Risk Scenario

In the context of increasing the importance of power safety for national security, the security of power systems within the National Power Grid, must be an objective of major and constant interest for the national transmission and system operator. Evolutions in recent decades have shown the increase in vulnerabilities caused by: failure, destruction and/or disruption of technological infrastructures caused by acts of terrorism, natural disaster, negligence in service, work accidents of technical nature, technical incidents, criminal activities and lack of investment. For the critical analysis of the National Power Grid, 4 (four) possible risk scenarios with effects of instability of the power safety and with major effects on the national security were identified, described and evaluated: Risk Scenario 1 - Technical Incident, Risk Scenario 2 - Damage: Technical Incident Sequence, Risk Scenario 3 - Damage: Natural Disaster, Risk Scenario 4 - Damage: Terrorist Attack. The purpose of the paper is to describe and evaluate the Risc Scenario 1- Technical Incident (which is most prevalent) on the power substations and to prevent potential disturbances in the safety of the power supply to consumer.

The environmental impact of battery electric vehicles (BEVs) largely depends on the environmental profile of the national electric power grid that enables their operation. The purpose of this study is to analyze the environmental performance of BEV usage in Korea considering the changes and trajectory of the national power roadmap. We examined the environmental performance using a weighted environmental index, considering eight impact categories. The results showed that the weighted environmental impact of Korea’s national power grid supply would increase overall by 66% from 2015 to 2029 using the plan laid out by the 7th Power Roadmap, and by only 33% from 2017 to 2031 using the 8th Power Roadmap plan. This change reflects the substantial amount of renewables in the more recent power mix plan. In 2016, BEV usage in Korea resulted in emissions reductions of about 37% compared with diesel passenger vehicles, and 41% compared with gasoline vehicles per kilometer driven (100 g CO2e/km versus 158 g and 170 g CO2e/km, respectively) related to transportation sector. By 2030, BEV usage in Korea is expected to achieve a greater emissions reduction of about 53% compared with diesel vehicles and 56% compared with gasoline vehicles. However, trade-offs are also expected because of increased particulate matter (PM) pollution, which we anticipate to increase by 84% compared with 2016 conditions. Despite these projected increases in PM emissions, increased BEV usage in Korea is expected to result in important global and local benefits through reductions of climate-changing greenhouse gas (GHG) emissions.
