The objective of this Study is creation of the defense plan of the Montenegrin power system. Focus of the defense plan is to analyze less probable and widespread disturbances, that can totally or partially endanger power system integrity and to define precise remedial actions in order to minimize their consequences.
The main activities within this defense plan in accordance with the latest ENTSO-E standards (ENTSO-E Policy 5 v3.0 and Network Code on Emergency and Restoration) are the following:
- Overview of present state related to defense plan development
- OTDF analyses and determination of observability area
- Steady state security assessment and determination of preventive and remedial actions
- Voltage stability assessment (voltage profiles, PV and QV analyses)
- Frequency stability assessment (under-frequency load shedding plan)
- Transient stability assessment (transient stability margin, critical clearing time)
- Small-signal stability assessment (modal analyses, small-signal stability margin, damping ratio)
Type of services provided:
- Present state analyses (compatibility of the existing defense plan with ENTSO-E Policy, relay protection settings, generator, turbine governor and excitation system models, functionality of existing under frequency load shedding plan, load shedding procedures, description of critical network conditions from the past)
- Load flow analyses
- Voltage profile analyses
- Steady-state security assessment
- Voltage stability assessment
- Frequency stability assessment
- Transient stability assessment
- Small signal stability assessment
