PORTFOLIO MANAGED, DEMAND-SIDE RESPONSE SYSTEM

摘要

The central site 160 using grid operator requirements to reduce portfolio power according to frequency reductions within the frequency band is the optimal frequency trigger at which each load 180, 182, 184, 186 in the portfolio should reduce power. And how much power it is. The power availability of each load 180, 182, 184, 186 is optimized. These triggers and individual load power reductions are periodically dispatched from the central site to individual loads 180, 182, 184, 186. Each load 180, 182, 184, 186 detects when a frequency shift occurs and, according to the triggers, and the corresponding power reductions the load has received prior to the frequency shift, independently and It is possible to reduce quickly. There is no need to rely on the central site 160 to detect the frequency shift and then dispatch power reductions in real time. The system also detects frequency increases and instructs the portfolio of loads to consume more power. The system is generally applied to the detection of the grid signal and energy loads 180, 182, 184, 186.
