When a microgrid is mainly supplied by renewable energy sources (RESs), the frequency deviations may deteriorate significantly the power quality delivered to the loads. This paper proposes a frequency-based control strategy, ensuring the frequency among the strict limits imposed by the Standard EN 50160. The frequency of the microgrid common AC bus is(More)
The advances in distribution system automation, smart metering and exploitation of microgrids call for the adoption of more flexible options for power flow calculation. This paper illustrates the structure of a tool implemented to deal with time-dependent and uncertain data, as well as changing network structures during time. The focus is then set on(More)
This paper addresses the problem of quantifying the amount of spinning and non-spinning load-following reserves required for the normal operation of a power system under high wind penetration. A two-stage stochastic optimization problem is formulated; in the first stage the market operator clears the dayahead market, while in the second stage the real-time(More)
