IDENTIFICATION OF OPTIMAL OPERATING POINT OF PV MODULES USING NEURAL-NETWORK FOR REAL-TIME MAXIMUM POWER TRACKING CONTROL

This paper presents an application of a neural network for the identif ication of the optimal operating point of PV modules for the real time maximum power tracking control. The output power from the modules dep ends on the environmental factors such as insolation, cell temperature , and so on. Therefore, accurate identification of optimal operating p oint and real time continuous control are required to achieve the maxi mum output efficiency. The proposed neural network has a quite simple structure and provides a highly accurate identification of the optimal operating point and also a highly accurate estimation of the maximum power from the PV modules.
