Wind & Solar power generation

Wind Power Generation is:

Unstable and Unpredictable

Expensive

Very nice but:

”Not In My Backyard”

Statements, beliefs, attitude

Evolution of grid designFrom traditional to future grids

Centralized power generation One-directional power flow Generation follows load Operation based on historical experience Limited grid accessibility for new producers

Integration of wind powerBulk generation at transmission level offshore

Ref: EWEA Offshore Factsheet, 2009

• Bulk generation at transmission (HV) level• Development of larger wind farms• Remote locations• Multiple connection points (Multiterminal DC grid)• Cost effective transmission becomes a challenge
