Embodiment 1
[0060] figure 1 It is a schematic diagram of network source co-simulation and its multi-level dispatching closed-loop control system. like figure 1 As shown, the network source co-simulation and its multi-level dispatching closed-loop control system provided by the present invention include: a power supply side simulation subsystem, a power grid side simulation subsystem, a protocol conversion module and a dispatching subsystem. Among them, the simulation subsystem on the power supply side is connected to the simulation subsystem on the grid side, the simulation subsystem on the grid side is connected to the protocol conversion module, and the protocol conversion module is connected to the dispatching subsystem.
[0061] The power side simulation subsystem is used to simulate the working status of each thermal power unit, pumped storage hydropower unit and wind farm, generate basic simulation data and send it to the grid side simulation subsystem; it is also used to receive c...
Embodiment 2
[0109] Taking Mengxi Power Grid as an example, the present invention is further described. After the equivalent value, there are 31 525KV nodes, 63 230KV nodes (including 7 wind farm access points) and 47 generators in the western Mengxi power grid. figure 2 It is a flow chart of the grid-source co-simulation and its multi-level dispatching closed-loop control system construction method based on the western Mengxi power grid. The specific steps are as follows:
[0110] Step 1: Build detailed simulation modules of 1000MW, 600MW, and 300MW thermal power units on the power plant simulation system (STAR-90 graphical simulation support system), and the three thermal power units are respectively based on EQG085, Mengdaihai G1, and Mengda Flag G5 as a prototype. Among them, EQG085 is the equivalent machine of the external network, and the data of a 1000MW unit of Guangdong Chaozhou Power Plant is selected. The simulation objects of the detailed simulation models of the three ther...
