Microgrids are self-contained, regional energy systems in which decentralized energy producers as well as consumers and storage systems are integrated. They form the lowest level of smart grids.
The aim of MicroGrid Güssing was to check the feasibility of a microgrid in a delimited, urban project region. Taking into account generation, consumers, network operators and storage options, a concept for a prototype application of the entire system in the project region was developed.
The analysis of the power grid in Güssing has shown that there is no immediate need for storage to ensure the stability of the grid. Assuming a continuous expansion of renewable energy producers, however, an adaptation of the power grid and the targeted use of storage facilities will be necessary.
The project results show that the activation of flexibilities has positive effects on a possible microgrid. Reductions in peak load and renewable surplus generation and thus an increase in self-consumption of renewable generation can be achieved. Furthermore, the power grid can be partially relieved. However, the results also indicate that implementing a microgrid in Güssing entails major technical and financial challenges.
