Abstract：The load characteristic of pulsed power load (PPL), which is common in the power electronics dominated power system, demonstrates the feature of impact, periodicity and continuity. The working pattern of PPL brings the great challenges to the operation of isolated microgrid, and for this reason, this paper presents the study of a typical PPL, named modern electronic radar, by analyzing the working mode and basic structure. Then, a novel equivalent topology of PPL, which consists of an uncontrollable three-phase rectifier, a Buck circuit and a DC switching load, has been proposed, and the corresponding power-flow calculation model of PPL has been also established. The case-study results demonstrate that, on one hand, comparing with the conventional equivalent topology, which adopted the silicon controlled rectifier to represent the ac-dc energy exchanger, the novel equivalent topology of PPL could improve the accuracy of the equivalent simulation for PPL; on the other hand, the power-flow calculation model of PPL mentioned above is adopted in the power-flow analysis, and the corresponding power flow and node P-U curve is consistent with the theoretical expectations, thus the feasibility of the power-flow model for PPL is verified.
