| 摘要: |
| 家庭能源管理系统是未来智能电网在配电侧发展的重要研究方向。以包含光伏发电、蓄电池储能和家庭负荷的家庭直流微电网系统为研究对象，研究了各个单元的基本控制策略，并提出了基于微网技术的家庭微网能量调度策略。系统的工作模式包括并网工作模式和离网工作模式，通过能量调度策略来维持系统功率平衡和直流电压稳定。在Matlab/Simulink下搭建了家庭直流微网系统并对该控制策略进行仿真验证。仿真结果表明，系统在并网运行模式和离网运行模式下均能保持直流侧电压稳定，验证了家庭能源管理系统的正确性和有效性。 |

| Abstract: |
| The home energy management system is one of the most important applications of future smart power grids. This paper takes home DC microgrid system which contains photovoltaic power generation system, battery energy storage system and home load as a study objective. It studies the basic control strategy of each unit, and proposes an energy scheduling policy for home microgrid based on microgrid technology. The system can operate not only in-grid mode but also in off-grid mode. The energy scheduling policy can balance the system power and stabilize the DC voltage. The home DC microgrid system is simulated using Matlab/Simulink to verify the proposed control strategy. Simulation results indicate that the DC voltage can be stabilized under both in-grid mode and off-grid mode, verifying the validity and effectiveness of home energy management system. |
