In this method, the number of parameters to be determined is six; it consists of a current source in parallel with two diodes. The first diode simulates the diffusion process of the minority carriers into the depletion layer, whereas the second diode corresponds to the recombination in the space charge region of the junction. This model requires only the coordinates of three key points of the I-V curve, i.e., the open-circuit voltage, the short circuit current and the maximum power point. This method is applied to a set of real PV module. This method is applied to a set of real PV modules of different technology.

The main aim of this work is to design a low-cost monitoring system for the maximum power point tracking (MPPT) in a PV system. Two electronics board have been developed: a dataacquisition sensing and a DC-DC boost converter. The designed monitoring board consists of an embedded board (Arduino Mega 2560 based upon ATmega2560), current and voltage sensors, voltage regulator Mini BEC, LCD Display, and a WiFi module ESP8266 to transmit the monitored data (IPV, VPV, VL, IL and D) on the internet. In addition, a website has been also designed to store and display the monitored data in real time. The designed prototype has been verified experimentally at Renewable Energy Laboratory (REL) of Jijel University, Algeria. Based on the monitored data the users can check easily if the system works well or not by just comparing the measured output power with the one expected by a model.

Power flow control in autonomous micro-grid operation using ants colony optimization under variable load conditions

Droop control strategy is presented for accurate power sharing between parallel connected inverters in an AC micro-grid islanded mode. The controller scheme is composed of an inner current control loop and an outer power control loop based on a synchronous reference frame and the conventional PI regulators. A new control scheme based on a combination of droop control and ant colony optimization (ACO) algorithm is proposed in this paper. Droop control aims to share the load change after islanding occurs. ACO is an intelligent searching algorithm that is applied for real-time self-tuning of the power control parameters. The proposed strategy role is that the required load power is shared equally between the micro-grid and the utility based on the ACO algorithm during the load change. These are implemented using code in the Matla...
