Problems solved by technology

However, to implement this method, the installed capacity of distributed photovoltaics needs to be increased one by one through linear increments. When the installed capacity of distributed photovoltaics is low, a large number of power flow calculations are still required, which wastes calculation time.

Abstract

The invention provides a distributed photovoltaic absorption capability determination method and device. The method comprises the following steps: determining a plurality of distributed photovoltaic installation scenes according to node positions and node number in a power distribution network; for each photovoltaic installation scene, performing binary search according to a preset simulation initial interval and a preset simulation initial value of the distributed photovoltaic, and determining the total installation capacity of the distributed photovoltaic and the maximum voltage of the power distribution network in the photovoltaic installation scene; and for each photovoltaic installation scene, determining the distributed photovoltaic absorption capability in the photovoltaic installation scene according to the total installation capacity and the maximum voltage of the power distribution network. The photovoltaic absorption capability in different distributed photovoltaic installation scenes can be efficiently determined.

Description

technical field [0001] This application relates to the field of electric energy, specifically a method and device for determining the capacity of distributed photovoltaics. Background technique [0002] In recent years, clean energy power generation systems represented by solar photovoltaic power generation systems have developed rapidly around the world due to their clean, efficient, flexible and controllable advantages. [0003] At present, distributed photovoltaics are mostly connected to the grid through medium and low-voltage distribution networks. Before distributed photovoltaics are connected to the distribution network on a large scale, it is necessary to make a reasonable assessment of the consumption capacity of the distribution network. At present, the methods for evaluating the accommodative capacity of distribution network mainly include three categories: heuristic method, random scene simulation method and mathematical optimization method. Among them, the rand...
