ABSTRACT
Demand Response (DR) is usually referred to as timely shifting of electrical load from high demand and expensive power price hours to lower demand and more affordable hours, or alternatively momentary changing of load in order to maintain the balance of generation and demand in a power system. The shifting can either be postponing or preponing of the demand, and in most cases the total energy usage mostly stays unchanged. Load curtailment is a special case of DR, where load is temporarily disconnected without any pay-back period, i.e., the function of the energy use is totally lost.
