Description

Technical Field

[0001] The present invention belongs to the technical field of power system demand response, and more specifically, relates to an inter-provincial spot power market clearing model considering double compensation demand response. Background Art

[0002] The demand response mechanism has brought new opportunities and higher operating efficiency requirements for power trading between provinces. In-depth analysis of this model is of great significance for improving the flexibility of the power system, optimizing resource allocation, and reducing carbon emissions.

[0003] With the gradual promotion of demand response mechanism in the power market, the inter-provincial spot power market faces the challenge of how to reasonably integrate user load regulation and renewable energy generation fluctuations. Power market participants not only need to meet the requirements of real-time supply and demand balance, but also need to deal with the uncertainty brought about by power market price fluctuations and policy and regulatory changes. Therefore, in-depth analysis of the role of demand response in the inter-provincial spot power market clearing model is crucial to optimize power transactions, improve market flexibility and ensure the safe operation of the power system.

[0004] In order to effectively introduce demand response, power market participants need to pay attention to the actual load regulation potential and consider the impact of various technical and economic factors. A comprehensive evaluation method is usually used to analyze the electricity consumption behavior, response flexibility and economic incentives of demand response participants to identify the size of their demand response potential. However, existing research on inter-provincial power market clearing models has relatively little analysis of demand response on the demand side, and lacks in-depth exploration of the impact of demand response on market clearing results. This limitation may result in the optimization effect of the inter-provincial power market clearing model not being able to fully reflect the flexibility of actual power demand.

[0005] In addition, the current research on the inter-provincial spot power market clearing model for demand response is still insufficient in terms of the objective function and constraints of the optimization model. Existing models often fail to fully consider the impact of demand response on the economy and stability of the power system, and lack quantitative analysis of the user load regulation capacity. Therefore, the optimization model for demand response potential needs to introduce factors such as user load flexibility and response time into the objective function to achieve a dynamic balance between supply and demand. In addition, in the setting of constraints, the safety of power grid operation and the fairness of power trading should be taken into account to ensure the effectiveness and operability of the model in practical applications. Through the reasonable design of the objective function and the optimization of the constraints, the actual situation of the power market can be better reflected, and the efficiency and flexibility of the inter-provincial spot power market clearing can be improved. Summary of the invention

[0104] Step 5: Solve the clearing model considering double compensation established in step 4, determine the actual scheduling plan based on the clearing results and output it.

[0105] like Figure 2 As shown, embodiment 2 of the present invention provides an inter-provincial spot power market clearing method taking into account dual compensation demand response. Embodiment 2 further takes into account guaranteed wind and solar power consumption on the basis of embodiment 1. Embodiment 2 includes the following steps:

[0106] Step 1, input cross-provincial regional power grid data; the cross-provincial regional power grid data includes but is not limited to wind and solar power output forecast data, energy storage power generation cost data, interconnection line transmission flow and cost data, thermal power unit start and stop data and thermal power unit output data.

[0107] Step 2: Establish an incentive-based electricity and heat demand response model with constraints, including: analyzing the characteristics of the electricity and heat loads participating in the demand response, establishing mathematical models of the electricity and heat loads before and after the demand response, and constructing electricity and heat load constraints.

[0108] Step 3: Based on the incentive-based electric and thermal demand response model, electric and thermal load energy compensation and carbon quota compensation are taken into account in the demand response, and a comprehensive demand response cost model taking into account double compensation is established; specifically, based on the interactive coupling between electric, thermal and carbon energy, the energy compensation and carbon quota compensation modes are analyzed, and a comprehensive demand response cost model is established using a double compensation method;

[0109] Step 4: Based on the comprehensive demand response cost model taking into account double compensation established in step 3, a one-time clearing model taking into account double compensation is established.

[0110] The objective function of the one-time clearing model is constructed with the minimum total cost of system operation in the region, and the constraint conditions are constructed corresponding to the objective function. So far, Example 2 and Example 1 can use the same steps 1 to 4, including the specific calculation model formula, which will not be repeated. Example 2 uses the clearing model constructed in step 4 of Example 1 as the one-time clearing model, laying the foundation for establishing a secondary clearing model in subsequent steps when necessary.

[0111] It is worth noting that in step 5 of Example 2, the one-time clearing model taking into account double compensation established in step 4 is solved, and based on the clearing results of the one-time clearing model, it is determined whether there is any wind and solar power curtailment in the clearing results. If there is any wind and solar power curtailment, the guaranteed wind and solar power consumption clearing mechanism is implemented and the process goes to step 6; if there is no wind and solar power curtailment, the inter-provincial spot market clearing model is constructed, and the clearing results of the one-time clearing model are the final results.

[0112] Step 6: Based on the judgment result of the one-time clearing in step 5, analyze the wind and solar power abandonment time period of the one-time request, set the priority of wind, solar and storage resource coordinated regulation and thermal power generation, and use the complementary variable penalty method to build a wind and solar power abandonment cost model.

[0113] The wind and solar power curtailment penalty cost model is established in sections, where the K value changes dynamically with the curtailment amount to form a complementary variable form, which is expressed as the following formula (22):

[0117] K1, K2, and K3 are the penalty factors for wind and solar power abandonment corresponding to different wind and solar power abandonment amounts;

[0118] P ls (t) is the amount of wind and solar power curtailment;

[0119] P1 and P2 are the wind and solar power curtailment amounts corresponding to K1 and K2 respectively.

[0120] Step 7, using the wind and solar power abandonment penalty cost model obtained in step 6, establish a secondary clearing model that takes into account the guaranteed consumption of wind and solar power. Specifically, the primary clearing model is modified and the penalty cost for wind and solar power abandonment is added to the objective function.

[0121] On the basis of formula (6), the penalty cost of wind and solar power abandonment is added to the objective function, that is:

[0122]

[0123] Where:
