Complete blackout of Montenegrin electric power system considers outage of all generation capacities in Montenegro, absence of voltage in all facilities and stopping the electricity delivery to all end users. Each TSO has to prepare in advance and update regularly a restoration plan. After TSO proclaims partial or complete blackout of electric power system, all procedures related to the normal operation are suspended and all following actions are executed by instructions issued by TSO in line with the restoration plan. In that sense, TSO has the obligation to cover in detail general strategy for power system restoration as part of the plan for system restoration, which defines: the supply restoration priorities, available capacities for restoration of normal operation state and instructions to DSOs, electricity producers, as well as to other users, who must comply with them.

Objectives of this study are:

  • to define provisions of black start capability of generation units required for restoration of Montenegrin EPS;
  • creation of complete step by step reenergisation procedure allowing the progressive restoration back to normal system state;
  • verification of the reenergisation procedure by dynamic stability calculations in the critical phases of the restoration process;
  • creation of detailed operational handbook for all transmission system users involved in the restoration process.

Type of services provided:

  • Analyses of black start capabilities of generation units
  • Analyses of demand characteristics (maximum allowed duration of voltage interruption, under-frequency and under-voltage protection settings etc.)
  • Voltage stability and reactive power control analyses
  • Dynamic stability analyses
