Droop control and some improved droop control methods are adopted to control microgrid inverters not only in island mode, but also in grid-connected mode. This paper presents a state space model of three phase paralleled inverters in grid-connected microgrid based on droop control to facilitate the control design and stability analysis. This model is established in rotation framework based on modern...
In a motor control, a voltage saturation is a serious problem as a motor speed increases. To solve the problem, various field weakening methods were studied for a long time. The field weakening methods with PI current controllers are normally used, however the voltage angle control without PI current controllers is receiving attention because of its simple implementation. In this work, the field weakening...
The conventional mathematic model of PV (Photovoltaic) cells contains logarithmic terms, which is not conducive to derivation calculation in small-signal modeling. The parameters of PV system are coupling due to its double-loop control method, and it's hard to precisely choose controller parameters. To solve these two problems above, this paper is based on PV system connected to an infinite power...
