Abstract
Description
Technical Field
[0001] This invention relates to the field of energy management and optimization technology, and more specifically, to a method for regulating energy resources in a power grid, a storage medium, and an electronic device. Background Technology
[0002] As the world's reliance on renewable energy deepens, especially with the rapid expansion of wind and solar power, the operation of power systems faces unprecedented challenges. These challenges primarily stem from the intermittency and uncertainty of renewable energy generation, leading to a significant increase in the randomness and volatility of both supply and demand. To ensure the safe and stable operation of the power system and improve its capacity to absorb renewable energy, the grid's need for rapid and flexible resource regulation has become extremely urgent. On the other hand, a large amount of existing infrastructure such as thermal power plants, combined heat and power (CHP), and district heating mainly provides power and heat to fixed loads, with relatively rigid operating modes, and their potential regulation capabilities have not been fully explored and utilized. For example, CHP units typically generate heat while generating electricity, but this synchronous production mode limits their flexible regulation capabilities within the power system; district coal-fired or gas-fired boilers are mainly used for winter heating, but may be idle or operate inefficiently in summer, also indicating untapped regulation potential. The significant shortcomings of related technologies in energy resource regulation methods are mainly reflected in the following aspects:
[0003] Most methods in related technologies are limited to the internal workings of the power system, lacking a unified description and modeling of the regulation capabilities of other energy sources such as heat, cooling, and gas, thus failing to achieve cross-energy-source collaborative optimization. Dispatch strategies are coarse-grained; without unified evaluation standards, power dispatching systems struggle to efficiently and accurately select the most suitable resource combinations in different application scenarios (such as peak shaving, peak regulation, and reserve). Regulation strategies in related technologies are often oversimplified, failing to fully utilize the diverse regulatory potential of available resources. The value of upgrading existing facilities is neglected; most related technologies focus on newly added distributed resources while rarely considering the flexible upgrading of existing equipment such as thermal power and combined heat and power plants to improve their regulation capabilities while reducing regulation costs. Multi-energy flow coupling modeling is weak; related technologies do not adequately consider the coupling relationships and dynamic characteristics between multi-energy flow systems such as electricity, heat, and cooling, failing to accurately quantify the regulation potential of existing facilities at different time scales. Cost calculations often rely on a single dimension. When assessing the cost of regulating resources, levelized cost methods in related technologies tend to consider only a single cost indicator, neglecting diversified cost and benefit factors such as retrofitting investments, downtime losses, fuel savings, carbon emission reductions, and subsidies. This results in an incomplete assessment of regulation costs and insufficient basis for decision-making. Although energy resource regulation methods in related technologies can provide a certain degree of power balance and support under normal circumstances, when facing large-scale energy resources, the inadequate consideration of multiple energy resources leads to low efficiency and high costs in energy resource regulation.
[0004] There is currently no effective solution to the above problems. Summary of the Invention

This achieves the technical effect of improving energy resource regulation efficiency and reducing regulation costs, thus solving the technical problem of low energy resource regulation efficiency and high regulation costs caused by incomplete consideration of multiple energy resources.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0019] According to an embodiment of the present invention, a method for regulating energy resources of a power grid is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0020] Figure 1 This is a flowchart of a power grid energy resource regulation method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:
[0021] Step S102: Obtain an energy resource information set, which includes technical parameters, operating boundaries, and transformation characteristic parameters corresponding to various energy resources. The various energy resources include newly added distributed resources and existing transformed resources. Newly added distributed resources refer to energy facilities newly deployed in the current period, and existing transformed resources refer to energy facilities obtained by transforming existing energy facilities before the current period. The operating boundary refers to the condition limits for energy resources to operate normally and provide regulation services.
[0022] Optionally, by collecting information on available energy resources, including technical parameters, operating boundaries, and retrofitting characteristics, a comprehensive information set can be created, covering both newly deployed and upgraded energy facilities. Building this energy resource information set is fundamental to achieving intelligent, efficient, and safe grid regulation services, providing data support for the dynamic management and optimized regulation of energy resources.
[0023] In one optional embodiment, acquiring an energy resource information set includes: obtaining the technical parameters, operating boundaries, and modification characteristic parameters of any energy resource in the following ways: acquiring the technical parameters of any energy resource, wherein the technical parameters include at least: rated power, energy storage capacity, energy conversion efficiency, thermal capacity, response adjustment time, and power adjustment rate; acquiring the operating boundaries of any energy resource, wherein the operating boundaries include at least: charging state upper limit threshold, charging state lower limit threshold, temperature upper limit threshold, temperature lower limit threshold, time from operation stop to operation restart, and upper limit threshold for the number of times any energy resource can be adjusted within a predetermined time; acquiring the modification characteristic parameters of any energy resource, wherein the modification characteristic parameters... It includes at least: marginal cost of modification, modification window period, and post-modification performance improvement coefficient. The marginal cost of modification represents the additional cost incurred for each additional predetermined unit of modification when upgrading any energy resource. The modification window period represents the time period within a predetermined time frame suitable for modifying any energy resource. The post-modification performance improvement coefficient is used to measure the degree of performance improvement of any energy resource after modification compared to before modification. By obtaining the technical parameters, operating boundaries, and modification characteristic parameters of any energy resource, the corresponding technical parameters, operating boundaries, and modification characteristic parameters of various energy resources are obtained. Based on the corresponding technical parameters, operating boundaries, and modification characteristic parameters of various energy resources, an energy resource information set is obtained.
[0024] Optionally, firstly, by collecting the technical parameters of each energy resource, the basic performance and function of the energy resources can be understood. Next, defining the operating boundaries of each energy resource ensures that it participates in grid regulation safely and reliably, avoiding exceeding its limits. Finally, for existing resources undergoing retrofitting, collecting their retrofitting characteristic parameters provides a solid foundation for assessing the rationality and technical feasibility of retrofitting projects, and also quantifies the added value brought by the retrofitting. Integrating this information from multiple energy resources forms an energy resource information set containing details of newly added distributed resources and existing retrofitted resources. By clearly recording the characteristics, capabilities, and limitations of all available energy resources, the precise customization of regulation strategies and the efficient utilization of energy resources can be promoted.
[0025] Step S104: Based on the energy resource information set, multiple standard regulation potential indicators are obtained. Each standard regulation potential indicator corresponds to a different energy resource. The standard regulation potential indicators are used to quantify the regulation capacity of the corresponding energy resources.
[0026] Optionally, based on a comprehensive collection of energy resource information, the regulation capacity of various energy resources can be transformed into a unified and comparable indicator system, namely, standard regulation potential indicators. The establishment of standard regulation potential indicators quantifies the regulation capacity of different types and technologies of energy resources, facilitating comparison and evaluation under a unified standard. This allows for more accurate identification of which energy resources are best suited to current regulation needs, enabling better selection among various energy resources and improving regulation efficiency.
[0027] In an optional embodiment, when multiple standard regulation potential indicators include a first standard regulation potential indicator and a second standard regulation potential indicator, multiple standard regulation potential indicators are obtained based on an energy resource information set, including: dividing multiple energy resources to obtain a first energy resource and a second energy resource, wherein the first energy resource represents an energy resource whose response time does not exceed a preset response time among multiple energy resources, and the second energy resource represents an energy resource whose response time exceeds the preset response time among multiple energy resources; obtaining a first standard regulation potential indicator based on the first energy resource, wherein the first standard regulation potential indicator includes at least the rated power and energy storage capacity of the first energy resource; and obtaining a second standard regulation potential indicator based on the second energy resource, wherein the second standard regulation potential indicator includes at least an equivalent regulation power parameter, and the second standard regulation potential indicator is obtained based on the technical parameters of the second energy resource and the operating boundary of the second energy resource.
[0028] Optionally, firstly, energy resources are categorized into two main types based on their response and adjustment time: primary energy resources and secondary energy resources. Primary energy resources refer to fast-response resources that can quickly respond to grid dispatch demands within a short period (within a preset response time), including but not limited to battery storage, electric vehicles, and gas generators with rapid start-stop capabilities. Secondary energy resources, on the other hand, are slow-response or inertial resources with longer response times (exceeding the preset response time), including but not limited to building thermal inertia, district heating systems, and energy storage facilities in industrial production processes. Next, different standard adjustment potential indicators are defined for these two types of resources. For primary energy resources, their rated power and energy storage capacity are directly used as measures of adjustment capability, as these resources are characterized by their ability to rapidly adjust output power or energy storage status to adapt to short-term changes in power supply and demand. For secondary energy resources, a more complex equivalent adjustment power parameter is used to characterize their adjustment capability. This parameter needs to be derived by combining the energy resource's technical parameters (including but not limited to heat capacity, cold capacity, and maximum temperature variation) and operating boundaries (including but not limited to upper and lower temperature limits and depth of charge and discharge) to reflect the amount of adjustment services the resource can provide over a longer timescale. By differentiating resources with different response speeds and assigning corresponding regulation potential indicators, energy resources and demand can be matched more accurately, promoting the complementary use of different types of resources, thereby improving regulation efficiency and cost advantages.
[0029] In one optional embodiment, a second standard regulation potential index is obtained based on the second energy resource, including: obtaining the equivalent regulation power parameter based on the second energy resource in the following manner:
[0030] ;
[0031] in, Indicates the equivalent regulating power parameter. Indicates the heat capacity of the secondary energy resource. This represents the temperature change of the second energy resource, which is derived from the upper and lower temperature thresholds of the second energy resource. This indicates the response and adjustment time of the secondary energy resource. This indicates the energy conversion efficiency of the secondary energy resource.
[0032] Optionally, since the response time of secondary energy resources is relatively long, their regulation capacity cannot be directly described by rated power and capacity. Therefore, the concept of equivalent regulation power parameters is introduced, and these parameters are converted into adjustable virtual power and capacity indicators through formulas. This not only reveals the true regulation potential of secondary energy resources but also allows them to participate in the flexible regulation of the power grid alongside primary energy resources. By transforming the regulation potential of secondary energy resources into dispatchable virtual indicators, the range of energy resources that can participate in power grid regulation can be greatly broadened.
[0033] Step S106: Obtain the levelized adjustment cost corresponding to each of the various energy resources, wherein the levelized adjustment cost represents the average cost of the corresponding energy resource participating in grid regulation within a preset number of years of use.
[0034] Optionally, by calculating the average cost of each energy resource participating in grid regulation services during its expected lifespan, i.e., the levelized regulation cost, it is possible to standardize the assessment of regulation service costs for various energy resources throughout their entire life cycle, which helps to make the most cost-effective energy resource regulation decisions when facing diverse regulation demands.
[0035] In one optional embodiment, obtaining the levelized adjustment cost corresponding to each of the multiple energy resources includes: obtaining the levelized adjustment cost of any energy resource in the following manner:
[0036] ;
[0037] in, This represents the levelized adjustment cost of any energy resource. This represents the investment cost of any energy resource in any given year. This represents the operating and maintenance cost of any energy resource in any given year. This represents the opportunity cost of any energy resource in any given year. This represents the energy savings achieved by any energy resource in any given year. This represents the carbon emission reduction benefit of any energy resource in any given year. This represents the subsidy revenue for any energy resource in any given year. This represents the amount of effective regulation services provided by any energy resource in any given year. denoted by the preset discount rate, n represents the preset number of years of use for any energy resource, and i represents the index of any year; by using the method of obtaining the levelized adjustment cost of any energy resource, the levelized adjustment costs corresponding to each of the various energy resources are obtained.
[0038] Optionally, the cost of participating in grid regulation using levelized adjustment costs (LAPs) can be comprehensively assessed. The formula for calculating LAPs considers the entire lifecycle costs and benefits of energy resources, including investment costs, operation and maintenance costs, opportunity costs (other benefits forgone or additional costs incurred due to participation in regulation), energy savings (such as fuel cost savings through thermoelectric decoupling), carbon emission reduction benefits (based on carbon trading market value), subsidy benefits, and the amount of effective regulation services provided. By discounting these future years' costs and benefits to the present, LAPs can fairly evaluate the average cost of regulation resources at different time and spatial scales, allowing for comparison of various energy resources on the same scale. Energy resources with lower LAPs imply higher efficiency and can therefore be preferentially selected for grid regulation.
[0039] Step S108: Obtain the current regulation demand of the target power grid, wherein the current regulation demand includes at least the regulation type, the energy expected to be obtained from various energy resources, and the expected regulation duration.
[0040] Optionally, the immediate regulation needs of the target power grid can be specified. Regulation type refers to the specific type of regulation service currently required by the power grid, including but not limited to frequency control, voltage support, peak load supply, and peak shaving (i.e., reducing electricity demand during peak load periods or increasing demand during off-peak periods). The expected energy to be obtained from various energy resources depends on the real-time operating status of the power grid and the predicted load curve. The expected regulation duration refers to the length of time the power grid needs to provide regulation services, which can range from a few seconds to several hours. Different types of regulation needs will have different duration requirements; for example, frequency response may only require a few seconds, while peak shaving services may require several hours. By accurately collecting current regulation demand information, demand and supply can be matched more precisely, avoiding over-regulation or under-regulation, and ensuring the safe and stable operation of the power grid.
[0041] Step S110: Based on multiple standard regulation potential indicators and the levelized regulation costs corresponding to various energy resources, determine the objective function of the current regulation demand.
[0042] Optionally, based on the collected standard regulation potential indicators of various energy resources and the corresponding levelized regulation costs of each energy resource, an objective function is constructed to select the optimal combination of energy resources to meet the current regulation needs of the power grid. This objective function not only optimizes energy resource regulation strategies, ensuring that regulation is carried out at a lower cost while meeting the grid's flexibility requirements, but also effectively promotes the efficient utilization of energy resources and the low-cost operation of the power grid.
[0043] In one optional embodiment, the objective function for determining the current regulation demand is determined based on multiple standard regulation potential indicators and the levelized regulation costs corresponding to each of the various energy resources. This includes: obtaining target energy resources based on multiple standard regulation potential indicators and the levelized regulation costs corresponding to each of the various energy resources, wherein the target energy resources represent a predetermined number of energy resources selected from the various energy resources that match the current regulation demand; and determining the objective function based on the target energy resources.
[0044] Optionally, firstly, by combining the standard regulation potential indicators and levelized regulation costs corresponding to various energy resources, one or more energy resources that match the current grid regulation needs are selected from among the various energy resources; these are the target energy resources. The target energy resources not only possess the ability to meet regulation needs but also provide the required regulation services at a low regulation cost. The selection of target energy resources ensures that the regulation strategy directly targets the current regulation needs, reducing the indiscriminate use of energy resources. Next, based on these target energy resources, an objective function is constructed. This objective function is used to select the most cost-effective and efficient combination of energy resources while meeting the current grid regulation needs, thereby enabling more precise, low-cost, and efficient energy resource regulation of the target grid.
[0045] In an optional embodiment, when there are multiple target energy resources, a target function is determined based on the target energy resources, including: determining the target regulation cost corresponding to each of the multiple target energy resources, wherein the target regulation cost represents the cost of the corresponding target energy resource participating in the target power grid regulation under the current regulation demand; determining the preset weight of the target regulation cost corresponding to each; and performing a weighted summation operation on the target regulation cost corresponding to each and the preset weight of the target regulation cost corresponding to each to obtain the target function.
[0046] Optionally, firstly, the target regulation cost for each target energy resource under the current regulation demand is calculated separately. The target regulation cost reflects the regulation cost of the energy resource under the current regulation demand of the target power grid. Specifically, the target regulation costs corresponding to the multiple target energy resources can be sorted to obtain a target regulation cost sequence. Energy resources with lower target regulation costs in the sequence are assigned higher weights, indicating that these energy resources will be prioritized during regulation; while energy resources with higher target regulation costs are assigned lower weights and are considered less frequently during regulation. Figure 2This is a schematic diagram of an optional target regulation cost sequence according to an embodiment of the present invention. The diagram shows the results of sorting different energy resources (cooling and air conditioning, industrial and commercial energy storage facilities, electric vehicles, and interruptible loads) according to their target regulation costs. The horizontal axis uses unit regulation equivalent cost as a metric, representing the cost per unit (per megawatt, MW) of regulation capacity. Regulation equivalent can be understood as the amount of regulation service provided by an energy resource within a certain period of time. The smaller the unit regulation equivalent cost value on the horizontal axis, the lower the unit cost of the energy resource at that position when providing regulation services.
[0047] For example, taking the decoupling retrofit of a combined heat and power (CHP) unit A in a certain region (such as a city) as an example, the calculation and adjustment process of the target regulation cost is explained. Assume that unit A originally had a rated power of 300 MW and a heating power of 200 MW. The retrofit plan involves an investment of 15 million yuan to install a 50 MW electrode boiler and a 200 MWh thermal storage tank. After the retrofit, it will provide 50 MW of peak-shaving capacity for 4 hours during the evening peak (i.e., reducing power generation by 200 MWh). Assume that the remaining lifespan of unit A is 15 years and the discount rate is 8%. The target regulation cost of unit A can be calculated as follows: Assuming the investment cost is 15 million yuan, the operation and maintenance cost is 150,000 yuan / year, with a present value of approximately 1.28 million yuan, and the opportunity cost (15 days of downtime for retrofit) is a loss of power generation revenue of approximately 4.5 million yuan, then the present value of the total cost is approximately 15 million + 1.28 million + 4.5 million = 20.78 million yuan. Of the present value of the benefits (as a negative cost), the fuel saving benefit (after the renovation, the use of electrode boilers for heating and storage during off-peak hours, replacing part of the natural gas, is expected to save 800,000 yuan annually) is approximately 6.84 million yuan. The carbon emission reduction benefit (annual carbon reduction of 1,000 tons, carbon price of 50 yuan / ton, annual benefit of 50,000 yuan) is approximately 430,000 yuan. The peak shaving benefit (expected to participate in peak shaving 100 times per year, 200 MWh each time, clearing average price of 0.5 yuan / MWh, annual benefit of 10 million yuan) is approximately 85.5 million yuan. The subsidy includes a one-time subsidy of 3 million yuan for flexibility renovation. The total present value of the benefits is calculated to be approximately 6.84 + 43 + 85.5 million + 3 million = 95.77 million yuan. The target adjustment cost can then be calculated as: (20.78 - 95.77) / (200 MWh / time). 100 times / year (15 years) ≈ -0.025 yuan / MWh. The calculation results show that the target regulation cost is negative, indicating that the retrofit project can not only recover its costs over its entire life cycle but also generate significant net profits. In energy resource prioritization, this cogeneration decoupling unit will have an extremely low target regulation cost, placing it at the highest priority among all target energy resources. When peak-shaving demand arises, this unit will be prioritized, followed by other target energy resources with positive target regulation costs.
[0048] Next, a preset weight is assigned to the target adjustment cost of each target energy resource. This weight reflects the relative importance and priority of the energy resource in the adjustment decision, allowing for flexible adjustment strategies to adapt to different operating conditions. By weighted summing of multiple target adjustment costs and their respective weights, the cost and importance of all energy resources can be comprehensively considered, resulting in the objective function. The value of this objective function reflects the total expected adjustment cost, i.e., the total expected cost of multiple target energy resources under the current adjustment demand. The total expected adjustment cost can be obtained as follows: L = Where L represents the total expected adjustment cost, This represents the target adjustment cost of any target energy resource. The preset weight represents the target adjustment cost of any target energy resource, where i represents the index of any target energy resource and n represents the quantity of the target energy resource.
[0049] Step S112: With the goal of minimizing the function value of the objective function, optimize the energy resource regulation of the target power grid to obtain the target energy resource regulation strategy of the target power grid.
[0050] Optionally, optimizing the energy resource regulation of the target power grid with the minimum function value of the objective function as the optimization objective means finding a set of optimal energy resource regulation strategies in the regulation decision-making process to minimize the total regulation cost, thereby enabling flexible and efficient use of energy resources and fully leveraging the regulation potential of various energy resources under different time scales and regulation needs.
[0051] In one optional embodiment, the target power grid is optimized for energy resource regulation with the objective function value being minimized, resulting in a target energy resource regulation strategy for the target power grid. This includes: determining preset constraints, which at least include the target power grid transmitting electricity not exceeding the rated capacity of the transmission lines and the supply and demand of heat not exceeding a preset balance range when regulating thermal energy resources; and determining the target energy resource regulation strategy from multiple initial energy resource regulation strategies based on the preset constraints and with the objective function value being minimized.
[0052] Optionally, optimizing energy resource regulation of the target power grid with the minimum objective function value as the optimization objective is a process of finding the optimal energy resource scheduling strategy under preset constraints. This ensures that energy resource regulation can be achieved at the lowest cost while meeting the safe operation and technical requirements of the power grid. Among all possible initial energy resource regulation strategies, the strategy that satisfies the preset constraints and minimizes the objective function value is selected. This process can utilize optimization algorithms, including but not limited to mixed integer programming and genetic algorithms, to solve for the objective function. The final target energy resource regulation strategy specifies in detail the usage of each energy resource, including but not limited to the start time, stop time, regulation amount, and regulation direction of any energy resource, to ensure that the total cost of energy resource regulation is minimized while achieving efficient utilization of energy resources.
[0053] Through the above steps S102 to S112, the goal of determining the target energy resource regulation strategy can be achieved by acquiring energy resource information sets, multiple standard regulation potential indicators, and the levelized regulation costs corresponding to each of the various energy resources, with the optimization objective being to minimize the function value of the objective function of the current regulation demand of the target power grid. This results in improving the regulation efficiency of energy resources and reducing regulation costs, thereby solving the technical problem of low energy resource regulation efficiency and high regulation costs caused by insufficient consideration of various energy resources.
[0054] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation method. Figure 3 This is a flowchart of an optional power grid energy resource regulation method according to an embodiment of the present invention, such as... Figure 3 As shown, the method includes:
[0055] S1: Perform unified resource modeling, which is the process of acquiring energy resource information set. Establish an information set (basic resource library) that comprehensively covers newly added distributed resources and existing transformed resources (multi-energy type resources), and acquire the technical parameters, operating boundaries, transformation characteristic parameters and adjustment cost parameters (including but not limited to operating costs, opportunity costs, fuel saving benefits, carbon emission reduction benefits, and subsidies) of each type of energy resource in the information set. Among them, multi-energy type resources include but are not limited to energy storage systems, electric vehicles, cold and heat storage, and interruptible loads. The specific implementation process is the same as the aforementioned embodiments, and will not be repeated here.
[0056] S2: Capacity quantification mapping, which involves determining multiple standard regulation potential indicators and acquiring the current regulation demand of the target power grid, unifies the regulation potential of various energy resources under standardized indicators to facilitate comparisons between different resources. This process involves calculating the regulation equivalent for resources with different response times. By calculating the standard regulation potential indicators for various energy resources, for fast-response resources (first energy resource), the regulation equivalent is directly determined by its rated power and storage capacity. For slow-response resources (second energy resource), the available regulation equivalent needs to be calculated using equivalent regulation power parameters. Next, the scenario demand mapping process refers to converting the current regulation demand of the target power grid (including but not limited to peak-shaving demand, frequency regulation demand, reserve demand, and technical requirements) into specific demands for corresponding energy resources. The standardization process ensures that all energy resources can be compared under the same benchmark; the specific implementation process is the same as in the aforementioned embodiments and will not be repeated here.
[0057] S3: The process of benchmarking regulation costs, i.e., determining the levelized regulation cost, involves identifying target energy resources based on current regulation needs, thereby determining the target regulation cost. The calculation of unit regulation cost refers to the cost per unit of regulation equivalent. By calculating the unit regulation cost, the cost required to provide a unit of regulation service for each energy resource can be intuitively understood. The regulation cost comparison process is conducted based on the calculation of the target regulation cost and the determination of the unit regulation cost. Its goal is to rank different energy resources according to their cost efficiency, forming a target regulation cost sequence. The process of obtaining a cost parameter library provides data support for the levelized regulation cost calculation and the target regulation cost. The cost parameter library includes, but is not limited to, investment costs, operation and maintenance costs, lifetime parameters (used to assess the ability of energy resources to maintain a predetermined performance level throughout their lifespan), and degradation models (assessing the health status and remaining lifetime of energy resources at a predetermined future time). The specific implementation process is the same as in the aforementioned embodiments and will not be repeated here.
[0058] S4: Scenario-based optimization decision-making, namely the objective function determination process and the energy resource regulation optimization of the target power grid to obtain the target energy resource regulation strategy. The cost ranking process involves sorting multiple target energy resources according to the target regulation cost of the regulation services they provide, with lower-cost energy resources having higher priority, guiding the weights in the objective function. The optimal resource combination process needs to consider the complementarity and synergy among multiple target energy resources to achieve the goal of minimizing overall cost. Once the optimal resource combination is determined, specific scheduling instructions (target energy resource regulation strategies) are generated, specifying which energy resources should be regulated when, at what intensity, and for what duration. The scheduling execution and feedback process includes issuing regulation instructions to the corresponding energy resource control center, which executes the specific regulation actions. After executing the target energy resource regulation strategy, the regulation results are monitored in real time, and real-time data feedback (including but not limited to regulation accuracy, response time, and actual cost) is collected. The results are compared with the expected target to evaluate the regulation effect and assess the effectiveness and cost of the target energy resource regulation strategy. If a large deviation from the expected target is found, model optimization (adjusting the objective function) is performed to improve subsequent regulation decisions. The specific implementation process is the same as in the previous embodiments and will not be repeated here.
