H _wSHP(t)=COP _wSHPp _wSHP(t) (7) wherein, H _wSHPfor the specified thermal capacity of water resource heat pump; COP _wSHPfor the water resource heat pump coefficient of performance; h _wSHP(t) exert oneself for the heat of water resource heat pump t period; p _wSHP(t) be the power consumption of water resource heat pump t period;

C) user's side air-conditioning heat pump constraint

Thermoelectricity is than retraining:

h _EHP(t,l)=COP·p _EHP(t,l) （8）

The air-conditioning heat pump upper limit of exerting oneself:

0≤p _EHP(t,l)≤min(P _EHP(l),H _load(l)/COP) （9）

Wherein, P _eHP(l) be l group user's air-conditioning heat pump capacity sum; H _load(l) be l group user's heating load power; COP distributing air-conditioning heat pump thermoelectricity compares coefficient;

Air-conditioning heat pump power consumption heat supply both can compensate the deficiency of hot water heating, the load of the low-valley interval that also can increase electric power; The heat pump power consumption sum of all user's groups of day part:

$p_{\mathrm{EHPs}}\left(t\right)=\underset{l=0}{\overset{L}{\mathrm{\Σ}}}{p}_{\mathrm{EHP}}(t,l)---\left(10\right)$

P wherein _eHPthe power consumption of l group user heat pump when (t, l) is t;

By the H measuring in step I i _wSHPp with prediction _cHP(t), in step I i, calculate variable P _load(t), H _load(l), P _eHP(l) in substitution formula (1)～(10) and combine and solve, when target function Δ p is minimum value, try to achieve optimize after gained performance variable: the generated output p of fired power generating unit _cHP(t), the heat of the water resource heat pump h that exerts oneself _wSHP(t), user air-conditioning heat pump power consumption p in the same time not _eHP(t, l) and heating load h _eHP(t, l);

Iv. sending control signals to supply and user performs an action

According to gained performance variable after the optimization of iii, variable signal is sent to supply side and user, carry out specifically action, as follows:

According to the generated output p of fired power generating unit _cHP(t), the heat of the water resource heat pump h that exerts oneself _wSHP(t) signal, controls water resource heat pump and fired power generating unit and in future, regulates the action of day part in the time;

According to user heat pump power consumption p in the same time not _eHP(t, l) and heating load h _eHP(t, l), controls user's side different distance user and uses air-conditioning heat pump heating amount, and the amount of closing radiator flowing water valve.
