Abstract
Renewable energy power plant could be a challenge to power grid reliability due to its intermittency issue. Thus, it is necessary to perform a contingency analysis in monitoring system severity after renewable energy addition. The parameter that is commonly used to examine it are transmission line loading and voltage deviation. In this study, contingency analysis was carried out by removing one transmission line on the Batam network in 2025 by applying three different scenarios after connection of Solar Power Plant (30 MW). Those scenarios are analyzed using the voltage (Plv) and active power (PImw) performance index to find out which line outage has the biggest impact to the system. The top three rankings were then analyzed further to see their effect on the system. After Solar Power Plant connection, the largest Plv value occur in scenario 3 which Sri Bintan - Air Raja line outage has the largest voltage deviation (144.99 kV or 0,96 pu) at the Air Raja substation. The largest PImw value is in scenario 3 during Tj Uban - Tj Kasam line outage with the largest loading occur on Uban - Taluh line (40.257 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup> ). Thus, it can be concluded that the Batam system can still operate normally after the PV system is connected. But, the intermittency of PV system causes changes in Plv and PImw values for each different PV system output power.
