Description

Technical Field

[0001] The present invention belongs to the field of electric power systems, and in particular relates to a method for evaluating the dynamic benefits of user-side energy storage taking into account comprehensive capacity compensation. Background Art

[0002] In the new power system, a comprehensive and reasonable evaluation of the benefits of massive distributed user-side energy storage can further stimulate the effectiveness of user-side energy storage in participating in the operation of the new power system. The traditional energy storage benefit evaluation method has the following problems in the new power system with new energy as the main body: 1) In the traditional energy storage benefit evaluation, a single electricity price is generally used, without considering the carbon emission price and clean electricity price. With the continuous advancement of the dual carbon goals, carbon emission reduction and clean electricity consumption will be further promoted in the future, making it difficult for traditional methods to be effectively applied to the evaluation of user energy storage in the new power system. 2) Affected by the number of charging and discharging times and the depth of each charging and discharging, the loss of user-side energy storage will change dynamically in each charging and discharging. In the traditional method, fixed charging and discharging losses are generally used to calculate the operating cost of energy storage, and the effectiveness of its cost evaluation needs to be further improved. 3) Since the new power system is mainly based on new energy, the power supply side regulation resources are seriously insufficient; in addition, the new power system needs to tap more resources to reduce carbon emissions and improve the degree of clean electricity consumption. If too much reserve is reserved, the system reserve cost will be too high, reducing the operating efficiency of the new power system. Therefore, it is necessary to tap into the reserve capacity of user-side energy storage and compensate it to reduce the overall capacity reserve cost of the new power system. Traditional methods rarely consider energy storage reserve compensation. A few methods consider power capacity reserve, but do not consider carbon emission reduction capacity and clean electricity capacity, which makes it difficult to adapt to the operation needs of the new power system. 4) The power grid generally provides power capacity compensation, carbon emission reduction capacity compensation, and clean electricity capacity compensation when the energy storage is in operation and not retired. However, due to the number of energy storage charge and discharge cycles and the depth of charge and discharge, its operating life will be affected, resulting in early retirement of energy storage, which in turn affects its capacity compensation. Traditional methods do not consider this aspect enough, which affects the effectiveness of the evaluation results. Therefore, a user-side energy storage dynamic benefit evaluation method that takes into account comprehensive capacity compensation is needed. Summary of the invention

[0052] Step 2. Construct a user-side energy storage cost model that takes dynamic losses into account: Affected by the number of charge and discharge times and the depth of each charge and discharge, the loss of user-side energy storage will change dynamically during each charge and discharge. In traditional methods, fixed charge and discharge losses are generally used to calculate the operating cost of energy storage, and the effectiveness of its cost assessment needs to be further improved. Therefore, the present invention proposes a user-side energy storage cost model that takes dynamic losses into account. According to the user's total investment cost, rated charge and discharge depth, actual charge and discharge depth, number of charge and discharge cycles, etc., a dynamic loss cost model is constructed to dynamically evaluate the operating cost of user-side energy storage and improve the effectiveness of energy storage cost assessment. The model mainly includes a user-side energy storage total investment cost model, which is mainly evaluated based on the equipment cost, installation cost, total operation and maintenance cost, total insurance cost, etc. of the energy storage; a remaining cycle number model for energy storage users, which is mainly evaluated based on the remaining cycle number of energy storage, the SOC information of the user-side energy storage, and the rated discharge depth of the energy storage; a user-side energy storage dynamic loss cost model, which is mainly evaluated based on the rated charge and discharge cycle number of the energy storage, the number of charge and discharge cycles of the energy storage, the remaining cycle number of the energy storage, and the total investment cost of the energy storage;

[0053] The total investment cost model of user-side energy storage is shown in formula (4):

[0054] T ou =θ S +θA +θ Y +θ B (4)

[0055] Where: T ou is the total investment cost of energy storage; θ S ,θ A ,θ Y ,θ B They are the equipment cost, installation cost, total operation and maintenance cost, and total insurance cost of energy storage;

[0062] Step 3: Construct a comprehensive capacity compensation benefit model for user-side energy storage. Since the new power system is mainly based on new energy, there is a serious shortage of regulation resources on the power supply side; in addition, the new power system needs to tap more resources to reduce carbon emissions and improve the degree of clean electricity use. If too much reserve is reserved, the system reserve cost will be too high, reducing the operating efficiency of the new power system. Therefore, it is necessary to tap the reserve capacity of user-side energy storage and compensate it to reduce the overall capacity reserve cost of the new power system. Traditional methods rarely consider energy storage reserve compensation. A few methods consider power capacity reserve, but do not consider carbon emission reduction capacity and clean power capacity, which is difficult to adapt to the operation requirements of the new power system. Therefore, this embodiment constructs a comprehensive capacity compensation benefit model for user-side energy storage, comprehensively considers power capacity compensation, carbon emission reduction capacity compensation, and clean power capacity compensation, and improves the effectiveness of user-side energy storage benefit evaluation. In addition, the power grid generally gives its power capacity compensation, carbon emission reduction capacity compensation, and clean power capacity compensation when the energy storage is in operation and in a non-retired state. However, affected by the number of energy storage charge and discharge cycles and the depth of charge and discharge, its operating life will be affected, resulting in early retirement of energy storage, which in turn affects its capacity compensation. Therefore, this embodiment considers the impact of the dynamic loss of energy storage on its operating life, constructs a user-side comprehensive capacity compensation loss function, and evaluates the comprehensive capacity compensation loss of user-side energy storage;

[0063] Among them, the compensation income model of various capacities of user-side energy storage is shown in formula (7);

[0069] Step 4: Construct a comprehensive benefit evaluation model for user-side energy storage: Based on the user-side energy storage cost model that considers dynamic losses and the user-side energy storage comprehensive capacity compensation benefit model, the comprehensive benefit evaluation model for user-side energy storage is constructed by comprehensively considering charging and discharging benefits, comprehensive capacity compensation, energy storage dynamic loss costs, and comprehensive capacity compensation losses, so as to achieve an effective evaluation of the comprehensive benefits of user-side energy storage.
