摘要

为了提高分布式光伏电源的控制能力,提出了一种基于储能配置模式和随机事件的分布式光伏电源消耗方法。构建了分布式光伏电源控制的网络化约束参数分析模型。基于光储直接柔性模式,构建了分布式光伏电源控制的交直流电压等级控制模型。在直流混合配电网运行模式下,利用需求响应跟踪识别方法分析了分布式太阳能供电负荷的不确定性特征参数,并结合规划的储能容量参数,估算了分布式太阳能供电负荷和光伏输出功率。通过配置最优储能容量,调整微电网功率分布,并综合分析储能配置模式中的不确定因素和随机事件,实现了分布式光伏辅助用电的设计。实验结果表明,采用该方法的分布式光伏消纳控制对负荷要求较低,能有效降低互联线路的交换功率,提高光伏储能系统的配置规模、系统可靠性和经济性。

Distributed photovoltaic supportability consumption method considering energy storage configuration mode and random events
In order to improve the control capability of distributed photovoltaic support, a distributed photovoltaic support consumption method based on energy storage configuration mode and random events is proposed. A networked and constrained parameter analysis model for distributed photovoltaic power supply control was constructed. Based on the direct flexible mode of optical storage, an AC/DC voltage level control model for distributed solar power supply control was constructed. In the operation mode of DC hybrid distribution network, the demand response tracking identification method was used to analyze the uncertain characteristic parameters of distributed solar power supply load, and combined with the planned energy storage capacity parameters, the distributed solar power supply load and photovoltaic output were estimated. By configuring the optimal energy storage capacity, adjusting the power distribution of the microgrid, and integrating the analysis of uncertain factors and random events in the energy storage configuration mode, the design of distributed photovoltaic support consumption has been achieved. The experimental results show that the distributed photovoltaic absorption control using this method has lower load requirements, can effectively reduce the exchange power of the interconnection line, and improve the configuration scale, system reliability, and economy of the photovoltaic energy storage system.
