Description

Power trading management method and device

[0001] This specification relates to a method for managing power trading, and more specifically, to a method and apparatus for performing and managing power trading bids for the sale of electricity produced from renewable energy power plants.

[0002]

[0003] Renewable energy power plants are facilities that generate electricity using eco-friendly resources such as solar, wind, and hydropower, and they are playing an increasingly important role in ensuring a sustainable energy supply. However, because renewable energy is highly volatile and difficult to predict depending on natural conditions, it is crucial to sell the generated electricity stably and secure optimal prices.

[0004] While the power trading market provides a platform for the efficient trading of such renewable energy, the bidding process is complex and highly competitive. Consequently, power plant operators must analyze a large amount of data to respond to market volatility and formulate optimal bidding strategies. In particular, they must comprehensively consider factors such as generation forecasts, market price trends, and competitor bidding information, which can lead to the consumption of time and resources.

[0005] Existing power trading methods have often relied on fixed bidding systems or passive responses, frequently failing to adequately reflect the characteristics of renewable energy. Therefore, a new power trading bidding management method is required that reflects the characteristics of renewable energy and the renewable energy power trading market to maximize the profits of renewable energy power plants or power generation operators.

[0006]

[0007] The purpose of this specification is to provide a power trading management method and apparatus capable of maximizing the profit of a renewable energy power plant or a renewable energy power generation business operator.

[0068] The memory (12) may include at least one type of storage medium among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory), RAM (Random Access Memory, RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory, ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic disk, and optical disk.

[0069] A power trading management device (1) according to one embodiment may operate in connection with web storage that performs the storage function of memory (12) on the internet. The description of the memory described above is merely an example, and the present disclosure is not limited thereto.

[0070] The communication unit (12) may be a device for wired or wireless communication. The communication unit (12) may transmit data to another device through a network or receive data transmitted from another device.

[0071] In one embodiment, the communication unit (12) can use various wired communication systems such as a public switched telephone network (PSTN), xDSL (x Digital Subscriber Line), RADSL (Rate Adaptive DSL), MDSL (Multi Rate DSL), VDSL (Very High Speed ​​DSL), UADSL (Universal Asymmetric DSL), HDSL (High Bit Rate DSL), and a local area network (LAN).

[0072] In another embodiment, the communication unit (12) may use various wireless communication systems such as CDMA (Code Division Multi Access), TDMA (Time Division Multi Access), FDMA (Frequency Division Multi Access), OFDMA (Orthogonal Frequency Division MultiAccess), SC-FDMA (Single Carrier-FDMA), and other systems.

[0073] The network used for communication between the communication unit (12) and the power exchange server (2) can be configured regardless of the communication mode, such as wired or wireless, and can be configured as various communication networks such as a Local Area Network (LAN), a Personal Area Network (PAN), and a Wide Area Network (WAN). In addition, the network may be the known World Wide Web (WWW).

[0074] The technologies described in this specification can be used not only in the networks mentioned above but also in other networks.

[0075] The power exchange server (2) may be a server operated by the power exchange. The power exchange server (2) may perform a bidding process for purchasing power.

[0076] For example, the power exchange server (2) may receive an initial bid from the power trading management device (1) and other devices according to one embodiment on the day before the trading target date (e.g., June 1) (e.g., May 31). The power exchange server (2) may generate a power generation plan information for the day before, including a planned power generation amount information for each trading hour of the trading target date and a System Marginal Price (SMP) information for each trading hour of the trading target date, by referring to the initial bid.

[0077] The power exchange server (2) can determine the amount of electricity awarded one day in advance for each renewable energy power plant by referring to the initial bids of the power trading management device (1) and other devices.

[0078] The power exchange server (2) can transmit the power generation plan information and the amount of electricity won in the previous day's bid for each renewable energy power plant to the power trading management device (1) and other devices at a predetermined time for announcing the power generation plan (e.g., 6:00 PM on the day before the trading day).

[0079] The power exchange server (2) can receive advance change bids from the power trading management device (1) and other devices according to one embodiment on the day before the trading target date (e.g., June 1) (e.g., May 31).

[0080] In addition, the power exchange server (2) can receive real-time change bids from the power trading management device (1) and other devices according to one embodiment on the day before (e.g., May 31) or on the trading day (e.g., June 1).

[0081] The power exchange server (2) can generate real-time power generation plan information including real-time planned power generation information for each trading hour of the trading target date and real-time SMP information for each trading hour of the trading target date by referring to the bid submitted last among the pre-change bid and real-time change bid.

[0082] In addition, the power exchange server (2) can determine the real-time winning bid amount of each renewable energy power plant by referring to the most recently submitted bid among the pre-change bids and real-time change bids of the power trading management device (1) and other devices.

[0083] The power exchange server (2) can transmit real-time power generation plan information and real-time winning bid power of each renewable energy power plant to the power trading management device (1) and other devices at a predetermined real-time power generation plan announcement time (e.g., 15 minutes before the start time of each trading time of the trading day).

[0084] In addition, the power exchange server (2) can transmit real-time SMP information confirmed for each trading hour of the trading day to the power trading management device (1) and other devices on the next day of the trading day (e.g., June 2).

[0085] After the power trading bidding process is performed by the power exchange server (2), when the renewable energy power plant completes the supply of power equal to the amount of power generated on the trading day on the trading day, the renewable energy power plant (or renewable energy power generation business operator) can receive energy settlement money from the power exchange according to the following formula.

[0086]

[0087]

[0088]

[0089] In other words, the energy settlement amount can be defined as the sum of the previous day's energy settlement amount (the previous day's SMP × the previous day's awarded electricity volume) and the real-time energy settlement amount (real-time SMP × (generation volume on the trading day - the previous day's awarded electricity volume)).

[0090] In [Equation 1], the previous day's SMP, the real-time SMP, or (generation amount on the trading day - the amount of electricity won in the previous day's auction) can be positive or negative. Therefore, the settlement amount can be positive or negative.

[0091] In addition, renewable energy power plants (or renewable energy power generation business operators) may receive additional settlement payments based on fluctuations in output instructions and capacity settlement payments based on effective capacity from the power exchange in accordance with power supply.

[0092] In addition, renewable energy power plants (or renewable energy generators) that sell and supply electricity through power trading bids may be granted Renewable Energy Certificates (RECs). Renewable energy power plants (or renewable energy generators) can earn revenue from the sale of RECs by selling the RECs obtained through electricity supply to other individuals or companies.

[0093] Meanwhile, if the amount of electricity supplied by a renewable energy power plant on the trading day exceeds the winning bid amount or the output indicated by the power exchange by more than the allowable margin, an imbalance penalty may be imposed on the renewable energy power plant (or renewable energy power generator). If an imbalance penalty occurs, the renewable energy power plant (or renewable energy power generator) must pay the penalty amount to the power exchange. If the amount of electricity supplied by the renewable energy power plant on the trading day is smaller than the winning bid amount or the output indicated by the power exchange, an imbalance penalty may not occur.

[0094] Ultimately, the revenue that a renewable energy power plant (or renewable energy power generation business operator) can obtain through the sale and supply of electricity can be calculated by subtracting the imbalance penalty amount from the sum of the settlement amount (energy settlement amount, additional settlement amount, capacity settlement amount) and the REC sales revenue.

[0095] Therefore, in order to maximize the profits of renewable energy power plants (or renewable energy power generation operators) from power supply, it is necessary to increase settlement payments and REC sales revenue and minimize the occurrence of imbalance penalties. In particular, if the settlement payment is negative, and the sum of the settlement payment and REC sales revenue is less than zero, it is advisable not to supply power because a loss will occur due to the power supply.

[0096] Hereinafter, exemplary embodiments in which a power trading management device (1) performs a power trading bid are described with reference to FIGS. 1 to 3.

[0097] FIG. 2 shows an exemplary power trading schedule to which a power trading management method according to one embodiment is applied. FIG. 3 shows an exemplary format of a bid document generated by a power trading management device according to one embodiment.

[0098] A power trading management device (1) according to one embodiment may transmit bids to a power exchange server (2) to sell power generated by a renewable energy power plant to a power exchange. For example, the power trading management device (1) may transmit bids to a power exchange server (2) from one day before the trading day (e.g., May 31) to the trading day in order to sell power generated by a renewable energy power plant at each trading time of the trading day (June 1).

[0099] FIG. 3 illustrates an exemplary format of a bid generated by a power trading management device (1) according to one embodiment. The power trading management device (1) according to one embodiment may generate an initial bid, a pre-change bid, or a real-time change bid having a format as shown in FIG. 3.

[0100] As illustrated in FIG. 3, the bid generated by the power trading management device (1) may include information regarding the date of the transaction (transaction date), the name of the renewable energy power plant (power company), and the type of renewable energy (resource name). Additionally, the bid generated by the power trading management device (1) may include information regarding the technical characteristics of the renewable energy power plant.

[0101] In addition, the bid generated by the power trading management device (1) may include the amount of electricity that a renewable energy power plant can supply (supply capacity) for each trading time (1 to 24) of the trading target date, the minimum amount of electricity that can be supplied (minimum generation capacity) for each trading time of the trading target date, the bidding section for each trading time of the trading target date (first bidding section to tenth bidding section), the supply capacity for each bidding section, and the bid price for each bidding section. Here, trading time 1 may mean from 0:00 AM to 1:00 AM, and trading time 3 may mean from 2:00 AM to 3:00 AM.

[0102] The bid price for each bid section recorded in the bid document generated by the power trading management device (1) can be determined within a price below a predetermined upper limit and a price above a predetermined lower limit.

[0103] For example, a predetermined upper limit may be 0 won, and a predetermined lower limit may be a negative number (e.g., the average spot REC price from two months ago multiplied by -1). This is merely an example, and the upper and lower limits may be set differently depending on the embodiment.

[0104] First, the power trading management device (1) can generate an initial bid document for an initial bid. In one embodiment, the power trading management device (1) can generate an initial bid document using a first predicted power generation value of a renewable energy power plant.

[0105] In one embodiment, the power trading management device (1) can obtain a power generation prediction value calculated by a pre-generated power generation prediction model. Here, the power generation prediction model may be an artificial intelligence model generated by machine learning (e.g., deep learning) based on past hourly weather data (e.g., wind speed, sunlight, temperature, humidity, etc.) and the corresponding power generation data of a renewable energy power plant. For example, the power generation prediction model may be stored in memory (12) or on another server (e.g., a cloud server). The power trading management device (1) can obtain a power generation prediction value for each trading hour of the trading target day that is output when weather prediction data for the trading target day is input into the power generation prediction model.

[0106] In one embodiment, the first power generation prediction value may refer to a power generation prediction value corresponding to the median (or 50th percentile) in the probability distribution of power generation prediction values ​​for each transaction hour output by the power generation prediction model. In one embodiment, the second power generation prediction value may refer to a power generation prediction value corresponding to a higher percentile (e.g., 90th percentile) than the median in the probability distribution of power generation prediction values ​​for each transaction hour output by the power generation prediction model.

[0107] In one embodiment, the power trading management device (1) can obtain a first power generation prediction value for each trading time of a renewable energy power plant calculated by a power generation prediction model. For each trading time, the power trading management device (1) records the first power generation prediction value as the supplyable capacity for each bidding section of the first bidding section, and for each trading time, records the bidding price for each bidding section of the first bidding section as the upper limit.

[0108] In the initial bid document, only the available supply capacity per bid section and the bid price per bid section of the first bid section can be recorded for all transaction times.

[0109] When an initial bid is generated, the power trading management device (1) can transmit the initial bid to the power exchange server (2) during a predetermined initial bidding period (A1).

[0110] In one embodiment, a predetermined initial bidding period (A1) may be determined based on a predetermined initial bidding deadline (B1). For example, the initial bidding period (A1) may be determined to be between 10:00 a.m. on the day before the transaction date (e.g., May 31) and 11:00 a.m., the initial bidding deadline.

[0111] In one embodiment, the power trading management device (1) may transmit a number of initial bids to the power exchange server (2) during a predetermined initial bidding period (A1). The power exchange server (2) may recognize the initial bid submitted last among the number of initial bids as the final initial bid submitted by the power trading management device (1).

[0112] When the power generation plan is determined one day in advance, if the SMP for the previous day is determined to be negative, the energy settlement amount may become negative. In this case, the energy settlement amount for a renewable energy power plant allocated the electricity volume won in the previous day's bid may be finalized as a negative figure.

[0113] However, when an initial bid is submitted with the bid price for each bidding section of the first bidding section recorded as the upper limit for each trading time, the probability of not being awarded may increase when the winning bidder and the amount of electricity awarded are determined by the power exchange server (2) according to the generation plan for the day before. If a renewable energy power plant is excluded from the winning bidder for the day before during the process of determining the generation plan for the day before and is not allocated the amount of electricity awarded, the energy settlement amount for the renewable energy power plant for the day before is determined to be 0 won, thus preventing the phenomenon where the energy settlement amount for the renewable energy power plant for the day before becomes a negative number.

[0114] In one embodiment, when the pre-change bid or real-time change bid described below is submitted, the bid price for each bid section recorded in the pre-change bid or real-time change bid may be smaller than the bid price for each bid section recorded in the pre-bid. Therefore, when an initial bid in which the bid price for each bid section is recorded as an upper limit is transmitted to the power exchange server (2), there is an advantage that when the pre-change bid or real-time change bid is created, the bid price for each bid section can be freely set to a value between the upper limit and the lower limit.

[0115] Next, the power trading management device (1) can generate a pre-change bid using the first power generation amount prediction value and the second power generation amount prediction value.

[0116] In one embodiment, when generating a pre-change bid, the power trading management device (1) can determine whether each trading time is included in the output control occurrence time (e.g., from 7 a.m. to 7 p.m.), which is the time when output control is expected to occur, or in the output control non-occurrence time (e.g., from 7 p.m. to 7 a.m.), which is the time when output control is expected not to occur. The output control occurrence time and the output control non-occurrence time may be set differently depending on the embodiment.

[0117] Additionally, in one embodiment, when generating a pre-change bid, the power trading management device (1) can determine whether each trading time falls within the discharge time of an Energy Storage System (ESS) connected to a renewable energy power plant (e.g., from 11 a.m. to noon or from 5 p.m. to 6 p.m.). The ESS discharge time may be set differently depending on the embodiment.

[0118] In one embodiment, the pre-change bid document may include the supplyable capacity and bid price for each bid section of the first bid section and the supplyable capacity and bid price for each bid section of the second bid section for the transaction time included in the expected time of output control occurrence, and may include the supplyable capacity and bid price for each bid section of the first bid section for the transaction time included in the expected time of non-occurrence of output control.

[0119] In one embodiment, the reference capacity may be set based on the installed capacity of the renewable energy power plant. For example, the reference capacity may be set to the installed capacity of the renewable energy power plant multiplied by 0.12. This is just one example, and the reference capacity may vary depending on the embodiment.

[0120] In one embodiment, when generating a pre-change bid, the power trading management device (1) may, if the trading time is included in the expected time for output control occurrence and the first generation amount prediction value is greater than or equal to a predetermined standard capacity and the trading time is included in the ESS discharge time, record the supplyable capacity per bidding section of the first bidding section as a predetermined first overbid capacity, record the bid price per bidding section of the first bidding section as a lower limit price, record the supplyable capacity per bidding section of the second bidding section as a predetermined second overbid capacity, and record the bid price per bidding section of the second bidding section as an upper limit price.

[0121] In one embodiment, the predetermined first overbid capacity may be a value calculated by combining the first power generation prediction value and the second power generation prediction value according to a predetermined first combination ratio (e.g., 7:3), plus the PCS capacity of the ESS connected to the renewable energy generator. In one embodiment, the predetermined second overbid capacity may be a value calculated by combining the first power generation prediction value and the second power generation prediction value according to a predetermined second combination ratio (e.g., 5:5), plus the PCS capacity of the ESS connected to the renewable energy generator.

[0122] The ratio in which the second predicted power generation value is reflected in the second combination ratio (e.g., 5) may be greater than the ratio in which the second predicted power generation value is reflected in the first combination ratio (e.g., 3). The first combination ratio and the second combination ratio may be set differently depending on the embodiment.

[0123] The first overbid capacity or the second overbid capacity may be a value greater than the first power generation forecast value.

[0124] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as a predetermined third overbid capacity and record the bid price per bidding section of the first bidding section as a lower limit price and record the supply capacity per bidding section of the second bidding section as a predetermined fourth overbid capacity and record the bid price per bidding section of the second bidding section as an upper limit price, if the trading time is included in the expected time for output control occurrence and the first generation amount predicted value is greater than or equal to a predetermined standard capacity and the trading time is not included in the ESS discharge time.

[0125] In one embodiment, a predetermined third overbid capacity may be a value calculated by combining a first power generation prediction value and a second power generation prediction value according to a predetermined first combination ratio (e.g., 7:3). In one embodiment, a predetermined fourth overbid capacity may be a value calculated by combining a first power generation prediction value and a second power generation prediction value according to a predetermined second combination ratio (e.g., 5:5).

[0126] The ratio in which the second predicted power generation value is reflected in the second combination ratio (e.g., 5) may be greater than the ratio in which the second predicted power generation value is reflected in the first combination ratio (e.g., 3). The first combination ratio and the second combination ratio may be set differently depending on the embodiment.

[0127] The third overbid capacity or the fourth overbid capacity may be a value greater than the first predicted power generation value.

[0128] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as a predetermined third overbid capacity and record the bid price per bidding section of the first bidding section as a lower limit price and record the supply capacity per bidding section of the second bidding section as a predetermined fourth overbid capacity and record the bid price per bidding section of the second bidding section as an upper limit price, if the trading time is included in the expected time for output control occurrence and the first generation amount predicted value is greater than or equal to a predetermined standard capacity and the trading time is not included in the ESS discharge time.

[0129] In one embodiment, when generating a pre-change bid, the power trading management device (1) may, if the trading time is included in the expected time for output control occurrence and the first generation amount prediction value is less than a predetermined standard capacity and the trading time is included in the ESS discharge time, record the supplyable capacity per bidding section of the first bidding section as a predetermined first overbid capacity, record the bid price per bidding section of the first bidding section as a lower limit price, record the supplyable capacity per bidding section of the second bidding section as a predetermined second overbid capacity, and record the bid price per bidding section of the second bidding section as an upper limit price.

[0130] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the reference capacity and record the bid price per bidding section of the first bidding section as the lower limit price and record the supply capacity per bidding section of the second bidding section as the reference capacity and record the bid price per bidding section of the second bidding section as the upper limit price, if the trading time is included in the expected time for output control occurrence and the first generation amount predicted value is less than the predetermined reference capacity and the trading time is not included in the ESS discharge time.

[0131] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined first overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is greater than or equal to the predetermined standard capacity, and the trading time is included in the ESS discharge time.

[0132] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined third overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is greater than or equal to the predetermined standard capacity, and the trading time is not included in the ESS discharge time.

[0133] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined first overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is less than the predetermined standard capacity, and the trading time is included in the ESS discharge time.

[0134] In one embodiment, when generating a pre-change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the standard capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is less than the predetermined standard capacity, and the trading time is not included in the ESS discharge time.

[0135] When a pre-change bid is generated, the power trading management device (1) can transmit the pre-change bid to the power exchange server (2) during a predetermined pre-change bid period (A2).

[0136] In one embodiment, a predetermined pre-change bidding period (A2) may be set based on the initial bid closing time (B1) and the first bid closing time (B3) of the transaction date. For example, the pre-change bidding period (A2) may be determined between the initial bid closing time (11:00 a.m. on May 31) and one hour before the first bid closing time of the transaction date (10:45 p.m. on May 31). As another example, the pre-change bidding period (A2) may be determined to be from 3:00 p.m. to 4:30 p.m. on the day before the transaction date (e.g., May 31).

[0137] In one embodiment, the power trading management device (1) may transmit a number of pre-change bids to the power exchange server (2) during a predetermined pre-change bidding period (A2). The power exchange server (2) may recognize the pre-change bid that is finally submitted among the number of pre-change bids as the final pre-change bid submitted by the power trading management device (1).

[0138] As described below, when a real-time change bid is conducted one day prior to or on the trading day, a problem may occur in the network between the power trading management device (1) and the power exchange server (2), or a problem may occur in either the power trading management device (1) or the power exchange server (2), so the power exchange server (2) may not be able to receive the real-time change bid. Consequently, there is a possibility that the renewable energy power plant (or renewable energy power generation business operator) may not obtain the desired profit, suffer a loss, or receive a power control order from the power exchange.

[0139] However, as described above, if a pre-change bid is transmitted to the power exchange server (2) during the pre-change bidding period, even if the power exchange server (2) cannot receive the real-time change bid due to the aforementioned problems occurring during the real-time change bidding process, a bid based on the pre-change bid can be executed, thereby minimizing losses and increasing profits for the renewable energy power plant (or renewable energy power generation business operator).

[0140] In addition, if a pre-change bid is carried out based on the aforementioned pre-change bid document, the supplyable capacity for each bid section is set to the first overbid capacity to the fourth overbid capacity, thereby allowing the winning bid capacity to be determined as a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value). As described above, if the actual generation of the renewable energy power plant is smaller than the winning bid capacity, no imbalance penalty occurs, so the loss of the renewable energy power plant (or renewable energy power generation business operator) due to the imbalance penalty can be minimized.

[0141] In addition, when a pre-change bid is executed based on the aforementioned pre-change bid document, the bid price of the first bid section is set to a lower limit and the bid price of the second bid section is set to an upper limit during the trading time period in which output control is expected to occur.

[0142] Therefore, in the first bidding section, by securing the winning capacity at a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value), it is possible to minimize losses due to the imbalance penalty while simultaneously maximizing profits from power supply and REC sales.

[0143] In addition, in the second bidding section, which is subject to output control, the probability of not winning the bid can be increased to minimize losses caused by output control and imbalance penalties, and there is the advantage that the bid price can be freely set to a value between the upper and lower limits during the real-time change bidding process.

[0144] In addition, when a pre-change bid is executed based on the aforementioned pre-change bid document, the supply capacity for each bid section is set as the first overbid capacity, the third overbid capacity, or the standard capacity during trading hours when output control is not expected to occur, and the bid price of the first bid section for all trading hours is set as the upper limit. Statistically speaking, during trading hours when output control is not expected to occur, the real-time SMP is mostly determined to be higher than the upper limit (e.g., 0 won). Therefore, by receiving the winning capacity at a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value), losses due to imbalance penalties can be minimized, while profits from power supply and REC sales can be maximized.

[0145] Next, the power trading management device (1) can generate a real-time change bid using the first power generation amount prediction value and the second power generation amount prediction value.

[0146] In one embodiment, when generating a real-time change bid, the power trading management device (1) can determine whether each trading time is included in the output control occurrence time (e.g., from 7 a.m. to 7 p.m.), which is the time when output control is expected to occur, or in the output control non-occurrence time (e.g., from 7 p.m. to 7 a.m.), which is the time when output control is expected not to occur. The output control occurrence time and the output control non-occurrence time may be set differently depending on the embodiment.

[0147] Additionally, in one embodiment, when generating a real-time change bid, the power trading management device (1) can determine whether each trading time falls within the discharge time of the ESS connected to the renewable energy power plant (e.g., from 11 a.m. to noon or from 5 p.m. to 6 p.m.). The ESS discharge time may be set differently depending on the embodiment.

[0148] In one embodiment, the real-time change bid may include the supplyable capacity and bid price for each bid section of the first bid section and the supplyable capacity and bid price for each bid section of the second bid section for the transaction time included in the expected time of output control occurrence, and may include the supplyable capacity and bid price for each bid section of the first bid section for the transaction time included in the expected time of non-occurrence of output control.

[0149] In one embodiment, the reference capacity may be set based on the installed capacity of the renewable energy power plant. For example, the reference capacity may be set to the installed capacity of the renewable energy power plant multiplied by 0.12. This is just one example, and the reference capacity may vary depending on the embodiment.

[0150] In one embodiment, when generating a real-time change bid, the power trading management device (1) may, if the trading time is included in the expected time for output control occurrence and the first generation amount prediction value is greater than or equal to a predetermined standard capacity and the trading time is included in the ESS discharge time, record the supplyable capacity per bidding section of the first bidding section as a predetermined first overbid capacity, record the bid price per bidding section of the first bidding section as a lower limit price, record the supplyable capacity per bidding section of the second bidding section as a predetermined second overbid capacity, and record the bid price per bidding section of the second bidding section as a guaranteed bid price determined based on the SMP of the previous day. In one embodiment, if the guaranteed bid price is less than or equal to the lower limit price, the bid price per bidding section of the second bidding section may be set to a value obtained by adding 1 to the lower limit price.

[0151] In one embodiment, the bid guaranteed price may be the value obtained by subtracting a predetermined correction value from the SMP of the previous day. For example, the correction value may be set to the maximum value between the SMP of the recent month or the SMP of the previous month of a thermal power plant (e.g., heavy oil, LNG, or coal power plant). This is merely one example, and the correction value may be set differently depending on the embodiment. The correction value may be positive.

[0152] The one-day advance SMP determined by the power exchange can be viewed as a forecast of the real-time SMP. However, there may be cases where the real-time SMP is determined to be negative after the one-day advance SMP is determined to be positive. In such cases, if the bid price is set to the one-day advance SMP, there is a possibility of bid failure. Therefore, the bid guarantee price is set by subtracting a predetermined correction value from the one-day advance SMP. Consequently, the probability of failing to win the bid in the second bidding period may be reduced.

[0153] In one embodiment, when generating a real-time change bid, the power trading management device (1) may, if the trading time is included in the expected time for output control occurrence and the first generation amount prediction value is greater than or equal to a predetermined standard capacity and the trading time is not included in the ESS discharge time, record the supplyable capacity per bidding section of the first bidding section as a predetermined third overbid capacity, record the bid price per bidding section of the first bidding section as a lower limit price, record the supplyable capacity per bidding section of the second bidding section as a predetermined fourth overbid capacity, and record the bid price per bidding section of the second bidding section as a guaranteed bid price. In one embodiment, if the guaranteed bid price is less than or equal to the lower limit price, the bid price per bidding section of the second bidding section may be set to a value obtained by adding 1 to the lower limit price.

[0154] In one embodiment, when generating a real-time change bid, the power trading management device (1) may, if the trading time is included in the expected time for output control occurrence and the first generation amount prediction value is less than a predetermined standard capacity and the trading time is included in the ESS discharge time, record the supplyable capacity per bidding section of the first bidding section as a predetermined first overbid capacity, record the bid price per bidding section of the first bidding section as a lower limit price, record the supplyable capacity per bidding section of the second bidding section as a predetermined second overbid capacity, and record the bid price per bidding section of the second bidding section as an upper limit price.

[0155] In one embodiment, when generating a real-time change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the reference capacity and record the bid price per bidding section of the first bidding section as the lower limit price and record the supply capacity per bidding section of the second bidding section as the reference capacity and record the bid price per bidding section of the second bidding section as the upper limit price, if the trading time is included in the expected time for output control occurrence and the first generation amount predicted value is less than the predetermined reference capacity and the trading time is not included in the ESS discharge time.

[0156] In one embodiment, when generating a real-time change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined first overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is greater than or equal to the predetermined standard capacity, and the trading time is included in the ESS discharge time.

[0157] In one embodiment, when generating a real-time change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined third overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is greater than or equal to the predetermined standard capacity, and the trading time is not included in the ESS discharge time.

[0158] In one embodiment, when generating a real-time change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the predetermined first overbid capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is less than the predetermined standard capacity, and the trading time is included in the ESS discharge time.

[0159] In one embodiment, when generating a real-time change bid, the power trading management device (1) may record the supply capacity per bidding section of the first bidding section as the reference capacity and record the bid price per bidding section of the first bidding section as the upper limit price if the trading time is included in the expected time for no output control to occur, the first generation amount prediction value is less than the predetermined reference capacity, and the trading time is not included in the ESS discharge time.

[0160] When a real-time change bid is generated, the power trading management device (1) can transmit the real-time change bid to the power exchange server (2) during a predetermined real-time change bid period (A3).

[0161] In one embodiment, a predetermined real-time change bidding period (A3) may be set based on each transaction time. For example, the real-time change bidding period (A3) for each transaction time may be set up to 75 minutes before the start time of each transaction time. For example, real-time change bidding for transaction time 1 (0:00 AM to 1:00 AM) of a transaction target date (e.g., June 1) may be possible until 22:45 PM on the day before the transaction target date (e.g., May 31).

[0162] In one embodiment, the power trading management device (1) may transmit a number of pre-change bids to the power exchange server (2) during a predetermined pre-change bidding period. The power exchange server (2) may recognize the pre-change bid that is finally submitted among the number of pre-change bids as the final pre-change bid submitted by the power trading management device (1).

[0163] When a real-time change bid is performed based on the aforementioned real-time change bid document, the supplyable capacity for each bid section is set to the first overbid capacity or the fourth overbid capacity, thereby allowing the winning bid capacity to be determined as a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value). As described above, if the actual generation of the renewable energy power plant is smaller than the winning bid capacity, no imbalance penalty occurs, so the loss of the renewable energy power plant (or renewable energy power generation business operator) due to the imbalance penalty can be minimized.

[0164] In addition, when a real-time change bid is executed based on the aforementioned real-time change bid document, the bid price of the first bid section is set to a lower limit during the trading time period in which output control is expected to occur.

[0165] Therefore, in the first bidding section, by securing the winning capacity at a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value), it is possible to minimize losses due to the imbalance penalty while simultaneously maximizing profits from power supply and REC sales.

[0166] Furthermore, when a real-time change bid is executed based on the aforementioned real-time change bid document, the bid price of the second bidding interval is set as the guaranteed bid price during the trading timeframe where output control is expected to occur. Consequently, more stable profit generation becomes possible by increasing the probability of winning the bid in the second bidding interval.

[0167] In addition, when a pre-change bid is executed based on the aforementioned pre-change bid document, the supply capacity for each bid section is set as the first overbid capacity, the third overbid capacity, or the standard capacity during trading hours when output control is not expected to occur, and the bid price of the first bid section for all trading hours is set as the upper limit. Statistically speaking, during trading hours when output control is not expected to occur, the real-time SMP is mostly determined to be higher than the upper limit (e.g., 0 won). Therefore, by receiving the winning capacity at a value greater than the accurate predicted generation value of the renewable energy power plant (e.g., the first predicted generation value), losses due to imbalance penalties can be minimized, while profits from power supply and REC sales can be maximized.
