Abstract: A power management and load shedding method and system comprises the steps of: a) Calculating a reserve power, RP as: RP=APT?APh?GPT where APT is a total generation capacity of a plurality of running generators in a power system, APh is a highest capacity of any one of the running generators, and GPT is a total current generated power from the running generators; b) if the reserve power, RP, is negative, generating a load shedding list identifying one or more loads of the power system to be shed substantially simultaneously, such that a total power consumption of the loads in the load shedding list is equal to or greater than a deficit in the reserve power, RP; c) storing the load shedding list in a buffer; substantially continuously repeating steps a) to c); and shedding the loads identified in the load shedding list stored in the buffer on detection of a failure of any one of the generators.
