A new soft load shedding: Power system stability with contribution from consumers

The safe operation of electrical power systems is an ongoing problem. Despite the existing defense lines in the different electrical systems, they are not immune to widespread incidents leading to tripping of most consumers. In the defense plans against these major incidents, selective load shedding (LS) even optimized (but brutal), is the last resort before total blackout. This paper proposes a new concept of residential consumers "soft" load shedding (SLS). Its originality lies within the fact that it takes only a fraction of the consumers\´ power, even if the effort is spread over a larger number. It therefore seeks to avoid the plunge into darkness.
