Application of photovoltaic power in systems involving intermittent loading requires an understanding of the dynamics of such systems. This paper explores this area by taking the vegetable slicing system as a typical example of intermittent loading. Bond graph methodology has been used in modelling. This method has appeared as a convenient tool in formulating dynamic models of electromechanical machinery, but has not yet been applied to study the dynamics of PV driven systems. This paper presents the first attempt in that direction. The results obtained by computer simulation are reported.
