Shaping the Future Croatian Distribution Network with the Ten-Year Network Development Plan

Abstract

The article “Shaping the Future Croatian Distribution Network with the Ten-Year Network Development Plan” deals with long term planning of Croatian power distribution systems. The Distribution system operator adopts and publishes an annual update to the ten-year distribution network development plan (TYNDP), which provides budgetary and economic analyses for the projected capital investments and establishes a list of priority areas in need of infrastructure upgrades.In the paper it is stressed out that the three main goals of the Ten-Year Network Development Plan (TYNDP) are the improvement in supply quality, an increase in grid capacity and creation of the solid foundations for sustainable growth in the next decade. The long term goal of the Croatian Distribution System Operator as projected in the TYNDP, is to create a distribution network with only one medium voltage network level of 20 kV and one direct transformation of 110/20 kV. The authors pointed out that the implementation of the TYNDP is necessary to preserve the safety and reliability of the energy supply, which requires investments for the renewal of the grid infrastructure.
