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...
متن کاملMaximum 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...
متن کاملA 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 ...
متن کاملGlobal Maximum Power Point Tracking of Photovoltaic Array under Partial Shaded Conditions
Efficiency of the PV module can be improved by operating at its peak power point so that the maximum power can be delivered to the load under varying environmental conditions. This paper is mainly focused on the maximum power point tracking of solar photovoltaic array (PV) under non uniform insolation conditions. A maximum power point tracker (MPPT) is used for extracting the maximum power from...
متن کاملFuzzy Based Maximum Power Point Tracking in Grid Connected Pv Systems under Partially Shading Conditions
To convert solar energy more viable, the efficiency of solar array systems should be maximized. An easier approach to maximizing the efficiency of solar array systems is Maximum Power Point Tracking (MPPT). MPPT is used in photovoltaic (PV) systems to maximize the output power of photovoltaic array, irrespective of the irradiation and temperature conditions. Many conventional MPPT fails to atta...
