Optimization Method for Voltage Safety of DC Microgrid Considering Integrated Risks
摘要
Abstract
DC microgrid possesses notable advantages in integrating distributed energy resources and DC loads.However,under the scenarios considering the comprehensive risks caused by wind and solar output uncertainty and equipment failures,formulating optimal scheduling strategies to ensure voltage security poses significant challenges.To address this problem,this paper proposes a two-stage adaptive robust optimization scheduling method that incorporates voltage safety constraints.First,an equivalent circuit model of the DC microgrid is developed to characterize the mapping relationship between power variation and voltage fluctuation.An explicit formulation of voltage safety constraints is then constructed using the elastic net regression method.Furthermore,for the scenarios with comprehensive risks,a two-stage robust optimization model is developed to achieve coordinated scheduling combining pre-scheduling in the first stage with dynamic adjustment in the second stage,which aims to enhance the economic efficiency of the system while ensuring voltage safety.Case study results demonstrate that the proposed method can effectively balance the safety and economic performance of DC microgrid.关键词
