摘 要

近年来，随着电网用电侧接入具备源荷双重特征的新型负荷的负荷量不断增加，大量可以与电网互动的新型负荷参与到电网的调度作为传统发电调度方式的补充，柔性负荷在电网调度中的作用也因此成为国内外关注的热点。同时也出现了负荷聚合商、智能楼宇等新的用能形式，大量电力负荷可通过不同的需求响应方式参与电网互动，为电网提供了丰富的可调度资源。

Analysis of method of peaking potential of flexible resources in source and reservoir

Abstract

In recent years, as the load on the power-side side of the grid is increased, the new load with the dual characteristics of the source and the load is increasing. A large number of new loads that can interact with the grid participate in the dispatching of the grid as a supplement to the traditional power generation dispatching mode. The flexible load is in the grid. The role of scheduling has therefore become a hot spot at home and abroad. At the same time, new energy consumption forms such as load aggregators and intelligent buildings have emerged. A large number of power loads can participate in grid interaction through different demand response modes, providing abundant schedulable resources for the power grid.

By studying the development and practical application of demand response at home and abroad, this paper obtains the conditions needed to establish a mature demand response market and the development space of China's current power grid dispatch market. By grasping the flexible resources to participate in different types of tuning involved in grid dispatching operation Peak resources, flexible loads and energy storage equipment, from the perspective of flexible resources as grid dispatching resources, classify the flexible loads that China is currently participating in grid dispatching operations and establish mathematical expressions based on their scheduling modes and response characteristics. By modeling different types of loads, combining the scheduling requirements of various operational scenarios such as peak-cutting and valley filling, and eliminating clean energy, the paper focuses on analyzing and quantifying the flexible load participation in grid dispatching capability, analysis of power grid peaking resources and design research on peaking resources and analyzing the response characteristics of multiple types of flexible load resources about matching with grid dispatching requirements and the potential to participate in grid dispatching.
