5) electricity charge parameter S is calculated

Under tou power price environment, electricity cost S of resident is expressed as:

S=P_a·T_a·Q_a+P_b·T_b·Q_b+…+P_i·T_i·Q_i+…+P_l·T_l·Q_l (2)

Wherein P_iFor the power of electrical equipment i, T_iDuration, Q is used for electrical equipment i_iElectricity for tou power price corresponding in electric appliance usage time territory Valency level, Q herein_iTo be given according to different Spot Price schemes；

6) comfort quantity D is calculated

Utilize user make the consumption habit of electrical appliance to calculate the comfort level of power program, if in certain power program, each electrical equipment Opening time be respectively a_t,b_t,…,i_t,…,l_t, the opening time of the most each electrical equipment and user first, second and third consumption habit Distance be expressed as:

d₁=| a_t-a₁|+|b_t-b₁|+…+|l_t-l₁|

d₂=| a_t-a₂|+|b_t-b₂|+…+|l_t-l₂| (3)

d₃=| a_t-a₃|+|b_t-b₃|+…+|l_t-l₃|

A in formula₁,a₂,a₃,b₁,b₂,b₃,…,l₁,l₂,l₃It is respectively user first, second and third consumption habit that each electrical equipment is corresponding, by In opening time of power program electrical equipment the closer to the consumption habit of user, then the comfort level of power program is the highest, and electrical equipment is opened Time, then the comfort level of user can be weaker, therefore d the closer to second and the 3rd consumption habit₁,d₂,d₃Shadow to comfort level D It is different for ringing proportion, and the electricity consumption comfort level following formula of user calculates:

D=B₁·d₁+B₂·d₂+B₃·d₃ (4)

In formula: B₁,B₂,B₃Represent d respectively₁,d₂,d₃Weight, set B here₁=0.6, B₂=0.25, B₃=0.15, it is seen then that Comfort level D is the biggest, represents that the electric operation time of this power program does not more meet the consumption habit of user；

7) object function r is built

Take into full account consumption habit and the economic conditions of user self of user, and combine the mesh of Spot Price structure power program Scalar functions, due to electricity consumption comfort level D and electricity cost S unit disunity, it is therefore desirable to two parameters are carried out dimensionless process, Such as following formula:

$\stackrel{\&OverBar;}{D}=\frac{D-D_{\min }}{D_{max}-D_{min}},\stackrel{\&OverBar;}{S}=\frac{S-S_{min}}{S_{max}-S_{min}}---\left(5\right)$

In formula: D_maxThe maximum that in=scheme, electrical appliance number × 24h, i.e. D can get；D_minThe minima can got for D； S_maxFor in corresponding scheme, electrical equipment opens the electricity cost of 24 hours, S_minOpen in the minimum electricity price stage for electrical equipment each in scheme The minima that during operation, S can reach；WithFor nondimensional electricity consumption comfort level and electricity cost；
