Hybrid cascaded-parallel microgrid is becoming a new emerging structure to integrate multiple low-voltage power sources. This paper presents unified distributed control strategy implement sharing in hybrid under both resistive-inductive (RL) and resistive-capacitive (RC) load, where sign function introduced automatically match load characteristic. Active reactive regulators without frequency drop are developed, low bandwidth communication network employed support management improve system...
This paper presents an integrated series-parallel microgrid(MG), where a few distributed generation(DG) units in series type are used to form DG string, then strings supply power the common load parallel type. With this structure, low-voltage devices could be into MG without DC-DC boost converters. It provides more flexible and efficient way higher voltage level MG. But it is difficult find decentralized control method achieve balance for system because of difference between transmission...
The stability problems caused by converter interaction challenge the safe operation of dc power electronic systems (PESs). Online monitoring methods need to be developed urgently prevent instability risk for PESs. existing impedance measurement-based are invasive and widely deployed measurement units, which is difficult realize. In this article, a semisupervised data-driven online framework based on empirical mode decomposition (EMD) semigenerative adversarial network (SGAN) first proposed...
The hybrid series-parallel microgrid (HSPM) is a new type of with wider applicability and higher efficiency. Distributed generations (DGs) are connected in series to form DG string, many strings supply power parallel. However, the conventional droop control not suitable for HSPM due its complex structure. Existing methods rely on central controllers or communication networks, detriment reliability flexibility. In this paper, transmission characteristics analyzed low dependency strategy...
DC-DC converter ICs have been widely used in portable electronic products due to their high efficiency and integration. However, the manufacturing use, it will encounter problems such as voltage instability, poor soldering, component damage, which affect normal operation of entire system. Most existing fault diagnosis methods rely on human experience, dependence labeled data is relatively large, makes production process time-consuming, laborious costly. In order solve these problems, this...
