Economic Modeling of Nuclear Hybrid Energy Systems

SPEAKER: DR. CRISTIAN RABITI DATE/TIME: MON, 04/02/2018 – 4:00PM TO 5:00PM LOCATION: 3105 ETCHEVERRY HALL Spring 2018 Colloquium Series Abstract: The increase penetration of variable renewable electricity suppliers in the grid is leading to an increase volatility of the electric net demand (electricity demand minus variable renewable supply). The additional volatility increases the cost of covering net demand…
