Assessment of Renewable Acceptance by Electric Network Development Exploiting Operation Islands

Abstract

The framework of energy transition poses significant challenges in subtransmission network development, where the increased renewable energy generation is collected, in order to efficiently convey power production, avoiding limitations in a range of operating conditions. In this paper, a method to evaluate possible margins for further renewable penetration due to electric network development is assessed, by means of scenario evaluation for the concretisation of renewable initiatives, combined producibility analysis, and load flow studies, accounting for operation islands in subtransmission network organisation, carried out in N and N-1 conditions. The method is applied to a provisional model of the southern part of the Italian power system.

Power-Flow studies on the Future Electricity Grid of Sicily: Analysis of 2030 Scenario Cases

“…Italy's geographical location and conducive climate conditions make it well-suited for solar and wind energy generation. The country, however, extends more in the North-South direction, making the availability of renewable energy greatly different between northern and southern areas: as a result, there is a larger number of installations in the South of the country and the two major islands, Sicily, and Sardinia [3]. Given its strategic location, Sicily is the object of a broad attention from all actors in the power system, which makes it the perfect candidate as an Energy Hub for the Mediterranean Area [4].…”
