Moving towards self-consumption and self-sufficiency: COVID-19 impact in the city of Terni

This paper presents a statistical analysis on producers' data collected between 2015 and 2020 by the DSO in the city of Terni (Italy). The integration of prosumers with the electrical system is investigated through appropriate indicators, such as self-consumption and self-sufficiency, the case study is placed within the Italian and International scenario and enriched with comments and observations. In particular, effects of Covid-19 pandemic to prosumers' behaviour are reported, highlighting an increasing of self-consumption by domestic prosumers, in line with the European and national policy. © 2021 IEEE

A Distribution Network during the 2020 COVID-19 Pandemic

During an extraordinary event, like the COVID19 pandemic, very rapid changes in consumption profiles and customers behaviors were recorded. This paper investigates the impact of the lockdown on load and production in the distribution system of Terni. From a DSO point of view, no relevant issues were encountered to be faced. The distributed power generation from renewable resources did not affect relevant issues, maintaining the typical annual generation profiles. A domestic consumption increase was replaced by more relevant decrease of industrial processes and commercial activities absorptions. More than 25,000 domestic users increased their consumptions in April 2020 and the overall consumption of domestic customers in March was 1,05 times higher than the 2015 respectively consumption. The power flows at primary substations reveal a relevant electric demand reduction for each point of connection with the high voltage transmission system;especially bar 1 and 2 of the most relevant Terni primary substation, recorded a 15.3% decrease with respect to March 2019, and a 24.25% decrease with respect to April 2019. © 2020 AEIT.
