智能电网引领智能家居及能源消费革新

Smart grid leads the journey to innovative smart home and energy consumption patterns

随着智能电网技术的发展,分布式电源的接入,家庭能源的供需发生了重大变化,传统的家庭能源消费模式将产生重大变革,基于此,从智能家居能源的生产、消费及管理三个方面进行了探讨。在家庭能源利用方面,提出了家庭微电网交流、直流及交直流混合供电模式,给出了家庭能源控制中心的控制方案来实现家庭微网的"即插即用"。在能源消费方面,通过对比不同的电能量计量模式,为达到精细化的需求侧管理,提出了基于网络数据的计量,即网络计量,给出了其在智能家居中的应用方案。在家庭能源管理方面,总结了家庭能效管理的新特征,阐述了一种智能家庭能效管理"云+端"架构模式,在此模式下,真正实现了泛在网络式的家庭能效管理。智能家居能源消费模式的革新对分布式电源柔性接入,优化家庭电能使用及负荷管理,提高用电效率,降低用电成本,具有十分重要的意义。

With the development of smart-grid technology and the access of distributed generation （DG）, the supply and demand of home energy will be greatly changed as well as traditional home energy consumption pattern. This paper discusses the major changes in home energy consumption pattern from three aspects： energy production, measurement and management. In the first part, it proposes three power supply architectures for the home micro-grid utilization, which are AC power supply, hybrid of DC and AC supply, and DC power supply. It points out that the control mode., of home energy control center is the most important factor in enabling home micro-grid ＂plug-and-play＂. The second part focuses on the electricity energy measurement. By comparing different electricity metering methods, it provides a new measurement mode based on network data, i.e. network measurement, to enhance demand-side management and gives its application scheme in smart home. In the third part, combining the new features of home energy efficiency management, it designs one new ＂cloud ＋ terminal＂ energy service architecture to enable ubiquitous management of smart home energy efficiency, and also analyzes the impact of tile new mode on the flexible access of DG. The new smart home energy consumption innovation optimizes home energy use and load management, improves home energy efficiency and reduces electricity cost.
