The produced power from Photovoltaic system is varied and its efficiency is severely affected by many factors such as irradiance and ambient temperature. To obtain a competent system with maximum benefits, the tracking of the maximum power point became mandatory. This paper presents an efficient design of maximum power point tracking â€œMPPTâ€ for PV system control using three advanced techniques; PSO, Perturb- and-observe (P&O) and Incremental Conductance (I_C). The PV system based MPPT has been modelled and simulated using MATLAB/SIMULINK. The results are studied, analyzed and compared to the three proposed algorithms. PSO proved higher tracking power, lower power loss, high tracking speed, less time and minor oscillation than the other two techniques.

“…In [5][6][7], MATLAB-Simulink is used to establish a simulation model of photovoltaic array under the shadowing condition and concluded that the output of the PV array exhibits a multipeak and stepped shape under the shadow condition. In [8], it is concluded that hot spots occur when the short-circuit current of the photovoltaic cells is smaller than the electric current flowing through the cells based on the simulations and experimental studies of the reverse Bishop model of photovoltaic arrays.…”

The outdoor operating photovoltaic arrays have two different shading conditions, shadowing and covering. The shading causes a decrease in output power of photovoltaic system and may bring hot spots which causes physical damage to the array. This paper studies the electrical parameter distribution feature of photovoltaic array under different shading conditions by means of analog simulation and empirical testing. Through introducing theoretical computational method of the electrical parameters, it describes the distribution features of the electrical parameters of photovoltaic array. The results indicate that the influence of local shadowing on the current of array can be neglected. Shadowing decreases the optimal operating voltage while covering leads to a decrease in the optimal operating voltage and the open-circuit voltage. The drop magnitude of voltage is associated with the number of the shaded cell strings and the string voltage. The two shading types can be identified on the basis of distribution rules of open-circuit voltage and optimal operating voltage. Simulations and experiments verify the consistency of the rules. Relevant conclusions provide a reference for modeling, online fault diagnosis, and optimization design of the maximum power tracking algorithm of photovoltaic array under different shading conditions.

Maximum power point tracking (MPPT) algorithms are very important for the PV systems because they attract the points of maximum power at any conditions of the varying temperature and irradiation and subsequently decrease the PV array cost. This paper presents an improved MPPT technique for the PV system using particle swarm optimization (PSO) algorithm comparing with the conventional MPPT methods using perturb and observe (P&O) and incremental conductance (I_C). MATLAB simulations are carried out under the same irradiation and temperature and a variation in the load and comparing the performance of the three methods. In Protues 8.3 professional software, a design of the proposed model using Arduino UNO of the three algorithms is achieved. One of the important contributions of this paper is the proposed experimental work which is carried out by the combination of Arduino UNO which is coded by C language and coupled with MATLAB results which obtained by the simulation for the used different optimization methods in this paper. At the end of this paper, there is a comparison in tabular form between the presented 3 optimization methods with their experimental results. It is found that the results obtained by using PSO are more acceptable. The main advantages of the PSO are as follows: - it reduces the oscillations at the steady state (to approximately zero) once the MPP is located, and its algorithm is very fast comparing to the other two methods.
