Abstract

The invention discloses a trend calculating method of a multi-area interconnection power system and a system thereof and relates to the power grid operation management monitoring technology field. By using the method and the system of the invention, countermeasures can be beforehand or timely provided for a potential problem existing in the multi-area interconnection power system. The trend calculating method of the multi-area interconnection power system comprises the following steps of step S100, determining an analysis duration T in which the multi-area interconnection power system is analyzed; dividing the analysis duration T into n time periods, wherein the n is greater than or equal to 2; step S200, successively calculating trend distribution of the multi-area interconnection power system from a first time period to a nth time period; and step S300, outputting the trend distribution of the multi-area interconnection power system from the first time period to the nth time period. The trend calculating method of the multi-area interconnection power system provided in the invention is used for calculating the trend distribution of the multi-area interconnection power system in each time period.

Description

Technical field [0001] The invention relates to the technical field of power grid operation management and monitoring, in particular to a power flow calculation method and system for a multi-region interconnected power system. Background technique [0002] At present, the construction of my country's power grid is developing at a high speed. Moreover, when constructing the power grid, ultra-high voltage transmission technology, AC / DC hybrid technology, etc. have been introduced, thus making my country's power grid a multi-regional interconnected power system. Because the network structure of the multi-area interconnected power system is complex and changeable, it is of great significance to formulate the operation mode of the multi-area interconnected power system and check the safety of dispatching for the stable and safe operation of the multi-area interconnected power system. Usually, the staff use power flow calculation to formulate the operation mode of the multi-area interc...
