Active management of distribution networks and different controllable resources will play a key role in future Smart Grids. This paper proposes that centralized active network management functionalities at MV level could also include an algorithm which in real time confirms reliable islanding detection with local measurements based passive method. The proposed algorithm continuously ensures tha...

In this paper, a new droop-based reactive power control strategy is proposed that is suitable for implementation in autonomous low voltage microgrids. The proposed method exploits the potentials of adding a dynamic virtual inductance loop to compensate for the voltage drop differences caused by line impedances. In addition, it provides a large virtual inductance at the output terminals of a dis...

This paper analyses the frequency support characteristics of multi-terminal VSC-HVDC (MTDC) schemes using the energy transferred from wind turbine rotating mass and other AC systems. An alternative coordinated control (ACC) scheme, which gives priority to a frequency versus active power droop fitted to onshore VSCs is proposed to: (i) transfer wind turbine recovery power to undisturbed AC grids...

This paper develops a coordination control strategy for wind farms with line commutated converter (LCC) based HVDC delivery to participate in inertia response and load frequency control. The coordination philosophy is to let the HVDC rectifier sense the grid frequency. If the grid frequency is too high or too low, active power flow through the HVDC link will be ramped down or up by introducing ...
