Supplying a Direct Current Electricity to the Isolated Dwellings through MPP Tracked PV System Based on Artificial Neural Network

Abstract

The difficulties of the grid electricity supplying to certain locations like far, high lands, or countryside leads to concentrate on the solutions of the renewable photovoltaic stand-alone system supported by an efficient maximum power point tracker. In addition, the difficulties of the alternating current system which are represented by a complicated controller, system size, and high cost due to the necessity of involving an inverter, a high order filter and a step up or an insulation transformer. From this point of view, this paper presents a new solution of 10.8 kW PV system which combines between the high performance of the MPPT controller and the avoiding of the alternating parts by considering direct current home appliances. A study of loads' power requirements, PV matrix design of an isolated dwelling, a full electronic design of a DC-DC boost converter with a fast response MPPT controller based on an Artificial Neural Network (ANN) which is followed by Proportional Integral (PI) controller all are presented in this paper. The simulation results are collected through MATLAB/Simulink, and the system performance is evaluated and indicated the high effectiveness in terms of harvested power.

Artificial neural network based unity power factor corrector for single phase DC-DC converters

“…The width of the PWM pulses can be controlled based on ANN predicting to the duty cycle which is required to compensate the phase shift between the grid voltage and the grid current. Based on the fact of that the artificial neural network ANN can quickly predict the suitable numerical value by considering the instantaneous numerical values of the input variables of the related system's parameters [16][17][18]. So, a new ANN algorithm has designed in this paper to predict the suitable duty cycle to have 100 percent matching between the grid voltage and grid current that consequently lead to have unity PF.…”
