DEVELOPMENT OF MATHEMATICAL MODELS FOR INVESTIGATION OF MAXIMAL POWER POINT TRACKING ALGORITHMS
D. Vasarevičius, M. Pikutis
Abstract
Solar cells generate the maximum power only when the load is optimized according insolation and module temperature. This function is performed by MPPT systems. While developing MPPT, it is useful to create a mathematical model that allows simulation of different weather conditions, affecting the solar modules. Solar insolation, cloud cover imitating and solar cell models were created in Matlab / Simulink environment. Comparing simulation of solar insolation on a cloudy day with the measurements made with pyrometer it is found that the model generated signal changes according similar laws as real life signal. Model can generate the solar insolation values in real time, what is useful in predicting the amount of electrical energy produced from solar power. Model can operate with the use of stored signal, so comparisons of different MPPT algorithms can be provided.
Keywords: solar power, solar cells, solar power, MPPT algorithms.
