Prospective Options for the Republic of Moldova Power System Transport Network Development in Conditions of Parallel Operation with ENTSO - E

The work objective is to determine the optimal topology and strategic development directions for interstate and power system transport networks capable of ensuring electricity supply diversification, increasing the country's energy security, and successfully integrating it into the European electricity market. This goal is achieved through the following tasks: developing promising scenarios and creating corresponding computational models, using these models to calculate normal and enhanced modes, and analyzing operational parameters to assess the technical efficiency of the proposed options. A comparative analysis was carried out by modeling several alternative development scenarios, including the modernization of existing ones, as well as the construction of new 330 and 400 kV transmission lines, followed by an assessment of the technical efficiency of the proposed solutions. The most important result is the identification of promising scenarios for the Moldova energy system development, which, under current conditions, can ensure not only the fulfillment of ENTSO - E (European Network of Transmission System Operators for Electricity), but also minimize electricity losses and increase the safety factors for static stability. The options considered can lead to a reduced probability of system failures, greater flexibility in changing the power balance, and, consequently, increased reliability of energy supply. The significance of the obtained results lies in their potential to provide a basis for optimizing decision-making regarding the long-term development of Moldova's energy sector. The study's findings can also be used for capital investment planning and the development of long-term development programs in the energy sector, enabling the national energy system to function effectively within the European energy interconnection, promoting sustainable development and increasing energy independence.
