Maximum Power Point Tracker for Photovoltaic Systems Based on Moth-Flame Optimization Considering Partial Shading Conditions

The performance of photovoltaic (PV) systems is highly dependent on environmental conditions. Due to probable changes in environmental conditions, the real-time control of PV systems is essential for exploiting their maximum possible power. This paper proposes a new method to track the maximum power point of PV systems using the moth-flame optimization algorithm. In this method, the PV DC-DC co...

A Novel Algorithm to Find Maximum Power Point for Solar Systems under Partial Shading

In this paper, a new two-stage control algorithm to reach the maximum power point in photovoltaic (PV) systems under partially shaded conditions is presented. This algorithm tracks the maximum power point without any need to measure the open circuit voltage, short circuit current and making use of any extra switches. To achieve maximum power performance, the method firstly selects the relevant ...

An Improved Photovoltaic Array Configuration for Photovoltaic System in the Presence of Maximum Power Point Tracking during Partial Shading Condition

Power-Voltage (P-V) curve and Current-Voltage (I-V) curve determine the performance of the PV system. In this work, the arrangements of the PV module were reconstructed by adding the number of PV module in 3 strings configuration from 5 to 45. This method enhance the performance of the PV system as it able to show the characteristic of the P-V and I-V curve during partial shading and maximum ir...

A Fast and Accurate Global Maximum Power Point Tracking Method for Solar Strings under Partial Shading Conditions

This paper presents a model-based approach for the global maximum power point (GMPP) tracking of solar strings under partial shading conditions. In the proposed method, the GMPP voltage is estimated without any need to solve numerically the implicit and nonlinear equations of the photovoltaic (PV) string model. In contrast to the existing methods in which first the locations of all the local pe...
