GMPPT technique outperforms both P&O and IPSO in terms of GMPPT efficiency, steady-state oscillations and transients flashes are to attract mating partners and potential prey.…”

Applications of Flower Pollination Algorithm in Electrical Power Systems: A Review

“…The devastating effects of global warming are becoming more evident, the excessive use of fossil fuels as a means of energy generation identified as one of the primary contributors to the thinning of the ozone layer and the diminishing resources of hydrocarbon deposits the world has turned to more sustainable renewable forms of energy generation [66,83,84]. The use of renewable energy sources is not perfect, in that their reliance upon specific weather conditions to ensure optimal efficiency are one of their key drawbacks [66], [83], [84]. One of the solutions to the low efficiency rates of DG units are the inclusion of maximum power point trackers (MPPT) which allows for the maximum power to be extracted irrespective of unpredictable weather conditions [66], [83], [84].…”
