摘要
光伏储能发电系统快速发展导致光伏发电渗透率迅速上升,逐渐改变了传统配电网结构和运行方式。基于潮流计算分析,提出一种计及无功功率损耗的分布式光伏储能发电系统并网功率损耗模型。根据配电网最优运行状态进行功率损耗功率模型寻优分析,优化光伏储能发电系统注入配电网节点的功率,改善分布式光伏储能发电系统并网性能。以某单电源配电网为例进行仿真分析,对比不同功率损耗常数下节点电压波动、系统功率损耗,验证文中功率损耗模型的正确性与可行性。
With the rapid development of Photovoltaic Generation with Energy Storage, the photovoltaie penetration rate is rising rapidly. This paper presents a kind of power losses model of distributed photovoltaic energy storage system connected to network accounting of reactive power based on the load flow analysis of distributed network operation. According to the analysis of optimal operating state of the distribution network power losses model, optimize of the power of photovoltaic power generation system storage and improve storage distributed photovoltaic power generation system and network performance. Taking a single power distribution circuit as an example to analysis the power losses model, compare the results of voltage fluctuation/power losses in different operation states under the index of the power losses. It verifies the correctness and feasibility of the power losses model.
