 Abstract:

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
