Opis:
The paper concerns the problem of local voltage instability of the power system receiving node. There were presented bases of analysis of stability margin determination using Thevenin equivalent model. Basing on Thevenin model new method of stability margin calculation was developed. The method has been described in the article. Contrary to well known methods, presented algorithm does not use a derivates of measured parameters. The algorithm uses only the measured values of steady working points. The last part of paper contains an analysis of potential errors.

Opis:
Low voltage microgrids are autonomous subsystems, in which generation, storage and power and electrical energy consumption appear. In the paper the main attention has been paid to the voltage stability issue in low voltage microgrid for different variants of its operation. In the introduction a notion of microgrid has been presented, and also the issue of influence of active and reactive power balance on node voltage level has been described. Then description of voltage stability issue has been presented. The conditions of voltage stability and indicators used to determine voltage stability margin in the microgrid have been described. Description of the low voltage test microgrid, as well as research methodology along with definition of considered variants of its operation have been presented further. The results of exemplary calculations carried out for the daily changes in node load of the active and reactive power, i.e. the voltage and the voltage stability margin indexes in nodes have been presented. Furthermore, the changes of voltage stability margin indexes depending on the variant of the microgrid operation have been presented. Summary and formulation of conclusions related to the issue of voltage stability in microgrids have been included at the end of the paper.
