Grid connection of Renewable Energy
Two main areas to be studied when the proportion of solar and wind increases.
Local issues
Large area issues

Not a new grid but -
an evolution of the grid!
Grid connection of Renewable Energy
Local issues
Capacity
Voltage control and stability, harmonics
Also remember the decrease and variation in short circuit power due to the reduction of “rotation mass”.

2020 Sweden plans for 30 TWh – this corresponds to approx. 11 000 MW installed power.
Imagine a day with decreasing wind, low temperature and high industrial load.
Imagine a weekend in the summer with high wind speed.
Large area issues
Balance of power
Transmission capacity
Grid connection of Renewable Energy
Technologies to solve the issues exists!

Transmission reinforcements, HVDC, FACTS… © ABB Group March 30, 2012 | Slide 10
Grid connection of Renewable Energy
Connecting renewable energy such as wind and solar to the power grid will impose new challenges.
Locally issues such as steep power changes, voltage stability, voltage control, harmonics and capacity are areas that needs to be studied.
Smart Grid technologies will be one solution to handle the balancing issues.
Technology exists today to handle the challenges!
System knowledge is lacking!
Market lacks models to cover the cost for necessary reinforcements! © ABB Group March 30, 2012 | Slide 11
