Energy security aspects related to the National Power Grid

Abstract

National Power Grid is an important element within the National Power System, having in its composition critical infrastructures of national importance without which the national economy could not operate, and its non-operation, totally or partially (black/brown-out), generates energy insecurity, negative factor with devastating and catastrophic effects on industrial, economic and national security. Due to the fact that National Power Grid is of national strategic importance, it has to be assessed and monitored permanently in terms of security risks, in order to identify vulnerabilities, and this need for assessment also comes from the European perspective because Romania is interconnected to ENTSO-E (European Network of Transmission System Operators) which interconnects various power overhead lines from North to South, from West to East, or even with Africa and Asia. In order to secure the National Power Grid, the authors have set out in this paper to identify possible internal or external vulnerabilities and what impact they have on the National Power Grid and National Power System. By knowing the vulnerabilities, one can automatically identify the dangers and threats to which it is subjected and engaged, being able to develop national/European measures or strategies for the protection and security of the critical infrastructures related to. For this reason, it is considered that the identification of vulnerabilities must become a pressing issue of national, and European energy security and be a useful tool for authorities to develop a energy strategy (short – long term) for the proper functioning of the National Power Grid and the national economy, because all sectors of the economy depend on electricity. The identified vulnerabilities are eliminated by National Energy Strategy 2021 – 2036 (short, medium,and long term) proposed by the authors, with the aim of increasing energy and national security.
