To an apparatus and method for operating a plan. In other words, the present invention is based on the electronic electricity meter (AMI) infrastructure, which is essential for the construction of a national smart grid environment, and the time limit of the system and the total cost (power supply cost (variable cost + fixed cost) + appropriate investment return rate) of the variable cost reflecting market (CBP). Based on various electricity rate determination factors, such as the unit price (eg, differential rate plan) of the sales company calculated on the basis of), sales unit price is recalculated in real time, and the sales company's profit increases and decreases even when the real-time plan is applied.

It's about how.

Power supply and demand under the Smart Grid environment, such as the National Smart Grid Roadmap, the Basic Law on Intelligent Grid, and the Basic Plan on Intelligent Grid, are designed to improve the operational efficiency of distributed power sources such as photovoltaic and wind power, and to improve energy efficiency such as international oil prices. The paradigm of power supply and demand has been shifted toward the efficient and rational use of national energy by inducing power supply patterns to consumers by reflecting fuel cost variability for each power generation source in which import costs change in real time. .

Previously, supply-side demand management (SSM), a basic supply and demand plan, expanded the power supply facilities based on long-term demand forecasting to meet power demand, but failed to predict demand (climate change, abnormal temperature, etc.) and environment. Due to delays in the construction of power plants due to increased protection and Nimbi phenomena, and the safety of nuclear power due to the Fukushima nuclear accident in Japan, the demand for power supply through the expansion of supply capacity is in reality difficult.

In addition, as experienced in the circular blackout of Korea's colostrum on September 15, 2011, it is well known that the balance between supply and demand is essential and difficult to store. In the current situation where the government regulates tariff levels, it is difficult to induce rational energy use by realizing electricity tariffs in the short term.

In order to solve this problem, conventionally, a technology for simulating a user's expected electric charge to select the cheapest rate system has been studied. For example, Korean Patent Publication No. 10-2010-0037430 (name: contract power and electricity rate calculation simulation system, and its implementation method) is the maximum using the annual usage and daily use time for each model of electrical equipment selected by the customer Calculate the electricity demand, multiply the maximum electricity demand by the expected growth rate in the future and apply the actual electricity rate to the contract power to simulate the electricity rate to select the cheapest rate system.

In addition, Korean Patent No. 10-1163561 (name: real-time electricity rate display device and method) obtains the electricity consumption of the customer in real time, calculates and displays the electricity rate.

In this way, the prior art can reduce the overall power consumption of the consumer by providing a choice of low-cost rate according to the set electricity plan or by displaying the real-time electricity rate, but the reduction and demand of peak power during peak hours due to the application of the collective plan There is a problem with the transfer.

In addition, it is difficult to reduce power consumption during peak periods, resulting in additional costs such as stable power supply and construction of a power plant to cover peak power of an instantaneous power system.

The present invention has been proposed to solve the above-mentioned problems, and calculates and provides a real-time rate by using the real-time unit price of the power rate plan calculated by reflecting the time limit system price of the variable cost reflecting market and the unit price of the sales company An object of the present invention is to provide an apparatus and method for operating a real-time rate plan using a system time limit price of a variable cost reflecting market.

That is, the calculation unit 150 calculates the reference load usage by day (Mon, Tue ~ Fri, Sat, Holiday). At this time, the calculation unit 150 calculates the reference load usage using a 10-day average on Tuesday and Friday, and calculates the reference load usage using a 6-day average on Mondays, Saturdays, and holidays. That is, the calculation unit 150 calculates the reference load usage using a six-day average except for the maximum and minimum loads of the 10 days before the Tuesday through Friday, and the last 6 days for the Monday, Saturday and public holidays. Calculate the reference load capacity using the 4-day average except for each of the maximum and minimum loads.

Here, the CBL rate is a value that is applied to the current rate based on the calculated CBL value, the real-time rate is the real-time rate for each time zone, Load is the actual usage for each time zone, CBL is the CBL usage for each time zone.

The calculation unit 150 calculates the adjustment coefficient β for generating the selling price for each hour of the next day by mixing the time limit system price (SMP) of the variable cost reflecting market and the selling company electric power selling price based on the total cost. Here, the adjustment coefficient β is a value for adjusting the seller's rate level and the real-time rate level so as not to be biased to either of the interested parties due to the real-time rate system. As a result, the sales company's profit increase does not occur due to the difference in sales price by time zone, but consumers can save electricity bills due to the difference in sales price by time zone when they use the time zone that applies relatively low sales price. Nationally, the reduction of power demand in the maximum load time can reduce the energy cost (especially the LNG fuel cost used in peak load).

The calculator 150 calculates an adjustment coefficient β for each customer based on the information stored in the storage 130. That is, the calculation unit 150 adjusts the adjustment factor (β) for each customer based on the basic base rate and usage rate unit price of the sales company, the SMP for each hour of the power exchange, and the base base unit price rate for the real-time rate operation. Calculate

To this end, the calculation unit 150 recalculates the basic base rate unit price. That is, the calculation unit 150 is a duplex fee that is currently applied by the sales company when calculating the electric bill [basic rate: fixed cost (equipment investment cost, depreciation cost, etc.) recovery purpose / consumption fee: variable cost (international oil price, LNG, etc.) recovery purpose] In order to improve the rationality of base rate unit cost, the real-time tariff system is one of the methods of distinguishing fixed and variable costs from total cost when calculating power supply cost. Based on the annual fixed cost, peak load) y value, the distribution cost, the distribution cost, the actual rate of return on investment is calculated based on the type of base rate (see Figure 6).

Of course, the base rate unit price may be flexibly applied, such as applying the current base rate unit price and the real time rate unit base rate unit price in order to operate a reasonable and efficient real-time plan such as maximizing demand response.

At this time, Green-Method is an appropriate basic rate calculation method based on the general cost calculation standard (KDI recommended method of 2005), which divides the fixed cost incurred by the electricity system into the fixed cost per kWh due to sales volume and the fixed cost per kW due to maximum power. After that, the fixed cost is distributed by multiplying the maximum power by the type and the sales volume. The basic rate calculation formula using the Green-Method is expressed as Equation 2 below.

Here, K is the amount of power used annually, D is the sum of the maximum power for each contract type, C is the total annual fixed cost, P is the peak load, x is the KWh unit price, y is the kW unit price.

The calculation unit 150 calculates the adjustment coefficient β for each time zone by substituting the calculated base rate unit price and the information stored in the storage unit 130 into the following equation (3).

Here, A is the current base rate unit price, B is the real-time rate base rate unit price, C is the current usage rate unit price, D is the load of the time of the same month last year (or next day demand forecast load). Here, D may apply the next day demand forecast load (that is, the power generation stage, the power transmission stage, etc.) as the load during the same month of last year (or the next day demand forecast load) in order to improve the real-time rate operation efficiency.

The calculation unit 150 adjusts the time-based adjustment coefficient of the time unit based on the system limit price stored in the storage unit 130, the basic base price and the usage fee unit price, the time-based system limit price, and the real-time plan type base rate unit price (β). ) Create a master for creation.

The calculation unit 150 calculates the base rate unit price field by multiplying the current base rate unit price [A] by subtracting the real-time rate base unit price [B] and multiplying the load by the same time period last year (or next day's demand forecast load) [D]. do.

The calculation unit 150 subtracts the current usage fee unit price (h) [C] from the system time limit price (smp (h)) for each time period, and then multiplies the load for each time zone in the same month of the previous year (or the demand forecast for the next day) [D]. Calculate the unit of usage fee unit price.

The calculation unit 150 calculates the adjustment coefficient for each tariff by using the calculated basic tariff unit price field, usage fee unit price field, and last year's load in the same month. Hereinafter, the configuration in which the calculation unit 150 calculates the adjustment coefficient will be described in detail by dividing the plan.

1) Contract type of C-RTP plan

The calculation unit 150 divides the load amount (or demand demand load for the next day) [D] for each time zone during the same month of the previous year into a maximum peak, a middle peak, and a non-peak. That is, the calculation unit 150 divides the maximum peak time zone, the middle peak time zone, and the non-peak time zone according to the amount of load for each time zone during the same month of the previous year (or the demand demand for the next day).

The calculation unit 150 sums the calculated basic rate unit price field and the usage rate unit price field, and then divides by the sum of the loads for each year in the same year of the maximum peak time period (or the demand forecast load for the next day), and then the maximum peak time. Calculate the coordination coefficient for each unit.

The calculation unit 150 sums the calculated basic rate unit price field and the usage rate unit price field, and then divides the load by the year-on-year time zone (or the next-day demand forecast load) in the middle peak period, and divides the time of the intermediate peak period. Calculate the coordination coefficient for each unit.

The calculation unit 150 adds the calculated basic rate unit price field and the usage rate unit price field, and then divides by the sum of the loads for each non-peak period during the same month of the previous year (or the next-day demand forecast load) for the non-peak time. Calculate the coordination coefficient for each unit.

The calculation unit 150 calculates the daily adjustment coefficient β by summing up the calculated time-phase adjustment coefficient of the maximum peak, the time-phase adjustment coefficient of the intermediate peak, and the time-phase adjustment coefficient of the non-peak, respectively.

2) Contract type other than contract type of C-RTP rate plan

The calculation unit 150 calculates a sum of loads (or demand demand loads for the following day) during the same month of the previous year as a single time of the maximum load. The calculation unit 150 calculates the adjustment coefficient for each time period by adding the basic charge unit price field and the usage charge unit price field and dividing the calculated sum by the calculated total value. The calculation unit 150 calculates the daily adjustment coefficient β by summing the calculated time-dependent adjustment coefficients.

3) Plans other than C-RTP plans (e.g. RTP, real-time TOU, T-RTP)

The calculation unit 150 calculates the sum of the loads (or demand for the next day's demand forecast load) [D] for the same time period of the previous year of the entire time zone regardless of the current contract type. The calculation unit 150 calculates the adjustment coefficient for each time period by adding the basic charge unit price field and the usage charge unit price field and dividing the calculated sum by the calculated total value. The calculation unit 150 calculates the daily adjustment coefficient β by summing the calculated time-dependent adjustment coefficients.

The setting unit 170 sets the selling price for each time period by adding or subtracting the adjustment coefficient (that is, the time adjustment coefficient and the daily adjustment coefficient) calculated by the calculation unit 150 to the system limit price (SMP) received from the power exchange. . That is, the setting unit 170 considers RTP, real-time TOU, and T-RTP by considering the selling price, supply voltage, contract power, operation purpose, and ease of change of the consumer power usage pattern calculated by applying the adjustment factor β. It is divided into C-RTP (RTP + CPP) and resets the selling price by time zone. In this case, in order to control the level of electricity price fluctuations of the real-time rate, a one part method having a relatively high electric charge volatility or a second part method having a relatively small electric charge volatility is selected and applied.

Hereinafter, the setting unit 170 will be described in detail by dividing the configuration for resetting the selling price per time zone for each tariff. At this time, in the description related to the technology for resetting the selling price per time zone in the setting unit 170, there is no difference other than the sales rate application rate (50 to 80%) when applying the 1 part plan or the 2 part plan. Explain by reference.

1) RTP plan

The RTP plan applies mainly to low-voltage customers who exceed 10kW contract power and high-voltage customers.The RTP rate system is a real-time plan that re-determines the selling price by using the time-limit system differential price pattern in the variable reflecting market. As shown in 7.

If the application date is a public holiday, the setting unit 170 calculates the current usage fee unit price as a real-time plan regardless of the daily adjustment coefficient. Here, the application of the current usage fee unit price on public holidays is intended to mitigate the risk of rapid rate fluctuations of consumers when implementing real-time plans such as real-time TOU, T-RTP, C-RTP as well as RTP plans. Real-time plans can be applied, including public holidays after the consumer's awareness of the plans. Of course, the setting unit 170 may calculate the RTP unit price for each weekday to be described later as a real-time plan according to the selection.

When the application day is a weekday (including Saturday), the setting unit 170 calculates the RTP unit price for each time zone by using the time limit system price and the daily adjustment coefficient. At this time, the setting unit 170 calculates the RTP unit price for each time zone by substituting the time limit system price per day and the daily adjustment coefficient into Equation 4 below. Here, the calculated time slot RTP unit price is used for the real-time TOU plan and T-RTP plan to be described later.

Here, SMP _d (h) is the systematic limit price in the h time period, and β is the daily adjustment coefficient.

The setting unit 170 calculates the real-time RTP unit price using the calculated RTP unit price for each 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 mainly to residential customers and low-voltage customers who are under contract power of 10kW, and the real-time plan re-determines the selling price considering the ease of changing the power usage pattern (high price → low price). The selling price for each time slot is as shown in FIG. 8.

If the application date is a public holiday, the setting unit 170 calculates the current usage fee unit price as a real-time plan regardless of the daily adjustment coefficient. Of course, the setting unit 170 may calculate the real-time TOU unit price of the weekday to be described later as a real-time plan according to the selection.

The setter 170 sorts in descending order the time-based RTP unit price calculated using the time limit system and the daily adjustment coefficient in the case of weekdays (including Saturdays).

First, when the season is not the winter season (ie, summer, spring, autumn), the setting unit 170 calculates the average of the RTP unit prices for each of the first to fifth rank time zones as the real-time TOU unit price of the maximum load time zone. Calculate the average of the RTP unit prices for each of the 6th to 14th time zones as the real-time TOU unit price for the medium load time zone, and the average of the RTP unit prices for the time zones of the 15th to 24th time zone as the real-time TOU unit price of the light load zone do.

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

If the season is winter (that is, winter), the setting unit 170 calculates the average of the RTP unit prices for each of the first to sixth time zones as the real-time TOU unit price of the maximum load time zone, and the seventh to the fourteenth places for the winter season. The average of the RTP unit prices for each of the time zones is calculated as the real-time TOU unit price of the medium load time zone, and the average of the RTP unit prices for the time zones of the 15th to 24th ranks is calculated as the real-time TOU unit price of the light load time zone.

The setting unit 170 calculates an average unit cost for each load time period in the winter season by using Equations 8 to 10 below. Here, DOR _i in Equations 9 to 11 is an RTP unit price for each time zone of the corresponding time zone.

The setting unit 170 calculates the monthly real-time TOU fee by substituting the calculated real-time TOU unit price and time-based usage amount into Equation 12 below.

Here, 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 of the medium load time zone, B is the medium load time zone usage, L is the average unit price of the light load zone, and C is Light load time zone usage.

In more detail, the setting unit 170 calculates the monthly real-time TOU fee by substituting the calculated real-time TOU unit price and the amount of the non-winter time (that is, summer, spring, autumn) into the following equation (13).

The setting unit 170 calculates the monthly real-time TOU fee by substituting the calculated real-time TOU unit price and the amount of usage during winter time (that is, winter) into the following equation (14).

The real-time TOU plan is based on the assumption that it is difficult for small-capacity customers to change the power consumption pattern according to the selling price that changes every hour. ) And apply real-time usage unit price. However, in the case of winter (that is, November to February of the following year), different seasons and power system demand results (load patterns) are different, and thus they are separately applied as shown in FIG. 9. In the three-hour division selling price application method, it is possible to reduce the electric power bill and the maximum demand power of the power system by changing the power usage pattern in advance by recognizing the maximum load time when power demand is concentrated.

3) T-RTP Plan

The T-RTP plan is mainly applied to low-voltage customers and contracted customers under 10kW and high-voltage customers, and is a real-time plan for refining the selling price for the purpose of constant demand management, and the selling price for each time slot is as shown in FIG. 10. . In this case, the unit price application reference table used to calculate the T-RTP fee is as shown in FIGS. 11 and 12.

The T-RTP plan is similar to the three-hour segmentation criteria and the selling price calculation method of the real-time TOU plan, but the difference in daily SMP is small and the occupancy cost is different (the maximum load (5 hours, 20%) and middle time). Load (9 hours, 38%), light load (10 hours, 42%)). Accordingly, as shown in FIG. 13, the selling unit price by load time period is calculated for the demand management purpose fee type operation because the selling unit price by load time period is insignificant, and the TOU differential coefficient is calculated based on the occupancy ratio of the daily load time period. After the calculation, the selling price is finally recalculated.

If the application date is a public holiday, the setting unit 170 calculates the current usage fee unit price as a real-time plan regardless of the daily adjustment coefficient. Of course, the setting unit 170 may calculate the T-RTP unit price for each weekday, which will be described later, in a real-time plan according to a selection.

In the case of weekdays (including Saturdays), the setting unit 170 divides the time-based RTP unit price calculated using the system time limit and the daily adjustment coefficient into time zones of maximum load, medium load, and light load, and averages each load time period. Calculate the unit price. That is, the setting unit 170 calculates the average unit price of the maximum load time zone, the average unit price of the middle 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 for each load time 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 the i-hour, 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-hour, the intermediate load time, L _d is the average unit price of the light load time, and L _i is the unit price of the i-hour light load time.

The setting unit 170 calculates the RTP unit cost share by load time period by dividing the calculated average unit price by load time period by the sum of average unit costs by load time period. At this time, the setting unit 170 calculates the RTP unit cost share for each load time using Equation 18 below. Here, H _% is the RTP unit cost share of the maximum load time, H _d is the average unit price of the maximum load time, M _% is the RTP unit price 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.

The setting unit 170 calculates the first selling price (1stT-RTPd (h)) of the first T-RTP time zone by using the sum of the RTP unit price for each time zone, the share of the RTP unit price for each load time zone, and the number of hours for each load time zone. This may be expressed as Equation 19 below.

The setting unit 170 calculates the unit price difference for each first T-RTP time zone by dividing the calculated selling price for each first T-RTP time zone by the average unit price for each load time zone. This may be expressed as Equation 20 below.

Here, Hp is the unit price differential rate of the first T-RTP time zone of the maximum load time zone, 1 ^st T-RTP _d (H _d ) is the selling price of the first T-RTP time zone of the maximum load time zone, H _d Is the average unit price of the peak load hour. M _p is the unit price differential rate of the first T-RTP time zone in the mid-load zone, 1 ^st T-RTP _d (M _d ) is the unit price of the first T-RTP time zone in the mid-load zone, and M _d is Average unit price for the medium load period. L _p is the unit price differential rate of the first T-RTP time zone in the light load time zone, 1 ^st T-RTP _d (L _d ) is the sales price of the first T-RTP time zone in the light load time zone, and L _d is Average unit price for light loads.

The setting unit 170 calculates the second selling price per second T-RTP time slot (2 ^nd T-RTP _d (h)) by multiplying the RTP price per time zone and the differential rate per first T-RTP time zone. This may be expressed as Equation 21 below.

The setting unit 170 divides the sum of the product of the RTP unit price by hour and the load by time period by dividing the sum of the product of the second T-RTP time unit by the unit time and the load by time period to divide the T-RTP adjustment coefficient (α). Calculate This may be expressed as Equation 22 below.

The setting unit 170 calculates the T-RTP unit price for each time period by multiplying the calculated T-RTP adjustment coefficient by the second selling price for each T_RTP time period. This may be expressed as Equation 23 below.

The setting unit 170 calculates a real-time T-RTP fee by using the calculated T-RTP unit price and usage amount for each time period. This may be expressed as Equation 24 below.

In this way, when the T-RTP unit price is calculated and applied, the consumer reduces the maximum load time band power consumption while maintaining the advantages of the real-time TOU calculation method (that is, changing the power usage pattern with the maximum load time perception). The benefits are maximized during the middle load time zone transfer, etc., and it is effective in stably managing the maximum demand power of the power system (ie, reducing the system peak).

4) C-RTP Plan

The C-RTP plan applies mainly to high-voltage customers, and is a real-time plan that recalculates the selling price for the purpose of managing the maximum demand power of the power system during the summer and winter periods. . In this case, the unit price application reference table used to calculate the C-RTP fee is as shown in FIGS. 15 and 16.

As shown in FIG. 17, the C-RTP plan is a real-time peak plan combining a real-time plan (RTP plan) and a peak plan (CPP), and the C-RTP plan applies a real-time fee during the non-peak time period, It is a rate plan that applies a high rate peak rate (about 3 to 5 times the real time rate).

Unlike the real-time plan type (ie RTP, real-time TOU, T-RTP), C-RTP plan calculates the probability of generating the maximum power system load in each time zone based on the maximum peak of power system in the previous year. Using the Probability of Contribution to Peak (PCP) method, the total cost is divided and the current selling price is calculated by classifying the peak time period and the non-peak time period (see Fig. 18). The selling price for each time period is determined during the period.

The setting unit 170 calculates the maximum peak adjustment coefficient, the intermediate peak adjustment coefficient, and the non-peak adjustment coefficient. This may be expressed as Equation 25 below.

Where β ₁ is the maximum peak adjustment coefficient, β ₂ is the intermediate peak coefficient, β ₃ is the non-peak adjustment coefficient, A is the current base rate, B is the RTP base rate, and C is the maximum peak usage rate. Unit price, D is the maximum peak hourly load, E is the middle peak usage fee, F is the middle peak hourly load, G is the nonpeak peak hourly price, H is the nonpeak hourly load, and SMP is The system price limit for each hour.

The setting unit 170 calculates the unit price of the C-RTP for each time zone using the calculated adjustment coefficient and the system time limit for each time zone. That is, the setting unit 170 calculates the C-TRP unit price in the maximum peak time period by multiplying the maximum peak adjustment coefficient by the system time limit value for each time zone, and multiplies the mid-peak adjustment coefficient by the time limit system price value by the time period, C- The TRP unit price is calculated, and the C-TRP unit price in the non-peak time period is calculated by multiplying the non-peak adjustment coefficient by the time limit system price. This may be expressed as Equation 26 below.

The setting unit 170 is a C-RTP plan is applied and the planned time is set, and when there is a difference in the execution time compared to the planned time, additionally performs a procedure for refinancing the selling price.

To this end, the setting unit 170 detects the reference load for each load reference and the planning / execution time from the storage unit 130. The setting unit 170 adjusts the C-RTP application planning time by 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 using the C-RTP planning time, the C-RTP application month fee days, and the C-RTP application month total days as shown in Equation 27 below.

The setting unit 170 calculates the C-RTP reference income before settlement by multiplying the current selling price by the reference load for each load in order to apply the five C-RTP rates for each load. At this time, the setting unit 170 calculates the pre-settlement C-RTP reference income amount for light load, medium load, maximum load, intermediate peak, maximum peak, and total load. This may be expressed as Equation 28 below.

The setting unit 170 calculates the pre-settlement C-RTP rate earnings from the peak load. That is, the setting unit 170 calculates the pre-settlement C-RTP rate earnings for the maximum peak and the pre-settlement C-RTP rate earnings for the intermediate peak. At this time, the setting unit 170 multiplies the current selling price for the C-RTP rate by applying the planned time for each peak load, the reference load for each peak load, and the execution time for each peak load, the result of pre-settlement C-RTP plan earnings for the peak load To calculate. The setting unit 170 calculates the peak load earnings revenue by adding up the pre-settlement C-RTP tariff earnings for the calculated peak load. This may be expressed as Equation 29 below.

The setting unit 170 calculates the difference in the amount of C-RTP application revenue. To this end, the setting unit 170 calculates the peak load import difference by summing the intermediate peak import difference and the maximum peak import difference. This may be expressed as Equation 30 below.

The setting unit 170 calculates the difference in the amount of C-TRP applied income (plan-performance) by multiplying the difference in peak load income calculated by dividing the sum of the standardized income in the normal load time period by the standard income for each normal load. do. This may be expressed as Equation 31 below.

The setting unit 170 calculates the amount of settlement income for each general load by using the calculated difference between the C-RTP standard income and the amount of C-TRP applied income (plan-performance). That is, the setting unit 170 calculates the light load settlement income by summing the difference between the light load base income and the light load income, calculates the medium load settlement income by summing the difference between the medium load base income and the medium load import, and the maximum load. Calculate the maximum load settlement revenue by adding up the difference between the standard revenue and the maximum load import. This may be expressed as Equation 32 below.

The setting unit 170 calculates the settlement unit cost for each general load by dividing the amount of the settlement income for each general load by the reference load for each general load. That is, the setting unit 170 divides the light load settlement income by the light load reference load to calculate the light load settlement price, divides the middle load settlement income by the intermediate load reference load, calculates the middle load settlement cost, and calculates the maximum load settlement income. Calculate the maximum load settlement cost by dividing by the maximum load reference load. The setting unit 170 sets the calculated unit cost for each general load to the selling unit price after the current settlement of C-RTP. This may be expressed as Equation 33 below.

The setting unit 170 recalculates the C-RTP rate adjustment coefficient β and the C-RTP unit price by applying the set C-RTP current settlement and the selling price after the C-RTP rate.

The setting unit 170 may calculate the C-RTP fee (month) by using Equation 34 below.

When applying the C-RTP rate type calculated in this way, the price function is separate from the current demand management program (sales company: weekly notice, designated period / electricity exchange: 1 day before market, etc.) that requires a separate manpower and budget. In order to reinforce the demand management by designing the price unit price (3 to 5 times) higher than the selling price of each type of company based on the maximum demand performance of the electricity system in the previous year (average 3 years) and the demand by time period, It is possible to perform the function of the most efficient demand management program by determining and operating the selling price by time in connection with the rate calculation logic.

However, as the C-RTP plan is set and operated in advance, demand management targets can be changed in accordance with environmental changes such as abnormal temperature (heat wave, cold wave, etc.) and power plant failures. Fee settlement is essential. In other words, according to the design criteria of the C-RTP plan (PCP method, etc.), the peak price unit price higher than the normal rate is applied to the system peak estimated time zone, and the non-peak rate price lower than the normal rate is applied, and then the design standard time is not applied. We can maintain neutrality by adjusting the difference between the design reference time and the performance time by discounting the selling price of the mid-load and light-loading time zones and adding the mid- and light-loading time selling price when the design time limit is exceeded.

The provider 190 transmits the final selling price corresponding to the customer-specific rate plan to the consumer and the operator in real time through a web portal (smart service portal), a smartphone, or the like, based on the detected selling price per time period. Through this, the operator can query the usage and fee details by date and time, and compare the real-time rate calculation basic factors (SMP, unit price, adjustment factor, etc.) and the real-time rate with the current rate. The user 500 receives the difference between the selling price for each hour and the difference between the previous day and the previous day at 16 o'clock through the web portal, establishes the next day's electricity use plan, manages the use rate, and manages the electricity rate through rational energy use. This results in efficient management of the maximum demand power of the power system, resulting in efficient use of national energy.

The storage unit 130 stores the information received through the communication unit 110 in association with set time intervals (for example, 5 minutes, 1 hour, and daily).

The calculation unit 150 calculates an adjustment coefficient based on the previously stored information (S200). That is, the calculation unit 150 adjusts the adjustment factor (β) for each customer based on the basic base rate and usage rate unit price of the power distributor, the SMP for each time zone of the power exchange, and the recurring base rate unit price for the real-time rate operation. Calculate This will be described below in more detail with reference to FIG. 20.
