Study on the transient characteristics of distribution network with diverse distributed generators

Firstly, the characteristics of energy conversion about photovoltaic power, wind power and energy storage system are studied. Secondly, a simulation model with diverse distributed power (DP) is set up based on mathematic models study. This model consist of the most popular variable speed wind turbines technology, besides photovoltaic power and distributed energy storage, which are doubly fed induction generator (DFIG), permanent magnet generator (PMG). Thirdly, aiming at the requirement of ride-through for (DP), the transient characteristics of diverse DP are compared based on simulation and theoretical analysis. Finally, the effect of the interaction among various (DP) on transient characteristics is analyzed. Base on this, this paper focus on analyzing the characteristics of fault current o during the distribution network fault. Moreover, the effect of diverse DP on the transient characteristics of distribution network is discussed in detail.
