Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0056] Such as figure 1 As shown, an online decision-making method for multi-area load shedding control taking into account the accident risk level,

[0057] Step 1, generation of power flow data: take the converged grid operation section data flow as the initial operating state S of the grid 0 , go to step 2;

[0058] Step 2, security and stability assessment: for S 0 , conduct security and stability quantitative assessment DSA, and get the weak mode set W of the power grid e and the margin η of the weak mode e.j , and set the load reduction decision-making measure set OPC to an empty set, and enter step 3;

[0059] Step 3, decision-making start judgment: if the weak pattern set W e Medi...

Abstract

The invention discloses a multi-region emergency load reduction collaborative decision-making method and system and a storage medium. On the basis of initial safety and stability evaluation, performance indexes of all control measures and accident risk levels of areas to which the control measures belong are comprehensively considered for layering, clustering and sorting, multiple control schemeswith sequentially increased adjustment amounts and active balance are generated, and a critical safety scheme is rapidly recognized based on a parallel computing platform. According to the invention,multi-region emergency load reduction online collaborative decision making considering the accident risk level can be carried out, a load reduction control scheme with lower accident risk level and higher cost performance is obtained, and the requirements of load reduction control on economy, timeliness, safety and risk level in a warning state, an emergency state or an extreme emergency state aremet.

Description

technical field [0001] The invention relates to a multi-area emergency load shedding collaborative decision-making method, system and storage medium, belonging to the technical field of electric power system automation. Background technique [0002] With the development of the economy, the total load of my country's power grid is increasing year by year. The State Council ordered the "Regulations on Emergency Response and Investigation and Handling of Electric Power Safety Accidents" hereinafter referred to as the "Regulations". According to the degree to which electric power safety accidents affect the safe and stable operation of the power system, accidents are divided into particularly serious accidents, major accidents, major accidents and general accidents, and According to the load level and region of the power grid, the power grid load reduction ratio, user power outage ratio and accident level judgment standards have been formulated respectively. The accident event i...
