Summary The solar power plants are playing a significant role in energy market due to its eco‐friendly nature, low operational, and maintenance cost. The efficiency of these plants depends mainly on load impedance, topology of converters, and maximum power point tracking algorithms. In this work, effect of operating point (load line selection) on the performance of maximum power point tracking for different DC‐DC converter topologies has been studied and experimentally validated. Further, the operating constraints of buck, boost, and buck‐boost modes of converter operation in terms of load impedance are presented. The performance of different maximum power point tracking algorithms under load and solar irradiance change has been investigated for all converter topologies discussed. The modified model of photovoltaic module has been presented for simulation study under different solar irradiance and load variations that can be easily implemented on Real Time Digital Simulator platform unlike conventional models.
