3.2), constraint equation
3.2.1) the refrigeration duty equilibrium equation
Reduce hot water and exert oneself, and then reduce the cool water quantity of centralized heat absorption formula refrigeration machine preparation, the power not enough at supply side cold water is Δ h (t), and its expression formula is following:
Δh(t)=H
CHP(t)-h
CHP(t); (3)
H wherein

CHP(t) exert oneself for the draw gas heat of condensing-type cogeneration units of the fire coal of regulating the back t period;
T period cogeneration of heat and power Cold water supply deficiency is organized by each user and is used air-conditioner power consumption refrigeration to obtain, because the time delay of cold water transmission, also there is time-delay in the influence that cold water is not enough, and this time-delay is organized the variation of distance along with the user and changed.For example, all users are divided into approximate 0,1; .., l ..; L user's group, for the 1st user group, the time that cold water flows to it is a unit scheduling duration; So the hot water deficiency also will have influence on the 1st user group in the t+1 period, in like manner, the hot water deficiency will have influence on l user's group at t+l.In sum, t period cogeneration of heat and power hot water supply deficiency will be by the air-conditioner of 0~L user group, respectively in that t~(t+L) period compensates through electricity consumption.Concrete formula is:
(T≤t+l≤2T) (4)

EHP(t+l is the t+l refrigeration work consumption sum of l group user air-conditioner constantly l), and unit is MW; h
EHP(t is the t refrigeration work consumption sum of l group user air-conditioner constantly l), and unit is MW;
If h in the formula
EHP(t l) can get 0, and on the one hand, some period, not all user's group was all participated in compensation; On the other hand, if surpassed the total activation time of regulation, the Cold water supply deficiency does not have influence on the user's group that is in far-end yet, and these user's groups also will not participated in compensation so.
3.2.2), the thermoelectric unit constraint of extraction condensing type:
