Description

[Background Art] [0002] The risk hedging system of a fuel cell power generation business due to a rise in gas price is a system for hedging a risk of a fuel cell,

The risk hedge system of the fuel cell power generation business due to the rise in gas prices will be launched. More specifically, a risk hedge system for a fuel cell power generation business is disclosed in which a risk of a fuel cell power generation business due to an abnormal increase in gas price can be hedged and the fuel cell power generation business can be activated.

Renewable energy is energy that transforms existing fossil fuels or transforms renewable energy including sunlight, water, geothermal, precipitation, and biological organisms. These renewable energy sources include fuel cells, solar power, wind power, bio, waste and water power.

In order to promote the development and utilization of new and renewable energy, the renewable energy portfolio standard (RPS) system, which was enacted in January 2012, requires renewable energy portfolio standard It is a system that makes it mandatory to secure the amount of renewable energy generation. Since the early 2000s, the system has been introduced and operating globally in the UK, Sweden, Canada, Japan, Australia and the United States to reduce carbon dioxide emissions and grow the renewable energy market.

As a result of the addition of the REC trading system to the RPS system, there has been a market in which buyers and sellers of renewable energy can buy and sell renewable energy through REC. Since the RPS is mandatory, fines may be imposed or other sanctions may be imposed in accordance with the enforcement ordinance if the quota is not secured through production and / or purchase.

The mandatory supply of new and renewable energy starts from 2% in 2012 and is specified in the Enforcement Decree to increase to 10% after 2023.

The introduction of the RPS system has the following effects: First, it is possible to expand the supply of new and renewable energy by mandating the generation of new and renewable energy directly to the generation company. Second, there is no need for government finances to be implemented because the cost of implementation is conserved through the electricity market. Third, the cost of generating new and renewable energy is determined in the market, so competition and reasonable pricing are possible.

However, unlike solar power, wind power, and hydro power, the fuel price of renewable energy is unusually high when the price of raw material gas rises abnormally. Therefore, the fuel cost of the fuel cell and fuel cell power generation company There is a problem in that the REC transaction is not activated due to excessive and unpredictable risks of RPS observers who want to purchase RECs and financial institutions that want to do project financing (PF) transactions to fuel cell power generation companies.

The generation server generates 5-2 information based on the 5-1 information, stores the 5-2 information, and transmits the 5-2 information to the TREC approval determination unit in response to an external request (S26).

The TREC approval determination unit may determine whether the provisional renewable energy supply certificate (TREC n ) price (i.e., the 5-1 information) has been approved by the server of the generation company based on at least the 5-2 information And transmits the 5-1 information and / or the price information of the 5-2 information to the TREC changing unit or the FREC managing unit according to the determination result, and activates the TREC changing unit or the FREC managing unit. Specifically, the TREC approval determination unit determines whether the 5-2 information includes an approval signal or an disapproval signal, and when the 5-2 information includes a signal that is not approved, the TREC approval determination unit determines whether the 5-2 information And transmits the unit price information to the TREC changing unit to operate the TREC changing unit. When the fifth-to-second information includes an acknowledgment signal, the unit price information of the 5-1 information or the 5-2 information is transmitted to the FREC managing unit And activates the FREC management unit.

If the TREC change determining unit determines that the provisional renewable energy supply certificate (TREC n ) price (i.e., the 5-1 information) is disallowed by the TREC approval determination unit, Information to the TREC management unit, restarts the TREC management unit, and causes the TREC management unit to change the 5-1 information based on at least the 5-2 information of the 5-2 information (S27). At this time, the TREC changing unit may change the 5-1 information by further considering at least one of the fourth information and the internal information, as well as the 5-2 information, among the 5-2 information. If the 5-1 information is changed, the 5-2 information may not be changed or changed.

If the FREC management unit determines that the provisional renewable energy supply certificate (TREC n ) price (i.e., the 5-1 information) has been approved by the TREC approval approval determiner, the final renewable energy supply certificate (FREC n) storing this by generating a sixth information related to the price, and sends out the sixth information in response to an external request portion AC determined (S28). The unit price information of the sixth information is the same as the unit price information of the 5-1 information and the 5-2 information which are not changed or changed.

The AC determination unit receives the third information, the fourth information, and the sixth information from the FSP management unit, the SMP management unit, and the FREC management unit in FIG. 3 (S29, S30, and S28) Determines the seventh information related to the compensation amount (AC n ) differentially assigned to each step of the fuel cell power generation period, stores the seventh information, and transmits the seventh information in response to an external request (S31).

5 is a graph for explaining the operation and effect of the risk hedging system 100 of the fuel cell power generation business according to an embodiment of the present invention.

Referring to FIG. 5, the price of the fuel cell gas increases gradually as the power generation period elapses (see the trend line).

If the gas price rises abnormally such as R 1 and R 2 during the power generation period, the systematic marginal price (SMP n ) and the renewable energy supply certificate (REC n ) price will abnormally skyrocket. In this case, the final selling price (FSP n ) also surges abnormally according to Equation (1).

Conventionally, when a power generation company purchases a renewable energy supply certificate (REC n ) from a fuel cell power generation company, the power generation company assumes an unlimited liability due to a surge in the gas price, renewable energy supply certificates (REC n) to pay the purchase price or, on the contrary, despite the fuel cell power generation operators of the gas price increase to bear unlimited liability in accordance with the surge of gas prices and limited renewable energy supply certificates (REC n) Only the method of receiving the payout was discussed. Therefore, in the past, none of the power generation companies, the fuel cell power generation companies, and the financial institutions intending to deal with the project financing (PF) transactions with the fuel cell power generation companies are willing to bear unlimited responsibility for the rise in gas prices. There is a problem that it is difficult to be done.

In order to solve the above problems, a risk hedge system 100 for a fuel cell power generation business according to an embodiment of the present invention has been developed.

For example, if the 20-year fuel cell power generation period is divided into four stages as shown in FIG. 6, namely, the first stage is 6 years, the second stage is 4 years, the third stage is 5 years and the fourth stage is 5 years, (SMP n ) and final renewable energy supply certificate (FREC n ) prices will increase as the price of gas increases. Therefore, as each stage progresses, the average unit cost of sales of the fuel cell power plant (SMP n + 2 × final FRP n ) is also increased. In this case, the risk hedge system 100 derives the provisional sales unit price by subtracting the step-by-step differential compensation amount from the average step-by-step unit price, and consults with the power generation company and the financial institution to calculate the final sales unit price (FSP 1 , FSP 2 , FSP 3 And FSP 4 ). In the first step higher than the step-by-step the final selling price (FSP 1), a step-by-step by Price (BP 1), after step 2, the step-by-step the final selling price (FSP 2, FSP 3, FSP 4) , a step-by-step by Price (BP 2, BP 3 , and BP 4 ), as well as the difference from the standard prices (BP 2 , BP 3 , and BP 4 ) at each step as the power generation period elapses, and the weighted average sales unit (WASP) will be lowered. The step-by-step reference price means an average price of the gas price during each stage of the development period. However, the present invention is not limited thereto, and in FIG. 5, FSP1, FSP2, FSP3, and FSP4 may be located on the same horizontal line (i.e., a straight line with a slope of 0).

An example of Fig. 5 is shown in Table 1 below.

The first stage (n = 1) The second stage (n = 2) The third stage (n = 3) Fourth step (n = 4) The base price (BP n ) 288 315 341 375 System Marginal Price (SMP n ) + 2 x Final Renewable Energy Supply Certificate (FREC n ) 315 333 356 375 The amount of compensation (AC n ) 0 40 74 112 Final selling price (FSP n ) 315 293 282 263 Weighted Average Unit Price (WASP) 290

Referring to FIG. 5 and Table 1, both the fuel cell power generation company and the generation company bear the limited liability even if the gas price surges during the power generation period abnormally. Accordingly, financial institutions can also make project financing (PF) transactions with the fuel cell power generation company without any burden. Specifically, the fuel cell power generation company can recover the renewable energy supply certificate (REC n ) and the electricity sales price stably during the development period, and can easily finance the project financing (PF) from the financial institution, It is possible to temporarily stop the fuel cell power generation and avoid the risk during the period in which the price surpasses the abnormal rise and surges. Also, a developer who purchases a renewable energy supply certificate (REC n ) from the fuel cell power generation company can purchase a renewable energy supply certificate (REC n ) at a limited price without any risk throughout the entire development period. In addition, since the financial institution can stably recover the sales price of the renewable energy supply certificate (REC n ) from the power generation company and the power sales price from the power exchange during the generation of the fuel cell, the fuel cell power generation company Project financing (PF) transactions. As a result, the fuel cell power generation business can be activated.

While the present invention has been described with reference to the drawings, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
