中文摘要:
      储能技术的快速发展为电网提供了新型的优质调频资源。本文针对储能资源响应速度快、跟踪精度高、调节方向易改变及有限的容量等特点展开了其参与电网调频的控制策略研究:首先,建立了区域电网AGC及包含储能SOC的储能系统仿真模型;然后,综合考虑储能资源与常规电源的发电特性,提出了计及储能SOC的快慢速调频资源协调控制策略;最后,搭建了四种不同的仿真场景,通过仿真试验对本文提出的控制策略的有效性进行了验证。#$NL关键词:储能系统; 仿真模型; 自动发电控制; 调频#$NL中图分类号:TM712
英文摘要:
      The energy storage technology has been promising as an auxiliary resource for power system frequency regulation. Energy storage system (ESS) has advantages of fast response speed, high following precision and easy-changing adjust direction, which has disadvantage of limit capacity, either. Considering the characteristics of ESS, control strategy of ESS participating in AGC is studied in this paper, firstly, power grid AGC system model and ESS model including state-of-charging(SOC) is established; then, with comprehensively considering the characteristics of ESS and conventional power resources, a coordination strategy between fast and slow regulation sources is proposed; finally, three different scenarios is designed, and the efficiency of the proposed strategy is demonstrated through the sets of simulation tests.
