Description

Technical Field

[0001] The present invention relates to the field of power market transactions and intelligent management and control technologies, and specifically to an intelligent management and control platform for power market ramp-up and multi-market integrated transactions. Background Art

[0002] With the deepening of electricity market reform, the electricity spot market and ancillary services market have been gradually established and improved, playing a significant role in improving the operational efficiency of the power system and promoting the integration of renewable energy. However, with the integration of a high proportion of renewable energy, the demand for flexibility in the power system has increased significantly. In particular, when the load fluctuates rapidly or the output of renewable energy fluctuates, the power grid needs to have rapid ramping capabilities to maintain supply and demand balance and system stability. To this end, ramping ancillary services, as an emerging type of flexibility resource trading, have gradually attracted attention. However, the current linkage mechanism between ramping ancillary services trading and the electricity spot market and existing ancillary services market is still imperfect, resulting in low market efficiency and difficulty in fully utilizing the role of flexibility resources.

[0003] Specifically, in existing technologies, the electricity spot market usually adopts an operating model that combines day-ahead pre-clearing with a real-time market, while ramping auxiliary service transactions lack an effective connection mechanism with the spot market in terms of declaration, boundary condition preparation, price formation, and optimized clearing. In addition, there is also a lack of coordination between ramping auxiliary services and existing auxiliary service varieties such as frequency regulation auxiliary services. For example, the profit distribution mechanism for market players participating in frequency regulation and ramping transactions is unclear, and the possible overlap between reserved frequency regulation capacity and reserved ramping capacity has not yet been resolved. This not only affects the enthusiasm of market players to participate, but may also lead to market resource mismatch and efficiency loss. At the same time, the existing electricity market technical support system has relatively single functions and cannot meet the needs of coordinated operation of multiple types of market players and multiple trading varieties, which limits the actual implementation and promotion of ramping auxiliary service transactions.

[0004] In summary, existing technologies have significant shortcomings in the design of the connection mechanism between ramping ancillary services and the spot and ancillary service markets, and lack a complete trading system software to support the efficient operation of multi-market integrated trading. Therefore, there is an urgent need to develop an intelligent management and control platform that can effectively couple ramping ancillary services with the spot and ancillary service markets. By optimizing the market connection mechanism and developing comprehensive trading system software, we can enhance the grid's ramping capabilities, promote the absorption of new energy, and promote the efficient and stable operation of the power market. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention aims to provide an intelligent management and control platform for power market ramping and multi-market integrated transactions, to achieve efficient connection and coordinated operation of ramping auxiliary service transactions in the power market with the spot electricity energy market and the frequency regulation auxiliary service market, to enhance the dispatching capacity of the grid's flexible resources, to promote the consumption of new energy, and to provide a fair and transparent trading environment for various types of market players.

[0026] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The present invention provides an intelligent management and control platform for power market ramping and multi-market integrated transactions. Its core lies in achieving efficient coordinated operation of ramping auxiliary service transactions with spot power energy markets and frequency regulation auxiliary service markets through modular design. Figure 1 To the attached Figure 6 Specific embodiments of the present invention are described in detail.

[0028] The system structure of the present invention is as follows Figure 1As shown, it mainly includes the ramp-up auxiliary service trading module, the multi-market coupling interface module and the comprehensive evaluation and analysis module. These modules are connected through the network to form a complete intelligent management and control platform. The ramp-up auxiliary service trading module includes a boundary condition generation unit, a declaration management unit, an optimization clearing unit and a capacity reservation coordination unit; the multi-market coupling interface module is equipped with a multi-market data synchronization component and has an intelligent scenario configuration function; the comprehensive evaluation and analysis module is responsible for dynamically evaluating the transaction execution effect and providing a visual display function. The operation process of the entire system is centered on the operation of market operators. For specific operation processes, see Figure 2 .

[0029] In practical applications, market operators first need to obtain day-ahead and real-time spot market operational data from the boundary condition generation unit. This data includes, but is not limited to, load forecasts, renewable energy generation forecasts, and spot market price signals. Based on this data, the boundary condition generation unit generates the boundary conditions required for ramping auxiliary service transactions, such as ramping demand, time window constraints, and price limits. Subsequently, the declaration management unit receives transaction declarations from various market entities, including power generation companies, energy storage operators, and distributed energy users. Declarations typically include declared capacity, bid curves, and technical parameters. The optimized clearing unit performs optimized clearing calculations based on these declarations and spot market price signals, using a linear programming algorithm to solve the objective function to maximize social welfare. The objective function is expressed as: MaxZ = ∑(Pi × Qi) - ∑Ci(Qi), where Pi represents the bid price of the i-th market entity, Qi represents its declared capacity, and Ci(Qi) represents the cost function. Constraints include supply and demand balance, ramp rate limits, and unit technical characteristics. The transaction results generated by the optimized clearing unit serve as the basis for subsequent modules.

[0030] The multi-market coupling interface module exchanges data with the ramping auxiliary service transaction module through the multi-market data synchronization component to ensure seamless connection of transaction information between markets. The multi-market data synchronization component has a data adaptation function, which can synchronize the ramping auxiliary service transaction results with the spot electricity energy market and the frequency regulation auxiliary service market in real time. For example, in peak load scenarios (such as Figure 3 (as shown), market operators can pre-set the priority and coordination strategies for ramping auxiliary service transactions. When specific scenarios are triggered, the multi-market coupling interface module automatically adjusts the connection between ramping auxiliary service transactions and other markets. For example, in a scenario with fluctuations in renewable energy, if wind power or photovoltaic power generation suddenly increases, the multi-market coupling interface module will send instructions to the ramping auxiliary service transaction module to optimize the scheduling of ramping resources to adapt to the fluctuations in renewable energy. In addition, the optimization clearing unit can dynamically optimize the clearing results of ramping auxiliary service transactions based on the operational data provided by the comprehensive evaluation and analysis module, thereby improving system response speed.

[0031] The capacity reservation coordination unit is an important part of the ramp-up auxiliary service transaction module. Its operating principle is as follows: Figure 4 As shown. When the frequency regulation capacity reserved by the frequency regulation unit conflicts with the ramping capacity, the capacity reservation coordination unit pushes prompt information to the market operator through the comprehensive evaluation and analysis module to assist in adjusting the capacity allocation strategy. For example, if the system predicts that the ramping demand will increase significantly within a certain period of time and may affect the abundance of frequency regulation resources, the comprehensive evaluation and analysis module will automatically send an early warning message to the relevant market players and provide optional response measures for them to confirm and implement. Response measures may include temporarily adjusting the operating status of the frequency regulation unit, activating backup ramping resources, etc. This dynamic allocation mechanism can maximize the use of flexibility resources while ensuring the safe and stable operation of the power grid.

[0032] In order to ensure the security of data interaction, the data transmission between the ramp-up auxiliary service transaction module and the multi-market coupling interface module adopts a layered encryption mechanism. Figure 6 As shown in the figure, the layered encryption mechanism combines physical-layer encryption and application-layer encryption, performing multi-level encryption processing before data transmission, and decrypting each layer at the receiving end. Physical-layer encryption uses the AES-256 algorithm to encrypt data packets, while application-layer encryption uses the RSA algorithm to re-encrypt key fields. Furthermore, the comprehensive assessment and analysis module features redundant data storage, regularly performing distributed backups of historical data and assessment results of ramp-up assistance service transactions. In the event of data loss or corruption, critical data can be quickly restored to ensure stable system operation. For example, if data on a node is lost due to a network failure, the system automatically retrieves backup data from other nodes to ensure uninterrupted transactions.

[0033] The voice interaction unit is an innovative function of the hill climbing assistance service transaction module. Its control process is as follows: Figure 5 As shown. Market operators can use the voice interaction unit to issue instructions to the optimization and clearing unit, such as "pause the current trading process" or "adjust ramp capacity." The voice interaction unit converts the voice instructions into operation signals and transmits them to the optimization and clearing unit, which then generates corresponding trading decisions based on the received operation signals. For example, if a market operator discovers an anomaly in a transaction, they can quickly pause the transaction process and activate the alarm mechanism through voice commands. The multi-market coupling interface module also has a permission sharing function, allowing market operators to temporarily grant other users the relevant permissions for ramping auxiliary service transactions. Authorized users can participate in trading decisions through their terminal devices, and when sharing permissions, the authorized time range and operation permission level can be set. For example, a senior manager can grant the technical support team the permission to "view trading results" but not modify trading parameters.

[0034] The optimized clearing unit utilizes a closed-loop feedback control approach, dynamically adjusting clearing strategies by monitoring the actual execution of ramping auxiliary service transactions in real time. For example, if it detects a deviation between the actual execution result and the expected target, the optimized clearing unit automatically suspends the current transaction process and sends an alert to market operators through the comprehensive evaluation and analysis module. The alert information includes the cause of the deviation and a suggested solution. Simultaneously, the optimized clearing unit recalculates the clearing results based on the latest data to ensure that transaction objectives are achieved. The multi-market coupling interface module also features an interface for integrating with external energy management systems, enabling coordinated control of external resources such as distributed energy resources and energy storage systems. For example, when renewable energy generation surges, the multi-market coupling interface module automatically sends instructions to the ramping auxiliary service transaction module to optimize the scheduling of ramping resources to accommodate the fluctuations in renewable energy generation. This coordinated control mechanism significantly enhances the flexibility and adaptability of the power grid.

[0035] The Comprehensive Assessment and Analysis Module, connected to the Ramping Assistance Service Trading Module and the Multi-Market Coupling Interface Module via a network, is responsible for dynamically evaluating the effectiveness of ramping assistance service transactions and analyzing trends based on historical data. For example, the Comprehensive Assessment and Analysis Module analyzes the changing trends in ramping demand based on the past week's trading data and predicts ramping demand for the coming period. The assessment results are displayed graphically on a visual interface, allowing market operators to intuitively understand the status of trading operations and obtain optimization suggestions. For example, if ramping demand continues to increase during a certain period, the Comprehensive Assessment and Analysis Module will recommend that market operators reserve additional ramping resources in advance to mitigate potential risks.

[0036] The various intelligent functions of this invention meet the diverse needs of market operators. For example, the intelligent scenario configuration function allows market operators to pre-set the priority and coordination strategy of ramp-up assistance service transactions based on different market operation scenarios. In emergency ramp-up scenarios, the multi-market coupling interface module automatically adjusts the connection between ramp-up assistance service transactions and other markets, ensuring flexible response to different scenario requirements. In addition, the voice interaction function improves operational convenience, and the permission sharing function enhances the system's collaborative capabilities.

[0037] In summary, this invention, through its modular design and intelligent functionality, achieves efficient integration of ramp-up auxiliary service transactions with the spot electricity market and the frequency regulation auxiliary service market, improving the efficiency of multi-market collaborative operations. Furthermore, this invention dynamically adjusts ramp-up auxiliary service transaction strategies based on the grid's operating status, enhancing the grid's adaptability to fluctuations in renewable energy sources. Data exchange is secure, and the data redundancy storage function of the comprehensive assessment and analysis module ensures stable system operation.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
