Electric power exchanges with sensitivity matrices: an experimental analysis

We describe a fast incremental method for power flows computation tailored for electric power markets. Fast in the sense that it, can be used for real time power flows computation, and incremental in the sense that it computes any additional increase/decrease in line congestion caused by a particular (n-lateral) contract. Incremental methods offer a powerful way of dealing with congestion contingency, improve information flows among market entities, and are easy to understand. In this document we provide basic scaling properties for electric power markets using this method, and compare it with methods using (linearized) power flow code.
