Methodology of Electricity Supplying of Critical Infrastructure in Crisis Situations

The paper focuses on the issues associated with the supply of electricity to critical infrastructure in crisis situations. In the introductory passages, the paper focuses on the methodology of selecting objects of critical infrastructure. Subsequently, attention is paid to selected aspects associated with the operation of electricity generation during a crisis situations. By using suitable types of production units (gas turbines), it is possible to gradually start island operation in the surrounding region, primarily for critical infrastructure facilities, whose main task is to protect the population. In the practical part, the paper focuses on the issues of stability of the island operation mode. The results of the case study show that for the switch-on plan it is necessary to take into account the dynamic characteristics of island operation by feeding the objects of critical infrastructure gradually after small electrical power steps.
