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.
