Under partial shading conditions (PSCs), multiple local maximum power points (MPPs) may be exhibited on the P-U curve of photovoltaic systems. Direct control (DIRC) methods cannot extract global MPP (GMPP); soft computing techniques can achieve it but are time consuming. This paper proposes a novel hybrid point tracking (MPPT) algorithm (INC-FA) combining incremental conductance (INC) and firefly (FA) to better adaptability in various environments. INC is widely used because its low-cost...
Under partial shading conditions, the power–voltage (P-U) curve may exhibit multiple local maxima. This makes it challenging to track global maximum power point (GMPP). Additionally, in such conventional tracking (MPPT) methods cannot be used extract GMPP. paper describes a modified firefly algorithm (MFA) that can rapidly and accurately GMPP under conditions. The introduces concepts of densities during each iteration, devises two elimination mechanisms adaptively adjust population. proposed...
Objectives. Falls in the geriatric population are a major public health issue. With anticipated aging of population, falls expected to increase nationally and globally. We estimated prevalence determinants adults aged ≥65 years calculated proportion elderly who fell made lifestyle changes as result professional recommendations. Methods. included from 2011–2012 California Health Interview Survey (CHIS) categorized them into two groups based on whether or not they had at least previous 12...
The maximum power point tracking (MPPT) based on sliding mode extremum seeking control (SMESC) in wind energy conversion system was popular for high efficiency and simple control. However, inevitably steady-state oscillation limited the scope of application method. This paper presented an improved method to maximize extracted from SMESC without oscillation. proposed replaced binary sign function by continuous sigmoid decrease simulation results were compared with traditional different speeds...
The sliding mode extremum seeking control (SMESC) could track the maximum power point (MPP) of wind energy conversion system (WECS) without speed or turbine parameters. Inappropriate SMESC parameters would cause steady-state oscillation and increase tracking time. This paper proposed an improved invasive weed optimization (IIWO) to optimize algorithm developed a new stochastic reproductive strategy enhance its robustness simplify coding. Meanwhile, IIWO optimized double coordinately replace...
