摘要:

针对自治型微电网(简称微网)群及其子微网能够离网运行,且能在极端条件下保持稳定运行的特点,分析了微网群和子微网中累计的不平衡能量在子微网最大允许连续离网运行时间、微网群最大允许连续离网运行时间、极端条件下系统期望稳定运行时间下的变化特性。考虑能量型储能系统补充最大能量缺额和吸收最大的过剩能量、功率型储能系统平抑最大功率波动,提出了微网群主储能系统和子微网储能系统中不同类型储能系统的容量配置方法。对于给定的最大允许连续离网运行时间和极端条件下系统期望稳定运行时间指标,所述方法可计算微网群最小的储能系统容量,

Abstract:

In view of the autonomous multi-microgrid(MMG)and its submicrogrid capability of off-grid operation plus steady operation in extreme conditions,an analysis is made of the characteristics of variation of accumulated unbalanced power in the MMG and submicrogrid with time parameters,including submicrogrid maximum allowable off-grid operation time,MMG maximum allowable off-grid operation time and expected maximum operation time with failure of submicrogrid and MMG.In order to ensure that the energy-type storage can compensate for the maximum insufficient energy and absorb the maximum surplus energy and the power-type storage can inhibit the maximum power fluctuation in the system,a capacity configuring method for the energy storing and power storing for MMG is proposed.For the given index of maximum allowable off-grid operation time and expected maximum operation time with failure of microgrid and MMG,the method can calculate the minimum size of composite energy storage systems(CESS)without massive time-domain simulation.Simple and convenient to use,the method has been used to improve the stability of MMG located at Weizhou island in Guangxi province.It is proved by calculating the load power loss probability that the capacity configuration can meet the systems requirement for reliability.
