摘　　要：通过能量路由器对传统配电台区进行柔性化改造,能够有效应对冲击性负荷与分布式电源接入台区所带来的影响。提出一种多端口能量路由器优化配置方法,能够合理配置能量路由器中储能单元容量,以使台区固定资产投资、设备电能损耗及负荷限幅损失构成的综合成本最小。首先,简要介绍了多端口能量路由器及其优势;然后,以配电台区投资运营综合成本最小为目标函数,建立了考虑储能寿命约束的多端口能量路由器的优化配置模型;最后,通过算例验证了多端口能量路由器在交直流多模式供电、源荷储高效互动与设备柔性增容方面的显著优势。The flexible transformation of the traditional distribution station area through the energy router can effectively deal with the impact of shock load and distributed power access to the station area. Therefore, this paper proposes a multi-port energy router optimization configuration method, which can reasonably configure the capacity of the energy storage unit in the energy router, so as to minimize the comprehensive cost of the fixed asset investment, equipment power loss and load limiting loss. Firstly, the paper briefly introduces the multi-port energy router and its advantages;Then, taking the comprehensive cost of investment and operation in the distribution station area as the objective function, the optimal configuration model of multi-port energy router considering the constraint of energy storage life is established;Finally, the significant advantages of multi-port energy router in AC/DC multi-mode power supply, efficient interaction between source load and storage and flexible capacity expansion of equipment are verified by numerical examples.
