Simulation of microturbine generation system performance during grid faults under new grid code requirements

New grid codes requires distributed energy resources to ride through temporary low voltage event and at the same time injecting reactive current into the grid. In microturbine generation system (MTGS) connected to the grid through power electronic converter, during low voltage ride through, its DC-link voltage increases and MTGS converter is overloaded. The paper discussed and highlights the problems and proposed solutions to mitigate these problems. The effectiveness of the solution is demonstrated using digital simulation. Result shows that MTGS is capable of riding through low voltage events while adhere to new grid code requirements without operating beyond its electrical components permissible limit.
