Embodiment Construction

[0037]Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0038] This embodiment takes IEEE standard 33 nodes as an example. In this power distribution system, a distributed photovoltaic power source with a size of 3MVA is connected to node 3, and a wind power generation with a grid-connected capacity of 2.5MVA is connected to node 5. The 16th node is connected to an electric vehicle charging and discharging station with a charging power of 0.6MVA and a discharging power of 0.58MVA.

[0039] like figure 1 As shown, taking the d...

Abstract

The invention discloses a method for assessing influence on a power distribution network from distributed power sources and electric cars. Under the situation that novel demand side resources such as various types of distributed power sources and various types of electric cars have access to the power distribution network, the influence on the power distribution network from grid-connected operation of distributed power sources and electric cars can be accessed rapidly and accurately considering the interactive influence factors between distributed power sources and electric cars, the operating state of the power distribution network can be controlled more conveniently and flexibly, and the method lays a foundation for coordinated control over distributed power sources and electric cars in a smart power distribution network in the future.

Description

technical field [0001] The invention relates to a method for evaluating the impact of a distributed power supply and an electric vehicle on a distribution network, belonging to the field of smart grids. Background technique [0002] In the modern smart distribution network, the access scale of distributed power sources and electric vehicles is getting larger and larger, and the access capacity of these new loads and power sources has affected the characteristics of the entire power system. The grid connection of distributed power generation and electric vehicles will mainly affect the power quality, system reliability, system protection and power market of the power grid. And how to evaluate the impact of distributed power supply and electric vehicle grid-connected operation on the distribution network, so as to intuitively measure the ability of the distribution network to accommodate distributed power supply and electric vehicle grid-connected, to facilitate direct, effici...
