Problems solved by technology
[0005] (3) Usually, in the power system simulation, only the energy flow, that is, the consumption management of power and load, the safety control of power equipment, and the stability of the power system are considered, but the actual network communication protocol and signal transmission process in the power system are often ignored. simulation;
Taking an ordinary PC as an example, its basic configuration is Inter(R) core(TM) i7-7500U CPU and 8.00GB RAM. The actual time consumed is usually more than twice the simulation time of the model setting, and the offline simulation control algorithm and the controlled object are usually in one model file, which cannot achieve multi-step interactive operation, let alone simulate real network communication conditions

Description
technical field [0001] The invention belongs to the technical field of power system simulation, and relates to a multi-step parallel power real-time simulation system and method. Background technique [0002] In the power system simulation, in order to be closer to the actual system operating environment, and the simulation effect is more authentic and reliable, the following requirements need to be met: [0003] (1) Power system simulation In addition to system-level energy management, power electronics equipment-level simulation is also very important. Power electronics-level modeling can accurately measure and control voltage, current harmonics, and response speeds generated during system operation; [0004] (2) In a real power system, the step size calculated and issued by the controller instruction is not always the same as the operation step size of the controlled equipment; [0005] (3) Usually, in the power system simulation, only the energy flow, that is, the consu...
