    Abstract

    This paper continues on from previous work where a grid connected inverter with ancillary functions was explained, designed and simulated. In this paper, the project will continue implementing the converter in a microgird; experiments have been conducted to evaluate the performance and fulfillment of a grid code compliant inverter. Before, the system had the capability of changing, automatically, the internal converter dynamics. Now, these functionalities have been exploited further and the it is able to adapt its response speed even when the system is already connected and injecting power to the grid. This characteristic makes the converter not only fully compliant with the most common grid codes of Spain, Denmark and the UK but also dynamic depending on the grid situation. As a result, the converter is more grid-friendly and easily customized and at the same time improves the stability of the converter itself.
