[0029] Embodiment 1

[0030] Figure 1 FIG. 6 is a flowchart of a method for determining a hydropower trading strategy provided by Embodiment 1 of the present invention. This embodiment is applicable to situations where price prediction and trading strategy formulation are required in hydropower trading. The method can be executed by a hydropower trading strategy determination device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device with data processing capabilities. As Figure 1 shown, the method includes:

[0031] S110. Determine at least one historical power information corresponding to the target area and a historical hydropower price group corresponding to each historical power information.

[0032] The power information is information within the target area that affects the electricity price and the degree of influence is greater than a preset degree; the historical power information is the power information of the target area on a historical day; the historical days corresponding to each historical power information are different; the hydropower price group includes medium - long - term price, day - ahead price, and spot price.

[0033] Since the power generation capacity of hydropower units is affected by natural conditions (such as water resource flow rate, etc.), how to make an optimal trading strategy among multiple electricity market transactions (such as medium - long - term, day - ahead, real - time markets) has become a key issue in improving electricity efficiency.

[0034] When predicting hydropower prices in the prior art, simply relying on historical data for prediction often leads to large deviations, making it difficult to adapt to the dynamic changes in the short - term market, and mostly predicting the price situation of a single market, failing to comprehensively predict medium - long - term, day - ahead, and real - time prices.

[0035] When predicting the predicted hydropower price group on the prediction day in this application, it is necessary to first obtain at least one historical power information corresponding to the target area and a historical hydropower price group corresponding to each historical power information.

[0036] For the selection of power information, information within the target area that affects the electricity price and the degree of influence is greater than a preset degree will be selected, including but not limited to the electricity market bidding space, electricity market clearing price, and target area electricity load.

[0037] Among them, the electricity market bidding space can be the price range in which buyers and sellers reach a transaction through bidding and asking prices during the electricity market transaction process. The lower limit of this range is usually the lowest price acceptable to the seller, and the upper limit is the highest price willing to be paid by the buyer.

[0038] The clearing price of the electricity market can be the bid price of the power generation enterprise that meets the last unit of electricity demand.

[0039] The power load of the target area can refer to the total electric power consumed by all users in the target area.

[0040] This enables, when predicting the electricity price on the prediction day, to avoid simply relying on the historical hydropower electricity price group for prediction and ignoring the changes in the data that affect the hydropower price, thereby ensuring the accuracy of the predicted hydropower electricity price group corresponding to the prediction day as much as possible.

[0041] Among them, the prediction day is the date when the target area needs to predict the electricity price.

[0042] S120. Determine the predicted power information of the target area on the prediction day.

[0043] Since the predicted power information of the target area on the prediction day will be announced before the actual value of the predicted hydropower electricity price group on the prediction day is announced, by using the predicted power information of the target area on the prediction day and the historical power information of the target area in previous periods, it is possible to predict the predicted hydropower electricity price group on the prediction day before the predicted hydropower electricity price group on the prediction day is announced. Therefore, it is necessary to determine the predicted power information of the target area on the prediction day on the prediction day.

[0044] S130. Determine the predicted hydropower electricity price group of the target area on the prediction day according to at least one historical power information, the historical hydropower electricity price groups corresponding to each historical power information, and the predicted power information.

[0045] After obtaining at least one historical power information and the predicted power information on the prediction day, at this time, the predicted power information and each historical power information can be compared to determine the historical day that is most similar to the prediction day in terms of power information, and based on the historical hydropower electricity price group corresponding to this historical day, determine the predicted hydropower electricity price group of the target area on the prediction day.

[0046] Exemplarily, when the prediction day is Day A, the historical days include Day B and Day C. At this time, the similarity between the predicted power information corresponding to Day A and the historical power information corresponding to Day B and Day C is 90% and 80% respectively. At this time, it can be determined that the predicted power information of Day A is closer to the historical power information of Day B. At this time, the predicted hydropower electricity price group of Day A can be determined through the historical hydropower electricity price group of Day B.

[0047] In an alternative solution, determining the predicted hydropower electricity price group of the target area on the prediction day according to at least one historical power information, the historical hydropower electricity price groups corresponding to each historical power information, and the predicted power information may include steps A1 - A3:

[0048] Step A1: Based on the similarity algorithm, determine the similarity between each historical power information and the predicted power information, and obtain the information similarity corresponding to each historical power information.

[0049] Step A2: Determine the historical hydropower price group corresponding to the historical power information with the maximum information similarity as the reference hydropower price group of the target area on the prediction day.

[0050] Step A3: Based on the reference hydropower price group and the information similarity of the historical power information corresponding to the reference hydropower price group, determine the predicted hydropower price group of the target area on the prediction day.

[0051] When determining the similarity between each historical power information and the predicted power information, to ensure the accuracy of the determination result, a similarity algorithm can be used to judge the similarity between each historical power information and the predicted power information, so as to obtain the information similarity corresponding to each historical power information.

[0052] After obtaining the information similarity corresponding to each historical power information, the historical hydropower price group corresponding to the historical power information with the maximum information similarity can be determined as the reference hydropower price group of the target area on the prediction day, and based on the reference hydropower price group, the predicted hydropower price group of the target area on the prediction day can be determined.

[0053] Optionally, the similarity algorithm is a cosine similarity algorithm or an Euclidean distance similarity algorithm.

[0054] S140: Generate a hydropower trading strategy based on the predicted hydropower price group.

[0055] After obtaining the predicted hydropower price group, that is, the medium - long - term price, day - ahead price, and spot price corresponding to the target area on the prediction day, corresponding hydropower trading strategies can be formulated according to the differences in the medium - long - term price, day - ahead price, and spot price, so as to reduce losses or increase profits when selling hydropower, and then optimize the market performance of hydropower generating units.

[0056] According to the technical solution of the embodiment of the present invention, by determining at least one historical power information corresponding to the target area and the historical hydropower price group corresponding to each historical power information; determining the predicted power information of the target area on the prediction day; and determining the predicted hydropower price group of the target area on the prediction day according to at least one historical power information, the historical hydropower price group corresponding to each historical power information, and the predicted power information, an accurate prediction of the predicted hydropower price group of the target area on the prediction day is realized, and finally, based on the predicted hydropower price group, a hydropower trading strategy is generated, so as to reduce losses or increase profits when selling hydropower, and then optimize the market performance of hydropower generating units.

[0057] Embodiment Two

[0058] Figure 2 The present invention provides a flowchart of another method for determining a hydropower trading strategy. Based on the above embodiments, the present embodiment further optimizes the process of generating a hydropower trading strategy based on a predicted hydropower price group in the foregoing embodiments. The present embodiment can be combined with various alternative solutions in one or more of the above embodiments. As Figure 2 shown, the method for determining a hydropower trading strategy in this embodiment may include the following steps:

[0059] S210. Determine at least one piece of historical power information corresponding to the target area and the historical hydropower price group corresponding to each piece of historical power information.

[0060] The power information is information that affects the power price in the target area and the influence degree is greater than a preset degree; the historical power information is the power information in the target area on a historical day; the historical days corresponding to each piece of historical power information are different; the hydropower price group includes medium - long - term price, day - ahead price, and spot price; the power information at least includes the power market bidding space, the power market clearing price, and the power load in the target area.

[0061] S220. Determine the predicted power information of the target area on the predicted day.

[0062] S230. Determine the predicted hydropower price group of the target area on the predicted day according to at least one piece of historical power information, the historical hydropower price group corresponding to each piece of historical power information, and the predicted power information.

[0063] S240. Determine the medium - long - term demand power generation amount of the target area on the predicted day and the power generation capacity of the hydropower unit.

[0064] S250. If the predicted medium - long - term price is greater than the predicted day - ahead price, the predicted day - ahead price is greater than the predicted spot price, and the power generation capacity of the hydropower unit is greater than the medium - long - term demand power generation amount, then execute the first strategy.

[0065] The first strategy is to control the hydropower unit to generate electricity according to the medium - long - term demand power generation amount.

[0066] The medium - long - term demand power generation amount may be the power generation amount to be sold at the medium - long - term price determined in advance.

[0067] In the case where the predicted medium - long - term price is greater than the predicted day - ahead price and the predicted day - ahead price is greater than the predicted spot price, it can be determined that the predicted medium - long - term price is the highest on the predicted day. At this time, if the power generation capacity of the hydropower unit is greater than the medium - long - term demand power generation amount, it indicates that the hydropower unit can meet the medium - long - term demand power generation amount. At this time, the hydropower unit will be directly controlled to generate electricity according to the long - term demand power generation amount.

[0068] In an alternative solution, based on the predicted hydropower price group, a hydropower trading strategy is generated, which may include steps B1 - B2:

[0069] Step B1: Determine the medium - and long - term demand power generation in the target area on the prediction day and the power generation capacity of the hydropower units.

[0070] Step B2: If the predicted medium - and long - term price is greater than the price before the prediction day, the price before the prediction day is greater than the predicted spot price, and the power generation capacity of the hydropower units is less than the medium - and long - term demand power generation, then execute the second strategy; the second strategy is to control the hydropower units to generate electricity at full capacity and purchase electricity corresponding to the predicted spot price according to the power generation demand difference; the power generation demand difference is obtained by subtracting the power generation capacity of the hydropower units from the medium - and long - term demand power generation.

[0071] When the predicted medium - and long - term price is greater than the price before the prediction day and the price before the prediction day is greater than the predicted spot price, if the power generation capacity of the hydropower units is less than the medium - and long - term demand power generation, it indicates that only generating electricity through hydropower units cannot meet the medium - and long - term demand power generation. At this time, the electricity can be purchased at the predicted spot price with the lowest price to make up for the difference in long - term demand power generation.

[0072] In an alternative solution, based on the predicted hydropower price group, a hydropower trading strategy is generated, which may include steps C1 - C2:

[0073] Step C1: Determine the medium - and long - term demand power generation in the target area on the prediction day and the power generation capacity of the hydropower units.

[0074] Step C2: If the predicted medium - and long - term price is less than the price before the prediction day, the price before the prediction day is less than the predicted spot price, and the power generation capacity of the hydropower units is greater than the medium - and long - term demand power generation, then execute the third strategy; the third strategy is to control the hydropower units to generate electricity at full capacity and sell the excess power generation according to the predicted spot price; the excess power generation is obtained by subtracting the medium - and long - term demand power generation from the power generation produced by the hydropower units generating electricity at full capacity.

[0075] When the predicted medium - and long - term price is less than the price before the prediction day and the price before the prediction day is less than the predicted spot price, since the predicted medium - and long - term price is relatively low, when generating electricity through hydropower units to meet the medium - and long - term demand power generation, the final benefit will be relatively low. At this time, if the power generation capacity of the hydropower units is greater than the medium - and long - term demand power generation, the hydropower units can be controlled to generate electricity at full capacity to obtain excess power generation, and the excess power generation can be sold according to the predicted spot price to increase the overall income.

[0076] In an alternative solution, based on the predicted hydropower price group, a hydropower trading strategy is generated, which may include steps D1 - D2:

[0077] Step D1: Determine the medium- and long-term demand power generation of the target area on the prediction date and the power generation capacity of the hydropower units.

[0078] Step D2: If the predicted medium- and long-term price is less than the price before the prediction date, the price before the prediction date is greater than the predicted spot price, and the power generation capacity of the hydropower units is greater than the medium- and long-term demand power generation, then implement the fourth strategy; the fourth strategy is to control the hydropower units to generate electricity at full capacity and sell the excess power generation according to the price before the prediction date; the excess power generation is obtained by subtracting the medium- and long-term demand power generation from the power generation produced by the hydropower units generating electricity at full capacity.

[0079] In the case where the predicted medium- and long-term price is less than the price before the prediction date and the price before the prediction date is greater than the predicted spot price, since the predicted medium- and long-term price is low, when generating electricity through hydropower units to meet the medium- and long-term demand power generation at this time, it will lead to a low final benefit. At this time, if the power generation capacity of the hydropower units is greater than the medium- and long-term demand power generation, the hydropower units can be controlled to generate electricity at full capacity, so as to obtain excess power generation, and the excess power generation is sold according to the price before the prediction date, thereby increasing the overall income.

[0080] According to the technical solution of the embodiment of the present invention, by determining the medium- and long-term demand power generation of the target area on the prediction date and the power generation capacity of the hydropower units; if the predicted medium- and long-term price is greater than the price before the prediction date, the price before the prediction date is greater than the predicted spot price, and the power generation capacity of the hydropower units is greater than the medium- and long-term demand power generation, then implement the first strategy, thereby clarifying the specific process of generating a hydropower trading strategy based on the predicted hydropower price group and providing guidance for actual implementation.
