Description

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

The present invention relates to a technology for calculating carbon dioxide emission, and more particularly, to a system and method for calculating a standard coefficient of environmental cost for each time period, which can calculate the actual carbon dioxide emission for each power generation facility unit when generating 1 kW of electricity.

In addition, the present invention relates to a system and method for calculating standard environmental cost coefficients for each time period capable of calculating environmental costs when calculating power generation-linked retail rates.

While electricity rate reform is currently underway, a fuel cost index system is being introduced and environmental costs are being charged separately from electricity rates. In general, the fuel cost indexation system is a system that provides a price signal to the electricity market by automatically reflecting price fluctuations of fuels such as coal, natural gas, and heavy oil used for electricity production in the electricity price. The fuel cost indexing system aims to induce reasonable electricity consumption for consumers and alleviate financial risks for electric operators. This is to reflect the change in fuel cost every month as a fuel cost adjustment cost item.

In addition to these systems, not only fuel costs, but also environmental costs such as carbon dioxide emissions from power generation sources should be reflected in the electricity rate. When the environmental cost is generated by coal-fired power generation or liquefied natural gas (LNG), it is calculated differently depending on the fuel generated and periodically reflected in the retail electricity rate to save electricity during times of high environmental cost. and to reduce the carbon dioxide associated with electricity consumption.

In the case of KEPCO, such policy changes not only play a very large part in the financial impact, but are also closely related to customers' electricity usage and rates, so we provide reliable information through accurate data verification in calculating fuel cost indexation and environmental charges. Should be.

Since there is no standard factor for environmental costs such as carbon dioxide emission from power generation fuel, the same values for nuclear power/coal/LNG are applied. Although the carbon dioxide emission factor for each power generation source used to generate electricity is different for each season and time period, the emission is distorted by applying the same emission factor, that is, 0.424 kgCO ₂ /kWh, to the same amount of consumption (production). In other words, the carbon emission factor (unit is kg/kWh) and currently used Carbon dioxide emissions are calculated by applying the existing carbon emission factors.

As a result, a difference of about 11,960,389 CO ₂ /t occurs based on a specific month when comparing carbon emissions by power generation and power consumption carbon emissions.

If 25,000 won per ton is applied to carbon credits (when calculating emissions without distinction between free and paid), a difference of 300 billion won per month occurs depending on the emission factor. This may be reflected in electricity rates and passed on to electricity consumers, or electricity purchase costs may increase. Therefore, it is necessary to establish a standard for environmental cost standard factors. However, the technology that can calculate or index the standard coefficient for these environmental costs has not yet been developed.

Therefore, the fuel cost indexing system or the separate environmental cost imposition has a huge impact on the financial impact of a company. A system that performs verification is absolutely necessary.

Meanwhile, a method of calculating carbon dioxide emission is known in some patent documents. However, in the case of this method, it has a limited feature in estimating the carbon dioxide emission according to the amount of electricity used by the consumer. In addition, in order to calculate the carbon dioxide emission for the electricity consumption, only the electricity consumption (1kWh) is multiplied by the carbon emission factor of 0.424kgCO2/kWh to calculate the carbon dioxide emission.

In addition, in order to produce electricity, different power generation resources (fuel) are input for each time period to produce electricity, so carbon dioxide ( _{CO 2 )} emissions are Since this is the same, there is a problem that a number different from the actual carbon dioxide emission by power generation facilities and fuel occurs.

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

1 is a block diagram of a system 100 for calculating a standard coefficient of environmental cost for each 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 a standard factor and emission amount for environmental costs for each time period using power market information, a standard factor and an amount of emission It may be configured to include an output unit 160 that outputs, and a carbon credit management unit 170 that manages standard coefficients and emissions.

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

The real-time power information providing system (i_SMART) performs a function of providing real-time information usage, forecast information, and demand management real-time monitoring in 15-minute units based on remote meter reading data. That is, power production information for each time period is generated.

The standard coefficient calculation block 120 performs a function of calculating the standard coefficient of environmental cost and the amount of emission for each time period by using the electric power market information. To this end, the standard coefficient calculation block 120 may be configured to include the analysis classification sub-block 130 , the calculation sub-block 140 , the disclosure unit 150 , and the like.

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

The electricity production analysis unit 131 classifies the electricity production for each generation resource, which amounts to about 240 units every hour (24 hours), by time period and by generation resource according to the operation and development plan of the power exchange. In addition, it provides reference data for classifying into groups for each time zone and each generation resource. Here, the amount of electricity produced by each generation resource is generated by collecting the operational generation plan result data from the electric power market analysis unit 110 (in particular, the comprehensive electric power market analysis system (MATS). production information, etc.

The group classification unit 132 includes nuclear power, coal, domestic coal, LNG, petroleum, hydropower, pumped water, wind power, Group by solar power, tidal power, and other (other renewable energy). Here, the standard group is a basic fuel unit for calculating the amount of carbon dioxide emission for each power generation resource input for electricity generation. That is, it is based on the power source of the Power Exchange.

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

The occupancy calculation unit 141 calculates an occupancy_rate of production by power generation resources with respect to the total power generation output on a group basis. This can be expressed as a mathematical formula as follows.

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

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

Continuing to refer to FIG. 1 , the production output calculating unit 142 classifies for each power generation resource and calculates the amount of use by utilizing the share of production for each power generation resource based on the production time by time in the operation and power generation plan result data. For example, if the usage for a specific time period is 1 million kWh, the share of production by power generation resource is nuclear 23.9%, coal 30.6%, domestic coal 1.4%, LNG 24.0%, oil 7.2%, hydraulic power 2.1%, pumping water 5.0%, other 5.7 % can be

That is, the amount of production for each generation resource in a specific time period = usage in a specific time period X the production share emission coefficient and the amount of output per generation resource by each generation resource. By adding the value multiplied by the carbon dioxide coefficient, the amount of carbon dioxide emissions for each time period is calculated. When calculating carbon dioxide emissions by time period based on electricity consumption, the transmission and transformation loss rate and on-site loss rate are applied. In addition, it can also perform a function of comparing the value obtained by multiplying power generation by 0.424 kgCO ₂ /kWh.

In addition, the emission factor and emission calculation unit 143 calculates the carbon dioxide emission by power generation resource for the total monthly electricity consumption even when there is no hourly meter reading data and there is only monthly electricity consumption (remote meter reading is not performed). For this purpose, the standard share of each generation resource by time/day/month is obtained. By using the standard share for each power generation resource, the standard production for each time period is calculated. Based on the above results, the standard emission factors and emissions are calculated by time/day/month. If the transmission loss rate and power generation loss rate are applied 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 share of power generation resources by time/day/month is calculated and applied by calculating the average share of power generation resources in the preceding 4 weeks for each time and day of the week in the case of weekdays. The same is true for holidays.

The standard production share (SR) for each power generation resource can be defined by the following formula.

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

As a result of calculating the output by power generation resource by reflecting the standard production share of each power generation resource, it is possible to calculate the actual carbon emission by time period by accurately applying the carbon emission coefficient for each raw material and energy production. Trend can be analyzed. As shown in the formula below, the carbon emission for each time period can be calculated as the sum of the carbon emissions for each power generation resource for each time period.

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 accurately apply the carbon emission coefficients for each raw material and energy production to calculate the actual carbon emission for each time period. . Therefore, it is possible to analyze the carbon emission trend for each power generation resource by time period. As shown in the formula below, the carbon dioxide emission (C _h ) can be calculated by the sum of the carbon emissions for each power generation resource for each time period.

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 of the oil conversion coefficient based on the calorific value ratio of 1 kg of crude oil to the calorific value of each power generation resource.

Therefore, the standard environmental cost coefficient is calculated by applying the social cost of carbon ( _SCC ) to the carbon dioxide emission (Ch ) for each time period.

In other words, the social cost of carbon (SCC) is a quantitative measure developed to quantify climate change, and means the net economic cost of carbon dioxide emissions, and the money of damage per unit of carbon dioxide emissions (ton). It is a negative estimate. The US EPA (Environmental Protection Agency) has been using the SCC estimate since 2008 to analyze the impact of carbon dioxide. This is shown in a table as follows.

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

In addition, business sites, buildings, and power consumer terminals provide customer authentication and functions to store and utilize data in XML (Extensible Markup Language) to use this information.

The output unit 160 performs a function of displaying information processed by the analysis classification block 130 , the calculation block 140 , and the disclosure unit 150 .
