TL;DR: In this paper, two possible control strategies were investigated and are described in order to operate a microgrid under emergency mode, and a sequence of actions for a well succeeded black start procedure, involving microgeneration units, has also been identified contributing for an increase in distribution network reliability.
Abstract: Under normal operating conditions, a microgrid (MG) is interconnected with the medium voltage (MV) network. However, planned or unplanned events like maintenance or faults in the MV network, respectively, may lead to MG islanding. In order to deal with islanded operation and even black start following a general blackout, an emergency operation mode must be envisaged. Two possible control strategies were investigated and are described in this paper in order to operate a MG under emergency mode. A sequence of actions for a well succeeded black start procedure, involving microgeneration units, has also been identified contributing for an increase in distribution network reliability

Abstract: Most experts agree that the major blackout that affected a large part of the North American upper Midwest and Northeast last August 14, 2003, was no anomaly and will definitely happen again. Records show that between 1984 and 2000, utilities logged 11 outages affecting more than 4000 megawatts, making the probability of any one outage 325 times greater than mathematicians would have expected. Mathematicians, engineers, and physicists have set out to explain the statistical overabundance of big blackouts. Two distinct models emerged based on two general theories of systems failure. One, an optimization model presumes that power engineers make conscious and rational choices to focus resources on preventing smaller and more common disturbances on the lines; large blackouts occur because the grid isn't forcefully engineered to prevent them. The other model views blackouts as a surprisingly constructive force in an unconscious feedback loop that operates over years or decades. Blackouts spur investments to strengthen overloaded power systems, periodically counter-balancing pressures to maximize return on investment and deliver electricity at the lowest possible cost. The mainstream view among power system engineers continues to be the answer to reliability problems is to make the grids more robust physically, improve simulation techniques and computerized real-time controls, and improve regulation. What system theorists suggest is that even if all that is done and done well, the really big outages still will happen more often than they should.
