Description

technical field [0001] The present invention relates to the field of distribution network, and relates to the calculation of the absorption capacity of distributed photovoltaic power generation, in particular to a calculation system for the maximum absorption capacity of distributed photovoltaic power generation based on active distribution network. Background technique [0002] Environmental pollution and energy shortage have become century-old problems in modern civilized society. Under this background, the use of distributed generation (DG) and renewable energy has been more and more widely developed. As the most abundant form of power generation in new energy sources that is not subject to geographical restrictions, photovoltaic power generation has been used more and more. As more and more distributed photovoltaics are connected to the distribution network, people pay more and more attention to the ability of the distribution network to accommodate them. Distributed ph...

Problems solved by technology

The above literature has conducted some research on the access capacity of DG access to the distribution network, but there is not much consideration for the uncertainty of distributed photovoltaic output and load, and only photovoltaic power generation is considered as a constant output.

And they do not consider the consumption capacity of distributed photovoltaics in the active distribution network
