The subject specification comprises a generalized grid security platform (GGSP) that can control power distribution and operations in a power transmission and distribution grid (PTDG) in real or near real time. The GGSP can receive data from one or more data sources, including a PMU(s) or an IED(s), which can obtain power system related data and provide at least a portion of such data to the GGSP at a subsecond rate. The GGSP can correlate data from the data sources based at least in part on a temporal, geographical, or topological axis. The GGSP can analyze the data, including performing predictive analysis, e.g., via simulation, root cause analysis, post mortem analysis, or complex event processing, when desired, to facilitate identifying a current or predicted future state of the PTDG, a cause or source of an abnormal condition, or a remedial action execution plan, new operation or maintenance guidance, etc.
