Problems solved by technology

In terms of the above-mentioned measures, the economy of power supply is difficult due to power generation constraints, which reduces the economic efficiency of power system operation, or cuts off large-capacity generators in the event of a failure, resulting in a decrease in the frequency of transitions, so large-scale failures such as wide-area power outages may occur influences

Abstract

The present invention relates to an apparatus for controlling an energy storage system (ESS) according to a transient stability state and a method thereof. An apparatus for controlling an ESS according to a transient stability state according to one embodiment of the present invention comprises: an input unit for inputting phase angle information from each power generator; a calculation unit for calculating a phase angle variations between each two power generators, using the input phase angle information of each power generator; a determination unit for determining a transient stability stateby comparing each of the calculated phase angle variations between each two power generators with a predetermined threshold; and a control unit for controlling an ESS, installed on the side of a power generation end, into a charging mode according to a determination result.

Description

technical field [0001] The present invention relates to a device and a method for controlling an ESS (Energy Storage System, energy storage system) according to a transient stable state, in particular, to a device and a method for controlling an ESS according to a transient stable state, by judging the power system The transient stability state of the ESS determines the output value of the charging mode of the ESS to control the output of the corresponding ESS, thereby improving the transient stability considering the disturbance of the power system. Background technique [0002] The so-called power system refers to a system that connects power generation stations, substations, and loads with transmission lines to meet electrical needs, and is formed from the generation of electricity to consumption. The power system described realizes the generation and consumption of electricity simultaneously, so a balance of demand and supply should be formed. Therefore, power systems r...
