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 control unit configured to process the power system data stored in the EMS DB to power system data based on a facility name that comprises an operation control scheme, to provide the processed power system data to the dynamic stability assessment system, and to enable an assessment result to be stored and output, the assessment result reflecting the operation control scheme that is received from the dynamic stability assessment system, and

the EMS comprises a plurality of facility names with respect to a single facility, and is configured to process to power system data based on any one of the plurality of facility names according to a state of the power system.

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 a unique facility name is inserted, for each facility.

4. The dynamic stability assessment device according to claim 3, wherein the unique facility name comprises a facility type, an equipment name, and a node name.

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

6. 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.

7. The dynamic stability assessment device according to claim 1, wherein the dynamic stability assessment system applies, to at least one pre-stored scenario, power system data based on a facility name that comprises an operation control scheme input from the EMS, to perform an assessment operation.

8. A dynamic stability assessment method comprising:

providing, by an energy management system (EMS), power system data based on a facility name that comprises an operation control scheme;

reflecting, by the dynamic stability assessment system, the operation control scheme by using the power system data based on the facility name to reflect the operation control scheme to perform an dynamic stability assessment operation;

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

storing and outputting, by the EMS, the assessment result,

wherein the EMS comprises a plurality of facility names with respect to a single facility, and is configured to process to power system data based on any one of the plurality of facility names according to a state of the power system.

9. The dynamic stability assessment method according to claim 8, wherein the dynamic stability assessment operation is performed based on at least one pre-stored scenario.

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

11. The dynamic stability assessment method according to claim 8, wherein a real-time data link program is used for data transmission and reception between the EMS and the dynamic stability assessment system.

12. The dynamic stability assessment method according to claim 11, wherein the real-time data link program uses a data format into which a unique facility name is inserted for each facility.

13. The dynamic stability assessment method according to claim 12, wherein the unique facility name comprises a facility type, an equipment name, and a node name.
