Renewable electricity trading through SLAs
2018
Energy Informatics
Preserved Fulltext
However, if not traded the electricity might need to be curtailed, foregoing potential benefits for both supply and demand sides. ...
We propose to adopt service level agreements (SLAs) that comprise quantity, reliability, and price, for electricity trading in settings where supply depends on volatile power sources. ...

To solve this issue we investigate on the use of forward contracts, i.e., service level agreements priced to reflect the expectation of future supply and demand curves. ...
However, the strictly competitive mechanism can result in service interruption in presence of competing demand. ...
This work differentiates from previous studies, by addressing the stringent requirements and high volatility in power supply and demand typical of microgrids. ...
