The embodiment of the invention discloses a micro-grid simulation method and device. The method comprises the steps of comparing a preset first variable with a first thread variable value and comparing a preset second variable with a second thread variable value every a preset system simulation time step length; if the first variable is the same as the first thread variable value, triggering a power electronic simulation device corresponding to the power electronic device to enable; and if the second variable is the same as the second thread variable, triggering a fault protection simulation device corresponding to the fault protection device to enable. According to the micro-grid simulation method and device provided by the embodiment of the invention, the power electronic device and thefault protection device of the micro-grid can be simulated in real time, and the simulation efficiency and the simulation effect can be improved.
Description
technical field [0001] The present invention relates to the technical field of simulation, in particular to a method and device for simulating a microgrid. Background technique [0002] Generally, a microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads and fault protection devices. Such as figure 1 as shown, figure 1 A schematic diagram of the microgrid is shown. in, figure 1 Power electronic devices include: distributed power sources, energy storage devices, and energy conversion devices. The fault protection device can identify whether the microgrid is faulty and realize fault location of the microgrid. [0003] Simulation of microgrid is an important means to improve the security of microgrid. Dynamic physical simulation and real-time digital simulation can directly reflect the performance of the microgrid. It belongs to the online simulation method, which ...
