Several considerations, especially large scale integration of renewables in power systems require new, cheap sources of controllability to be discovered and activated to compensate for the lack of deterministic behavior. This paper discusses some asp

Because of the increased use of photovoltaic (PV) installations, new and more stringent power quality requirements are being issued. Continuous grid monitoring is always a matter to be considered in order to detect islanding operation. One of the sev
