[0081] Among them, E user1 For user benefit, the first set value may be a preset value. In the embodiment of the present invention, the first set value may be zero.

[0082] Meeting the above task execution conditions can ensure that the task will be executed only when the user benefits from demand response.

[0083] 5. Transaction execution and settlement:

[0084] User response quantity: Q user1 (the actual response point force in MW);

[0085] User benefits: E user1 (the benefits that users gain from demand response);

[0086] User revenue calculation formula:

[0087] E user1 =Q user1 ×P response -Q user1 ×P trigger ;

[0117] Optionally, the target field value corresponding to the electricity spot transaction settlement type is determined according to the predicted electricity value attribute value, predicted load, actual electricity load and actual electricity value attribute value corresponding to the transaction time to be settled, including:

[0118] The difference between the actual power load and the predicted load corresponding to the transaction time to be settled is determined as the load prediction error corresponding to the transaction time to be settled;

[0119] The difference between the actual electric quantity value attribute value and the predicted electric quantity value attribute value corresponding to the transaction time to be settled is determined as the prediction error of the electric quantity value attribute value corresponding to the transaction time to be settled;

[0121] Determine the amount of electricity sold according to the electricity value attribute value prediction error, the second adjustment coefficient and the predicted load;

[0122] If the purchased electricity is greater than zero and the sold electricity is zero, the target field value corresponding to the electricity spot transaction settlement type is determined according to the purchased electricity, the actual electricity value attribute value and the predicted electricity value attribute value;

[0123] If the purchased electricity amount is zero and the sold electricity amount is greater than zero, the target field value corresponding to the electricity spot transaction settlement type is determined according to the sold electricity amount, the actual electricity value attribute value and the predicted electricity value attribute value.

[0124] In a specific example, if the target task type carried by the virtual power plant task execution request is a power spot transaction settlement type, the virtual power plant task execution method includes the following steps:

[0125] 1. Forecast load:

[0126] Forecast load: L pred (forecasted load value in MW);

[0127] Load forecast error: E load (the difference between actual load and predicted load);

[0128] 2. Predict the value of the power value attribute:

[0129] Predicted power value attribute value: P pred (the predicted value of the electricity value attribute, in $ / MWh);

[0130] Electricity value attribute value prediction error: E price (the difference between the actual power value attribute value and the predicted power value attribute value);

[0131] 3. Trading position management

[0132] Purchase quantity: B position (The amount of electricity planned to be purchased, in MWh);

[0133] Selling power: S position (Amount of electricity planned to be sold, in MWh);

[0134] The amount of electricity purchased refers to the need to purchase additional electricity in the real-time trading market on the trading day, based on the amount of electricity purchased in the previous day's transaction, because the actual electricity load on the trading day is higher than the previous day's forecast value.

[0135] Selling electricity means that, based on the electricity purchased in the previous transaction, due to the actual electricity load on the trading day being lower than the previous forecast value, part of the purchased electricity needs to be sold in the real-time trading market on the trading day.

[0136] 4. Smart contract deployment:

[0137] Transaction income = (sell position - buy position) * (actual power value attribute value - predicted power value attribute value) > the third set value;

[0138] The third set value may be the same as or different from the first set value and the second set value, and this is not limited in the embodiment of the present invention.

[0139] It should be noted that if the sell position is greater than zero, the buy position is zero, and if the buy position is greater than zero, the sell position is zero.

[0140] 5. Transaction execution and settlement:

[0141] Transaction income: R trade (Profit from the transaction, in $)

[0142] Transaction cost: C trade (cost of the transaction, in $);

[0143] Load forecast error calculation formula:

[0144] E load =L actual -L pred ;

[0145] Among them, L actual The actual power load.

[0146] The calculation formula of the prediction error of the electric quantity value attribute value is:

[0147] E price =P actual -P pred ;

[0148] Among them, P actual It is the actual power value attribute value.

[0149] Buying electricity calculation formula:

[0150] B position =L pred +k load ×E load ;

[0151] Among them, k load is the first adjustment coefficient, which is used to adjust the purchased electricity according to the load forecast error. It should be noted that if the load forecast error shows that the actual load will be higher than the predicted load, it may be necessary to increase the purchased electricity to ensure supply.

[0152] Selling power calculation formula:

[0153] S position =L pred -k price ×E price ;

[0154] Among them, k priceis the second adjustment coefficient, which is used to adjust the sold electricity according to the prediction error of the electricity value attribute value. It should be noted that if the prediction error of the electricity value attribute value shows that the actual electricity value attribute value is higher than the predicted electricity value attribute value, then it may be necessary to increase the sold electricity to obtain higher profits.

[0155] In another specific example, Figure 2 As shown, the virtual power plant task provided by the embodiment of the present invention can be power trading. Power trading is to use smart contracts to realize automatic transactions between virtual power plants and power markets. Power trading includes: demand response, ancillary services and power spot trading settlement. The virtual power plant blockchain smart contract constructed by the embodiment of the present invention is different from the transaction blockchain dominated by the power trading center. On the basis of saving the transaction link data, it is equipped with the existing load forecasting, predicted electricity value attribute value, transaction position management, user portrait and other functions of the virtual power plant platform. According to various actual and predicted data on the chain, the conditions trigger the automatic execution of the set transaction program, thereby ensuring the optimal economy on the basis of transaction execution. Through the smart contract equipped with the existing user portrait and package recommendation algorithm of the virtual power plant platform, the intelligent management of tasks in the division of transaction benefits between the virtual power plant and the user is realized, reducing disputes and controversies.

[0156] S140: If the smart contract corresponding to the target transaction type is called and it is determined that the target field value corresponding to the target task type meets the task execution condition, the task is executed to obtain the task execution result.

[0157] The task execution result includes any one of: a demand response execution result, an auxiliary service execution result and a power spot transaction settlement result.
