Load management involves reduction of load in response to emergency and/or high price conditions. Such conditions are more prevalent during peak load or congested operation. Reduction initiated by the consumer is usually referred to as demand response. Nonemergency demand response in the range of 5% to 15% of peak load can provide substantial benefits in reducing the need for additional resources and lowering real-time prices [15]. Demand response does not substantially change the total energy consumption since a large fraction of the energy saved during load curtailment is consumed at a more opportune time thus a flatter load profile.
