光储直柔——助力实现零碳电力的新型建筑配电系统

PSDF(photovoltaic,storage,DC,flexible)——A new type of building power distribution system for zero carbon power system

介绍了光储直柔建筑配电系统的基本概念。"光"即建筑光伏,"储"是建筑内分布式蓄电及利用邻近停车场电动汽车的电池资源,"直"指建筑内部采用直流供电,"柔"则是光储直柔的目的,即实现柔性用电,使其成为电网的柔性负载或虚拟灵活电源。介绍了光储直柔配电系统的架构、调节策略、可实现的功率调节范围和与电网相互协调的方式。指出未来新型电力系统的目标是建立以风电、光电为主要电源的零碳电力系统,建筑光储直柔配电系统可解决发展风电、光电中的两大瓶颈问题:安装空间和有效消纳,从而需要与风电、光电装机容量的增长及电动汽车总量的增长同步发展和增长。

Presents the basic concept of the PSDF(photovoltaic, storage, DC, flexible) building power distribution system, where P is the building photovoltaic, S is the distributed power storage in the building and the use of battery resources from electric vehicles in the neighboring parking lot, D refers to the use of DC power supply system inside buildings, and F is the purpose of the PSDF system, to achieve flexible power demand, so that the building becomes a flexible load or to say a flexible virtual power plant. Describes the framework, the regulation strategy, the achievable capacity range and the way of mutual coordination with the grid of the PSDF system. Points out that the goal of the new power system in the future is to establish a zero carbon power system with wind power and photoelectronic power as the main power supply. The PSDF distribution system can solve the two bottleneck problems in the development of wind power and photoelectronic power: installation space and effective consumption. Therefore, the PSDF system needs to develop and grow synchronously with the growth of installed wind and photovoltaic power and the total amount of electric vehicles.
