The integration of distributed generation (DG) in the electric network presents a challenging task for grid operators. While DGs can be considered beneficial for the environment since they are powered by renewable energy sources, unwanted effects on power quality, equipment and personnel safety, and power system protection can be seen when these generators are in service. A solution to these problems is to group distributed generation and the loads into small network clusters called microgrids. A microgrid is a group of energy sources and loads operating semi-independently of the external grid (or the macrogrid) . The microgrids are seen by the power system as a single, controlled unit that is behaving either as a load or source. For the customer and the utility, the microgrid can be tailor-made to perform a number of tasks such as enhancing reliability, optimizing the use of renewable energy, improving voltage quality, etc . This paper presents the implementation, field test and simulation results of a pilot microgrid in the Netherlands. The objective is to implement a self-supporting, reliable and efficient microgrid operation.
