Embodiment one
Referring to Figure 1, Fig. 1 is a kind of process of the handling of scrapped goods and materials method in comprehensive energy market provided by the embodiments of the present application
Figure comprising following steps, it should be noted that the executing subject of following steps is comprehensive energy service provider:
S101: the goods and materials output quantity of itself next day is calculated；
Wherein, the goods and materials of itself output are divided into controllable quantity goods and materials and the uncontrollable goods and materials of quantity, the uncontrollable goods and materials of quantity
Goods and materials output quantity is that uncontrollable factor is calculated in a manner of stochastic variable.
Energy services quotient can voluntarily output some electrical power according to owned generating equipment, it is assumed that wherein includes firepower
Generating set and photovoltaic power generation unit, then wherein the secondary daily generation of thermal power generation unit be exactly controllable quantity goods and materials (substantially not
Influenced by the external world), the secondary daily generation of photovoltaic power generation unit is exactly the uncontrollable goods and materials of quantity.This is because photovoltaic power generation and next day
Weather, intensity of illumination, there are biggish relationships between the various uncontrollable factors such as whether have unexpected shelter.
Further, as these above-mentioned uncontrollable factors can not be predicted in advance substantially, but have some or can be one
Determine to know in advance in degree, such as weather, can be used directly and predict for the parameter for some effects factor that anticipated that
It is worth, or corrects the stochastic variable of bad student using the value predicted, so that be calculated based on revised stochastic variable
It is closer with the actual output quantity on the day of next day.
S102: the material requirements quantity of user's next day is calculated；
Wherein, material requirements quantity is uncontrollable, and material requirements quantity is by uncontrollable factor with the side of stochastic variable
What formula was calculated.
It is assumed that energy services quotient for its user provides electric power and natural gas two kinds of energy simultaneously, then due to people this vulnerable to
The presence for the factor that various aspects influence, so that next day electric power and Natural Gas Demand can not also be predicted.The factor being directed to is excessive,
Such as some marketing policys of local or associated mechanisms publication, promotion sell, temporarily from etc., can all make the goods and materials of user's next day
Quantity required is unpredictable.In this example, the demand of demand and natural gas quantity of user's next day to amount of energy all belongs to
In uncontrollable factor, therefore the application is also that it is participated in the calculating process into material requirements quantity in a manner of stochastic variable.
It should be noted that the mode or algorithm of generating random variable have very much, it is contemplated that the absolute of numerical value may be used also at random
It can bring worse compared to the prior art as a result, therefore it is also an option that the stochastic variable choosing of suitable the application application scenarios
Mode is taken, by test of many times, one of proper mode is the stochastic variable of selection Normal Distribution, that is to say,
Stochastic variable is Normal Distribution.
The curve of normal distribution is in bell: both ends are low, and intermediate high, symmetrically because its curve is bell-like, therefore people are again
It is often referred to as bell curve.Normal distribution is one to be obtained based on statistics and Probability to precompensation parameter value range very
Good mode, why further limiting the stochastic variable of selection herein is Normal Distribution, also in that above-mentioned more
In kind of uncontrollable factor, occur mutually than before or the probability of history same period value be related to increasing for factor quantity and gradually under
Drop, therefore more appropriate value can be calculated based on Probability, and in this, as stochastic variable.
Further, it in order to enable the value size for the stochastic variable chosen is more suitable, can also be obtained from multiple channel
The various events or message impacted to uncontrollable factor are taken, and are abstracted as weight or correction factor comes to stochastic variable
Value size be modified, the actual value on the day of making finally obtained stochastic variable and next day is more nearly.
S103: adopting in ahead market goods and materials is calculated according to the material requirements quantity of next day and goods and materials output quantity
Purchase quantity；
On the basis of S101 and S102, this step is intended to material requirements quantity and goods and materials output quantity according to next day
The purchase quantity that service provider needs the goods and materials in ahead market is calculated in difference.Certainly, the mode of fortuitous event in order to prevent is led to
It can also often increase that some redundancies are spare on the basis of the difference being calculated, using final quantity as purchase quantity.
S104: according to the difference between the goods and materials actual demand quantity on the day of next day and material requirements quantity, in spot market
It purchases the part goods and materials lacked and sells extra part goods and materials.
On the basis of S103, this step is intended to be obtained by comparing according to the goods and materials actual demand quantity on the day of next day
Difference between the material requirements quantity being calculated with S102, this part variation can not be resolved by ahead market, therefore
It is only solved by spot market, including purchasing the part goods and materials lacked and selling extra part goods and materials.
Based on the above-mentioned technical proposal as can be seen that compared with the prior art, the application by the value of uncontrollable factor with
The mode of machine variable obtains so that the goods and materials output quantity and material requirements quantity that are calculated more be close to it is unpredictable
Actual quantity.Although the variation of the value of these uncontrollable factors there are in fact certain rule, due to excessively complicated
Actual conditions cause the rule excessively obscure, be difficult to be embodied.It is carried out on the basis of long-time historical data multi-party
The conclusion in face can may just obtain the value in the case where variation tendency is constant, but variation tendency can't be unalterable.?
