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。
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.
