[Abstract]:With the rapid development of national economy, the power system of our country is also developing very rapidly. The power market has gradually implemented and formed the basic situation of "separation of power plants and networks, bidding to surf the Internet", and the strategy of interconnection of large power grids has also been gradually launched. Therefore, it is of great significance to study the coordinated operation between the unit and the power grid, that is, the coordinated operation of the power network, for the security and stability of the whole power system. In this paper, the modeling of power system and power grid system of thermal power plant is studied, and a joint simulation platform of power plant and network is established, and the joint operation system of power plant and network is simulated and analyzed by using the simulation platform. The specific work of this paper is as follows: 1. The mathematical analysis of the main components of the power system of thermal power plant is carried out, and their mathematical models are derived. based on the simulation engine SimuEngine of the power system of thermal power plant, the simulation modules of each part of the power system of thermal power plant are built, and the simulation model of power system of thermal power plant is established. two銆，
