NATIONAL SECURITY OF SUPPLY UNDER THE CONDITIONS OF PARTIAL TRANSITION OF THE POWER PRODUCTION TO VARIABLE RENEWABLE ENERGY SOURCES

The transition of the power system is an extremely complex and demanding process, which, if not adequately planned, can have a negative impact on the country’s energy security, endangering the highest national interests. In Europe today we are witnessing both well-planned energy transition processes, but also very poorly planned processes, which are practically unfeasible due to unrealistic expectations, and also incredibly expensive for the entire economy of that country. We have the opportunity to learn from good examples in Europe, but also from the mistakes of those unsuccessful examples. Only by looking at the problem from the point of view of the entire power system, without neglecting any of its segments, can we arrive at an optimal model of transition, which as such is suitable for our national system and the preservation of national interests. In this paper, we will focus on the security of supply parameter as one of the key identified parameters important for maintaining the performance of the power system at a satisfactory level in conditions of partial transition to variable RES.
