Managing risk in energy storage. Narrative: Since energy storage problems are typically solved in the presence of highly stochastic prices (prices from the grid can jump by factors of 10 to 100, far greater than stock price variations). This paper explores the use of conditional value at risk in the operation of an energy storage problem.
