First results of an aimed research carried out by the Italian PT Ministry related to a prototypical photovoltaic hybrid power system for TLC

An experimental PV (photovoltaic) plant integrated with a diesel electric generator (DEG) has been implemented in the ISPT (Istituto Superiore PT). A year and a half after its installation the first experimental phase aimed at investigating the problems related to multisubsystem assembly has been achieved. The authors report on the charge adjusting system from PV to battery, control criteria on the state of charge of battery cells, and ways of DEG intervention for an optimal energy balance to gradually introduce subsystems into the project. The second experimental phase has been performed for six months with the aim of collecting and processing data which will make it possible to check the fitness of the project with respect to wind plant integration. The philosophy of data acquisition and processing is illustrated.<
