Abstract

This paper presents a distributed energy management system (DEMS) for stand-alone photovoltaic(PV) system with storage devices. Usually, batteries can be used as the storage device for PV system to compensate PV output power changed by irradiation and temperature. Recently, Ultracapacitor has been adopted for the better dynamic characteristic of a whole system. The control of these systems, called hybrid system, often is complicated and need to design a proper energy management system(EMS). DEMSs are more effective than conventional centralized EMS, but it is difficult to design the DEMS for a power system because of various states of the system during operation of stand-alone mode. To verify the performance of the proposed DEMS, the stand-alone photovoltaic(PV) system is designed by Matlab/SimPowerSystems and Matlab/StateFlow tool is used for designing the proposed DEMS.
