Abstract
Microgeneration technologies, such as small-scale wind turbines, fuel cells and Photovoltaics (PV) arrays, connected to low-voltage distribution networks offer the potential to reduce carbon emissions, to improve security of supply and to contribute significantly to the energy mix. Many types of microgeneration technologies are interfaced with the low-voltage distribution network through power electronic converters. The converter provides conversion of the microsource frequency to the conventional power system frequency of 50/60 Hz and controls the power exchange between the generator and the load/utility system Therefore; new control methods for these converters need to be developed in order to exploit the microgeneration as effectively as possible when connected to the network. This paper presents analysis and design of microsources DC current control with considering reactive power control, power factor control and voltage regulator. The objective is to show that with an adequate control the converter can transfer the dc energy from microsource and improve the voltage stability and power quality of the electrical system. Also it can protect the inverter from over current and the microsource from overload. The feasibility of the proposed control schemes was verified by a digital simulation in PSCAD/EMTDC software program.
