Embodiment

Below in conjunction with drawings and Examples, the present invention will be further described.

The present embodiment provides a kind of high-end manufacturing enterprise quality power to increase the quantization method of premium value, as shown in Figure 10, comprises the following steps:

Step S1: determine the effectiveness PPU (premiumpowerutility) that quality power brings according to evading psychology based on quality power index PPI (premiumpowerindex) and business risk

Described step S1 specifically comprises the following steps:

Step S11: with the SEMIF47 standard enforced in IT manufacturing for benchmark, the order of severity of falling temporarily of IEEEStd1564-2014 definition is index, as shown in Figure 1, with quality power index x=1 for separation, when voltage dip is more than SEMIF47 standard, x>1, otherwise, x<1.Then the value x of quality power index PPI is as shown in the formula shown in (1):

$x=\frac{1-M}{1-M_{curve}\left(D\right)}---\left(1\right)$

Wherein, M, D are respectively voltage dip amplitude, duration, M _curve(D) be reference voltage amplitude that SEMIF47 curve specifies.Usually, be that benchmark survey surveys voltage dip with SEMIF47, obtain the voltage dip distribution that enterprise stands, with 1 year for the cycle is added up.According to formula (1) and IEEEStd1564-2014 determine enterprise stand the order of severity of falling temporarily, obtain quality power and refer to target value x.

Step S12: build enterprise's perception utility models; According to the voltage sag immunity curve of business equipment, determine enterprise's perception effectiveness.Wherein effectiveness is the degree that certain commodity or labor service meet enterprise's desire or demand, relevant with enterprise perception, is that enterprise carries out being worth and passes judgment on, determines to buy or the foundation of investment.The accounting of grid electricity fee cost in total cost of high-end manufacturing enterprise is very little, but the loss supplying electric disturbance to cause it is huge, and therefore, the need for electricity of this kind of enterprise not only relates to power supply continuity and electricity price, also relates to quality power and power disturbance.In reality, the differences such as the production technology of different enterprise, product property, market share and consumer characteristic, widely different to the real needs of quality power, introduce electricity consumption Concept of Utility, unified need for electricity of portraying this type of enterprise.

Enterprise's perception effectiveness c (x) is by risk averse psychological impact, available anti-S function represents, as shown in Figure 2, when the voltage sag immunity of business equipment meets SEMIF47 standard, enterprise is to quality power index x=[0, the loss that may cause time 1] is more paid close attention to, enterprise's perception effectiveness value is in fig. 2 negative, and under identical temporary range of decrease value, and it is longer to fall the duration temporarily, enterprise's psychological response is stronger, and c (x) declines faster.In Practical Project assessment, SEMIF47 curve can fall immunity curve temporarily with virtual voltage and replace.Consider enterprises' loss evade psychology enterprise's perception effectiveness can portray into:

$c\left(x\right)=\left\{\begin{array}{cc}{\left(1-x\right)}^r& x<1\\ -\mathrm{\&lambda;}{\left(x-1\right)}^r& x>1\end{array}\right.---\left(2\right)$

Wherein, r is risk-aversion coefficient, and value 0<r<1, λ are loss aversion coefficient, value λ >1, and concrete value can investigation statistics or expertise be determined.

Step S13: determine the effectiveness PPU that quality power brings;

The loss that statistics enterprise stands, tries to achieve the contribution rate b of enterprise's perception effectiveness in total utility by regression analysis, in conjunction with the enterprise's perception effectiveness obtained, thus determines the effectiveness that quality power brings, such as formula (3).

PPU＝bc(x)(3)

Wherein, b is the contribution rate of enterprise's perception effectiveness in total utility.

Step S2: the part the surveyed PU (powerutility) determining business electrical effectiveness; Described step S2 specifically comprises the following steps:

Step S21: calculate enterprise net income and expect; Be generally year's purchase and expect ENB (expectednetbenefit)

Enterprise's perception effectiveness is mainly lost, the voltage dip loss C of enterprise k perception _sag(k) be:

C _sag(k)＝N _k·C _k(4)

Wherein, N _kfor cause lose temporarily number of times falls, C _kfor each loss.

Net proceeds expectation value I (k) of enterprise k is:

I(k)＝C(k)-C _sag(k)-C _BI(k)(5)

Wherein, C (k) is total revenue, C _sag(k) for fall loss temporarily, C _bIk () is cost of investment.

Step S22: consider that business risk evades psychology, determine described enterprise k normal electricity consumption effectiveness NPU (normalpowerutility)

Introducing risk averse psychology, expects in conjunction with enterprise net income, determines enterprise k normal electricity consumption effectiveness NPU, such as formula (6).

$NPU\left(k\right)=\frac{I{\left(k\right)}^{1-a}}{1-a}---\left(6\right)$

Wherein, I (k) expects (being generally year's purchase to expect) for enterprise net income, comprises normal investment, loss and income etc.A is the risk averse coefficient that reflection business risk evades psychology.

Step S23: according to prospect theory and accumulation prospect theory, in conjunction with the effectiveness that the quality power obtained brings, determines that business electrical effectiveness can survey part PU (powerutility)

According to utility theory (utilitytheory), the electricity consumption effectiveness of enterprise may be defined as the degree that electric power that enterprise consumes can meet its particular demands, is that enterprise is to be met a kind of Psychological Assessment.Different enterprise is different to the subjective psychology perception of electricity consumption effectiveness, its difference shows as the willingness to pay (willingnesstopay of different enterprise, WTP) and compensation accept wish (willingnesstoaccept, WTA) difference, and psychology is evaded in the loss that in fact different WTP and WTA reflect different enterprise.In addition, enterprise's perception electricity consumption effectiveness is also relevant with the uncertain factor such as market share, product competitiveness of enterprise product, and therefore, business electrical effectiveness is by surveying and can not survey two parts and form:

Wherein, U is total electricity consumption effectiveness to U=PU+ ε (7), and PU is the part surveyed of electricity consumption effectiveness, and ε, for can not survey part, has stochastic uncertainty.The prospect theory (prospecttheory) proposed according to scholar Kahneman and Tversky and accumulation prospect theory (cumulativeprospecttheory), enterprise is not only concerned about normal electricity consumption costs and benefits, more obtainable electricity consumption effectiveness under care power supply quality index.Therefore, the PU in formula (7) can be analyzed to effectiveness two parts that normal effectiveness and quality power bring:

$PU=PU(I,x)=NPU+PPU=\frac{I^{(1-a)}}{1-a}+bc\left(x\right),(0<a<1,b\&GreaterEqual;0)---\left(8\right)$

The electricity consumption effectiveness of high-end manufacturing enterprise k can survey component assesses flow process as shown in Figure 3.

Step S3: determine that quality power increases premium value PPV model according to corporate payments wish WTP (willingnesstopay);

The WTP of enterprise is that enterprise is ready exchange the quality power of specific indexes for the currency arranged of some and obtain the wish expecting electricity consumption effectiveness.Obviously, WTP is the function of electricity consumption effectiveness c (x), as shown in Figure 2, and the function of c (x) to be value the be PPI of x.By law of diminishing marginal utility, when enterprise investment ability and the ability to ward off risks one timing, also meet production decline law to the marginal willingness to pay of quality power, the quality power demand represented with WTP is a curve tilted to the right, as shown in Figure 4.

Visible, when in formula (7), total electricity consumption effectiveness U of enterprise expectations is constant, if by required investments, the immunity improving business equipment or the temporary precipitation reducing supply terminals are put down, when PPI is from x ₀be reduced to x ₁time, AB is the investment that enterprise is ready to pay for this reason.When PPI changes, also wish that total electricity consumption effectiveness U brings up to U ₁, then CD is the investment that enterprise is ready to pay for this reason.As CD >=AB, just there is willingness to pay in enterprise.

When investment INV makes PPI from x ₀become x ₁time, the results form investment of enterprise's energy perception are that U is by U ₀rise to U ₁, only have U ₁>=U ₀time, just there is willingness to pay in enterprise, that is:

PU (I-INV, x ₁)+ε ₁>=PU (I, x ₀)+ε ₀(9) wherein, ε ₀and ε ₁for independent random variable and obey Weibull distribution.

Enterprise investment probability P _yesfor:

$\begin{array}{c}{P}_{yes}=P\&lsqb;PU\left(I-INV,x_1\right)+{\mathrm{\&epsiv;}}_1\&GreaterEqual;PU\left(I,x_0\right)+{\mathrm{\&epsiv;}}_0\&rsqb;\\ =P\&lsqb;{\mathrm{\&epsiv;}}_0-{\mathrm{\&epsiv;}}_1\&le;PU\left(I-INV,x_1\right)-PU\left(I,x_0\right)\&rsqb;\\ =P\&lsqb;\mathrm{\&theta;}\&le;\mathrm{\&Delta;}PU\&rsqb;\end{array}---\left(10\right)$

Wherein, Δ PU=PU (I-INV, x ₁)-PU (I, x ₀) for the variable quantity of electricity consumption effectiveness can be surveyed, θ=θ ₀-θ ₁for stochastic variable, if use F _θrepresent the cumulative distribution of stochastic variable θ, can obtain:

P _yes＝P(θ≤ΔPU)＝F _θ(ΔPU)(11)

According to existing research conclusion, the difference of two Weibull distribution stochastic variables obeys Logistic distribution, and therefore, enterprise is ready that the probability of investing is:

P _yes＝F _θ(ΔPU)＝(1+e ^-ΔPU) ^-1(12)

When investment can improve electricity consumption effectiveness, enterprise is ready that the investment amount paid depends on that investment income increases the size of premium value.Convolution (8), to formula (12) integration, can obtain the increasing premium value of enterprise k:

$PPV\left(k\right)=\underset{o}{\overset{INV{\left(k\right)}_{\max }}{\&Integral;}}{(1+e^{-\mathrm{\&Delta;}PU\left(k\right)})}^{-1}dINV\left(k\right)---\left(13\right)$

Wherein, INV (k) _maxfor the maximum investment amount of enterprise k, depend on installation, O&M cost etc., PPV (k) invests the quality power that can bring to increase premium value.

The present invention is based on utility theory and increase the theories of value that overflows and high-end manufacturing enterprise quality power increasing premium value is quantized, consider that enterprises' loss evades psychology, electricity consumption effectiveness is divided into and can surveys part and can not part be surveyed, reasonably feature the perception effectiveness of high-end manufacturing enterprise to quality power, in conjunction with the willingness to pay of enterprise, quantize high-end manufacturing enterprise quality power and increased premium value.

For 5 enterprises of high-end manufacturing enterprise in certain high and new tech park and garden, at the quality power of different times, premium value is increased to different enterprise and same enterprise and assesses.There is 3,220kV transformer station this garden, 10,110kV transformer station.5 enterprise L ₁~ L ₅all through 110kV access via telephone line utility network, it is that business equipment is powered that the power distribution network be made up of cable through enterprises is depressured to 10kV, and wiring diagram as shown in Figure 5.2007 ~ 2014 years, 5 enterprise 10kV buses survey voltage dip number of times statistics as shown in Figure 6.According to the investigation statistics falling loss for 2007 ~ 2014 years temporarily to these 5 enterprises, by regression analysis must be with the correlation parameter in electricity consumption utility function: a=0.12, b=10, r=0.88, λ=2.25.

1) business electrical effectiveness value analysis excessive in increasing

With L ₅for example, 2007 ~ 2014 years, enterprise's side 10kV bus actual measurement voltage dip, as shown in Figure 7, measure voltage dip altogether 208 times, wherein, what cause enterprises' loss fell 15 times temporarily.
