Against the background of liberalization of energy markets, increasing fuel costs and decentralized power generation by renewable energy sources, nowadays running an electrical power grid in an efficient way is becoming more and more important. The problem of determining an optimal operation state and an optimal power grid extension is known as ‘Optimal Power Flow’ (OPF). Mathematically speaking, OPF is a non-linear and non-convex optimization problem in up to millions of variables. Due to its high complexity, power system operators still have to use simplified physical models for describing electrical grids. The project ‘Optimal Economic Power Flow’ aims at developing new numerical approaches to handle the high problem size arising from an accurate alternating current (AC) physical model.
Optimal Economic Power Flow is 2-year research project funded by German Research Foundation (DFG).
