Abstract
In this paper a DC Bus micro grid with multiple renewable sources is modelled with voltage stability control. Optimal power generation and sharing of PVA and wind farm is controlled with feedback loop modulation index control system. The micro grid can be extendable with more source other than PVA and wind. Controlled rectifiers are connected to three phase AC sources controlling the DC voltage output of the source. The three phase rectifiers are controlled with traditional Sinusoidal PWM technique. The reference sinusoidal signals are generated by SRF method with grid voltage synchronization. The modelling is carried out in MATLAB software with Simpowersystems toolbox and graphs are generated using GUI tool with respect to time.
