Description

Technical Field

[0001] The present invention relates to the technical field of adjustable load resource aggregation, and in particular to an aggregation service system and a power grid for adjustable load resources. Background Art

[0002] In today's power system, demand-side resources are diverse and have huge differences in characteristics. Among them, adjustable loads, as an important component, have diverse situations. For example, some adjustable loads are currently in a fault state, but the fault may be eliminated later; some are not currently approved, and can only participate in scheduling after subsequent approval. However, these special adjustable load resources have not yet been effectively involved in the dispatching plan of the power system.

[0003] As for the classification modeling and aggregation methods of demand-side adjustable load resources, the current design has certain limitations. Usually, these methods take into account factors such as the importance level of the load and the size of the control area, but are only applicable to those adjustable load resources that can directly participate in the dispatch. For those adjustable load resources that need to be cleared before they can participate in the dispatch, and those that need to be approved before they can participate in the dispatch. Specifically, the current aggregation service system has obvious deficiencies in dispatch management. Since there is no clear setting for the attributes of participating in the dispatch, the system cannot automatically distinguish between adjustable load resources that directly participate in the dispatch, participate in the dispatch after the fault is eliminated, and participate in the dispatch after approval. This results in the system being unable to automatically operate according to the set attribute requirements, which seriously affects the efficiency and accuracy of the power system dispatch. For example, in actual power dispatch, if the adjustable load in an industrial area is temporarily unable to participate in the dispatch due to equipment failure, but the system cannot identify this situation and still dispatches in the conventional way, it may cause an imbalance between power supply and demand. For another example, the adjustable load resources in certain specific areas need to be approved before they can participate in the dispatch, and since the system cannot automatically distinguish this attribute, there may be erroneous operations of dispatching without approval, causing a series of problems.

[0004] In summary, solving the problem of imperfect dispatching management scheme of aggregation service system so that it can fully consider the adjustable load resources in various special situations and realize automatic differentiation and operation according to the set attribute requirements has become a key technical problem that needs to be solved urgently in the current power system optimization.

[0046] Specifically, according to the above-mentioned classification identifier corresponding to the above-mentioned load resources in the above-mentioned classification list, the above-mentioned load resources are stored in three different preset areas, namely, a first preset area, a second preset area and a third preset area, wherein the first preset area is used to store illegal resources among the above-mentioned load resources, the second preset area is used to store resources whose faults are to be repaired among the above-mentioned load resources, and the third preset area is used to store the above-mentioned load resources that can be used for adjustment.

[0047] The adjustment module is used to calculate the dispatch coefficient value according to the above-mentioned demand power consumption and the above-mentioned dispatch load resource list, sort the above-mentioned load resources according to the above-mentioned dispatch coefficient value, and adjust them in sequence.

[0048] Specifically, the market electricity price, the target electricity, the above-mentioned demand electricity consumption, the response level and the target weight are obtained, and the response coefficient of the above-mentioned load resource is obtained by querying the first mapping relationship according to the above-mentioned response level. The above-mentioned market electricity price, the above-mentioned target electricity, the above-mentioned demand electricity consumption, the above-mentioned response coefficient and the above-mentioned target weight are substituted into the first target formula e=L / X+G*Y / J to calculate the scheduling coefficient e of each of the above-mentioned load resources, and the above-mentioned scheduling coefficient values ​​e are sorted in order from large to small, and the above-mentioned load resources are divided into high-priority load resources, medium-priority load resources and low-priority load resources, and are scheduled in the order of high, medium and low priority.

If it is not the above-mentioned target level, the load resource is regarded as very important and cannot be scheduled, and the classification identifier of the load resource is determined as the first identifier, indicating that the load resource will not be adjusted.

[0077] When the importance level corresponding to the load resource is the target level, the dispatch identifier is the second dispatch identifier, and the authentication fails, the classification identifier of the load resource in the classification list is determined as the second identifier, and the second identifier is used to indicate that the load resource is an illegal resource;

If it is the above-mentioned second scheduling identifier C3, that is, the above-mentioned load resource needs to be authenticated and can only participate in the adjustment after the authentication is passed, then continue to authenticate. If the authentication fails or the authentication fails, the classification identifier of the load resource is determined as the second identifier, indicating that the load resource is an illegal resource.

[0079] When the importance level corresponding to the load resource is the target level, the dispatch identifier is the first dispatch identifier, and the repair is not completed, the classification identifier of the load resource in the classification list is determined as the third identifier, and the third identifier is used to indicate that the load resource is not temporarily involved in the adjustment;

[0080] Specifically, determine the above-mentioned importance level corresponding to the above-mentioned load resource. If it is the target level three load A3, continue to determine the scheduling identifier of the above-mentioned load resource. If it is the above-mentioned first scheduling identifier C2, that is, the above-mentioned load resource needs to be repaired before it can be adjusted. When the repair of the above-mentioned load resource is not completed, the classification identifier of the above-mentioned load resource in the above-mentioned classification list is determined as the third identifier, indicating that the above-mentioned load resource is not temporarily involved in the adjustment.

[0081] When the importance level corresponding to the above-mentioned load resource is the target level, the above-mentioned dispatching identifier is the above-mentioned second dispatching identifier and the authentication is passed, or the above-mentioned dispatching identifier is the above-mentioned third dispatching identifier, the classification identifier of the above-mentioned load resource in the above-mentioned classification list is determined as the fourth identifier, and the above-mentioned fourth identifier is used to characterize that the above-mentioned load resource can be used for adjustment.

[0082] Specifically, determine the above-mentioned importance level corresponding to the above-mentioned load resource.
