چشم انداز مدیریت تقاضا در تعامل بین یک شبکه غیر ایده آل و چراغ لامپ های مسکونی

Lighting industries across the world are witnessing a rapid shift towards energy efficient LED (Light Emitting Diode) lightings. These lighting technologies can be seen as an alternative tool to the DSM (Demand Side Management) in residential, commercial as well as industrial sector. DSM has a strong linkage with the reliability and quality of power supply and any variations in supply conditions may significantly affect DSM strategies. As LED lighting technologies are penetrating the lighting market at a rapid pace, it is important to assess the different impacts of distribution grid conditions on the power quality and energy consumption performance of LEDs. This paper presents an extensive analysis of the consequences of sustained abnormal voltage, supply voltage harmonics, and supply frequency variations on LED lamps and its overall effect on the popular “LED lighting DSM Program” – being adopted worldwide. It was observed that under the variable grid conditions, some lamps’ technologies offer DSM like advantages without being actively engaged in DSM. Several parameters have been evaluated, analyzed and, recommendations have been made for LED-based passive DSM strategies which may encompass the LED manufacturers, the utilities, and the governments.
