Energy generation is facing a big challenge for meeting the load demand during peak hours. Power utilities are heavily depending on fossil fuels due to limited resources of non renewable energy generation. Therefore researchers and scientists are looking towards some distributed generators (DGs) to supply extra power during peak hours of energy curve. Solar power gives them an extra sniff to meet the load demand in that period. As a consequence grid-tied solar Photovoltaic (PV) system catches the eyes of researchers and industrialist mainly for reducing the burden of fossil fuel energy generation. Single stage or two stages PV systems are applicable for grid interconnection with or without battery backup. Double stage system is generally suggested for practical applications as it holds a benefit of power quality improvement. This article presents a comprehensive review on grid-tied solar PV system. The complete architecture of the grid-tied PV system includes the construction of PV array, MPPT methods, DC-DC converters, Inverters and control algorithms. Different control techniques and topologies with their merits and demerits for grid-tied systems are thoroughly reviewed. The comparisons of different conventional and advanced control techniques justify the practicability of this architecture. Different topologies and control methods of grid-tied PV system are studied thoroughly to justify the potential of grid-tied PV system.

“…The amount of power actively injected into the main grid from the PVG is determined by the PV-DC source block output voltage and current. The MPPT control circuit is an important part of the PV-DC source; its objective is to set up the PV arrays output reference voltage corresponding to the PV maximum power [3][4][5]. The inputs of the MPPT controller are the output voltage and current of the PV-DC source block.…”

“…In these, solar energy seems more popularly exploited because of its advantages. The structural model of a photovoltaic (PV) system was presented in [1,2], and strategies for extracting power from PV systems at maximum power point operation were introduced in [3][4][5]. The PV system is an important module of a PV generator (PVG), acting as a primary energy source.…”

Abstract:In this paper, a general design method for multifunction converters using photovoltaic systems is proposed.With the proposed converter, the photovoltaic generator can provide flexibility, accuracy, and fast responses in both harmonic suppression and power injection modes in all cases of the grid-connected load. The controller for the proposed converter is designed based on the Lyapunov technique, along with the generalized algorithm for determining the global optimal values of the stability bounds. Therefore, the proposed converter can perform accurately and efficiently in the case of fixed system parameters as well as in the case of varying system parameters. Simulations and experimental results are presented to validate the accuracy and effectiveness of the proposed model and control strategy.

“…However, this method needs to search many points to find the GMPP, which is time-consuming. A method that uses Fibonacci search algorithm to find the GMPP is proposed in [4], which reduces the number of the searching points. However, this algorithm is complicated and could be difficult to implement.…”

Abstract. In a photovoltaic (PV) system that consists of multiple series-connected PV modules with bypass diode, multiple peak points could exist in the P-V curve of the PV system under partially shaded conditions (PSC), causing conventional MPPT methods sometimes unable to track the true global maximum power point (GMPP). In view of this problem, we propose in this paper a new two-stage global maximum power point tracking (GMPPT) method based on the distribution characteristic of the GMPP voltage and the dividing point voltage. The method proposed finds all the possible peak power points and compares the power of those points to find the GMPP in the first stage. In the second stage, the method sets the operation point to the point of the maximum power found in the first stage and uses the hill climbing (HC) method to keep the operation point at that point. The method proposed is validated by simulation. Simulation result shows that this method can track the GMPP effectively.
