基于配网安全、可靠、经济运行的分布式电源接入研究与实践

Research and Practice on Distributed Generation Integration Based on Safe, Reliable, and Economical Operation of Distribution Networks

  • 摘要: 随着大规模分布式电源的接入,选址定容通常由业主或投资者决策,分布式电源接入方案设计往往缺乏全局性考虑,对配电网的电压、电能质量、继电保护、规划和调度行等带来了诸多不利影响。现基于10 kV配电网稳定运行边界和实际运行状态,评估试点县域配电网各节点可接入的分布式电源容量裕度,进而为分布式电源和配电网的规划、建设提供指导。

     

    Abstract: With the large-scale integration of distributed generation, site selection and capacity determination are often made by project owners or investors, lacking a comprehensive and system-level perspective, which leads to adverse impacts on voltage, power supply quality, relay protection, planning and dispatching of the distribution network. This study, based on the operational boundaries and real-time operating conditions of 10 kV distribution networks, evaluates the capacity margins for distributed generation integration at each node of the pilot county-level distribution network. The results aim to provide technical guidance for the planning and construction of distributed generation and distribution networks.
