新型电力系统建设之水电功能定位和参与调频与备用问题探讨
Functional Positioning of Hydropower and Its Participation in Frequency Regulation and Reserve Services in the Construction of the New Power System:Issues and Discussions
摘要
Abstract
Constructing a new power system dominated by renewable energy is a complex systemic challenge.Particularly with the large-scale development of renewable energy and the orderly phase-out of traditional coal power,the lack of system rotational inertia,diminished frequency regulation capability,and insufficient reserve capacity will become major threats to the safe and stable operation of future power system.Consequently,ensuring adequate supply of system rotational inertia,frequency regulation capability,and reserve capacity will inevitably become a paramount issue.Guided by the principle of"Establishing the new before phasing out the old",this paper analyzes the demand for rotational inertia,frequency regulation and reserves during different construction stages of the new power system,examines the characteristics of various power sources(including hydropower and thermal power)in providing rotational inertia and participating in frequency regulation and reserves,and assesses their adaptability to system requirements.Focusing on hydropower(including pumped storage,hereafter referred to as hydropower),the paper explores its new functional positioning,analyzes existing problems in current design,operation and relevant regulations/specifications,and proposes recommendations concerning design philosophy,technical standards and policy support.This discussion aims to stimulate further thought and consensus,seeking agreement on implementation pathways such as expanding hydropower installed capacity and optimizing its operational modes.The ultimate goal is to achieve the timely and rational establishment of sufficient hydropower-based rotational inertia and frequency regulation/reserve capabilities.关键词
