Load Disaggregation Based on Aided Linear Integer Programming
  Load disaggregation based on aided linear integer programming (ALIP) is
proposed. We start with a conventional linear integer programming (IP) based
disaggregation and enhance it in several ways. The enhancements include
additional constraints, correction based on a state diagram, median filtering,
and linear programming-based refinement. With the aid of these enhancements,
the performance of IP-based disaggregation is significantly improved. The
proposed ALIP system relies only on the instantaneous load samples instead of
waveform signatures, and hence does not crucially depend on high sampling
frequency. Experimental results show that the proposed ALIP system performs
better than the conventional IP-based load disaggregation system.
