Assume that a 10kW air conditioner would run 75% of the time during the peak hour and might be limited by utility remote control to a duty cycle 0f 60%.Determine the following (a) The number of minutes of operation denied at the end of 1 hr of control of the unit. (b) The amount of reduced energy consumption during the peak hour if such control is applied simultaneously to 100,000 air conditioners throughout the system. (c) The total amount of reduced energy consumption during the peak. (d) The total amount of additional reduction in energy consumption in part (c) if T&D losses at peak are 8%.
