摘要: 与传统交流供电建筑相比，全直流供电建筑在安全、经济和电能质量优化等方面具有较大的优势。研究全直流建筑储能最优运行策略，主要目的在于通过建筑全直流配电/用电，协同调用建筑内部储能合理充放电，对城市电力负荷日用电波动带来的峰谷差问题进行充分调整和优化。基于以上概念，对某接入多种新能源设备的新型全直流供电建筑的逐时发电、逐时能耗等进行模拟仿真，获取多种设备的发电、储能与用电曲线，建立供电数学模型。对恒功率电网取电、最优电价取电以及需求侧响应取电等方式进行相应运行策略优化，并得到运行策略方案。

Abstract: Compared with traditional AC power supply buildings, the All-DC power supply buildings have great advantages in terms of safety, economy and power quality optimization. Studying the optimal operation strategy of the All-DC building’s energy storage, the main purpose is to coordinate the charging and discharging of the internal energy storage of the building through the construction of the All-DC power distribution/electricity, and the peak-to-valley difference caused by the fluctuation of urban power load daily electricity consumption could be fully adjusted and optimized. Based on the above concepts, a new type of the All-DC power supply building with a variety of new energy equipment, time-of-day power generation, time-consuming energy consumption, etc., simulation, acquisition of power generation, energy storage and power consumption curves of a variety of equipment, establish power supply mathematics model. The operation strategy is optimized for the power supply of the constant power grid, the optimal power price and the demand side power take-off, and the operation strategy is obtained.
