Optimization strategy of fully controlled device excitation hydropower system based on DLMP

With the grid-connected operation of a large number of hydropower units, how to better absorb hydropower resources has become an important factor restricting the development of hydropower. Therefore, this paper constructs a coupling model of DC transmission model and DLMP model of hydropower system. The aim is to make better use of new energy resources while improving the power index of the power system and ensuring the stable operation of the power system. At the same time, the excitation system based on the full control device is adopted, so that the excitation system can not only provide t he excitation current but also provide the reactive power to the power system. Finally, the simulation results show that the model can improve the power index and improve the consumption capacity of new energy.
