摘要
为了实现分布式电源接入及对电能进行有效管理,将具备高度灵活的功率控制及信息交互功能的能量路由器应用于低压配电网,使得源-网-荷-储能够一体化低碳运行,从而提升负荷调节能力与新能源消纳水平,保障电力系统稳定运行。因此,设计了一种面向低压配电网应用的户用型能量路由器,根据各端口应用对象特性,对其拓扑结构及功率协调控制策略进行研究,为电能生产和消费提供可靠的能源管理策略。最后,通过仿真验证的方法,建立MATLAB/Simulink仿真模型对其功率协调控制策略进行仿真验证。仿真结果表明:所提出的多端口能量路由器功率协调控制策略能够实现多种运行模式下不同端口之间的功率互济和系统功率平衡控制,在能源管理方面具有较高的灵活性、稳定性和可靠性。
For the access of distributed power sources and the effective management of electric energy,energy routers with highly flexible power control and information interaction functions were applied to low-voltage distribution networks to achieve integrated operation of source-network-load-storage,thereby improving load regulation capabilities and new energy consumption levels,and ensuring the stable operation of the power system.Therefore,A household energy router for low-voltage distribution network application was designed,and its topology and power coordination control strategy were studied based on the characteristics of each port application object to provide a reliable energy management strategy for power production and consumption.Finally,a simulation model based on MATLAB/Simulink was established to verify its power coordination control strategy.The simulation results show that the proposed multi-port energy router power coordination control strategy can achieve power reciprocity and system power balance control between different ports under various operating modes,and has high flexibility,stability and reliability in energy management.
