摘要/Abstract

摘要： 间歇性可再生能源发电大量接入电力系统对系统运行灵活性提出了很高的要求。为解决实时调度中系统爬坡和滑坡能力不足问题，美国的一些独立系统运行机构（independent system operator， ISO）提出了一种新的电力市场产品——灵活调节产品（flexible ramping product， FRP），即通过预留额外的灵活性容量来满足系统可能的爬坡和滑坡需求，从而提高系统运行灵活性以便应对多种运行情况。首先，介绍电力系统运行灵活性的基本概念和相关问题，指出在任意时间尺度和多种复杂运行情况下能够保证供需平衡是系统具备高灵活性的重要特征之一，并分析了高比例可再生能源发电接入对系统运行灵活性的影响；接着，介绍灵活调节产品的基本概念、产品特点、定价机制和出清模型，并将其与现有的一些辅助服务进行比较；之后，通过2个算例直观展示灵活调节产品在提高电力系统运行灵活性方面的作用；最后，概述灵活调节产品的研究现状，并对未来灵活调节产品的研究进行展望。

关键词: 电力系统, 运行灵活性, 灵活调节产品（FRP）, 间歇性可再生能源发电, 系统净负荷

Abstract: With the ever-increasing penetration of intermittent renewable energy generation， the operation flexibility of a given power system is more and more demanded. To address the issue of insufficient upward and downward ramping capability in real-time dispatch， flexible ramping product （FRP） has been proposed and initially implemented by some independent system operators （ISOs） in the United States as a new market design. The main function of FRP is to explore flexible capability from dispatchable resources so as to meet potential upward and downward ramping requirements， and thus to enhance power system operation flexibility for effectively responding to various operation conditions. The basic concepts and related subjects of power system operation flexibility are first clarified， and it is pointed out that the ability to maintain the balance between power supply and power demand at all time scales under credible complex scenarios is one of the important characteristics of strong operation flexibility. Besides， the impacts of high penetration of intermittent renewable energy generation on power system operation flexibility are examined. FRP is then introduced with the focuses on basic concepts， main characteristics， pricing mechanism and clearing models， and comparisons with the existing ancillary services are made as well. Furthermore， two case studies are served for demonstrating the implementation of FRP in enhancing power system operation flexibility. Finally， the current research status of FRP is outlined， and prospects on FRP-related subjects to be studied presented.

Key words: power system, operation flexibility, flexible ramping product （FRP）, intermittent renewable energy generation, system net load
