A Resilience Enhanced Secondary Control for AC Micro-grids

Communication-based distributed secondary control is deemed necessary to restore the state of islanding AC microgrids to set points. As its limited global information, the microgrids become vulnerable to cyber-attacks, which by falsifying the communicating singles, like the angular frequency, can disturb the power dispatch in the microgrids...

An Adaptive Cyber Security Scheme for AC Microgrids

Distributed secondary control is deemed necessary to restore the state of AC micro-grids to set points. However, for its limited global information, the power electronic system is vulnerable to cyber-attacks that aim to desynchronize converters or even cause a shutdown of micro-grids by unnecessarily triggering the protection schemes. To this...

AC/DC and hybrid microgrid comparison for a waterpump system

In this thesis, the main objective is to argue and address the best fitting micro grid electric distribution system for a typical water-pump systems whereby the primary energy sources is renewable. So far, the grid whose main sources were wind, fossil fuel and solar energy has achieved the energy supply for the pump located at 51° 26’ 58” N and...
