摘要/Abstract

摘要：

智能电网中的电能存储系统能够在系统故障修复期间持续供电，以避免大面积停电．然而，电能存储系统的成本与其容量成正比．使用有限容量Petri网建立智能电网传输系统的模型．通过对模型性质的分析，文中提出一个计算电能存储系统最小容量的方案．该方案不仅避免了因为系统参数间的不协调所导致的大面积停电；还为故障期间避免大面积停电提供一个必要的约束条件；最后，对方案进行了验证．实验结果表明，该方案能有效避免大面积停电且电能存储系统的容量也得到优化．

Abstract:

The power storage systems in smart grids can continually supply electric power to avoid large area blackouts during fault repair periods. However, the costs of power storage systems are proportional to their capacity. In this paper, the models of power transmission systems are constructed by using finite capacity Petri nets. A scheme for computing the minimum capacity of power storage systems is proposed by analyzing the property of power transmission system models. This scheme can avoid large area blackouts caused by the incompatibility of system parameters. Moreover, it also proposes a constraint for large area blackout avoidance during fault repair periods. Finally, a case study is presented to verify the proposed scheme. The results show that the scheme can avoid large area blackouts and that the capacity of power storage systems are optimized.

Key words: Petri nets, supervisory controls, power storage systems, capacity optimization
