摘要：

The DC microgrid loads that are power electronics-based often behave as constant power loads (CPLs). DC grid destabilization could occur during load power changes or bus voltage transients because of the negative impedance behavior of these CPLs. When integrating an energy storage, the newly suggested T-type modular dc circuit breaker (T-breaker) can realize current limiting and breaking, and grid transient compensation capabilities as an all-in-one device. Similar to voltage and current compensation devices in ac systems, the ride-through of dc grid transients can be accomplished utilizing the T-breaker's shunt (current) and series (voltage) compensation capabilities. Realizing shunt compensation of the T-breaker using the smart resistor (SR) control is the focus in this work. The article discusses system modeling, small signal stability, large signal stability, simulation, and also shows experimental validations.
