论文摘要
当前的风险评估忽略了能源可用性本身的随机性质,从而导致操作过程中的潜在风险。本文提出了允许提供概率储备的通用储能(GES)的重新定义。针对四种典型类型的GE提供了具有外源和内源性不确定性(EXU&EDU)描述的数据驱动的统一模型(EXU&EDU)。此外,提出了风险指数来评估GES的忽视(EXU&EDU)的影响。 EXU和EDU之间的比较结果在分配系统中以日益投放限制的优化(CCO)(CCO)进行了说明,后者观察到更严重的风险,这表明系统操作员(SO)应采用新颖的EDU不确定性策略。
Current risk assessment ignores the stochastic nature of energy storage availability itself and thus lead to potential risk during operation. This paper proposes the redefinition of generic energy storage (GES) that is allowed to offer probabilistic reserve. A data-driven unified model with exogenous and endogenous uncertainty (EXU & EDU) description is presented for four typical types of GES. Moreover, risk indices are proposed to assess the impact of overlooking (EXU & EDU) of GES. Comparative results between EXU & EDU are illustrated in distribution system with day-ahead chance-constrained optimization (CCO) and more severe risks are observed for the latter, which indicate that system operator (SO) should adopt novel strategies for EDU uncertainty.
