Islanding in a Smart Grid Environment – a Case Study

One of the most common challenges in the energy network industry from the last decade has been the implementation and utilization of renewable energy sources. On one hand, renewable sources are the future solution from a sustainability point of view. On the other hand, there are many open questions present in the daily operation and system integration. Especially in continental Europe, it is a complex and nondescript task to operate a quasi-independent separable network area while it is connected to the large synchronous network due to regulations. Here a Hungarian living lab will be introduced where several renewable based technologies are implemented. Based on numerical and simulation methods a reliable continuous island operation will be analyzed while sizing and operation suggestions are also being defined. Using the given topology and ongoing new device installations which are changing the production and consumption portfolio, a stable and reliable architecture suggestion is given as a result. The advised solution is planned to be commissioned in the living lab respecting technical, regulatory and economic boundaries.
