Description

{System and Method for calculating environmental cost standard value by time period}

The present invention relates to a technology for calculating carbon dioxide emissions, and more specifically, to a system and method for calculating the standard factor for environmental costs by time period, which can calculate the actual carbon dioxide emissions for each power generation facility unit when producing 1 kW of electricity.

In addition, the present invention relates to a system and method for calculating the standard coefficient of environmental costs by time period, which can calculate environmental costs when calculating power generation-linked retail rates.

While electricity rate reform is currently in progress, a fuel cost index system is being introduced and environmental costs are being charged separately from the electricity rate. In general, the fuel cost indexation system is a system that provides a price signal to the electricity market by automatically reflecting price changes in fuels such as coal, natural gas, and heavy oil used in electricity production in electricity rates. The purpose of this fuel cost indexing system is to encourage reasonable electricity consumption for consumers and to alleviate financial risks for electric utility companies. The purpose is to reflect changes in fuel costs every month as fuel cost adjustment cost items.

In addition to this system, not only fuel costs but also environmental costs, such as carbon dioxide emissions from power generation sources, must be reflected in electricity bills. When generating power using coal-fired power generation or liquefied natural gas (LNG), environmental costs are calculated differently depending on the fuel used for power generation and are periodically reflected in retail electricity bills, creating a demand management effect that saves electricity during times when environmental costs are high. and to reduce carbon dioxide associated with power consumption.

In the case of KEPCO, this policy change not only has a very large financial impact, but is also closely related to customers' electricity use and rates, so we provide reliable information through accurate data verification when calculating fuel cost indexation or environmental charges. Should be.

There is no standard coefficient for environmental costs such as carbon dioxide emissions from power generation fuel, so the same value is applied to nuclear power, coal, and LNG. Although the carbon dioxide emission coefficient for each power source used to produce electricity is different depending on the season and time of day, the same emission coefficient, that is, 0.424kgCO ₂ /kWh, is applied to the same usage (production amount), thereby distorting the emissions. To elaborate, the carbon emission factor (unit is kg/kWh) for each power generation source to produce electricity (for example, nuclear power, coal, domestic coal, LNG, oil, wind power, solar power, etc.) and the current use Carbon dioxide emissions are calculated by applying the existing carbon emission coefficient.

As a result, when comparing the carbon emissions of each power generation source and the carbon emissions of electricity consumption, a difference of approximately 11,960,389 CO ₂ /t occurs based on a specific month.

If 25,000 won per ton is applied for carbon emissions rights (when calculating emissions regardless of whether they are free or paid), there is a difference of 300 billion won per month depending on the emission factor. This may be reflected in the electricity bill and passed on to electricity consumers, or the cost of purchasing electricity may increase, so there is a need to establish a standard for the standard coefficient for environmental costs. However, technology to calculate or index standard coefficients for these environmental costs has not yet been developed.

Therefore, the fuel cost index system or the separate imposition of environmental costs have a huge impact on the financial impact of a company, so in calculating environmental costs, a system that calculates accurate costs by time period based on the amount of power generation generated by the power exchange's power operation and the corresponding A system that performs verification is absolutely necessary.

Meanwhile, a method for calculating carbon dioxide emissions is known in some patent documents. However, this method is limited to calculating carbon dioxide emissions based on the amount of electricity used by consumers. Additionally, in order to calculate carbon dioxide emissions for electricity usage, carbon dioxide emissions are simply calculated by multiplying electricity consumption (1kWh) by the carbon emission coefficient of 0.424kgCO2/kWh.

In addition, in order to produce electricity, different power generation resources (fuel) are inputted at different times to produce electricity, and although carbon dioxide (CO ₂ ) emissions are different, if the same amount of electricity is produced at different times, carbon dioxide (CO ₂ ) emissions are different. Since this appears the same, a problem arises where the figures are different from the actual carbon dioxide emissions from power generation facilities and fuel.

Hereinafter, with reference to the attached drawings, a system and method for calculating the standard coefficient of environmental costs by time period according to an embodiment of the present invention will be described in detail.

Figure 1 is a block diagram of a system 100 for calculating standard coefficients of environmental costs by time period according to an embodiment of the present invention. Referring to FIG. 1, a power market analysis unit 110 that generates power market information, a standard coefficient calculation block 120 that calculates the environmental cost standard coefficient and emissions by time period using the power market information, and a standard coefficient calculation block 120 that calculates the standard coefficients and emissions by time period. It may be configured to include an output unit 160 that outputs, a carbon emission management unit 170 that manages standard coefficients and emissions.

The power market analysis unit 110 performs the function of generating power market information. To this end, the power market analysis unit 110 is linked to the power market total analysis system (MTAS) and the real-time power information provision system (i_SMART). The power market total analysis system (MTAS) can verify power market operation performance such as power generation plan and market price (SMP: System Marginal Cost) in the short term, and in the mid to long term, power purchase costs and profits by power generation company. It is an analysis system that can predict the effect of demand management. For this purpose, market simulation at the power exchange level is possible. Therefore, operation development plan result data can be generated according to the operation development scenario. Of course, the operation development plan result data can also be generated through user input information.

The real-time power information provision system (i_SMART) performs the function of providing real-time information usage, forecast information, and real-time monitoring of demand management in approximately 15-minute increments based on remote meter reading data. In other words, power production information for each time period is generated.

The standard coefficient calculation block 120 performs the function of calculating the standard coefficient of environmental costs and emissions for each time period using electricity market information. To this end, the standard coefficient calculation block 120 may be configured to include an analysis and classification sub-block 130, a calculation sub-block 140, and a disclosure unit 150.

The analysis and classification sub-block 130 includes an electricity production analysis unit 131 that classifies the electricity production by power generation resource by time zone and power generation resource according to the operation power generation plan result data, and a group classification unit 132 that groups the classified power generation resources. It consists of

The electricity production analysis unit 131 classifies the electricity production by power generation resource for approximately 240 households every hour (24 hours) according to the operation and development plan of the power exchange by time zone and power generation resource. In addition, it provides standard data for classification into groups by time zone and power generation resource. Here, the amount of electricity production by power generation resource is generated by collecting operational power generation plan result data from the power market analysis unit 110 (in particular, the power market comprehensive analysis system (MATS)). The operational power generation plan result data includes input generator information and electricity by time period. Includes production information, etc.

The group classification unit 132 classifies the power generation resources used for electricity production based on data managed by the electricity production analysis unit 131 over a 24-hour period, such as nuclear power, coal, domestic coal, LNG, petroleum, hydropower, pumped water, wind power, etc. Grouped into solar power, tidal power, and other (other renewable energy). Here, the standard group is the basic fuel unit for calculating carbon dioxide emissions for each power generation resource used for electricity production. In other words, it is based on the power generation source of the Korea Power Exchange.

The calculation sub-block 140 performs the function of calculating the standard coefficient of environmental cost and carbon dioxide emissions for each time period. To this end, the calculation sub-block 140 may be configured to include a market share calculation unit 141, a production volume calculation unit 142, and an emission coefficient and emission calculation unit 143.

The occupancy calculation unit 141 calculates the production share (occupancy_rate) for each power generation resource with respect to the total power generation production on a group basis. This can be expressed mathematically as follows:

Here, G is the power generation capacity, h = n|1 ≤ n ≤ 24, t is the power generation resource group, n is the number of power generation resource types, and T is the total power generation time.

Therefore, in the above equation, G _h T means the power generation amount for the power generation resource group (t) in a specific time zone (h), and the share is calculated by dividing it by the total power generation amount for each power generation resource in each time zone.

Continuing to refer to FIG. 1, the production calculation unit 142 classifies each power generation resource and calculates the usage amount by using the production share of each power generation resource based on the production amount by time zone in the operation power generation plan result data. For example, if the usage at a certain time is 1 million kWh, the production share by power generation resource is nuclear power 23.9%, coal 30.6%, domestic coal 1.4%, LNG 24.0%, oil 7.2%, hydropower 2.1%, pumped water 5.0%, and other 5.7%. It can be %.

That is, production by power generation resource in a specific time zone = usage amount in a specific time zone Calculate carbon dioxide emissions by time zone by adding the value multiplied by the carbon dioxide coefficient. When calculating carbon dioxide emissions by time based on power consumption, the transmission and substation loss rate and on-site loss rate are calculated. In addition, a function can be performed to compare the power production with the value multiplied by 0.424kgCO ₂ /kWh.

In addition, the emission coefficient and emission calculation unit 143 calculates carbon dioxide emissions by power generation resource for the total monthly electricity consumption even when there is no hourly meter reading data or only monthly electricity usage (customers without remote meter reading). To obtain the standard share of power generation resources by time/day/month. Using this standard occupancy rate for each power generation resource, the standard production rate for each time period is calculated. Based on the above results, obtain the standard emission coefficient and emissions by time zone/day/month. By applying the transmission loss rate and power generation in-house loss rate here, the standard carbon dioxide emission factor and emissions according to electricity production and electricity consumption can be calculated and applied to related work.

The standard occupancy rate by time zone/daily/month by power generation resource is applied by calculating the average occupancy rate by power generation resource for the previous 4 weeks for each time zone and day of the week in the case of weekdays. The same goes for holidays.

The standard production share (SR) for each power generation resource can be defined as follows.

Here, R : daily share, t = power generation resource group, h : time, d : date, n : number of days.

The results of calculating the production volume by power generation resource by reflecting the standard production share of each power generation resource can accurately apply the carbon emission coefficient for each raw material and energy production to calculate the actual carbon emissions by time zone, and the carbon emissions by power generation resource by time zone. Trends can be analyzed. As shown in the formula below, carbon emissions by time zone can be calculated as the sum of carbon emissions by power generation resources in each time zone.

The result of calculating the electricity production by power generation resource by reflecting the standard production share of each power generation resource (U _h (t)) can calculate the actual carbon emissions by time period by accurately applying the carbon emission coefficient for each raw material and energy production. . Therefore, it is possible to analyze carbon emission trends by power generation resource over time. As shown in the formula below, carbon dioxide emissions (C _h ) by time zone can be calculated as the sum of carbon emissions by power generation resources in each time zone.

Here, h : time, t : power generation resource group, k(t) : carbon dioxide emission coefficient by power generation resource, U _h (T): electricity production by power generation resource. The carbon dioxide emission coefficient is a secondary coefficient for the oil conversion coefficient based on the calorific value ratio of each power generation resource to 1 kg of crude oil.

Therefore, the standard environmental cost coefficient is calculated by applying the social cost of carbon (SCC) to carbon dioxide emissions (C _h ) for each time period.

To elaborate, the social cost of carbon (SCC) is a quantitative measure developed to quantify climate change and refers to the net economic cost of carbon dioxide emissions, and is the currency of damage per unit atmospheric emissions (ton) of carbon dioxide. This is a rough estimate. The U.S. Environmental Protection Agency (EPA) has been calculating and using SCC estimates to analyze the impact of carbon dioxide since 2008. This can be expressed in a table as follows.

Therefore, the environmental cost standard coefficient is calculated by applying various environmental values to carbon dioxide emissions (Ch) by time period. In other words, the environmental cost standard coefficient = carbon dioxide emissions by time period (Ch) × cost factor coefficient. Here, the cost factor coefficient is a value calculated by applying various environmental values, as described above.

Continuing to refer to FIG. 1, the disclosure unit 150 provides the standard production share of carbon dioxide by time zone/day/month, carbon dioxide emission coefficient by time zone/day/month, and carbon dioxide emission information by time zone/day/month by businesses, buildings, and power consumers. It is provided through a web service to support the calculation of carbon dioxide emissions by power generation resource by time zone. In addition, businesses, buildings, and power consumer terminals provide customer authentication and the ability to store data in XML (Extensible Markup Language) to use this information.

The output unit 160 performs the function of displaying information processed by the analysis and classification block 130, the calculation block 140, and the disclosure unit 150. Accordingly, the output unit 160 can output information in a combination of text, voice, and graphics. To this end, the output unit 160 may be configured to include a display, a sound system, etc.

The display may be a Liquid Crystal Display (LCD), Light Emitting Diode (LED) display, Plasma Display Panel (PDP), Organic LED (OLED) display, touch screen, Cathode Ray Tube (CRT), or flexible display. In the case of a touch screen, it can function as an input means. Of course, in FIG. 2, the output unit 240 is shown as being included in the processing unit 140, but this is for understanding purposes and the output unit 250 is configured separately from the processing unit 140.

The electricity production analysis unit 131 shown in FIG. 1, group classification unit 132, market share calculation unit 141, production calculation unit 142, emission coefficient and emission calculation unit 143, disclosure unit 150, etc. means a unit that processes at least one function or operation, and may be implemented in software and/or hardware. In hardware implementation, an application specific integrated circuit (ASIC), digital signal processing (DSP), programmable logic device (PLD), field programmable gate array (FPGA), processor, microprocessor, and other devices designed to perform the above-described functions. It may be implemented as an electronic unit or a combination thereof.

Software, data, etc. can be stored in memory and executed by a processor. The memory or processor may employ various means well known to those skilled in the art.

Continuing to refer to FIG. 1, the carbon emission management unit 170 receives information from the disclosure unit 150 and performs the function of managing carbon emission rights. Accordingly, the carbon emission management unit 170 may be configured as a separate server and may be connected through a communication network (not shown). A communication network refers to a connection structure that allows information exchange between nodes such as multiple terminals and servers, such as public switched telephone network (PSTN), public switched data network (PSDN), and integrated services digital network (ISDN). Networks), Broadband ISDN (BISDN), Local Area Network (LAN), Metropolitan Area Network (MAN), Wide LAN (WLAN), etc. However, , the present invention is not limited thereto, and includes wireless communication networks such as CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), Wibro (Wireless Broadband), WiFi (Wireless Fidelity), and HSDPA (High Speed Downlink Packet Access). Network, Bluetooth, NFC (Near Field Communication) network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. Alternatively, it may be a combination of these wired communication networks and wireless communication networks.

Of course, this communication network can also be applied to the communication connection between the power market analysis unit 110 and the standard coefficient calculation block 120. The power market analysis unit 110 may be configured as a separate server.

Figure 2 is a flowchart showing the standard grouping process for each time zone and power generation resource according to an embodiment of the present invention. Referring to FIG. 2, when the operation power generation plan result data is first collected, the standard coefficient calculation block 120 separates a plurality of generators by time zone and by power generation resource by time zone (steps S210, S220, and S230). In Figure 2, the generator number 240 is illustrated, but the number is not limited to this number. Therefore, it may be a smaller number or a larger number.

Afterwards, the standard counting block 120 checks whether the power generation resources are grouped into one group (step S240).

As a result of confirmation, if it is not grouped into one group in step S240, a group is added (step S241). Afterwards, steps S220 to S240 proceed.

In contrast, if the power generation resources belong to one group in step S240, a group for each power generation resource for each time zone is created (step S250). Afterwards, time zones are grouped by power generation resources, and electricity production is grouped (steps S251 and S260).

FIG. 3 is an example of standard grouping for each time zone and power generation resource shown in FIG. 2. Referring to FIG. 3, a grouping list 340 is created by combining the generator list 310 and the standard group 320 for each generation resource by time zone through a multiplier 330.

The grouping of power generation resources by time zone is as follows.
