  • Power and Energy Laboratory
  • The Power & Energy Laboratory (PEL) at Korea University is an internationally recognized research facility specializing in electric power systems engineering. PEL is a member of APSRC, a MOCIE Research Center, and NPTC, a KOSEF Engineering Research Center. The electricity infrastructure is one of the greatest engineering marvels of the 20th century. However, to meet the rising electric power demand of the 21st century, significant improvements in electric systems are necessary. The laboratory focuses on finding reliable ways to make a large electric power infrastructure more secure and efficient. At one level, the goal for PEL is to have a better understanding of modern power systems with renewable and decentralized energy resources, HVDC systems, and hybrid energy services. On another level, it is to promote an innovative development that integrates knowledge from fundamental study of electrical engineering, computer engineering, and modern information technologies to electric power systems.
