This study introduces a simulation method for DC distribution system based on the average-value model (AVM), which replaces the switch to improve simulation efficiency, and constructs the corresponding system in PLECS software. The research shows that simulation based on AVM can effectively reflect the system's characteristics, improve simulation speed, and provide important reference for the stable operation of the system.
Transient simulations with of DC distribution system based on switch model (SM) are computationally expensive because of a large number of switching events in power electronics converters. As an alternative, average-value model (AVM) replaces the switch with controlled source, which can effectively improve the simulation efficiency. This paper takes a typical double-ended DC distribution system as an example and introduces the key equipment selected in the system. Then AVMs of corresponding equipment are given. The DC distribution system based on AVM and SM is built respectively in the PLECS software. The simulation result shows that simulation based on AVM can effectively reflect the steady-state and dynamic characteristics of the system and greatly improve the simulation speed, which can provide an effective and fast reference for the stable operation of DC distribution system in different working modes.
