Abstract

A dynamic stability assessment device is provided. The dynamic stability assessment device includes an energy management system (EMS); and a dynamic stability assessment system for dynamic stability assessment on a power system of the energy management system. The EMS includes a plurality of facility names with respect to a single facility, and processes to power system data based on any one of the plurality of facility names according to a state of the power system.

Claims

1. A dynamic stability assessment device comprising:

an energy management system (EMS); and

a dynamic stability assessment system for dynamic stability assessment on a power system of the energy management system,

wherein the EMS comprises;

an EMS DB that stores power system data for energy management,

a display unit configured to output a dynamic stability assessment result, and

a control unit configured to process the power system data stored in the EMS DB and to provide the processed power system data to the dynamic stability assessment system,

wherein the dynamic stability assessment system is configured to perform the dynamic stability assessment through the processed power system data,

wherein the control unit is further configured to generate a plurality of facility names with respect to a single facility and process the power system data based on a facility name among the plurality of facility names according to an operating condition of a current status of the power system,

wherein each of the plurality of facility names comprises a facility type, an equipment name, a node name, and an operation control scheme, and

wherein each of the facility type, the equipment name, and the node name of each of the plurality of facility names with respect to the single facility are the same among the plurality of facility names, and the operation control scheme of each of the plurality of facility names with respect to the single facility is different from each other among the plurality of facility names.

2. The dynamic stability assessment device according to claim 1, wherein a real-time data link program is used for data transmission and reception between the EMS and the dynamic stability assessment system.

3. The dynamic stability assessment device according to claim 2, wherein the real-time data link program uses a data format into which the plurality of facility names are inserted, for each facility.

4. The dynamic stability assessment device according to claim 1, wherein an operation facility name, and an operation control mode are added as an operation name for the operation control scheme.

5. The dynamic stability assessment device according to claim 1, wherein the dynamic stability assessment system performs dynamic stability assessment after an action according to the operation control scheme is taken.

6. A dynamic stability assessment method comprising:

providing, by an energy management system (EMS), power system data;

reflecting, by the dynamic stability assessment system, an operation control scheme by using the power system data provided from the EMS to perform a dynamic stability assessment operation;

providing, by the dynamic stability assessment system, an assessment result to the EMS;

outputting, by the EMS, the assessment result;

generating, by the EMS, a plurality of facility names with respect to a single facility; and

processing, by the EMS, the power system data based on a facility name among the plurality of facility names according to an operating condition of a current power system,

wherein each of the plurality of the facility names comprises a facility type, an equipment name, a node name, and the operation control scheme, and

wherein each of the facility type, the equipment name, and the node name of each of the plurality of facility names with respect to the single facility are the same among the plurality of facility names, and the operation control scheme of each of the plurality of facility names with respect to the single facility is different from each other among the plurality of facility names.

7. The dynamic stability assessment method according to claim 6, wherein the dynamic stability assessment operation is performed based on at least one pre-stored scenario.

8. The dynamic stability assessment method according to claim 6, further comprising receiving further power system data from the EMS, when it is difficult for the dynamic stability assessment system to determine dynamic stability.

9. The dynamic stability assessment method according to claim 6, wherein a real-time data link program is used for data transmission and reception between the EMS and the dynamic stability assessment system.

10. The dynamic stability assessment method according to claim 9, wherein the real-time data link program uses a data format into which the plurality of facility names are inserted for each facility.
