Abstract

The invention provides a distributed photovoltaic access method based on cluster analysis. The method comprises the following steps: S100, evaluating the total amount of distributed photovoltaic resources through satellite aerial photographing and site investigations, and dividing roofs into photovoltaic roofs and ordinary roofs; S200, creating a distributed photovoltaic roof scale map; S300, carrying out the cluster analysis according to the distributed photovoltaic roof scale map to initially determine positions of distributed photovoltaic socket points; S400, carrying out full-load distributed photovoltaic access to the distributed photovoltaic socket points, judging whether effects on the voltage quality, harmonic waves, short-circuit currents and the load rate of a power grid meet indicator requirements or not, and carrying out the cluster analysis again to optimize the positions of the distributed photovoltaic socket points for the distributed photovoltaic access if the effects do not meet the indicator requirements; S500, finally determining the positions of the distributed photovoltaic socket points according to factors such as an actual environment and geographical assetsof a site; and S600, carrying out the distributed photovoltaic access through the distributed photovoltaic socket points, so that the distributed photovoltaic access is safe and reliable.

Description

technical field [0001] The invention relates to a distributed photovoltaic access method, in particular to a distributed photovoltaic access method based on cluster analysis. Background technique [0002] As a typical clean and renewable resource, distributed photovoltaic has developed rapidly in recent years due to its rich resources and wide application range. For industrial parks with good roofs, distributed photovoltaic power generation is favored by investors. However, large-scale distributed photovoltaic power generation access will have a greater impact on power grid planning, construction, operation and maintenance, and safe and stable operation. The quality of the power grid exceeds the allowable deviation range and the problem of unbalanced line load, so as to promote the friendly development of distributed photovoltaic access to the power grid is the key to current research. Contents of the invention [0003] The purpose of the present invention is to provide ...
