摘要
电能路由器是未来能源互联网中的关键设备,其可靠性关系着未来配电网的安全可靠运行。配置冗余子模块可提升设备的可靠性,但同时会使成本增加。以目前主流电能路由器拓扑为基础,分析对比了设备不同冗余控制方式下的可靠性;引入成本-损失目标函数对冗余配置进行优化,研究了不同情况下目标函数最小值的求解,并以此得到可靠性与经济性最佳的冗余配置方案。最后通过对工程实例的分析计算,为子模块选型与冗余配置给出了建议,验证了所提方法的可行性与有效性。
Energy router is the key equipment in future energy internet; its reliability relates to safe and reliable operation of distribution network. With redundancy modules, reliability of the equipment is increased, so is the cost. For mainstream topology of energy router, reliability under different control methods is analyzed and compared, and an objective function is presented for optimal design. Solutions for minimum value of the function under different circumstances are discussed, and the best scheme for balance between reliability and economy is obtained. Finally, an engineering application is analyzed. Suggested model and number of sub-modules is given, and validity and feasibility of the proposed method is verified.
