摘要
大规模新能源的安全高效消纳矛盾是构建新型电力系统过程中亟待解决的关键科学问题.由于新能源渗透率是制约新型电力系统调节能力和抗扰动性能的重要边界,准确评估新能源极限消纳能力对电力系统规划、运行与控制具有重要意义.该文对新能源消纳能力评估方法的国内外研究现状及发展趋势进行了全面述评.首先,诠释新能源消纳能力的基本概念和评估指标;基于新能源出力特点以及新型电力系统"源-网-荷"演化趋势,深入阐述制约新能源消纳能力的关键因素;为了应对新型电力系统在新能源高比例渗入过程中面临的共性问题与挑战,构建了新能源消纳能力评估的总体研究框架,从电力电量平衡、安全稳定约束和电能质量3方面对当前新能源消纳能力评估方法的国内外研究现状进行述评;最后,展望了未来该领域仍需重点研究的方向.
Abstract
The contradiction between security and efficient consumption of large-scale new energy is a key issue that needs to be solved in the new power system.Since the level of new energy penetration is an important boundary that restricts the regulation capability and anti-disturbance performance of the new power system,it is of great significance to accurately evaluate the maximum accommodation capability of new energy for the planning,operation,and control of power systems.This paper comprehensively reviews the research status and development trends of new energy accommodation capability evaluation methods both domestically and internationally.First,the basic concept and evaluation indices of new energy accommodation capability are interpreted.Based on the characteristics of new energy output and the evolution trend of"source-grid-load"in the power system,the key factors that restrict new energy accommodation are elaborated in depth.In order to cope with the common problems and challenges faced by the new power system during the high proportion of new energy penetration,the overall research framework of the new energy accommodation capability evaluation method is proposed.The current research status of the new energy accommodation capability evaluation methods is reviewed from the perspectives of power balance,security and stability constraints,as well as power quality.Finally,some potential research directions in this field in the future are prospected.
