The basic features of the electrical power grid which is a hierarchical, centrally-controlled structure that assumes that power is generated solely from large central facilities. It also assumes the power is abundant, and the power generation disruption  is a relatively benign issue. Reliability is attained through redundancies and highly controllable generation that reacts to problems such as demand fluctuations and outages, rather than anticipating and avoiding them. Recent developments in Microgrids have upended these assumptions.. Demand has risen sharply and become more variable in recent decades adding significant stress to the grid. Alternative renewable energy sources, including wind and solar, are being integrated into the power grid but their distributed and intermittent nature make them difficult to control. With the existing grid control mechanisms and the ongoing developments, the probability of the existing power grid to survive failures or attacks degrades significantly, emphasizing the need for new tools for power grid analysis.
