“…In recent years, MPPT methods based on intelligent techniques such as particle swarm optimization (PSO), genetic algorithms (GA), fuzzy control, simulated annealing algorithm, neural networks and firefly algorithm have been reported [30]. Intelligent algorithms have drawbacks as complex implementation and the difficulty in initial point selection [27]. The current challenge is to introduce robust and reliable MPPT methods.…”

Complex control structures are required for the operation of photovoltaic electrical energy systems. In this paper, a general review of the controllers used for photovoltaic systems is presented. This review is based on the most recent papers presented in the literature. The control architectures considered are complex hybrid systems that combine classical and modern techniques, such as artificial intelligence and statistical models. The main contribution of this paper is the synthesis of a generalized control structure and the identification of the latest trends. The main findings are summarized in the development of increasingly robust controllers for operation with improved efficiency, power quality, stability, safety, and economics.

This review covers global maximum power point tracking (GMPPT) methods for photovoltaic (PV) systems under partial shading conditions. Unlike the previous review works that primarily focused on soft computing and hybrid GMPPT, this study gives exclusive attention to the improvement achieved by the conventional MPPT (perturb and observe, hill climbing, and incremental conductance). The improved methods include the popular 0.8 × V oc model and, more recently, the skipping algorithms. In addition to providing qualitative descriptions of the available techniques, this work also attempts to provide a fair evaluation of GMPPT to determine their comparative performances. The competing algorithms, which are selected to represent every category (conventional and soft computing and hybrid MPPT), are benchmarked under carefully selected operating conditions and shading scenarios. The evaluation is focused on four main criteria: tracking accuracy, convergence time, length of voltage fluctuations, and transient efficiency during the search for the global maximum power point. The results obtained from this study can become a basis for researchers and designers to select the best MPPT technique for their respective applications.

“…Despite the advantages of the method proposed in [17], besides using a fixed upper voltage limit, the method may fail for climatic conditions that have high temperatures and large shaded areas. Due to these facts, a technique was proposed in [18], which aims to further decrease the voltage search range by modifying the method proposed in [17]. This technique, named Modified Maximum Power Trapezium (M-MPT), introduces a variable minimum current boundary using the decreasing characteristic of the output current of the PV array, in order to reduce even more the search region.…”
