The power-voltage (P-V) characteristic curve of the centralized thermoelectric generation (TEG) system under nonuniform temperature distribution (NTD) exhibits multiple extreme point characteristics, and traditional maximum power tracking (MPPT) algorithm is prone to fall into local (LMPP) takes a long time track. This paper designs BP-IPSO based on back propagation neural network (BPNN) improv...
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
The presence of bypass diodes in photovoltaic (PV) arrays can mitigate the negative effects partial shading conditions (PSCs), which cause multiple peak characteristics at output. However, conventional maximum power point tracking (MPPT) methods develop errors and detect local (LMPP) instead global (GMPP) under certain circumstances. To address this issue, several artificial intelligence (AI)-b...
The need for renewable energy resources is ever-increasing due to the concern environmental issues associated with fossil fuels. Low-cost high-power-density manufacturing techniques thermoelectric generators (TEG) have added technoeconomic feasibility of TEG systems as an effective power generation system in heat recovery, cooling, electricity, and engine-efficiency applications. environment-de...
In this paper, an improved firefly algorithm (FA) was proposed for application on photovoltaic module arrays (PVMAs) with partial modules under shading so that the maximum power point tracking (MPPT) could be implemented. Firstly, a new model of high voltage step-up converter developed executing MPPT PVMA. For energy storage inductor converter, architecture coupled adopted switch did not need t...
A two-step methodology was used to address and improve the power quality concerns for PV-integrated microgrid system. First, partial shading included deal with real-time issues. The Improved Jelly Fish Algorithm integrated Perturb Obserb (IJFA-PO) has been proposed track Global Maximum Power Point (GMPP). Second, main unit-powered via DC–AC converter is synchronised grid. To cope wide voltage v...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Kỹ thuật bám theo điểm công suất cực đại (maximum power point tracking - MPPT) là kỹ được sử dụng phổ biến trong vận hành hệ thống pin năng lượng mặt trời (PV). Trên thực tế, điều kiện bức xạ đồng nhất, có thể dễ dàng tìm ra toàn (global maximum GMPP) trên đường cong phi tuyến P-V bằng các phương pháp MPPT biến. Tuy nhiên, này rất khó dõi trường hợp nhiều địa (local LMPP) do PV bị che phủ một p...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
Solar photovoltaic (PV) is the cheapest renewable resource of electrical energy. Its dependence on connected load bounds its production capability. To deliver determined power, it required to operate at maximum power point (MPP) in characteristic curve PV array. Tracking MPP requires electronic circuits govern by tracking (MPPT) algorithms. The most simple, cheap, and softly implementable MPPT ...
