As the electric energy industry is deregulated, the previously regulated and vertically integrated utilities become independent and market driven entities, the functions of the optimization operation tool-Optimal Power Flow(OPF) will be enhanced. This paper analyses the technique and economic merit of OPF at first, and then gives full presentation of recent research achievement for OPF in power market circumstances. The development in several application areas of OPF is especially discussed, such as spot price calculation, ancillary service pricing, congestion management, transmission costing, and available transfer capability determination. Finally, based on some open problems and new conceptions in the power market, the direction of future research for OPF is summarized in the paper. This project is supported by the Key Project of National Natural Science Foundation of China (No.59937150).
