摘要
合理利用用户侧蓄能环节可以提高电力系统的调峰能力,加强电力系统消纳间歇性可再生能源的能力。针对蓄热电锅炉在弃风电量消纳过程中的应用,围绕可消纳电量(总量),消纳功率(强度),消纳速度(速度)3个方面,涉及日前、日内小时级以及日内实时3个层面,建立了一套评估指标集。该评估指标集为蓄热电锅炉消纳指令的下发提供数据支撑,为运行控制人员实时掌握系统运行状态提供数据保障,是蓄热电锅炉消纳弃风电量的关键。通过介绍蓄热消纳系统的组成,对该评估体系的使用方法进行了说明,并使用案例仿真验证了该消纳能力评估指标集的有效性。
Peak-load regulation capability of power systems can be improved by the rational utilization of thermal storage systems at the customer-side,which can also promote the consumption of the renewable energy.A set of indicators,which considers the quantity,the intensity and the velocity of the potential power consumption,is proposed to direct the consumption of the abandoned wind power by distributed electric boilers with thermal storage(EBTS).The indicator set evaluate the consumption ability from three aspects,which includes day ahead level,hour level and real-time level.The indicator set not only provides data support for the instructions of the EBTS,but also provide the real-time operating state information of EBTS to operators.This paper introduce the thermal storage consumption system,and elaborate the application of the indicator set,of which effectiveness is validated through case studies.
