Studi Keandalan pada Sistem Distribusi Tenaga Listrik Wilayah PT. PLN UP3 Medan Akibat Dampak Pandemi Covid-19

Abstract

The Covid-19 pandemic has affected every aspect of life and changed people's lifestyle. Electrical energy is a very important need to support daily life, especially during a pandemic like today, people are more often at home since the implementation of PSBB, schools are carried out online or online (in the network) and work is done from home (Work From Home) which certainly requires electrical energy. With the increase in the amount of electricity use in the residence area, the provider must also increase the amount of electricity supply and maintain the reliability of the electrical energy supplied. An electric power distribution system is said to be reliable if the disturbances and outages that occur within a certain period of time are below the specified reliability index numbers, namely SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index). During the Covid-19 pandemic, namely 2020 - 2022, the cumulative value of the SAIDI reliability index is 8.127, SAIFI is 8.254, and CAIDI is 1.177. For the SAIDI reliability index value above the SPLN 68-2: 1986 and IEEE std 1366-2003 standard values. The SAIFI reliability index value is below the SPLN 68-2: 1986 standard value and above the IEEE std 1366-2003 standard value, while the CAIDI reliability index value is below the SPLN 68-2: 1986 and IEEE std 1366-2003 standard values. Therefore, the reliability of the distribution system of PT PLN (Persero) UP3 Medan can be categorized as not reliable. For the cumulative economic value in the form of losses due to blackouts during the Covid-19 pandemic period, namely 2020 - 2022, it amounted to Rp. 3,199,655,454.63.
