Description

  TECHNICAL FIELD The present invention relates to a power supply / demand plan creation device and a supply / demand plan creation method, and more particularly, to create an environment-friendly fuel and power generation amount according to the prediction of fuel and power generation amount of a plurality of power generation companies. The present invention relates to a system supply and demand plan creation device and a supply and demand plan creation method.

  The power supply and demand plan is formulated so as to operate the generator economically while balancing the amount of power supplied and the amount of power consumed at the same time.

Typical examples of supply and demand planning system 1, the prior art, receives the supply planning information 31 through the information transmission device 2 from a plurality of power producers _{3 -1,} 3 -2 _··· 3 _-n as shown in Figure 6 Then, the general information creating means 13 creates the general information 32 by adjusting the power generation amount of the power generation companies _3-1 , _3-2, ..., 3- _n so that the supply and demand is not insufficient. transmission equipment power producer ₃ -1 through _2, 3 -2 ... ₃ sends to _-n, power producer _{3 -1,} 3 -2, ... _{3 -n,} based on the transmission result There is one in which each generator is operated (for example, see Patent Document 1).

  The supply and demand plan creation device 1 described in Patent Document 1 is not designed to calculate the amount of generated power in consideration of the environment, but the supply and demand plan in which the amount of generated power is calculated in consideration of the environment. A system to support the power generation business is also under consideration. In other words, the company's total required power supply during the supply / demand planning period, the fuel type of each generator, the unit price of fuel, the amount of power generated by time, and the generator work stoppage (hereinafter collectively referred to as “supply and demand plan information”) ), The power supply system is designed so that the “fuel unit price” x “power generation amount” is the smallest and the “gas emission amount” is within the pollution control factor gas regulation value. .

  FIG. 7 is an overall configuration diagram of a power generation system that performs this kind of environment-conscious supply and demand plan, and conceptually shows the contents of Patent Document 2. FIG.

  The power generation system of FIG. 7 considers the use of environmentally friendly clean fuel (alternative fuel). A fuel service provider 93 is interposed between the fuel supply provider 91 and the power generation provider 92, and this fuel is supplied. The business of the service provider 93 supports the power generation company 92 to promote the conversion from fossil fuel to alternative fuel, and the fuel supplier 91 is configured to promote the stable supply of alternative fuel. Information exchange between business operators is performed via a network.

  Here, the fuel supply company 91 is a company that sells fuel necessary for power generation, and the power generation company 92 is a company that generates power using fossil fuel and alternative fuel as fuel, and sells the power. The fuel service provider 93 receives the operating conditions and current operation data of the power generation facility from the power generator 92 (i), receives fuel price information from the fuel supplier 91 (ii), and these data. Based on the information, the power generation facility of the power generation company 92 obtains a mixture ratio of the fossil fuel and the alternative fuel, which has a lower fuel cost than the case where only the fossil fuel is used (A).

  Next, the fuel service company 93 creates an operation plan for operating the power generation facility at this mixture ratio (B), transfers this operation plan to the power generation company 92 (iii), and is necessary for the created operation plan. Order an alternative fuel to the fuel supplier 91 (iv).

  In response, the fuel supplier 91 delivers the ordered alternative fuel to the power generator 92 (v). The power generation company 92 pays the fuel for the supplied alternative fuel to the fuel supply company 91 (vi).

  In addition, the fuel service operator 93 has a fixed cost that can be reduced compared with the case where the power generation operator 92 operates based on the operation plan delivered in (iii) described above, and operates only with fossil fuel. Is charged to the power generation company 92 (vii), and the power generation company 92 pays the fuel service company 93 (viii).

Similarly, since the fuel service provider 93 orders the necessary alternative fuel from the fuel supply provider 91 in the above (iv), the fuel supply provider 91 charges a brokerage fee that is a certain percentage of the order amount to the fuel supply provider 91 ( ix) The fuel supplier 91 pays a brokerage fee to the fuel service operator 93 (x).
As a result, power generation in consideration of cost and environment is performed within a single power generation company.
