Abstract

The invention discloses a flexible load modeling method and device of a load side, and the method comprises the steps: constructing an interruptible load model according to the demand response characteristics of an interruptible load; constructing a transferable load model according to the demand response characteristics of the transferable load and the demand response excitation strategy of the transferable load; constructing a user side energy storage model according to the service mode of the user side energy storage power station; performing equivalence on the air conditioner load by adopting the equivalent thermal parameter model, and constructing an air conditioner load model; constructing an electric vehicle load model according to the operation characteristics of different types of electric vehicles; and in combination with the interruptible load model, the transferable load model, the user side energy storage model, the air conditioner load model and the electric vehicle load model, obtaining a load side flexible load model. By adopting the flexible load model of the load side constructed by the invention, the flexible load of the load side can be accurately analyzed, and the coordinated scheduling of various flexible loads can be optimized.

Description

technical field [0001] The invention relates to the technical field of flexible resource analysis, in particular to a method and device for modeling flexible loads on the load side. Background technique [0002] "Flexible load" is defined as a flexible and adjustable load whose power consumption can be changed within a specified interval or transferred between different time periods. In a broad sense, it includes adjustable or transferable loads with demand elasticity, electric vehicles with two-way adjustment capabilities, Energy storage (energy storage, ES), energy storage and distributed power supply, microgrid, etc. Due to its large quantity, fast response, and flexible control, flexible loads have gradually become an important control resource for scenarios such as peak load shaving, smoothing new energy fluctuations, and providing auxiliary services. Therefore, it is urgent to study a method for modeling the flexible load on the load side, so that the flexible load on...
