VaR

Review of Financial Economics, 2002
AbstractSince “Value at Risk” (VaR) received its first wide introduction in the July 1993 Group of Thirty report, the number of users of—and uses for—VaR have increased dramatically. However, VaR itself has been evolving. In this article, we will first review some of the important refinements in VaR that have appeared—improved speed of computation ...

Robust Volt/VAr Control With Photovoltaics

IEEE Transactions on Power Systems, 2019
The new IEEE 1547-2018 standard includes dynamic Volt/VAr control for photovoltaic (PV) smart inverters. While recent research has addressed the problem of optimal inverter dispatch, the interaction between inverters and the classical Volt/VAr control ...

VaR

The Journal of Portfolio Management, 2003
When considering how much leverage to use with a real estate portfolio, a good risk measure is needed to evaluate the risk-reward trade-off. The Sharpe ratio, which is not very sensitive to changes in leverage, masks the very different risk/return combinations created by various levels of debt. The authors argue that Value at Risk (VaR) is a far better
