摘要
大规模分布式电源(distributed generation,DG)接入电网给电力系统传统集中式调控带来困难。为进一步提升分布式电源集群(distributed generation cluster,DGC)灵活性分布式调控,提出一种考虑DGC供需平衡及响应速度的集群划分方法。首先进行了集群爬坡灵活性分析,提出了功率分配策略以满足调频灵活性需求;接着,提出了DGC供需平衡指标以及响应速度指标,得到了集群划分方法;最后,基于IEEE 33节点算例验证了所提方法的有效性。
The large-scale connection of distributed generation(DG)to the power grid brings about significant difficulties to the conventional centralized regulation of the power system.In order to improve the regulation flexibility of distributed generation cluster(DGC),a cluster partition method is proposed considering the supply-demand balance and response speed of DGC.Firstly,the cluster climbing flexibility is analyzed and a power allocation strategy is proposed to meet the demand of FM flexibility.Then,the DGC supply and demand balance index and response speed index are proposed,and the cluster partition method is obtained.Finally,an IEEE 33 node example is given to verify the effectiveness of the proposed method.
