Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a method for evaluating the continuous regulation capabilities of multiple types of load-side resources and related devices. Background Art

[0002] Although there are many load-side resources with great regulation potential, their individual capacity is small, their distribution is dispersed, and their regulation performance varies greatly. A single resource or a single type of resource is difficult to meet the grid regulation needs in terms of response time, regulation capacity, duration, etc. Therefore, potential assessment of a single or single type of load-side resource cannot directly support grid regulation operations.

[0003] Specifically, current load regulation potential assessment methods mostly focus on the power regulation potential of resources, and do not adequately consider characteristics such as resource regulation duration and response time. In addition, load-side resource aggregation technologies mostly perform direct aggregation according to resource categories or grid topology connection relationships, and fail to fully rely on grid regulation scenarios to constrain response time, duration, and other aspects, resulting in their aggregation results being unable to directly support grid regulation decisions. Summary of the invention

[0004] The purpose of the present invention is to provide a method and related device for aggregating and evaluating the continuous regulation capabilities of multiple types of load-side resources to overcome the defects of the prior art. Under the constraints of given response time, start time, and duration, the present invention screens and constructs an adaptive load-side resource set, and evaluates the aggregate regulation capabilities of multiple types of distributed resources to provide support for active power regulation decisions of the power grid.
