城市办公楼光储系统控制策略分析及应用

Analysis and Application of Control Strategies for Photovoltaic-storage System in Urban Office Buildings

在“双碳”目标提出后,“光储直柔”技术逐渐成为建筑领域节能减碳、灵活用电的研究热点。为深入探讨城市办公楼能源利用的控制策略,提升可再生能源的利用率,该文以深圳市某办公楼的光储系统为研究对象,首先,对其微电网的运行工况进行建模;然后,构建光储系统的3种运行模式:简单模式、经济模式和节能模式,及与这3种运行模式对应的控制策略;最后,进行具体案例的分析对比。对比分析结果表明,提高光伏自用率有利于降低用电成本,提升光储系统的可调节性,对同类建筑的光储系统应用优化具有一定的参考价值。

After the proposal of the"dual carbon"goal,"photovoltaic-storage-DC-flexible"technology has gradually become a research hotspot in the field of energy conservation,carbon reduction,and flexible electricity use in the construction industry.To deeply explore the control strategies for energy utilization in urban office buildings and improve the utilization rate of renewable energy,this paper takes the photovoltaic-storage system of an office building in Shenzhen as the research object.Firstly,the operating conditions of its microgrid are modeled;Then,construct three operating modes of the photovoltaic-storage system:simple mode,economic mode,and energy-saving mode,and corresponding control strategies for these three operating modes;Finally,analyze and compare specific cases.The comparative analysis results show that improving the self use rate of photovoltaics is beneficial for reducing electricity costs,improving the adjustability of photovoltaic-storage systems,and has certain reference value for optimizing the application of photovoltaic-storage systems in similar buildings.
