Embodiment Construction

[0033] In order to clearly introduce the technical solution provided by the present invention, the technical solution will be described in detail below in conjunction with the accompanying drawings.

[0034] The present invention proposes a large-scale feeder demand response potential assessment method based on load composition identification, using the changes and characteristics of the typical load in different seasons, dates, and time load curves in the corresponding climate zone to establish a typical load model library, and using an optimization method on this basis to calculate Typical load configurations for feeder nodes and assess the overall physical response potential.

[0035] as attached figure 1 As shown in the evaluation flow chart, the evaluation method provided by the present invention specifically includes:

[0036] (1) Obtain the load curve of the feeder to be evaluated, and obtain the load curve of the part to be identified;

[0037] The typical working da...

Abstract

The invention provides an urban power grid large feeder demand response physical potential assessment method comprising the steps of drawing a load curve to be identified, building a typical load database, getting the type and number of typical loads under a feeder, and calculating the physical potential of the typical loads and the aggregate physical response potential of the overall loads of the large feeder. Through the technical scheme provided by the invention, the load composition of a large feeder system can be clearly identified, and the demand response physical potential of the load of a large feeder can be effectively assessed.

Description

technical field [0001] The invention relates to the technical field of power system automation analysis, in particular to an evaluation method for the physical potential of large-scale feeder demand response in urban power grids. Background technique [0002] The rapid development of smart grids makes demand response resources an important means to improve grid regulation capabilities, and DR potential assessment is the basis for formulating reasonable demand response policies or electricity price mechanisms. [0003] At present, there are many reports on the DR potential of a single device, a single commercial or residential building. However, compared with individual loads or a single building, power companies pay more attention to the DR dispatchability potential of large feeders after a large number of load aggregations , and the DR dispatchability potential of large feeders depends on the identification of the load composition of large feeder nodes. Load composition id...
