[0038] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0039] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides a power system dispatching method considering flexible loads, characterized in that:

[0040] S1: Develop a dispatching model based on regional power generation resource endowment and flexible load composition.

[0041] Developing a dispatching model includes analyzing the distribution, scale, technical and economic characteristics of various types of power generation resources in the region.

[0042] Evaluate the stability, reliability and economy of each power generation resource, and determine the priority and scheduling strategy of each power generation resource in the power system.

[0043] Classify and count the flexible loads in the area.

[0044] Analyze the response characteristics, regulation capabilities, regulation range and dispatching costs of various types of flexible loads, and evaluate the potential and role of various types of flexible loads in power system dispatching.

[0045] Based on the analysis results of resource endowment and flexible load composition, various scheduling mode plans are formulated.

[0046] Consider scheduling requirements at different time scales and scheduling strategies under different operating scenarios.

[0047] Design incentive-compatible mechanisms to meet the properties of incentive compatibility, individual rationality, and social welfare maximization.

[0048] Classify and count the flexible loads in the area, including large users, small and medium loads, and load aggregators.

[0049] S2: Use dynamic electricity prices and sign contracts to guide high energy-consuming loads to prioritize renewable energy consumption.

[0050] Guiding high-energy-consuming loads to give priority to the consumption of renewable energy includes formulating flexible electricity price strategies based on the supply and demand situation of the electricity market and the power generation of renewable energy; when renewable energy power generation is sufficient but demand is insufficient, lowering electricity prices to stimulate electricity consumption, especially consumption by high-energy-consuming loads.

[0051] Ensure the transparency of electricity price information so that users with high energy consumption loads can understand electricity price changes in real time.

[0052] Through the incentive and constraint effect of electricity prices, high energy-consuming loads are guided to increase electricity consumption when renewable energy generation is sufficient, and reduce electricity consumption when renewable energy generation is insufficient.

[0053] Design contract terms to clarify the rights and obligations between high-energy-load users and power grid companies.

[0054] Through contracts, the electricity demand of high-energy-consuming loads can be matched with the power generation of renewable energy to achieve demand-side response; power grid companies can adjust the electricity consumption and electricity prices in the contract based on the power generation forecast and real-time situation of renewable energy to guide the electricity consumption behavior of high-energy-consuming loads.

[0055] A profit-sharing mechanism is set up in the contract. For the increased electricity consumption of high-energy-consuming loads when renewable energy generation is sufficient, the power grid company will give preferential electricity prices or subsidies to encourage them to participate more actively in the consumption of renewable energy.

[0056] S3: Adopt peak electricity price and interruptible load mechanism.

[0057] S4: Improve the incentive and compensation mechanism for flexible loads to participate in grid dispatching.

[0058] Improve the incentive and compensation mechanism for flexible loads to participate in grid dispatching, and encourage users to actively participate in grid dispatching through economic incentives. The implementation methods are as follows:

[0059] Clarify the principles of incentive compensation: principle of fairness; principle of incentive.

[0060] Design a reasonable compensation mechanism: set corresponding compensation standards according to the reduction or increase in user load; considering the power supply and demand situation and renewable energy power generation situation in different periods, different compensation standards can be set to better guide users to participate in grid scheduling.

[0061] Specifically, a reference load is determined.

[0062] First, it is necessary to determine the user's benchmark load, that is, the user's average load level under normal circumstances, which can be obtained by analyzing the user's historical electricity consumption data.

[0063] Set the load change range.

[0064] Different load change intervals are set according to the user's baseline load; for example, the load change can be divided into multiple intervals such as a reduction of less than 5%, a reduction of 5%-10%, a reduction of more than 10%, an increase of less than 5%, an increase of 5%-10%, and an increase of more than 10%.

[0065] Establish compensation standards.

[0066] For each load variation interval, a corresponding compensation standard is set; the compensation standard can include fixed compensation and variable compensation.

[0067] Fixed compensation: Based on the contract signed by the user, a certain basic compensation is given to encourage the user to participate in grid dispatch; Variable compensation: Different variable compensation standards are set according to the actual reduction or increase in the user's load, as well as the power supply and demand situation and renewable energy generation situation in different periods of time; for example, in periods when renewable energy generation is sufficient but demand is insufficient, higher variable compensation can be provided for users who reduce their load; and in periods of peak electricity demand, certain variable compensation can be provided for users who increase their load to balance the supply and demand of the grid.

[0068] Establish effective incentives: Sign interruptible load contracts with users to clarify the rights and obligations of both parties, as well as compensation standards and methods; notify users in advance when they are required to participate in grid dispatch so that they can make corresponding preparations; provide real-time feedback to users.

[0069] Provide real-time feedback, including the effectiveness of its participation in grid dispatch and the compensation obtained.

[0070] S5: Model the grid configuration, user bodies, and load aggregation units in a collective manner.

[0071] Grid configuration modeling includes

[0072] Topology model establishment: The power grid topology is abstracted into nodes and branches connecting the nodes, and the topological structure of the power grid is described by the connection relationship between the nodes; considering the information of the nodes and branches at the same time can more accurately describe the topological structure of the power grid.

[0073] Application of linear models: Utilizing the linear characteristics of each component in the power grid, power flow models, voltage stability models and dynamic stability models are established to simplify the complex nonlinear calculation process.

[0074] User modeling includes

[0075] User behavior model: records users' specific access behaviors and generates user behavior logs for subsequent analysis and modeling.

[0076] User interest model: Evaluate the user's attention to the information items they visit based on their behavior patterns; extract and quantify the user's interests and build a user interest model.

[0077] Dynamic tracking mechanism: A dynamic tracking mechanism is provided to capture these changes and thus distinguish the differences between different interests.

[0078] S6: Formulate power operation and dispatching strategies.

[0079] S7: Introduce the SCADA acquisition system, use the system's historical data accumulation, combine the historical data of the data record, and obtain the all-weather load forecast value through calculation methods.

[0081] The dispatch mode formulation module 100 formulates a dispatch mode according to the characteristics of power generation resources and flexible loads in the region.

[0082] The dynamic electricity price and load guidance module 200 formulates an electricity price strategy to guide load regulation according to the supply and demand situation of the electricity market and the power generation situation of renewable energy.

[0083] The incentive mechanism module 300 participates in the dispatching of the power system and improves the enthusiasm of load regulation through compensation measures.

[0084] The flexible load classification and statistics module 400 analyzes the response characteristics, regulation capability, regulation range and dispatching cost of the flexible load to evaluate its potential and role in power system dispatching;

[0085] The grid configuration and modeling module 500 models the grid configuration, user bodies and load integration units in a collective manner in order to formulate a power operation dispatching strategy.

[0092] Table 1 Experimental comparison table

[0093]

[0094] Data interpretation and validation

[0095] Renewable energy utilization rate:

[0096] Traditional scheduling methods fail to fully consider the regulation capacity of flexible loads and the volatility of renewable energy, resulting in low utilization of renewable energy.

[0097] This application method guides high-energy-consuming loads to prioritize the consumption of renewable energy through dynamic electricity prices, contract signing and other mechanisms, significantly improving the utilization rate of renewable energy.

[0098] Grid peak load reduction rate:

[0099] Traditional dispatching methods lack flexible regulation of user electricity consumption behavior, and the peak load of the power grid is high.

[0100] This application method encourages users to reduce electricity consumption during peak hours and increase electricity consumption during off-peak hours through mechanisms such as peak electricity prices and interruptible loads, thereby achieving peak shaving and valley filling and effectively reducing the peak load of the power grid.

[0101] Grid operation risk index:

[0102] Traditional dispatching methods lead to increased risks in grid operation when faced with an imbalance in electricity supply and demand.

[0103] The method of this application reduces the risk of power grid operation through a more sophisticated power dispatching strategy, including price adjustment, power generation target control, peak power limitation, etc.

[0104] User Engagement:

[0105] Traditional scheduling methods lack economic incentives and have low user participation.

[0106] This application method improves the incentive compensation mechanism for flexible loads to participate in power grid dispatching, increases user participation, and promotes the healthy development of the power market.

[0107] Power dispatch cost reduction rate:

[0108] Traditional dispatching methods result in high power dispatching costs due to the lack of flexibility in dispatching strategies.

[0109] The present invention reduces the power dispatching cost and improves the optimal allocation and efficient utilization of power resources by optimizing the power dispatching strategy.

[0110] Carbon emissions reduction:

[0111] Traditional dispatching methods do not fully consider the use of renewable energy and the optimization of grid operation, resulting in high carbon emissions.

[0112] The application method significantly reduces carbon emissions by improving the utilization rate of renewable energy and reducing the peak load of the power grid, thus helping to achieve green and sustainable development.

[0113] In summary, by comparing the key indicators of the traditional dispatching method and the method of the present application, it can be clearly seen that the advantages of the method of the present application in the dispatching of power systems considering flexible loads; the method of the present application not only improves the utilization rate of renewable energy and the stability of power grid operation, but also reduces power dispatching costs and carbon emissions, while increasing user participation and promoting the healthy development of the power market; these data fully verify the beneficial effects of the method of the present application.

[0114] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
