Why Simulate Power Grid Abnormalities? In testing power supplies or power electronics products, simulating power grid abnormalities is essential because real-world power grids are not ideal—they contain various disturbances and faults. Such simulations are critical to ensure the reliability, safety, and compliance of power electronic equipment, such as inverters, UPS, PV inverters, and EV charging stations.

At present, the imbalance between global energy supply and demand has become increasingly pronounced, while mounting environmental protection pressures have created an urgent need to promote renewable energy generation and to strengthen power management. With the continuous expansion of renewable power generation, its impact on grid architecture, power quality, and operational stability has grown significantly.
