为准确评估大型城市电网对分布式光伏的承载能力,该文在开展电网运行特性、电源装机构成、短路电流、电能质量、电压偏差及损耗和继电保护等6方面影响因素分析的基础上,提出考虑大型城市电网特性的分布式光伏承载力计算评估方法,并以大型城市电网为例,验证其可行性和实用性。算例结果表明,该方法能精准评估出电网10~220 kV母线可新增分布式光伏接入容量,为分布式光伏接入大型城市电网的规划、建设、运行分析提供有力指导。
Abstract
In order to accurately evaluate the carrying capacity of power grid to distributed photovoltaic power station, based on the analysis of six influencing factors, including the power grid operation characteristics, power supply installation composition, short-circuit current, power quality, voltage deviation and loss, relay protection. the calculation and evaluation method of distributed photovoltaic carrying capacity was put forward considering the characteristics of large-scale urban power grid. And then an example of the large-scale urban power grid. And then taking the large-scale urban power gird as an example, the feasibility and practicability are verified. The example results show that this method can accurately evaluate the new distributed photovoltaic carrying capacity of 10 kV to 220 kV bus of power grid, and also provide the guidance for the planning, construction and operation analysis of distributed photovoltaic access to large urban power grid.
