The ever-increasing scale of system interconnection and diverse dynamic time constants of power equipment pose challenges to power system transient simulation algorithms. In this paper, an adaptive numerical integration method for DAE systems based on matrix exponential operator is presented. Krylov subspace technique is utilized to effectively reduce the problem dimension. A novel step adaption scheme...
The dynamics of micro-grid is of great complexity due to the diversity of DG and the highly nonlinearity within the system itself. Transient simulation tool plays a significant role to obtain a full and detailed response under various operation conditions. However, the simulation capability and speed are limited with the increasing size of the system. This paper presents a parallel algorithm for micro-grid...
