Reactive Power- and Voltage Regulation in Micro Grids

Abstract

This paper is a continuation of the paper Examination Of Micro Grid Operation In Island Condition, Focusing On Voltage Control [10]. It has presented the assessment of micro grids’ voltage and reactive power control. The increasing integration of intelligent energy distribution networks has to serve the interest of the consumers. Therefore it is necessary to examine the quality of the electricity supply with regard to the voltage quality as well. How is it possible to ensure the regulation in those cases e.g. in case of island operation. In the paper the model developed and used for simulating the micro grids is introduced, and it is also shown, how to apply them for island operation assessment. With the help of a model network the results of the simulations are presented and the conclusions are evaluated
