Analysis of the Conditions for Energy Independence for the Electric Power System of Serbia with Optimized Structure and Spatial Allocation of RES

Starting from the imbalance power profile in the completely decarbonized electric power system (EPS) of Serbia with optimal structure and spatial allocation of RES which minimizes EPS flexibility requirements, the conditions under which this EPS could achieve a certain degree of energy independence with the minimal total available cross-border interconnection capacity are investigated. The relationship between the total energy capacity of electrical energy storage systems (EESS), the total installed power of EESS, the degree of EPS energy independence and the required total available cross-border interconnection capacity are analyzed.
