As of October 2023, the total installed capacity of wind, light and hydropower will reach 1.36 billion kilowatts, accounting for 48.4% of the total installed capacity in the country. It is estimated that by 2030, non-fossil energy will account for about 25% of primary energy consumption. With the increase in new energy construction, promoting the consumption of new energy has become a top priority.

It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0032] Embodiment 1: See also Figure 1 , the optimal clearing method of bilateral transactions without network constraints based on new energy consumption includes the following steps: S1, obtain the planned value, forecast value and section limit value of the new energy market, compare the forecast value with the section limit value, and obtain the market bidding space curve based on the comparison result and combining the forecast value with the planned value.

[0035] S4, based on the optimized clearing model and constraints, combined with the current buyer quantity and price information and seller quantity and price information, the optimized clearing model is solved by transaction pair matching to obtain the optimized clearing result of bilateral transactions.

[0036] Embodiment 2: See also Figure 2 , a bilateral transaction optimization clearing system without network constraints based on new energy consumption, including: The data comparison module is used to obtain the planned value, forecast value and section limit value of the new energy market, compare the forecast value with the section limit value, and obtain the market bidding space curve based on the comparison result and the forecast value and the planned value; A data acquisition module is used to obtain buyer quantity and price information and seller quantity and price information; Model building module, used to build an optimized clearing model and the constraints of the optimized clearing model based on the buyer's quantity and price information, the seller's quantity and price information and the market bidding space curve; The model output module is used to solve the optimized clearing model based on the optimized clearing model and constraints, combined with the current buyer quantity and price information and seller quantity and price information, using the transaction pair matching method to obtain the optimized clearing result of bilateral transactions.

[0037] Embodiment 3: See also Figure 3 , the optimal clearing method of bilateral transactions without network constraints based on new energy consumption includes the following steps: Step 1: Obtain the planned value and forecast value of the new energy market, calculate the current new energy consumption situation through the planned value and forecast value of the new energy station, determine whether the market needs to be opened, and compare the forecast value with the section limit value. If the comparison result is that the forecast value is greater than the section limit value, obtain the market bidding space curve through the difference between the forecast value and the planned value.

[0038] Step 2: The market operating organization (usually the dispatching center and the trading center) announces the market opening information such as the market bidding space curve on the bidding day on the operation day.

[0039] Step three, obtain the buyer's quantity and price information and the seller's quantity and price information.

[0040] Step 4: Based on the buyer's quantity and price information and the seller's quantity and price information, combined with the market bidding space curve, construct an optimized clearing model and the constraints corresponding to the optimized clearing model. The specific method is as follows: The first step is to consider the maximization of social welfare of new energy consumption as the clearing optimization goal:

[0041] in, For social welfare, t Total electricity purchase cost during the period; for t The total electricity sales cost during the period, β is the penalty factor. for t Time Buyer j No. n The transaction power corresponding to the segment quotation; for t Time Buyer j No. n Segment quotation price; for t Time period new energy power plant i No. m The transaction power corresponding to the segment quotation; for t Time period new energy power plant i No. m Segment quotation price; T It is a collection of trading sessions; I Assemble for new energy power plants; M i For new energy power plants i The quotation segment collection of J Aggregate for the buyer; N j For the buyer j A collection of quote segments.

[0042] The following are the explanations for the above formula: 1) Buyer cost expression.

[0043] The buyer's fee expression is as follows:

[0044] In the formula: represents N j Total number of buyer's quotes, Indicates the buyer j The report n The energy price corresponding to each output range.

[0045] 2) Seller cost expression.

[0046] The seller's fee expression is as follows:

[0047] In the formula: represents M i The total number of price segments of the seller's offer, Indicates the seller i The report m The energy price corresponding to each output range.

[0048] 3) Expression of new energy consumption

[0049] Where: M i Represents new energy power plant i Total number of quotation segments, for t Time period new energy power plant i Transaction power, Indicates that new energy power plants are in the period t No. m The winning bid electricity in the output range.

[0050] The social welfare mentioned in the optimization goal refers to the income generated by the total cost of electricity purchased by all buyers minus the total cost of electricity sold by sellers and the transmission cost. This optimization goal is based on the declared electricity price and declared electricity of the buyer and seller, and takes the transaction electricity as the decision variable to obtain the transaction electricity under the maximum social benefit goal.

[0051] The second step is constraints: 1) Constraints on purchased electricity

[0052] Where: N j Indicates the buyer j Total number of quotation segments; for t Time period new energy power plant i The intraday planning value of for t Time Buyer j No. n The transaction power corresponding to the segment quotation; for t Time Buyer j No. n Section declaration of electricity.

[0053] 2) Constraints on electricity sales

[0054] Where: for t Time period new energy power plant i No. m Section declaration of electricity.

[0055] 3) Power generation capacity constraints

[0056] Where: , , for t Time period new energy power planti The intraday planning value of for t Time period new energy power plant i The predicted value of for t Time period new energy power plant i Transaction power.

[0057] 4) Climbing constraints

[0058]

[0059] in, , , To improve the ramp-up capability of new energy power plants, Improve the climbing capacity of new energy power plants.

[0060] 5) Constraints on the balance of buying and selling electricity Because the transaction path capacity constraint is not considered, it is assumed that there are buying point nodes and new energy power plant virtual paths, I is the set of new energy power plants, J is a set of buyers, a virtual trading network is formed by doing Cartesian product between new energy power plants and buyers, and H is a set of trading paths.

[0061]

[0062]

[0063]

[0064] It is the relationship matrix between transaction paths and new energy power plants; For transaction path h With new energy power plants i The relationship factor between For transaction path h A collection of new energy power plants; for t Session Trading Path h Electricity transaction at the sending end; H A collection of transaction paths.

[0065]

[0066]

[0067]

[0068] It is the transaction path and buyer relationship matrix; For transaction pathh With the buyer j The relationship factor between For transaction path h Buyer collection.

[0069] Step 5. Through the above expression, combined with the current buyer quantity and price information and seller quantity and price information, the optimized clearing model is solved by using transaction pair matching to obtain the bilateral transaction optimized clearing result.

[0070] Step six: The optimized clearing results of bilateral transactions solved by the model are released to the buyer and seller market entities after security verification.

[0071] Embodiment 4: The specific method of the optimal clearing method of bilateral transactions without network constraints based on new energy consumption is as follows: Assumptions and initial data: 1. Time period (T): Assuming one day's trading is considered, the time period is 24 hours (T=24).

[0072] 2. Buyer (J): Assume there are two buyers J1 and J2, each with a different quantity and price quotation segment.

[0073] 3. Seller (I): Assume there are two sellers I1 and I2, representing two new energy power plants respectively.

[0074] 4. Bidding space curve: S1: Obtain the planned value and predicted value, and calculate the bidding space; The section limit of new energy power plants I1 and I2 is 750MW. The planned power generation capacity of the new energy power plant I1 is 400MW and the forecast value is 600MW.

[0075] The planned power generation capacity of the new energy power plant I2 is 350MW, and the predicted value is 550MW.

[0076] The comparison between the planned value and the section limit is as follows: (I1+I2) predicted value>section limit, the market needs to be opened.

[0077] Therefore, the market bidding space is: Buyer I1: 200MW, Buyer I2: 200MW.

[0078] S2: Obtain quantity and price information of buyers and sellers; Buyer J1: The first paragraph of quotation: Power: (0,50] Price: 0.1 yuan / MW.

[0079] The second quotation: Power: (50,150] Price: 0.2 yuan / MW.

[0080] The third section of the quotation: Power: (150,200] Price: 0.4 yuan / MW.

[0081] Buyer J2: The first paragraph of the quotation: Power: (0,50] Price: 0.2 yuan / MW.

[0082] The second quotation: Power: (50,150] Price: 0.3 yuan / MW.

[0083] The third section of the quotation: Power: (150,200] Price: 0.4 yuan / MW.

[0084] Seller I1: The first paragraph of the quotation: Power: (0,100] Price: 0.5 yuan / MW.

[0085] The second quotation: Power: (100,200] Price: 0.35 yuan / MW.

[0086] The third section of quotation: Power: (200,300] Price: 0.1 yuan / MW.

[0087] Seller I2: The first paragraph of the quotation: Power: (0,50] Price: 0.6 yuan / MW.

[0088] The second quotation: Power: (50,100] Price: 0.3 yuan / MW.

[0089] The third section of the quotation: Power: (100,300] Price: 0.2 yuan / MW.

[0090] S3: Construct an optimal clearing model and its constraints; The optimization goal is to maximize social welfare:

[0091] Assume the penalty factor = 0.01.

[0092] S4: Solve the optimized clearing model by matching trading pairs; Based on the quotation information and bidding curves of buyers and sellers, an optimization problem is constructed and solved.

[0093] When section constraints are not considered, Buyer J1: 150MW; Buyer J2: 150MW Seller I1: 200MW; Seller I2: 100MW Marginal electricity price: 0.4 yuan / MW.

[0094] S5: Check and publish the optimization and clearing results; The solved results are security-checked to ensure that the transaction meets the requirements for safe and stable operation of the power system, and then the results are released to buyers and sellers.

[0095] Final result: Buyer J1 purchases 150MW of electricity, and buyer J2 purchases 150MW of electricity, at a price of 0.4 yuan / MW.

[0096] Seller I1 sold 200MW of electricity and seller I2 sold 100MW of electricity at a price of 0.4 yuan / MW.

[0097] The above process demonstrates a simplified specific solution process and obtains the optimal clearing result of bilateral transactions.
