Embodiment Construction

[0021] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0022] In the evolution process of the power system, through continuous construction, its power generation capacity, load and grid structure are constantly changing. In the initial stage of the power system, the adaptability of its components is different, and in order to give full play to the capabilities of the components, people often make them bear as much load as possible. Therefore, in this invention, the method we consider is to make the elements with the least adaptability continuously mutate to observe the evolution of the system.

[0023] The patent of the present invention provides a method for judging the self-organized critical state of the power system by defining the index of the adaptability of the power system components and examining the overall properties of the system.

Abstract

The invention relates to a self-organization critical state judgment method of a power system. The self-organization critical state judgment method comprises: step 10, utilizing a direct current tide model to obtain initial loads of elements; step 20, endowing initial adaptive values for the elements; step 30, utilizing the initial loads and the initial adaptive values to calculate ultimate loads borne by the elements; step 40, enabling the element with lowest adaptability to be continuously varied so as to observe the system evolution situation and judge whether the system is in a self-organization critical state. The self-organization critical state judgment method enables the element with lowest adaptability to be continuously varied so as to judge the self-organization critical state of the power system from the aspect of global property of the system and meets the actual situation of the power system.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for judging a self-organized critical state of a power system. Background technique [0002] The power system is a complex system, and the blackouts that occur during its operation are due to the system being in a self-organized critical state, and the disturbance triggers a chain reaction and causes a catastrophe. The current method to describe the self-organized critical state of the power system is mainly to judge whether the scale of outages (such as the load lost by outages) and the frequency of outages satisfy the power law feature. This method needs to count the size of each power outage accident, requires a large amount of power outage data, the calculation and simulation are more complicated, and the overall nature of the power system is not considered. Contents of the invention [0003] The purpose of the present invention is to provide a method for judging the...
