The analog section is designed on the basis of an equivalent solar cell model while the digital section is constructed realizing the mathematical representation of the array. Fast time responses achieved by the analog section make this part suitable for the study of transient phenomena associated with the interconnected operation of PVs and the utility grid. Its digital counterpart is more appropriate for long-term experimental investigations due to its inherent accuracy and reliability. The combined hybrid simulator offers a versatile and flexible piece of apparatus capable of simulating the performance of any PV array under a variety of operating conditions. The device can be constructed with low-cost components in a compact arrangement offering transportability and ease of operation. Experimental results derived from a laboratory constructed prototype match closely the theoretically computed characteristics.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Energy Conversion, IEEE Transactions on2EC-2227-231 Vachtsevanos, G.J Kalaitzakis K.C IEEE Power & Energy Society Institute of Electrical and Electronics Engineers Analog-digital conversion Photovoltaic cells Photovoltaic energy systems Photovoltaic facilities Photovoltaic power plants Photovoltaic solar generating plants Power plants, Photovoltaic Power systems, Photovoltaic photovoltaic power systems photovoltaic energy systems photovoltaic facilities photovoltaic power plants photovoltaic solar generating plants power plants photovoltaic power systems photovoltaic Power system reliability Solar energy Solar power generation Solar radiation Steady-state Temperature Testing
