A Study on the Performance of Grid-Connected PV-ECS System Considering Meteorological Variation of Bangladesh

Abstract

This paper describes the performance of a grid-connected PV-ECS system considering the variation of PV output due to the yearly
variation of solar radiation and weather condition of Bangladesh. A PV-ECS system has been considered and to study its performance a
simulation program has been developed. The validity of this simulation program has been verified by comparing the simulated results with
the practically obtained results. Two modes of operation of the PV-ECS system – (I) optimal economic mode and (II) optimal load leveling
mode have been proposed in this paper. To run the system in these modes, two different algorithms have also been developed. To study
their performance, the algorithms have been used to run the system in optimal economic mode and optimal load leveling mode. Again, the
variations of economical benefit (in mode (I)) and load leveling capacity (in mode (II)) for the change of PV output because of the yearly
variation of solar radiation and meteorological condition have been studied. Finally the economic benefits and load leveling capacity of the
simulated results have been calculated and presented here.
