Abstract
- Security metric deployment is of immense importance for power utilities especially in future smart grids, which are being actively pursued in smart cities initiatives around the world. Through these metrics, utilities attain real-time awareness of the grid’s security posture. In this paper, we propose a contingency analysis based security evaluation framework for smart grid systems - CASeS. Based on the power flow equations of the grid, communication network characteristics, and concurrent power contingencies, CASeS leverages Markovian Decison Processes (MDP) to quantify the smart grid security. The security index delivered through CASeS emerges as a novel solution for concurrent power contingency consideration, and allows for the preparation of corrective actions to address the quantified grid criticality level. We evaluate CASeS on the standard IEEE 14-Bus and 39-Bus systems. The collected results demonstrate the usefulness of CASeS in quantifying the security of those systems. [ABSTRACT FROM AUTHOR]
