V&R Energy Systems Research Inc. offers the Physical and Operational Margins (POM) Suite, a comprehensive AC analysis application for analyzing power system behavior. It is fast, flexible and powerful, solving a 45000-bus case in under 0.3 seconds. It allows for high order (N-2 and above) automatic AC contingency analysis.
It also features a quick prediction of cascading outages and addresses FERC’s conditional firm requirements (Order 890). The program automatically determines mitigation measures to alleviate post-contingency violations, and identifies causes of voltage stability violations and alleviates these violations by optimizing reactive sources in the system. It offers fast fault screening for three-phase and unbalanced faults
