Advanced Power Transmission Technologies Course

Course Description

The world's electric power supply systems are interconnected across regional, inter-regional, and international connections. The purpose of this complex integration is to lower operating costs while enhancing the reliability and security of supply.

Today, the Electrical Supply Industry is undergoing a major transformation. Rising economic pressures, evolving consumer demands, and the increasing adoption of renewable energy sources are creating new challenges. The industry must now deliver higher quality and secure supply while meeting environmental standards such as those emphasized at the Kyoto Summit, all within a decentralized global electricity market.

Power Electronics Control of Deregulated Power Systems will play a vital role in this future. Managing the integration of new-generation power electronic systems worldwide will significantly impact all sectors, including:

• Power Generation
• Transmission
• Distribution
• Utilization
• Equipment Manufacturing
