The present invention relates to a technology for operating a power plan, and more particularly, to a technology for operating a power plan using real-time marginal price of a variable-rate reflecting market, which provides a reasonable fee for consuming power, And a method and apparatus for operating a rate plan. That is, the present invention is based on an electronic watt-hour meter (AMI) infrastructure that is essential for the establishment of a country-based smart grid environment, and is based on the marginal cost and total cost (power supply cost (variable cost + fixed cost) ), The price of the sales company is calculated by real time based on various electricity rate determining factors such as the unit price of the sales company (such as the differential pricing system according to the timing), and even when the real-time plan is applied, A real-time plan operation device using the systematic marginal price of the variable-rate reflecting market that can maintain the neutrality with the current charge so that the increase and decrease of the cost of the consumer is not biased, It is about the method.

Until now, electricity demand has been met by expanding the power supply facilities based on long-term demand forecasts with supplier-oriented demand management (SSM), which is the basic plan for power supply and demand. However, In view of the delay in construction of the power plant due to the protection and NIMBY phenomenon, and the safety issue for nuclear power due to the accident at the nuclear power plant in Fukushima, Japan, there is a real difficulty in meeting the electricity demand through the expansion of the supply capacity.

[

The real-time plan operating apparatus 100 provides the real-time plan to the users 500 using the information transmitted from the power exchange server 200, the power sale company server 300 and the smart grid system 400. That is, the real-time plan operating apparatus 100 receives the system limit price SMP of the variable-rate reflecting market (CBP) transmitted from the power exchange server 200, the selling unit price transmitted from the electricity-selling company server 300, And the power consumption of the user 500 transmitted from the system 400, and provides the calculated price to the users 500.

2, the real-time plan operating apparatus 100 includes a communication unit 110, a storage unit 130, a calculation unit 150, a setting unit 170, and a providing unit 190 .

The communication unit 110 receives information for calculating the selling unit price by time from the power exchange server 200 through the network. At this time, the communication unit 110 receives from the power exchange server 200 the information including the next day system marginal price (SMP), the electricity demand demand for each time period, and the like.

The communication unit 110 receives information for calculating the selling unit price by time from the power sales company server 300 through the network.

The communication unit 110 receives information for calculating the selling price per unit of time from the smart grid system 400 through the network. At this time, the communication unit 110 receives information including a power usage amount by a customer using a common information model (CIM) implemented based on the IEC standard.

The storage unit 130 receives and stores information received from the power exchange server 200, the power sales company server 300, and the smart grid system 400 from the communication unit 110. At this time, the storage unit 130 associates and stores the information received from the power exchange server 200 and the power sales company server 300 on a daily and monthly basis, and stores information received from the smart grid system 400 in real time And stores them in association with each other.

The storage unit 130 receives from the communication unit 110 the information including the next day's marginal price SMP and the electricity demand demand for the previous year from the power exchange server 200, And stores them in association with each other. That is, the storage unit 130 stores and correlates the systematic marginal price (SMP) and the power market information of the next day, which are determined at 15 o'clock on the basis of the power generation cost of each generation company, in real time. As shown in FIG. 3, the storage unit 130 stores electricity market information including a systematic marginal price including a price date, a price per unit time, etc., and demand data, power generation unit power, do. In this case, the storage unit 130 stores systematic marginal prices in association with each other on a daily basis, and stores and stores the power market information at intervals of five minutes or one hour.

The storage unit 130 receives information (that is, information received from the power sales company server 300) including the basic unit price per customer, the unit price of the usage rate, the summer maximum demand power, the winter maximum demand power, It is stored in association with monthly unit. That is, the storage unit 130 reserves and stores in advance data having essential elements or less variability in the calculation of the real-time rates such as the basic basic information of the customer and the basic basic charge of the electricity bill and the price of the charge rate. The stored information is used to check whether there is data fluctuation while the real-time plan operation process is in progress. When the summer and winter demand management plan is implemented, the power system status is linked and stored in real time. 4, the storage unit 130 stores customer contract items including customer number, contract power, contract type, meter reading date, contract power, contract type (expansion, partial termination, And the current state of the electric power system including the demand forecast, the demand performance, the reserve ratio status, and the like, including the current billing details including the billing power, the selling unit price (load time zone, season), and the like. Here, the storage unit 130 stores the customer contract details, the customer contract changes, and the current billing details in association with each other on a day-by-day basis, and stores the power system status in association with each other at intervals of five minutes or one hour.

The storage unit 130 receives and stores information including the amount of power used by the customer from the communication unit 110. That is, the storage unit 130 stores a 15-minute power usage amount in real time from an electronic watt-hour meter (AMI) installed in a consumer. The storage unit 130 receives and stores a reference baseline load (CBL) from the calculation unit 150. 5, the storage unit 130 stores the real time electricity price information including the customer number, the meter reading value, and the measurement time, the real time price information including the customer number, the application date, and the unit price, , The application date, and the amount of usage (CBL) including the usage amount. In this case, the storage unit 130 stores and stores the electric power usage amount for each call at 5 minute intervals or 15 minute intervals, and stores the real time price information and the reference load usage amount (CBL) for each day in association with each other.

The calculation unit 150 calculates the reference load usage amount CBL using the information stored in the storage unit 130. [ In other words, the calculating unit 150 calculates the load usage based on the day of the week (month, Tuesday to Friday, Saturday, and holiday). At this time, the calculating unit 150 calculates the reference load usage by using the 10-day average on Tuesdays to Fridays, and calculates the reference load usage by using the 6-day average for the months, Saturdays, and holidays. In other words, the calculation unit 150 calculates the reference load usage using the 6-point average except for the maximum and minimum load of 10 days immediately preceding the 10-day immediately before the load, and for the 6th day immediately preceding the month, The reference load usage is calculated by using 4 matching averages excluding one maximum and minimum load among the loads.

Here, the CBL rate is a value based on the calculated CBL value based on the current rate unit price, the real-time rate is the real-time rate according to the time, the load is the actual usage amount per time period, and the CBL is the CBL usage amount per time.

The calculation unit 150 calculates the adjustment coefficient β for generating the selling unit price by the next day's time slot by mixing the systematic marginal price SMP of the variable-ratio reflecting market with the selling cost of the selling company based on the general cost. Here, the adjustment factor (β) is a value for adjusting the level of the sales company fee and the price of the real-time rate plan so that they are not biased either to the sales company or the consumer who is the interested party due to the implementation of the real-time rate plan. As a result, there is no increase in the sales revenue of the sales company due to the difference in the selling price per hour. However, when the consumer changes the selling price to the time zone in which the relatively low selling price is applied, At the national level, it is possible to reduce energy costs (especially the cost of LNG fuel used in peak load) through peak load time reduction.

The calculation unit 150 calculates an adjustment coefficient β for each customer based on the information stored in the storage unit 130. In other words, the calculation unit 150 calculates the adjustment coefficient (β) for each customer based on the basic basic charge and the basic charge price of the sales company, the SMP of the power exchange at the time of day, .

For this, the calculating unit 150 recalculates the basic basic charge price. That is, the calculating unit 150 calculates the target fee for calculating the electricity bill at the current sales company [basic charge: fixed cost (facility investment cost, depreciation cost, etc.) collection purpose / usage charge rate: variable cost (international oil price, LNG, In order to improve the rationality of the calculation of the basic price, the real-time plan is based on the Green-Method (power transmission rate, annual maximum power, Annual fixed cost, peak load) Calculate the basic unit charge price (see FIG. 6) based on y value, distribution allowance, sales allowance, and actual rate of return on investment.

Of course, basic rate rates can be applied flexibly, for example, by applying the current basic rate and the real-time rate to the basic rate in order to operate a real-time and efficient real-time rate plan such as maximizing demand response.

In this case, the Green-Method is divided into a fixed cost per kWh attributable to the sales volume and a fixed cost per kW due to the maximum power due to the sales amount of the power system based on the optimal basic rate calculation method based on the general cost accounting standard (2005 KDI recommendation method) After that, the fixed cost is distributed by multiplying the maximum power and sales volume by type. The basic fare calculation formula using the Green-Method is expressed by the following equation (2).

In the description related to the technique for resetting the selling unit price by time in the setting unit 170, there is no difference other than the application rate of the real-time rate unit selling price (50 to 80%) when the one-unit or two-unit rate system is applied. I explain it as a standard.

1) RTP plan

RTP tariffs are mainly applied to low-voltage customers whose contract power exceeds 10kW and high-voltage customers. It is a real-time rate plan that sets the selling unit price using a differential pattern of systematic marginal price by time of the variable-rate reflecting market. As shown in FIG.

The setting unit 170 calculates the unit price of the current usage rate by the real-time plan regardless of the daily adjustment factor when the application date is a holiday. In order to reduce the risk of rapid rate change of consumers in real-time payment system such as real-time TOU, T-RTP, C-RTP as well as RTP plan, Improvement of the consumer's awareness of the fare plan, etc.), and the real-time plan including the holiday can be applied. Of course, the setting unit 170 may calculate the RTP unit price for each time period of the weekday, which will be described later, on a real-time plan basis according to the selection.

The setting unit 170 calculates the RTP unit price for each time period by using the systematic marginal price and the daily adjustment coefficient for each time period when the application day is on a weekday (including Saturday). At this time, the setting unit 170 calculates the RTP unit price for each time period by substituting the systematic marginal price for each time period and the daily adjustment coefficient into the following equation (4). Here, the calculated RTP unit price is used for a real-time TOU plan and a T-RTP plan to be described later.

The setting unit 170 calculates the real time RTP unit price using the calculated RTP unit price by time period. At this time, the setting unit 170 calculates the real time RTP unit price using Equation (5) below.

2) Real-Time TOU Plan

The real-time TOU plan applies to residential customers and low-voltage customers who have contracted power of 10kW or less, and it is based on a real-time charge plan that sets the unit price of the sales unit considering the ease of changing the power usage pattern of consumers (high unit time zone → low unit time zone) And the unit selling price by time is as shown in FIG.

The setting unit 170 calculates the unit price of the current usage rate by the real-time plan regardless of the daily adjustment factor when the application date is a holiday. Of course, the setting unit 170 may calculate a real-time TOU unit price of a weekday, which will be described later, as a real-time plan according to the selection.

The setting unit 170 arranges the RTP unit prices for each time period calculated in descending order using the systematic marginal price by time zone and the daily adjustment coefficient for weekdays (including Saturdays).

First, if the season is not winter (i.e., in the case of summer, spring, and autumn), the setting unit 170 calculates an average of the RTP unit prices for the first to fifth rank time zones as a real time TOU unit price of the maximum load time zone The average of the RTP unit prices for the 6th to 14th ranked time zones is calculated as the real time TOU unit price for the middle load time zone and the average of the RTP unit prices for the 15th to 24th time zones is calculated as the real time TOU unit price for the light load time zone do.

The setting unit 170 calculates an average unit price for each load time period in summer, spring, and autumn using the following equations (6) to (8). Here, DOR _i in Equations (5) to (7) is the RTP unit price for the time zone in the corresponding time zone.

When the season is winter (that is, winter), the setting unit 170 calculates the average of the RTP unit prices for the first to sixth rank time zones as the real time TOU unit price in the maximum load time zone in the case of winter, The average of the RTP unit prices for the respective time periods is calculated as the real time TOU unit price of the intermediate load time zone, and the average of the RTP unit prices for the 15th to 24th time units is calculated as the real time TOU unit price at the light load time zone.

The setting unit 170 calculates the average unit price of the winter load time group by using the following equations (8) to (10). Here, DOR _i of Equation (9) to Equation (11) is the RTP unit price for the time zone in the corresponding time zone.

The setting unit 170 calculates the monthly real time TOU charge by substituting the calculated real time TOU unit price and the usage amount per time period into the following equation (12).

Where H is the average unit price of the maximum load time zone, A is the maximum load time zone usage, M is the average unit price in the intermediate load time zone, B is the intermediate load time zone usage, L is the average unit price in the light- It is the light load time zone usage.

More specifically, the setting unit 170 calculates the monthly real-time TOU rate by substituting the real-time TOU unit price and usage calculated during the non-synchronous time (summer, spring, autumn) into the following equation (13).

The setting unit 170 calculates the monthly real time TOU rate by substituting the real time TOU unit price and the usage amount calculated during the winter time (i.e., winter) into the following equation (14).

Under the assumption that it is difficult to change the pattern of power consumption according to the unit price of a small-capacity customer changing every time period, the real-time TOU plan is a system in which the demand for power system is adjusted to 3 hours a day ), And real-time usage charge rate is applied. However, in the case of winter (that is, from November to February of next year), the demand for power system (load pattern) differs from that of other seasons. Such a three-time-period sales unit price method can reduce the electricity cost of the consumer and reduce the maximum demand power of the power system by changing the power usage pattern by recognizing the maximum load time period in which the power demand is concentrated in advance.

3) T-RTP Plan

The target of the T-RTP plan is a low-voltage customer who is under 10 kW contract power and high-voltage customers, and is a real-time charge system that sets the unit price for the purpose of daily demand management, and the unit price per unit time is as shown in FIG. 10 . At this time, the unit price application reference table used for calculating the T-RTP fee is as shown in FIG. 11 and FIG.

The T-RTP rate system is similar to the real-time TOU rate system in terms of 3-hour time division and sales price calculation method, but the SMP difference by time of day load time is small and the occupancy ratio by load time period is different (non-dynamic maximum load (5 hours, 20% Load (9 hours, 38%), light load (10 hours, 42%)). Accordingly, as shown in FIG. 13, the sales unit price is calculated by calculating the selling unit price per load time zone in order to operate the demand management fee type at all times, and the TOU differential coefficient After the calculation, the selling unit price is finally calculated based on the load time period.

The setting unit 170 calculates the unit price of the current usage rate by the real-time plan regardless of the daily adjustment factor when the application date is a holiday. Of course, the setting unit 170 may also calculate the T-RTP unit price for each time period of the weekday, which will be described later, on a real-time plan basis according to the selection.

The setting unit 170 divides the RTP unit price for each time period calculated by using the systematic marginal price and the daily adjustment coefficient in the case of weekday (including Saturday) into the time zone of maximum load, intermediate load and light load, The unit price is calculated. That is, the setting unit 170 calculates the average unit price of the maximum load time zone, the average unit price of the intermediate load time zone, and the average unit price of the light-load time zone.

At this time, the setting unit 170 calculates the average unit price per load time zone using the following equations (15) to (17). Here, H _d is the average unit price of the maximum load time, H _i is the unit price of i time, which is the maximum load time, M _d is the average unit price of the intermediate load time, M _i is the unit price of the i time, L _d is the unit cost of light load time, and L _i is the unit price of light load time i time.

The setting unit 170 calculates the RTP unit price share by load time group by dividing the calculated average unit price by load time group by the sum of the average unit price per load time group. At this time, the setting unit 170 calculates the RTP unit price occupancy for each load time zone using the following equation (18). Here, _H% is the RTP unit share of the full load time, H _d is the average cost of the full load time, _M% is the RTP unit share of the intermediate load time, M _d is the average unit price of the intermediate load time, _L% Is the RTP unit price share of light load time, and L _d is the average unit price of light load time.

This can be expressed by the following equation (19).

The setting unit 170 calculates the unit price difference rate by the first T-RTP time slot by dividing the calculated unit price of sales by the first T-RTP time slot by the average unit price of each load time slot. This can be expressed by the following equation (20).

Where, Hp is the first T-RTP time slot unit price differential rate _{^{is, 1 st T-RTP d (}} H d) is the first T-RTP time slot selling price of the full load time of the full load time, H _d Is the average unit price of the maximum load time zone. M _p is the first T-RTP time slot unit price differential rate of the intermediate load time, the _{^{1 st T-RTP d (M}} d) is ASP first T-RTP time of medium load zone classified, M _d are It is the average unit price of the intermediate load time zone. L _p is the first T-RTP time slot unit price differential rate _{^{is, 1 st T-RTP d (}} L d) is the first T-RTP time slot selling price of the light load time of the light load time, L _d is It is the average unit price of the light load time zone.

The setting unit 170 calculates the selling unit price (2 ^nd T-RTP _d (h)) by the second T-RTP time slot by multiplying the RTP unit price by time period and the unit price difference rate by the first T-RTP time slot. This can be expressed by the following equation (21).

The setting unit 170 divides the sum of values obtained by multiplying the RTP unit price for each time period by the load for each time period by the sum of values obtained by multiplying the selling price by the second T-RTP time period and the load for each time period to obtain a T-RTP adjustment coefficient . This can be expressed by the following equation (22).

The setting unit 170 calculates the T-RTP unit price by time by multiplying the calculated T-RTP adjustment factor by the selling price per second T_RTP time slot. This can be expressed by the following equation (23).

The setting unit 170 calculates a real-time T-RTP charge using the calculated T-RTP unit price and the usage amount for each time slot. This can be expressed by the following equation (24).

In this way, when the T-RTP unit price is calculated and applied, it is possible for the consumer to reduce the use of the maximum load time zone (i.e., to maintain the maximum load time zone power) while maintaining the advantage of the real time TOU calculation method , Before mid-load time zone, etc.), and it is effective to stably manage power system maximum demand power (that is, reduce grid peak).

4) C-RTP Plan

The application target of the C-RTP tariff is primarily a high-voltage customer, and is a real-time charge system for setting the selling unit price for the purpose of managing the maximum demand power of the power system during the summer and winter periods, . At this time, the unit price application reference table used for calculating the C-RTP fee is as shown in FIG. 15 and FIG.

As shown in FIG. 17, the C-RTP plan is a real-time peak plan that combines a real-time plan (RTP plan) and a peak plan (CPP) It is a rate plan that applies a high peak rate (approximately three to five times the real-time charge).

The C-RTP plan calculates the probability that the maximum power system load will occur for each time of the year based on the maximum peak of the power system in the past year, unlike the real-time plan fare types (ie, RTP, real-time TOU and T-RTP) The total cost is rearranged using the PCP (Probability of Contribution to Peak) method which distinguishes the time zones, and the current selling unit price is calculated by dividing the total cost into the peak time period and the non-peak time period (see FIG. 18) During the period, the unit price is determined by time zone.

The setting unit 170 calculates the maximum peak adjustment coefficient, the intermediate peak adjustment coefficient, and the non-peak adjustment coefficient. This can be expressed by the following equation (25).

Where B ₁ is the maximum peak adjustment factor, β ₂ is the intermediate peak factor, β ₃ is the non-peak adjustment factor, A is the current base rate unit price, B is the RTP base rate unit price, C is the peak peak usage rate D is the maximum peak load per unit time, E is the intermediate peak usage rate unit price, F is the intermediate peak hourly load, G is the non peak usage rate unit price, H is the non peak hourly load, It is systematic marginal price by time zone.

The setting unit 170 calculates the C-RTP unit price for each time period using the previously calculated adjustment factor and the systematic threshold price for each time period. That is, the setting unit 170 calculates the C-TRP unit price at the maximum peak time zone by multiplying the maximum peak adjustment factor by the systematic threshold price for the time period, multiplies the intermediate peak adjustment factor by the systematic threshold price for the time period, The TRP unit price is calculated, and the C-TRP unit price is calculated by multiplying the non-peak adjustment factor by the systematic threshold price for the time period. This can be expressed by the following equation (26).

The setting unit 170 additionally performs a procedure for calculating the price of the sales unit when the application period and the planning time of the C-RTP plan are predetermined and there is a difference in the execution time with respect to the planned time.

For this, the setting unit 170 detects the reference load amount and the plan / trial time for each load reference from the storage unit 130. The setting unit 170 performs C-RTP application planning time adjustment using the detected information. At this time, the setting unit 170 adjusts the planning time for the application days of the C-RTP application month. That is, the C-RTP application planning time is adjusted by using the C-RTP planning time, the C-RTP application monthly charge day, and the C-RTP application total month as shown in the following equation (27).

The setting unit 170 calculates the C-RTP import amount before the settlement by multiplying the current selling price by the reference load per load for the application of the C-RTP charge for each of the five loads. At this time, the setting unit 170 calculates the C-RTP-based import amount before the settlement for light load, intermediate load, maximum load, intermediate peak, maximum peak, and total load. This can be expressed by the following equation (28).

The setting unit 170 calculates the earnings amount of the C-RTP plan before the settlement of the peak load. That is, the setting unit 170 calculates the earnings amount of the C-RTP plan before the settlement for the maximum peak and the earnings amount of the C-RTP plan before the settlement for the intermediate peak. At this time, the setting unit 170 multiplies the current selling price for application of the C-RTP charge by the planning time for each peak load, the reference load for each peak load, and the execution time for peak load, . The setting unit 170 calculates the peak load earnings amount by adding up the earnings amount of the C-RTP plan before the settlement of the calculated peak load. This can be expressed by the following equation (29).

The setting unit 170 calculates the C-RTP applied import difference. To this end, the setting unit 170 calculates the difference in the peak load import amount by adding the difference between the intermediate peak import difference and the maximum peak import amount. This can be expressed by the following equation (30).

The setting unit 170 calculates the C-TRP applicable import difference (plan-performance) by multiplying the difference of the peak load import amount calculated by dividing the sum of the reference import amount of the general load time calculated by the general load and the reference import amount calculated by the general load do. This can be expressed by the following equation (31).

The setting unit 170 calculates the amount of settlement income per general load by using the difference between the calculated C-RTP import amount before the settlement and the C-TRP applied import amount difference (plan-performance). In other words, the setting unit 170 calculates the import amount under the light load by summing the difference between the light-load-based import amount and the light-load import amount, calculates the intermediate load settlement income by adding the difference between the import amount of the intermediate load and the import amount of the intermediate load, Calculate the maximum load settlement income by adding the difference between the reference import amount and the maximum load import amount. This can be expressed by the following equation (32).

The setting unit 170 divides the amount of settlement income per general load by the reference load per general load to calculate the settling cost per general load. That is, the setting unit 170 calculates the unit price of the light load under the light load, the unit load of the light load under the light load, calculates the unit load of the intermediate load by dividing the load of the intermediate load by the load of the intermediate load, Is divided by the maximum load reference load to calculate the maximum load settlement unit price. The setting unit 170 sets the unit price calculated by the general load as the unit price after the C-RTP current settlement. This can be expressed by the following equation (33).

The setting unit 170 recalculates the C-RTP tariff adjustment factor (β) and the C-RTP unit price by applying the set selling price after the current C-RTP settling to the current usage rate unit price of the C-RTP plan.

The setting unit 170 may calculate the C-RTP charge (month) using the following equation (34).

When applying the C-RTP fee type calculated in this way, the current demand management program (sales company: weekly notice, designated period, etc., which requires a separate operating personnel and budget / electricity exchange market: one day before market, etc.) (3 ~ 5years) than the selling price of each type of sales company based on the maximum demand of the power system and the demand by time of the year. By determining and operating the unit price per unit time in connection with the charge calculation logic, it is possible to perform the function of the most efficient demand management program.

However, as the C-RTP plan sets and manages demand management goals, it may change the operating time compared to the design standard time due to environmental changes such as abnormal temperatures (heat waves, cold waves, etc.) It is essential that the fare settlement is followed. In other words, peak peak charge rate is applied to peak peak expected time frame according to the design standard (PCP method, etc.) of C-RTP charge plan. In addition, it is possible to maintain the neutrality by adjusting the difference between the design standard time and the actual performance time by adding the intermediate load and the light duty hour sales unit price and applying the design standard timeout.

The provider 190 transmits the final selling price corresponding to the per-consumer price plan to the consumer and the operator in real time through the web portal (smart service portal) or the smart phone based on the detected selling price per time slot. Through this, the operator can inquire the usage amount and the charge details by date, time, and compare the basic factors (SMP, unit price, adjustment factor, etc.) and real time charge with the current charge. The user 500 receives the difference between the sales unit price and the previous day unit price by the time zone to be applied next day at 16:00 through the web portal to establish the next day power use plan and manages the use performance, , Which can effectively manage the maximum demand power of the power system, resulting in efficient use of national energy.

The setting unit sets the maximum peak adjustment factor, the intermediate peak adjustment factor, and the ratio based on the current basic rate unit price, the RTP basic rate unit price, the load amount per peak of each peak, the usage rate unit price of each peak, Calculating a peak adjustment factor; And
And calculating the C-RTP unit price at each peak time zone based on the maximum peak adjustment factor, the intermediate peak adjustment factor, the non-peak adjustment factor, and the systematic marginal price for each time period by the setting unit A method of operating a real - time rate plan using the system 's marginal price by market. 27. The method of claim 24,
The step of setting the selling unit price per time period includes:
Adjusting the C-RTP application planning time based on the reference load amount, the planning time, and the trial time by the load reference by the setting unit;
The above setting unit multiplies the current sales price by load and the reference load per load for loads including light load, intermediate load, maximum load, intermediate peak, maximum peak, and total load, Calculating an import amount;
The setting unit multiplies the current selling price for the C-RTP charge application by the planning time for each peak load, the reference load for each peak load, and the trial time for each peak load, Calculating a C-RTP rate performance earnings;
Calculating a peak load earnings amount by summing the intermediate peak earnings and the peak earning earnings by the setting unit;
Calculating a peak load import amount difference by summing an intermediate peak import amount obtained by subtracting the intermediate peak earnings amount from the import amount based on the intermediate peak and a maximum peak income amount obtained by subtracting the maximum peak earnings amount from the import amount based on the maximum peak;
By the setting unit, the value obtained by dividing the light load-based import amount, the intermediate load-based import amount, and the maximum load-based import amount by the light load-based import amount, the intermediate load-based import amount, and the maximum load- Calculating a C-RTP applied import difference including a difference in light load, a difference in intermediate load import, and a difference in maximum load import;
Calculating, by the setting unit, the amount of settlement income by the general load including the difference between the reference import amount by the general load and the import amount by the general load, and including the light load settlement income, the intermediate load settlement income and the maximum load settlement income;
Calculating the unit price for the general load including the light load fixing unit price, the intermediate load fixing unit price, and the maximum load adjustment unit price by dividing the normalized load of the general load by the standard load by the setting unit; And
RTP rate adjustment unit and C-RTP unit price based on the unit price of the general load and the current unit price of the C-RTP plan by the setting unit. A method of operating a real - time rate plan using the system 's marginal price by market. 18. The method of claim 16,
In the step of calculating the real-time rate for each rate plan,
Wherein the setting unit calculates a real-time charge for each charge based on the calculated unit price, the time-based charge, and the base charge for each charge plan, and calculates a real-time charge for each charge plan based on the time- Way. 18. The method of claim 16,
Further comprising the step of providing the user with the set selling price per unit time and the real rate per rate plan by the service providing unit to the user.
