Intelligent soft switch optimal configuration method considering renewable energy permeability

Abstract

The invention relates to an intelligent soft switch optimal configuration method considering renewable energy permeability. The method comprises the following steps: step 1, establishing an intelligent soft switch model; 2, establishing a hydrogen production and storage model, and regarding a hydrogen production and storage field as a load; 3, an integral double-feeder model is built, the double-feeder model is composed of two feeders, each feeder contains distributed power generation nodes and corresponding load nodes, each node can have multiple lines for power inflow and outflow, and only one of the two lines is connected to a power grid; 4, the position where the switch can be accessed is determined, the position where the switch can be accessed is between the distributed power generation field and the load of the other feeder line, and therefore the power Xi transmitted on the ith SOP line is obtained, and the power on each line is calculated in cooperation with the load power and the renewable power source power; and 5, determining the access position and the capacity of the required intelligent soft switch.

Description

technical field [0001] The invention relates to an intelligent soft switch optimization configuration method considering the penetration rate of renewable energy, and belongs to the field of planning and operation of DC distribution and consumption systems. Background technique [0002] In recent years, with the continuous development of the power grid and power electronics technology, on the power supply side, users' requirements for the economy of power consumption, power quality and power supply reliability have been continuously improved, and the shortcomings of traditional power grids such as fixed topology and limited control methods have become increasingly prominent. . At the same time, on the energy side, as the world's energy crisis and global warming become increasingly serious, renewable energy such as wind power, hydropower, and photovoltaics is the main way to replace traditional fossil energy on a large scale. As a result, intermittent renewable distributed e...
