1. A peak load management system, comprising:

  • a battery system configured to store power and discharge stored power;

    a measurement system configured to measure actual load; and

    a peak load management controller operatively coupled with the battery system and the measurement system and configured to receive actual load data from the measurement system, detect malfunctions in determining actual load, compare an effective load and a target peak load and regulate a discharge of stored power from the battery system based at least in part on outcomes of comparisons of the effective load and the target peak load, wherein the management controller is further configured to use actual load as the effective load in first comparisons of the effective load and the target peak load and, in response to detecting a malfunction in determining actual load, substitute a predicted load for actual load as the effective load in second comparisons of the effective load and the target peak load, wherein the management controller is further configured to detect recoveries from malfunctions in determining actual load and, in response to detecting a recovery from the malfunction, substitute actual load for the predicted load as the effective load in third comparisons of the effective load and the target peak load.
