In view of the problem that the existing researchs on the optimal scheduling of flexible load in residential buildings does not fully consider the correlation characteristics of different devices due to functional complementarity and user habituality in the use time law
resulting in a large deviation between the calculated value and the actual value of optimization scheduling
a model considering load correlation is proposed for the optimal scheduling of flexible loads in residential buildings. The model
aimed at economic efficiency
was then solved using the CPLEX solver under three different scenarios: that consideriing only temporal overlapping load correlation (scenario 1); that considering temporal order load correlation (scenario 2); and that considering both types of load correlation simultaneously (scenario 3). The results show that: in the load set of common residential buildings with correlation characteristics
the various loads in the cooking load set have temporal overlapping and temporal order load correlations
while the various loads in the domestic hot water load set and the laundry load set only contain the temporal order load correlation. In addition
compared with the results of flexible load optimization scheduling without considering load correlation
the increase proportions of users' electricity costs in scenarios 1
2 and 3 are 0.00%
7.57% and 7.57%
respectively
which shows that the timporal order load correlation characteristics cannot be ignored because they have a great influence on the optimal scheduling results of flexible load.
