Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The following detailed description is exemplary in nature and is intended to provide further details of the invention. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention.
Examples
An inter-provincial power generation right transaction method for promoting consumption of multiple energy sources, referring to fig. 1, comprises the following steps:
Firstly, a data receiving module receives input information of various energy types and transaction varieties, and a processor determines the energy types and the transaction varieties for power generation right transaction according to the input information;
secondly, the processor calls a computer program stored in the memory, and determines a transaction period and a transaction mode according to the determined energy type and transaction variety for carrying out power generation right transaction;
thirdly, the data receiving module receives the transaction information respectively submitted by the electricity purchasing party and the electricity selling party in the transaction period and stores the transaction information in the memory;
fourthly, the processor calls the computer program and the transaction information stored in the memory to determine a clearing method;
and fifthly, the processor performs transaction settlement according to the clearing method, outputs a transaction settlement result and completes the power generation right transaction.
In another specific embodiment, it should be noted that, in this embodiment, the varieties of power generation right trade and the trade mode thereof are selected as follows:
(1) alternative bundling for multiple energy sources
In the inter-provincial power generation right transaction, if the transferee is a single renewable energy source, due to the problem of output fluctuation characteristics, the power and electricity balance of the giving province can be greatly influenced, the transaction achievement and the dispatching operation safety of a power grid are not facilitated, and therefore in the actual transaction, the power transaction is often carried out by selecting a power transmission mode of bundling multiple energy sources, the external power transmission load is easy to regulate and control, and the reliable supply of power is guaranteed.
When the trade variety is bundled by multiple energy sources, a bilateral negotiation trade mode can be adopted in the power generation right acquirer to carry out energy type matching and income distribution. The subjective intentions of the new energy source units are selected and combined, and then subsequent transactions can be carried out in a centralized bidding mode decoupled by buyers and sellers, so that the mode is beneficial to selecting and bundling multiple energy sources in a proper proportion to obtain the maximum benefit, and meanwhile, the problem of low efficiency caused by coupled bidding can be avoided.
The transaction flow is as follows:
first, the power generation authority transferee negotiates the transaction bilaterally. Firstly, confirming the bundling variety and proportion of multiple energy sources by adopting a bilateral negotiation mode among multiple energy sources acceptors to form a price and electric quantity allocation strategy and an overall electric power-quotation curve;
second, information publicity is involved in the centralized bid transaction. A power generation right acquirer and a power generation right acquirer which are combined by various renewable energy power plants submit a power curve and corresponding power prices in a trading system.
Again, the contract is initially traded. After the power generation right transferor and the transferee negotiate to determine the transaction electric quantity and the price, a preliminary bilateral negotiation transaction contract is formed in the transaction system, an initial bargaining result is formed after the safety check of a scheduling mechanism, and the two parties of the transaction sign a contract according to the initial bargaining result.
And finally, a transaction result is obtained. And the dispatching mechanism carries out safety rechecking on the electric quantity of the power plant transaction contract in the next month before the contract in each month is executed, and the electric quantity after the safety rechecking in each month is taken as a final transaction result.
(2) Clean energy priority replacement
Aiming at a clean energy priority substitution mechanism of inter-provincial power generation right transaction, a centralized bidding method can be adopted, and a renewable energy unit is selected for power generation substitution by a transaction center according to the principle that a transaction direction is transferred from a unit with high cost and heavy pollution to a unit with low cost and light pollution.
The general process of buyer-seller decoupled centralized bidding is as follows:
firstly, the power generation right transferor and the transferee centrally report a power curve and a corresponding power price to the power trading center.
Secondly, the trading center considers various safety constraints to carry out market clearing to form a trading pair, and the power generation right transferor and the transferee only trade with the electric power trading center in the process.
And finally, forming a final transaction result after the safety recheck of the scheduling mechanism.
Aiming at the condition that the renewable energy power consumption responsibility weight of a certain province is not completed, the power generation right transaction of the thermal power plant and the renewable energy power plant can be carried out in a listing transaction mode. The general process is as follows:
Firstly, giving out a listing price and listing electric quantity by a power generation right transferor (a thermal power plant);
secondly, submitting a declaration card picking price and card picking electric quantity by the power generation right transferee;
and finally, carrying out transaction according to a price priority principle, namely, the generator with low picking price is given priority to transaction. When the picking prices are the same, the deal is carried out according to the time-first principle, namely, the first claimant takes precedence over the later claimant, and the sequence is determined according to the time of accepting the claim by the transaction host. The picking price is the transaction price.
(3) Inter-provincial depth peak regulation
The inter-provincial power generation right transaction aiming at deep peak regulation has the core that the condition that external renewable energy cannot be accepted due to insufficient deep peak regulation capacity is avoided through the transfer of the power generation right, and meanwhile, a certain benefit is given to the power generation right transferor, so that the transaction enthusiasm is improved. The situation often appears in a scene that the deep peak regulation must be carried out in the low valley of the electric load in a certain area, so the method is mainly suitable for the low valley load period at night and the season with low electric load in spring and autumn in a time scene.
The trading method is not only suitable for trading of the power generation rights among thermal power generating units. In the aspect of peak regulation capacity, thermal power and hydroelectric generating sets are obviously superior to other types of power supplies, and power generation enterprises such as wind power and photovoltaic generating sets do not have the peak regulation capacity, so that in actual transaction, wind, light and thermal power inter-provincial power generation right transaction aiming at deep peak regulation can improve the external power transmission quantity of renewable energy power, can realize local peak regulation requirements, and has higher feasibility, economic benefit, resource benefit and environmental benefit. Meanwhile, because the marginal power generation cost of renewable energy power is low, the trading price of the power generation right may even be higher than the marginal power generation cost, so that additional benefits are obtained.
When the transaction variety is used as an object to carry out transaction, the transaction is the same as the common transaction variety, and the transaction can be carried out in a centralized transaction mode of decoupling of buyers and sellers, so that the transaction efficiency is greatly improved.
(4) Replacement within a power generation complex
The internal trading method for the power generation right in the group refers to that both the power generation right giving and giving parties are two subsidiaries in the same group, and through an internal substitution method, the power generation income can be guaranteed to be transferred in the group without loss, so that the resistance of power generation right trading is greatly reduced.
Meanwhile, from the alternative relationship of transaction, the two transaction parties replaced inside the power generation group are not different in nature, and the transaction main body is still a clean energy power plant, a thermal power plant and the like. Meanwhile, the transaction varieties can still be bundling transactions, deep peak shaving transactions, priority alternative transactions, pumped storage alternative transactions and the like. This shows that there is a coupling relationship between the trading varieties, i.e. the trading varieties are not absolutely opposite and can be overlapped with each other.
Similarly, taking the multi-energy bundling transaction as an example, the replaced power plant can be a power plant for supplying power to a storage unit, a power plant for regulating the power of a heat pump, a power plant for self-supply of enterprises and the like. Multiple transaction varieties are mutually contained and overlapped to generate multiple benefits.
(5) Pumped storage replacement transactions
The pumping and storage unit participates in inter-provincial power generation right transaction, and the core method is that the external provincial clean energy power replaces the provincial fire power generator set to supply power to the pumping and storage unit, so that the pumping and storage unit can pump water and store power in a low-valley load period, and meanwhile, the power generation amount of the power-receiving fire power generator set is replaced.
The precondition for achieving the inter-provincial power generation right transaction is that the benefits of all parties are not lost, and in the scene that the pumped storage unit participates in the inter-provincial power generation right transaction, the boundary condition for achieving the transaction comprises three aspects:
firstly, the electricity purchasing cost of the pumping storage unit does not rise;
secondly, the replaced thermal power enterprise has a profit space;
and finally, the generating income of the clean energy power plant is not zero.
Under such marginal conditions, in order to obtain a reasonable trading price interval for the pumping participation of inter-provincial power generation right trading, the profit mode and economic characteristics of the pumping unit need to be known first.
When the transaction variety is used as an object for transaction, a bilateral negotiation transaction mode can be adopted, the drawing and storing power station is used as a transferee, the enthusiasm of a thermal power plant is fully utilized for transaction, a centralized transaction mode decoupled by a buyer and a seller can be adopted for transaction, and the transaction efficiency is greatly improved.
(6) Clean energy and self-contained power plant replacement
The rapid development of the self-contained power plant causes the scale of the installed public power supply and the inverse suspension of the absorption load, and the contradiction between supply and demand is prominent, so that the shortage of the peak regulation capacity of the power grid is large, and the operation safety of the power grid is seriously threatened. The replacement transaction is to replace the power generation right of the self-contained power plant enterprise by the new energy enterprise on the basis of ensuring the normal operation of the power grid, fully consuming new energy and meeting the power utilization requirement and external power transmission of the region, so that the power generation amount of the new energy is substantially improved. The self-contained power plant enterprises are the key of the alternative transaction, and the income directly determines whether to participate in the alternative transaction. Therefore, in order to improve market competitiveness of self-contained power plant enterprises and guarantee the goals of maximum self-transaction income and minimum risk, it is necessary to analyze risk factors in alternative transactions and evaluate and control risks, so as to make an effective transaction strategy.
The self-contained power plant enterprise is an important participant of the replacement transaction, and in the replacement transaction, the self-contained power plant enterprise and the new energy enterprise sign a transaction contract, transfer part or all of the power generation right to the new energy enterprise, provide certain peak regulation auxiliary service, complete transaction power consumption on time and pay power consumption cost in time.
The trade varieties are the same as the common trade varieties, a more effective decoupling centralized bidding mode can be adopted, and the self-contained power plant participates in the trade as other power generation right trading transferors.
(7) Forced substitution
The forced replacement transaction is triggered under two conditions:
trigger condition 1: when the heavy pollution weather phenomenon occurs or is about to occur in the receiving end area, the provincial channels have surplus power transmission capacity, the sending end area has clean energy sending capacity, and the market is automatically started. The transaction mode is as follows: and on the premise of ensuring the safe operation of the power grid, sequentially clearing the parts which are not bid for the power transmission and power generation enterprises (the clear power receiving price is not higher than the average price of the power purchasing and power purchasing of the power purchasing and power saving enterprises) continuously, and superposing the power transmission transaction curves formed in the earlier stage until the peak power transmission capacity reaches the upper limit of the available capacity of the power transmission channel. The recommendations are made in the form of monthly incremental transactions that are not made on a regular basis.
Trigger condition 2: when the new clean energy consumption requirement appears at the sending end and the provincial thermal power generating unit is in the minimum mode, namely no consumption space exists in the provincial and the provincial channels are fully sent, the market is opened in a trading mode of organizing the prearranged conventional energy and trading the power generation right of the new clean energy; the condition and price of the prior alternative conventional energy sources of clean energy sources are determined in advance in a pre-branding transaction mode.
When the trade is carried out by the trade variety, a pre-listing trade mode can be adopted, and the general trade flow is as follows:
firstly, the power generation right transferor and the transferee declare a power curve and a power price according to emergency transaction information issued by a transaction center.
And secondly, the two transaction parties sort according to the declared prices, the electricity purchasing party sorts according to the declared prices from high to low, and the electricity selling party sorts according to the declared prices from low to high to respectively form a priority winning bid sequence.
And thirdly, when the daily transaction is executed, the dispatching department respectively dispatches the corresponding generator sets according to the actual emergency situation on the basis of meeting the safety on the basis of the prior bid-winning sequence formed by the pre-listing.
And then, after the emergency transaction is finished, the scheduling department feeds back the pre-listing execution result to the electric power transaction center for information publication.
And finally, the electric power trading center forms a standardized trading contract according to the matching of the actual scheduling result, and the electric power trading center settles accounts in the day.
In another embodiment, the transaction cycles are treated differently according to energy class. When the energy type is hydroelectric generating set power generation, the transaction period is annual transaction. The hydroelectric generating set is used as a power generation right transferee, and can declare next-month electricity price and electric power in a mode of monthly declaring an electric power curve in a mode of a concentrated bidding mode after the annual transaction notice of the power generation right is released, and a month is used as a time period. When the energy category is that the photovoltaic unit generates power, the trading period is monthly trading, the photovoltaic unit serves as a power generation right acquirer, and declares power price and power in the trading period according to peak-to-valley in a power curve mode after the power generation right monthly trading bulletin is issued in a centralized bidding mode. And when the energy type is the power generation of the wind turbine generator, the transaction period is multi-day transaction. The wind turbine generator serves as a power generation right transferee, a centralized bidding mode is adopted, after the power generation right multi-day transaction bulletin is issued, power price and power of the next period are declared in a power curve mode with 30min as a time interval.
In another embodiment, the transaction information is a power-price curve formed for power prices declared by market members.
In another embodiment, the price of electricity may be divided in time segments, which includes:
firstly, taking 7:00-11:00,19:00-23:00 as peak time according to the related national regulations; 23: 00-7 on the next day: 00 is a valley; 11: 00-19: 00 is a flat section, and each day is divided into three time periods of peak time, flat time and valley time, and 90 time periods are formed every month.
Secondly, according to actual electricity consumption historical data of the province where the power generation right transferor is located, 30min or 15min is taken as a cycle, every 30min or 15min is taken as a transaction clearing time period, and each operation day contains 48 or 96 transaction clearing time periods.
For this purpose, the power curves submitted by the electricity buyer and the electricity seller in the transaction period are submitted as follows:
the electric power transaction mechanism uniformly determines the ratio of declared electric power according to divided time intervals, for example, the electric power transaction structure determines the ratio of the electric power to the peak to the valley to be 1:3:2 according to three time intervals of the peak, the valley and the average, the power purchasing party and the power selling party declare according to the ratio when submitting power curves, and the actual delivery is carried out according to the ratio of the peak to the valley to be 1:3: 2.
Or, the power purchasing party and the power selling party automatically determine the proportion according to the divided time intervals, the actual delivery is carried out according to the declaration proportion, for example, in a certain transaction, the power purchasing party and the power selling party declare the power proportion according to the peak, average and valley time intervals, and the declaration proportion of the peak, average and valley of the power selling party is 1: 1: 1, reporting the peak, average and valley ratio of the power purchasing party to be 1: 2: 1.
in another embodiment, the clearing method is a price matching clearing method, which is a method for clearing the competitive trade price by pairing the electric power prices declared by the electricity purchasing party and the electricity selling party. The price formed by the quotation matching clearing method can be only used as a post-settlement basis, the electric power transaction mechanism respectively arranges the transaction plans of the electricity purchasing party and the electricity selling party, the matching corresponding relation is not limited, and the post-sale electricity party and the electricity purchasing party respectively perform settlement and deviation check according to the matching result. After the declaration is ended, the electricity trading mechanism uniformly converts the electricity purchasing price and the electricity selling price declared by the power generation enterprises, the power users, the electricity selling companies and the power grid enterprises into the floor-side trading gate according to the trading bulletin, and the converted electricity purchasing quotation and the converted electricity selling quotation are formed by considering the electricity transmission and distribution price (including the grid loss), the government fund and the added fund. And the converted power purchasing party price is ranked from high to low. In principle, prices are the same, ordered in the order of "time first"; when the conditions are the same, the reported electric quantity is distributed into the traffic electric quantity in equal proportion. The transaction notice is used as the standard. The converted price of the electricity selling parties is sorted from low to high; when the prices are the same, sequencing is carried out according to the sequence of 'renewable energy source priority, energy conservation and environmental protection priority and time priority'; when the conditions are the same, the reported electric quantity is distributed into the traffic electric quantity in equal proportion.
