Embedded emulator of photovoltaic array and wind driven induction generator by using digital signal controller (tms320f28335)

Modern technology has given rise to a slew of forward looking enhancements for systems that transmit and distribute electricity. Distribution networks must be carefully controlled in order to maintain an acceptable power supply quality. In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other. This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system on the combination of solar cell and wind turbine systems for power generation. Dynamic modeling of various components of this isolated system is presented. Transient responses of the system to step changes in the load, ambient temperature, radiation, and wind speed in a number of possible situations are studied. The results show that the proposed hybrid power system can tolerate the rapid changes in natural conditions and suppress the effects of these fluctuations on the voltage within the acceptable range. We designed a flexible DSP-controlled three-phase power electronic converter for the integration of distributed energy generation into networks. The further increase of energy conversion from renewable energy sources demands a share of the conventional centralized grid control. This requires a fast and flexible control system. The control is realized with embedded model details of DSC. The system structure, the special problems resulting from the use of a DSP-system and the implementation of the inverter control are described. The models have been developed by means of Simulink.
