Abstract. This paper introduces a coordinated droop control for the stand-alone DC micro-grid., which is composed of photovoltaic generator, wind power generator, engine generator, and battery storage with SOC (state of charge) management system. The operation of stand-alone DC micro-grid with the coordinated droop control was analyzed with computer simulation. Based on simulation results, a hardware simulator was built and tested to analyze the performance of proposed system. The developed simulation model and hardware simulator can be utilized to design the actual stand-alone DC micro-grid and to analyze its performance. The coordinated droop control can improve the reliability and efficiency of the stand-alone DC micro-grid Key wordsstand-alone DC micro-grid, autonomous control, droop control, PV (photo-voltaic) generator, WP (wind power) generator, BES (battery energy storage), SOC (state of charge), MPPT (maximum power point tracking).

In the time of rapid changes in power industry the need to develop new power systems arises. The newly developed systems should aim at wide utilisation of renewable power sources and CO2-neutral technologies. This goal can be achieved by e.g. dissipated generation, or integrating DG into microgrids. The microgrids can be built using AC or DC current networks. Authors propose DC microgrid as a new idea for a small, balanced distribution power system. It has been designed to supply small towns and villages with electricity with high penetration of renewable energy resources. However, designing an optimal microgrid is not an easy task, due to the fact that primary energy carriers are changeable and uncontrollable, as is the demand. Traditional design and optimisation tools, developed for controlled power sources, cannot be employed here. Simulation methods seem to be the best solution. The microgrid consists of several devices, with most important among them -the power electronic devices.Schematic simulation tools, like PSpice, PSIM or TCad, are usually used for power electronic converters simulation. However the above mentioned simulation method is slow and does not allow modeling the microgrid's network. Therefore new models of converters have been developed. The authors employed Simulink to simulate power flow and static voltage behaviour in the microgrid. The models developed on the example of half bridge converter are presented in the paper, as is the comparison of PSIM and authors' models.The conclusion from the research is that new static and power flow models are interesting solutions for designing small power system simulation like the DC microgrid.
