Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electric power dispatching, and in particular to a method, device and storage medium for adjusting monthly spot revenue of a new energy enterprise. Background Art
[0002] With the rapid development of new energy sources such as wind power and photovoltaics, how new energy power generation companies participate in electricity spot market transactions has always been a key issue in the construction of electricity marketization. In the electricity market, due to the characteristic that electricity commodities cannot be "stored on a large scale", unit electricity commodities must bear the responsibility of balance in order to reflect their accurate prices. If the power source causes an imbalance at the settlement level due to output deviation, it must bear the corresponding imbalance responsibility. In the short term, this will help promote more new energy power generation companies to participate in the electricity spot market, so that the clearing price can more truly reflect the market supply and demand relationship and the value of electricity. In the long run, it will also provide a reference for more new energy power generation companies to participate in the market mechanism design of electricity spot transactions and power supply planning decisions in the new energy field.
[0003] Due to the unpredictability of renewable energy output, as more and more new energy companies participate in electricity spot market transactions, market price volatility may further increase. The electricity market urgently needs to further improve its adaptability to a high proportion of renewable energy. At present, the electricity market's adaptability to renewable energy is still relatively lacking, and the flexibility and liquidity of medium- and long-term trading mechanisms are relatively poor. It is difficult to meet the demand for new energy transactions in areas where electricity spot markets operate.
[0004] However, the existing technology has problems such as the high volatility of spot prices due to the unpredictable output of new energy power generation enterprises participating in the electricity spot market due to their own reasons, large fluctuations in clearing results in different time periods, and the difficulty in ensuring the economic feasibility of clearing results. The uncertainty of the benefits of new energy power generation enterprises participating in the electricity spot market is relatively large, which is not conducive to the reasonable control of spot market risks and the avoidance of major adjustments in the interests of power generation and consumption. Summary of the invention

[0116] It can be understood that in the solution of this embodiment, the new energy power generation enterprise adopts a three-part settlement model: full electricity settlement of medium- and long-term contracts (including medium- and long-term contract blocking electricity charges), the deviation of electricity between the day-ahead market and the medium- and long-term market is settled according to the day-ahead market price, and the deviation of electricity between the real-time market and the day-ahead market is settled according to the real-time market price, which specifically includes:
[0117] (1) Medium- and long-term market settlement of new energy power generation enterprises:
[0118] New energy power generation enterprises calculate the full electricity charges according to the unit's inter-provincial and intra-provincial medium- and long-term contract time-of-use electricity and net contract comprehensive price. The formula is:
[0119] R 中长期合约,T =Q i省内中长期净合约,T ×P 省内中长期净合约,T
[0120] In the formula, Q i省内中长期净合约,T P is the medium- and long-term net contractual electricity volume of any unit i in the province during period T, obtained through the market-based transaction contract signed by the new energy power generation enterprise; 省内中长期净合约,T The comprehensive price of the medium- and long-term net contract of any unit in the province during the T period, which is also obtained through the market-based transaction contract signed by the new energy power generation enterprise;
[0121] (2) Day-ahead market deviation settlement for new energy power generation enterprises:
[0122] Day-ahead deviation power calculation:
[0123] Q 日前偏差i,T =Q i日前出清,T -Q i省内中长期净合约,T -Q i电网代购市场电量,T
[0124] In the formula, Q 日前偏差i,T is the day-ahead deviation power of any unit i in period T; Q i日前出清,T is the day-ahead electricity cleared by any unit i in period T, obtained through the southern regional spot electricity energy trading system; Q i电网代购市场电量,T The actual electricity purchased by any unit i in the net power grid during the T period is calculated by the total amount through the method of "determining the power generation based on the usage" and is decomposed and calculated according to the planned proportion of the unit;
[0125] According to the difference between the day-ahead market clearing electricity volume and the medium- and long-term contract electricity volume within the province, the day-ahead market deviation electricity fee is calculated based on the day-ahead market node electricity price. The formula is:
[0126] R 日前偏差,T =Σ(Q 日前偏差i,T ×P 日前,T )
[0127] In the formula, R 日前偏差,T is the day-ahead market deviation electricity price; P 日前,T The settlement electricity price of the day-ahead market during the T period at the node where the unit is located is obtained through the Southern Regional Spot Electricity Energy Trading System;
[0128] (3) Real-time market deviation settlement for new energy power generation enterprises:
[0129] Real-time deviation power calculation:
[0130] Q 实时偏差i,T =Q D,T -Q i日前出清,T
[0131] In the formula, Q实时偏差i,T is the real-time deviation power of any unit i in period T; Q D,T is the total on-grid power consumption of a market entity during the T period on the D day,
[0132] Q D,T The acquisition is as follows:
[0133] Since wind power and photovoltaic power generation companies are geographically distributed in a wide range and have uneven output, and each plant and station independently reports and quotes quantities, the collection of energy data is somewhat difficult, and the power spot market requires high data accuracy. Time-sharing transactions are different from traditional medium- and long-term transactions in the following ways:
[0134] Table 1: Comparison between time-segment trading and traditional medium- and long-term trading
[0135]
[0136] The specific time period trading decomposition formula is as follows:
[0137]
[0138] Where: Q D,T Q is the total contracted electricity volume of a market entity during the T period on the D day; Y,T , Q S,T , Q M,T , Q X,T are the total contracted electricity volume in the annual, quarterly, monthly and weekly trading periods, respectively; Y, S, M and X are the calendar days of the target period of the annual, quarterly, monthly and weekly trading period to which D day belongs, respectively;
[0139] The power generation side calculates the deviation electricity fee based on the difference between the actual on-grid electricity of the unit and the on-grid electricity cleared by the market a day ago, as well as the real-time market node electricity price. The formula is:
[0140] R 实时偏差,T =Σ(Q 实时偏差i,T ×P 实时,T )
[0141] In the formula, R 实时偏差,T is the real-time market deviation electricity price; P 实时,T The real-time market settlement price in the T period of any node where the unit is located is obtained through the Southern Region Spot Electricity Energy Trading System;
[0142] (4) Imbalanced Funding:
[0143] The imbalance funds are obtained by adding up the eight parts: the inter-regional and inter-provincial medium- and long-term contract blocking electricity charges, the inter-regional and inter-provincial imbalance funds, the provincial medium- and long-term contract blocking electricity charges, the imbalance deviation electricity charges of power generation and consumption, the market partial blocking surplus, the user deviation income transfer electricity charges, the medium- and long-term deviation income recovery on the power generation side, and the medium- and long-term deviation income recovery on the power consumption side. The specific details are as follows:
[0144] ① Inter-regional and inter-provincial medium- and long-term contracts block electricity charges:
[0145] R 跨区跨省中长期合约阻塞,T =Q 跨区跨省中长期净合约,T ×(P 日前,T -P 日前送出关口,T )
[0146] Where P 日前送出关口,T It is the electricity price at the delivery side in the T period of the day-ahead market. The data comes from the spot electricity energy trading system. 跨区跨省中长期净合约,T The net mid- and long-term contracted electricity volume across regions and provinces of any unit of a new energy power generation enterprise in the T period is obtained through the market-based transaction contract signed by the new energy power generation enterprise;
[0147] ② Unbalanced funds across regions and provinces:
[0148] Under the regional spot market environment, the imbalance funds are mainly divided into two parts: cross-regional and cross-provincial and intra-provincial, and are calculated separately. The cross-regional and cross-provincial imbalance funds refer to the imbalance funds generated by the difference between the sending-side price of the cross-provincial spot transaction and the sending-side gate price of the sending province (region). The cross-regional and cross-provincial imbalance funds are issued by the power trading center in accordance with the principle of "whoever generates, whoever is responsible; whoever benefits, whoever shares". The power trading center settles in proportion to the cross-regional and cross-provincial medium- and long-term transaction electricity (including cross-provincial priority power generation plans) undertaken by the units of the sending-end power generation enterprises, and the units of the sending-end power generation enterprises share or apportion. The other expenses issued by the power trading center except the cross-regional and cross-provincial imbalance funds are handled in accordance with the cross-regional and cross-provincial imbalance funds sharing or apportionment method. The specific formula is as follows:
[0149] R i,T =R 跨区跨省不平衡资金,T ×Q i,T / Q 跨区跨省总中长期合约,T
[0150] In the formula, R i,t The inter-regional and inter-provincial imbalance funds shared or apportioned to the generator set i; R 跨区跨省不平衡资金,t It is the inter-regional and inter-provincial imbalance funds issued by the power trading center; i,t Q is the inter-regional and inter-provincial medium- and long-term trading electricity of unit i in period T; 跨区跨省总中长期合约,t It is the sum of all inter-regional and inter-provincial market units and inter-provincial medium- and long-term contracts;
[0151] ③ Medium- and long-term contract blocking electricity charges within the province:
[0152] R 省内中长期合约阻塞,T =Q 省内中长期净合约,T ×(P 日前,T -P 日前统一,T )
[0153] Where P 日前统一,T is the unified settlement price of the day-ahead market at the node where unit i is located in period T;
[0154] ④ Electricity charges due to imbalance in power generation and consumption:
[0155] The electricity fee for the imbalance of power generation and consumption in the market is caused by the difference between the settlement power reported by the user and the clearing power of the market unit in the day before. During the trial operation of spot settlement, some business entities did not participate in the spot settlement. The electricity fee for the imbalance of power generation and consumption in the market should be deducted from the corresponding power fee. The specific formula is as follows:
[0156] R 发用电量不平衡偏差,T =[Q 用户日前申报,T -(Q 日前机组出清市场电量,T -ΣQ 电网代购市场电量实结电量,T -(Q 跨省中
[0157] 长期合约,T +Q 跨省日前偏差,T ))]×(P 日前统一结算价,T -P 实时统一结算价,T )
[0158] In the formula, Q 用户日前申报,T Q is the total electricity reported by the user at T hours the day before, after deducting the electricity converted from the winning bid capacity of the demand-side response; 日前机组出清市场电量,T Q is the total market electricity cleared by the market units directly participating in the transaction at T hours before the day; 跨省中长期合约,T Q is the medium- and long-term contractual electricity volume of Guizhou Power Grid according to the transmission category during the T period; 跨省日前偏差,T P is the day-ahead deviation of Guizhou Power Grid to the grid according to the power transmission category during the T period; 日前统一结算价,T P is the unified settlement price at the user side T hours before the day; 实时统一结算价,T It is the real-time unified settlement price at T hour on the user side;
[0159] The electricity charges for the imbalance of power generation and consumption in the market are based on the principle of "hourly statistics and monthly allocation". The electricity charges are allocated or refunded by the units with intra-provincial transactions on the power generation side and the user side according to the proportion of the monthly grid-connected power or the proportion of the monthly power consumption:
[0160] in:
[0161] When P 发电日前加权,T >P 发电实时加权,T And R 发用电量不平衡偏差,T >0, R 发用电量不平衡偏差,T Accumulated and apportioned or shared to the user side;
[0162] When P发电日前加权,T >P 发电实时加权,T And R 发用电量不平衡偏差,T When R 发用电量不平衡偏差,T Accumulated to the power generation side for allocation or sharing;
[0163] When P 发电日前加权,T <P 发电实时加权,T And R 发用电量不平衡偏差,T When R 发用电量不平衡偏差,T Accumulated and apportioned or shared to the user side;
[0164] When P 发电日前加权,T <P 发电实时加权,T And R 发用电量不平衡偏差,T >0, R 发用电量不平衡偏差,T Accumulated and allocated or shared to the power generation side.
[0165] In the above formula, P 发电日前加权,T and P 发电实时加权,T Obtained by hourly weighting based on the unit’s day-ahead and real-time market electricity consumption;
[0166] ⑤ Market partial blockage surplus:
[0167] The market surplus is equal to the difference between the energy fee paid by the user at the unified settlement point electricity price, the energy fee for cross-regional and cross-provincial three-part settlement electricity, and the energy fee charged for the corresponding market-based trading electricity of the provincial market units. Specifically, it includes the market power generation and consumption imbalance deviation fee and the market partial blocking surplus. During the trial operation of spot settlement, some business entities did not participate in spot settlement. The corresponding electricity fee should be deducted when calculating the market surplus. The specific formula is as follows:
[0168] R 市场盈余费用,T =(C 中长期合约,T +C 日前偏差,T +C 实时偏差,T +R 跨省中长期合约,T +R 跨省日前偏差,T +R 跨省实
[0169] 时偏差,T )-(R 中长期合约,T +R 日前偏差,T +R 实时偏差,T +R 跨区跨省中长期合约阻塞,T +R 省内中长期合约阻塞,T )
[0170] In the formula, C 中长期合约,T represents the medium- and long-term electricity charges of the user side during the T period, which comes from the unified power trading platform, C 日前偏差,T represents the day-ahead market deviation electricity price on the user side during period T, which comes from the unified power trading platform, C 实时偏差,T It represents the real-time market deviation electricity energy and electricity fee of the user side during the T period, which comes from the unified power trading platform; R 跨省中长期合约,TThe electricity price of the inter-provincial medium- and long-term contract for the T period provided by the power trading center; R 跨省日前偏差,T The electricity price of the inter-provincial day-ahead deviation electricity quantity during the T period provided by the power trading center; R 跨省实时偏差,T The real-time deviation electricity charges for inter-provincial electricity in the T period provided by the power trading center; the market partial blocking surplus is equal to the market surplus minus the imbalance electricity charges for power generation and consumption, which is apportioned or shared by the power generation side according to the proportion of grid-connected electricity on a monthly basis;
[0171] ⑥ User deviation benefit transfer electricity fee:
[0172] The user side real-time market time-of-use deviation electricity is post-calculated and judged. If it exceeds the allowable deviation range, the price difference between the real-time market and the day-ahead market time-of-use price outside the user's allowable deviation is transferred. The user deviation profit transfer fee is returned to the user side in monthly units according to the proportion of electricity consumption. The allowable deviation range is the actual time-of-use electricity λ0 and below. The specific formula is as follows:
[0173] When Q 申报,T >Q 用电,T ×(1+λ0), and P 实时统一,T >P 日前统一,T hour,
[0174] C=Σ[Q 申报,T -Q 用电,T ×(1+λ0)]×(P 实时统一,T -P 日前统一,T );
[0175] When Q 申报,T 用电,T ×(1-λ0), and P 实时统一,T <P 日前统一,T hour,
[0176] C=Σ[(Q 用电,T ×(1-λ0)-Q 申报,T ]×(P 日前统一,T -P 实时统一,T ).
[0177] Where C is the deviation benefit of the user to be transferred; Q 用电,T The actual electricity consumption of the user during period T, minus the renewable energy contract decomposition electricity during that period; Q 申报,T The power demand for this period reported by the market a day ago, minus the power conversion of the winning bid capacity of the demand side response during this period; P 实时统一,T P is the unified settlement point electricity price in the real-time market T period; 日前统一,T is the unified settlement point electricity price in the day-ahead market during period T; λ0 is the allowable deviation ratio of the price difference profit;
[0178] ⑦ Recovery of medium- and long-term deviation income on the power generation side:
[0179] On the basis that the medium- and long-term electricity is settled at the contract price and the spot deviation electricity is settled at the spot price, the annual and monthly medium- and long-term transaction electricity of the unit should not be less than u% of the full-month market electricity (zero when negative). Deviation electricity within the allowable negative deviation v% range will not be recovered. For the electricity outside the allowable negative deviation range, the revenue will be recovered at the kilowatt-hour recovery price on a monthly basis. The specific calculation formula is as follows:
[0180] When the electricity price at the user-side unified settlement point does not converge:
[0181] P 机组度电回收价格 =(P 机组日前市场月度加权平均综合电价 -P 月竞均价 )×h
[0182] Where P 机组度电回收价格 is the price of electricity recovery from the generating unit at the generating side, which is set to zero when it is negative; P 月竞均价 The average price of the monthly centralized competitive transaction in the current month. If it is missing, it will be replaced by the transaction price of electricity purchased by the power grid on behalf of the market. The specific price shall be subject to the trial operation implementation plan; P 机组日前市场月度加权平均综合电价 It is the value obtained by weighted calculation of all node electricity prices of the unit in the day-ahead market in the current month according to the market electricity proportion in the corresponding period; h is the deviation profit recovery adjustment coefficient;
[0183] When the electricity price at the user-side unified settlement point converges:
[0184] P 机组度电回收价格 =(P 机组回收 -P 月竞均价 )×h
[0185] in,
[0186] P 机组回收 =P 中长期 +(P 收敛前机组日前市场月度加权平均综合电价 -P 中长期 )*L T
[0187] Where P 中长期 is the weighted average price of the medium- and long-term contracts per hour on the operating day, L T is the spot price limit parameter;
[0188] When the medium- and long-term contract power - market power × (u% - v%) < 0, the medium- and long-term deviation income recovery on the power generation side = (medium- and long-term planned power - market power × (u% - v%)) × P 机组度电回收价格 ;
[0189] When the medium- and long-term contract electricity - market electricity × (u% - v%) ≥ 0, no revenue recovery will be carried out; the medium- and long-term transaction deviation revenue recovery fee on the power generation side is returned to the user side in monthly units according to the proportion of electricity consumption;
[0190] ⑧ Recovery of medium- and long-term deviation benefits on the electricity consumption side:
[0191] On the basis that the medium- and long-term electricity is settled at the contract price and the spot deviation electricity is settled at the spot price, the annual and monthly medium- and long-term transaction electricity on the user side should not be less than its actual monthly electricity consumption u%. The deviation electricity within the allowable negative deviation v% range will not be recovered. For the electricity outside the allowable negative deviation range, the revenue will be recovered at the kilowatt-hour recovery price on a monthly basis. The specific calculation formula is as follows:
[0192] P 用户度电回收价格 =(P 月竞均价 -P 日前市场月度加权平均综合电价 )×h
[0193] Where P 用户度电回收价格 is the user-side electricity recovery price, which is set to zero when it is negative; P 售电公司日前市场月度加权平均综合电价 The value is obtained by weighted calculation of the electricity prices of all unified settlement points in the day-ahead market of each power sales company (including large users in the wholesale market) within the month according to the proportion of total market electricity in the corresponding period;
[0194] When the medium- and long-term contract power - actual power consumption × (u% - v%) < 0, the medium- and long-term deviation income recovery fee on the power consumption side = (medium- and long-term planned power - actual power consumption × (u% - v%)) × P 用户度电回收价格 ; When the medium- and long-term contract power - actual power consumption × (u% - v%) ≥ 0, no revenue recovery will be carried out; in principle, the funds for the recovery of the deviation of the medium- and long-term transaction on the power consumption side will be shared by the units with intra-provincial transactions on the power generation side according to the proportion of their monthly grid-connected power;
[0195] (V) Obtain the actual on-grid electricity quantity of any unit i in the T period through the unified power trading platform and power marketing system, obtain the provincial benchmark on-grid electricity price in the T period, and obtain the benchmark income based on the actual on-grid electricity quantity of any unit i in the preset period and the provincial benchmark on-grid electricity price. The formula is as follows:
[0196] R 基准收益,T =Q 新能源上网电量,T ×P 标杆上网电价,T
[0197] In the formula, Q 新能源上网电量,T P represents the actual on-grid power of any unit i in the T period; 标杆上网电价,T Indicates the provincial benchmark on-grid electricity price during the T period, such as 0.3515 yuan / kW in Guizhou
[0198] (6) Spot income acquisition:
[0199] Through medium and long-term net contract electricity charges R 中长期合约,T , the day-ahead market deviation electricity price R 日前偏差,T , Real-time market deviation electricity price R实时偏差,T And unbalanced funds to obtain spot income C 现货 , the formula is:
[0200] C 现货 =R 中长期合约,T +R 日前偏差,T +R 实时偏差,T +Imbalanced Funds
[0201] (7) In order to reasonably control the spot market risks and avoid large fluctuations in the profits of new energy power generation enterprises, the monthly settlement electricity charges (including the allocation of imbalance funds) of the spot settlement model shall be adjusted in the form of electricity charge recovery or compensation; the spot market expenses of new energy power generation enterprises shall be calculated and judged after the fact in the form of monthly unified settlement. Taking each new energy power generation enterprise as the benchmark, the difference between the spot income of the new energy power generation enterprise and the income adjustment benchmark shall be calculated separately. The electricity charges exceeding the income adjustment benchmark ±k (k is the allowable income deviation range) shall be recovered or compensated to the power generation side on a monthly basis to maintain a smooth market transition. The calculation formula for income adjustment fee is as follows:
[0202] C 现货 -R 基准收益,T >R 基准收益,T *k, it is recovered to the power generation side;
[0203] C 调节 =C 现货 -R 基准收益,T *(1+k);
[0204] C 现货 -R 基准收益,T <R 基准收益,T *(-k), compensate the power generation side;
[0205] C 调节 =C 现货 -R 基准收益,T *(1-k);
[0206] R 基准收益,T *(-k)≤C 现货 -R 基准收益,T ≤R 基准收益,T *k, R y =0;
[0207] C 调节 That is, the above-mentioned revenue adjustment fee is apportioned according to the market's power generation grid-connected ratio, completing the revenue adjustment mechanism of the entire new energy power generation enterprise. The formula is as follows:
[0208]
[0209] In the formula, C 调节 Adjusting expenses for revenue; Q iis the grid-connected power of each new energy and thermal power enterprise, and Q is the total grid-connected power of the entire market;
[0210] In order to further understand the solution of the present application, this embodiment also provides a specific case, as shown below:
[0211] Table 2 Spot monthly settlement data of power generation enterprises
[0212]
[0213] Assuming that the allowable profit deviation range is 0.1 (that is, the profit adjustment benchmark coefficient), the calculation results of the profit adjustment mechanism for the three new energy enterprises A, B, and C are shown in Table 3:
[0214] Table 3 Results of the new energy spot revenue adjustment mechanism
[0215]
[0216] For new energy companies A, C 现货 -R 基准收益,T *(1+k)>0, the new energy revenue recovery fee is 50-40*1.1=6. The negative number in the new energy spot revenue recovery fee column in the table indicates that the new energy enterprise A pays the spot recovery fee to all power generation enterprises in the market;
[0217] For new energy enterprises B, C 现货 -R 基准收益,T *(1-k)<0, the compensation for new energy losses is 70-80*0.9=-2. The positive numbers in the new energy spot loss compensation column in the table indicate the spot loss compensation that new energy enterprise B obtains from power generation enterprises in the entire market. Similarly, for new energy enterprise C, the spot loss compensation and spot revenue recovery costs of new energy power generation enterprises are shared or apportioned by all power generation enterprises according to the proportion of grid-connected electricity. The settlement results after sharing or apportionment are shown in Table 4:
[0218] Table 4 Results of monthly spot settlement of power generation enterprises after the introduction of new energy revenue adjustment mechanism
[0219]
[0220]
[0221] For new energy enterprise A:
[0222] New energy spot revenue recovery electricity fee allocation and sharing = (-1) * total new energy spot revenue recovery electricity fee * A monthly grid-connected electricity / total grid-connected electricity = (-1) * (-6) * 100 / 1700 = 0.35;
[0223] New energy spot revenue recovery electricity fee allocation and sharing = (-1) * total new energy spot loss compensation electricity fee * A monthly grid-connected electricity / total grid-connected electricity = (-1) * 10 * 100 / 1700 = -0.59;
[0224] After the introduction of the new energy revenue adjustment mechanism, the monthly spot electricity fee = monthly spot electricity fee (including unbalanced funds) + new energy spot revenue recovery electricity fee + new energy spot loss compensation electricity fee + new energy spot revenue recovery electricity fee apportionment and sharing + new energy spot revenue recovery electricity fee apportionment and sharing = 50-6+0+0.35-0.59=43.76;
[0225] The calculation method for other power generation companies is similar.
[0226] From the monthly spot settlement results of power generation enterprises after the introduction of the new energy revenue adjustment mechanism, it can be seen that the market revenue of new energy participating in the spot market has been adjusted after the introduction of the new energy revenue adjustment mechanism. Conventional energy enterprises bear the revenue adjustment costs of new energy enterprises, but it does not affect the overall settlement electricity charges on the power generation side.
