Reactive configuration double-layer planning method for power distribution network containing distributed photovoltaics

[0055] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Figure 5 For the example structure of the distribution network in a certain area, the present invention provides a two-level planning method for reactive power configuration of a distributed photovoltaic distribution network, such as figure 1 , The method includes the following steps:

[0057] Step 1: Input the raw data of the power grid. In this example, photovoltaics are installed at nodes 10, 12, 14, 15, and 17, with a capacity of 500kW. According to the load and photovoltaic power, a typical calculation scenario is generated, mainly including sunny days, sunny days, and Cloudy days in spring working days, rainy days in spring working days, sunny days in spring holidays, cloudy days in spring holidays, rainy days in spring holidays, sunny days in summer working days, cloudy days in summer working days, rainy days in summer work
