Embodiment 1

[0038] This embodiment provides an online scheduling assistant decision-making method based on massively parallel processing. The basis for dispatching auxiliary decision-making, and realizes online dispatching auxiliary decision-making for current fault warning. At the same time, the economy of decision-making is also taken into consideration. By dividing the corresponding adjustment gears and enumerating parallel calculation methods, the minimum control cost to ensure the stable operation of the system for the current fault is given. Such as figure 1 shown, refer to the following figure 1 Describe each step in detail:

[0039] Steps 11-12. Undertake the work of the dynamic safety assessment stage, collect and analyze the dynamic safety assessment results, and select the unstable operations that endanger the stable operation of the power system. This part of the function is completed by commonly used power system simulation calculation software, and the calculation data ...

Embodiment 2

[0054] Such as figure 2 As shown, this embodiment provides an online scheduling assistant decision-making device based on massively parallel processing, including a management node and a computing node.

[0055] The management node is used to collect and analyze the dynamic safety assessment results, and determine the instability operation according to the evaluation results; according to the trajectory information of each dynamic component of the instability operation, control the trajectory of the power system state quantity to each operating parameter Sensitivity calculation; adjust the adjustment limit of the component and the set adjustment step according to the obtained trajectory sensitivity information, form an adjustment plan, and send the adjustment plan to each computing node in the form of a calculation job; receive the calculation analysis returned by the computing node results, and make decisions on the power grid based on the calculation and analysis results. ...

Abstract

The invention discloses an online scheduling aid decision method and a system based on the large-scale parallel processing, solving the problem that the prior art can not fully utilize the running information of an electric system so as to influence the accuracy of a scheduling aid decision. The method comprises the following steps: determining instability operation according to an evaluated result; calculating track sensitivity of electric system state quantity to each running parameter according to the track information of each dynamic element of the instability operation; and making the decision for a grid according to the obtained track sensitivity information. A device comprises a managing node and a calculating node. The invention mainly provides an online scheduling aid decision calculating method, and in the method, the track sensitivity is taken as the calculation main body, and the parallel calculation technology is taken as the calculation manner to calculate the correlation of the adjustable quantity of a system and the danger quantity of the system for some one instability hazard damaging the electric system and obtain a prevention control scheme aiming at the fault on line.

Description

technical field [0001] The invention relates to a power grid technology, in particular to an online scheduling auxiliary decision-making method and system based on large-scale parallel processing. Background technique [0002] The power industry is the economic lifeline of the country, and the safety and stability of the power system are closely related to the construction and stability of the country. Compared with developed countries, in the past ten years, under the condition of relatively weak power grid structure and technical equipment, my country has strengthened power grid security management and implemented technical measures for power grid security and stability, and no major power outages have occurred. But generally speaking, my country's power grid is a weakly connected system, and the security of the power grid has not yet achieved long-term stability, and the security situation of power grid operation is still severe. In order to ensure the safe, stable and e...
