“…Equations (10) and (11), can be re-written as Equation (12). This equation shows that the output voltage and current of the system depends directly on the duty cycle of the converter and that any change in duty cycle will lead to a change in the intersection point of I_V curve and load line.…”

Abstract:Partial shading is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. When partial shading occurs the system has multiple-peak output power characteristics. In order to track the global maximum power point (GMPP) within an appropriate period a reliable technique is required. Conventional techniques such as hill climbing and perturbation and observation (P&O) are inadequate in tracking the GMPP subject to this condition resulting in a dramatic reduction in the efficiency of the PV system. Recent artificial intelligence methods have been proposed, however they have a higher computational cost, slower processing time and increased oscillations which results in further instability at the output of the PV system. This paper proposes a fast and efficient technique based on Radial Movement Optimization (RMO) for detecting the GMPP under partial shading conditions. The paper begins with a brief description of the behavior of PV systems under partial shading conditions followed by the introduction of the new RMO-based technique for GMPP tracking. Finally, results are presented to demonstration the performance of the proposed technique under different partial shading conditions. The results are compared with those of the PSO method, one of the most widely used methods in the literature. Four factors, namely convergence speed, efficiency (power loss reduction), stability (oscillation reduction) and computational cost, are considered in the comparison with the PSO technique.

“…2. Power feedback method: (5,6) Because the voltage feedback method cannot cope with abrupt changes and perhaps fails to reach MPPT, the power feedback method is used which introduces an output power change with respect to a voltage change. When dP/dV = 0, the MPPT is accomplished.…”

This paper describes a solar energy power regulation system using solar power detectors. The system developed comprises a cubic solar power detector, DC-DC converter, three-phase inverter, and a single-chip control module. The cubic solar power detector is composed of five facets installed with front, rear, left, right, and horizontal photo sensors. By detecting solar power coming from different orientations, the solar orientation and solar power can be optimized based on a geometric transformation principle, which evaluates the relationship between photo-power and solar orientation for each sensor. Because the output power of a solar cell can significantly affect the generating capacity of the cell, a solar energy power regulation system was developed to regulate the electricity generated. The solar generating power is monitored by a cubic solar power detector and regulated by a three-phase pulse width modulation inverter. This paper describes the realization and implementation of a solar power regulation system, and experiments have been carried out to validate the performance. Measurements reveal that the system is definitely effective in regulating solar power output and can successfully boost solar power generating capacity.

“…The Perturb and Observe (P&O) method is one of the most commonly used techniques, due to its simplicity, ease of implementation, and good performance. Nevertheless, it is observed that there some power losses due to the perturbation, and that it the fails to track the power under fast varying atmospheric conditions [9]- [15]. Perturbation determines the system response and the steady state error.…”

This paper offers two Maximum Power Point Tracking (MPPT) systems for Photovoltaic (PV) applications. The first MPPT method is based on a fixed frequency Model Predictive Control (MPC). The second MPPT technique is based on the Predictive Hysteresis Control (PHC). An experimental demonstration shows that the proposed techniques are fast, accurate and robust in tracking the maximum power under different environmental conditions. A DC/DC converter with a high voltage gain is obligatory to track PV applications at the maximum power and to boost a low voltage to a higher voltage level. For this purpose, a high gain Switched Inductor Quadratic Boost Converter (SIQBC) for PV applications is presented in this paper. The proposed converter has a higher gain than the other transformerless topologies in the literature. It is shown that at a high gain the proposed SIQBC has moderate efficiency.
