随着间歇性分布式电源大量接入配电网,源荷双端不确定性加剧,增大了配电网安全运行的风险,因此提出了一种配电网风险评估与调控策略.首先,针对居民区、工业区、商业区分别进行风险评估,采用蒙特卡洛法计算各区域的风险值.其次,提出了区域安全裕度指标,用于评估各区域的风险调控能力.然后,根据区域安全裕度值的大小,分别进行区内、区间协同的风险调控.最后,采用CPS 62节点算例验证了所提风险调控策略的有效性.
Risk Assessment and Control Strategies for Intermittent Distributed Energy Resources Integration into Distribution Networks
As intermittent distributed energy resources are extensively integrated into distribution networks,the uncertainty on both the supply and demand sides exacerbates,thereby increasing the risk of secure operation of distribution networks.To address this issue,a risk assessment and control strategy for distribution networks is proposed.Firstly,risk assessments are conducted separately for residential,industrial,and commercial areas,employing the Monte Carlo method to calculate the risk values of each area.Secondly,a regional security margin indicator is proposed to evaluate the risk control capability of each area.Subsequently,based on the magnitude of the regional security margin values,the risk control is carried out collaboratively within and between regions.Finally,the effectiveness of the proposed risk control strategy is validated by a CPS62 node case study.
