摘要
受新能源“无稳定电力、有基础电量”的发电特性影响,西北地区电力电量平衡特性呈现新形态,电网同时面临腰荷时段的新能源消纳压力及早晚高峰的保供压力。基于高比例新能源电网实际运行数据及历史统计数据,分析了西北地区电力电量平衡的风险特性,梳理了国内外电力系统面向区域供需平衡的关键技术及配套市场机制,立足西北地区源网荷发展态势,提出了兼顾电力可靠供应和新能源高效消纳的西北电网电力电量平衡措施与建议。
Due to the high uncertainties of renewable energy,the power supply-demand balance state shows new features in Northwest power grid.The power grid faces big challenges in both renewable energy accommodation in low load period and reliable power supply in peak load period.This paper firstly evaluates the characteristics of power supply-demand imbalance risks in Northwest China,according to the actual operation data and historical statistical data.Then,the key technologies and supporting market mechanisms for regional power supply-demand balance in China and abroad are reviewed.Based on the development trend of grid-source-load in Northwest China,some measures and suggestions are proposed for power supply-demand balance in Northwest power grid to guarantee the reliable supply of electric power and efficient accommodation of renewable energy.
