This paper studies the parameter stability region of droop-controlled ac microgrid (MG) with
static ZIP (constant impedance, constant current, and constant power) load and dynamic …

The instability issues of the three-phase grid-tied inverters are major concerns in the
distributed generated systems. However, due to the coupling effects in dq frame, the …

Hybrid AC-DC systems integrate ac bus and various dc buses as well as multiple power
electronic converters, and such systems are consequently vulnerable to instability issues. In …

The dc distribution power system (DPS) has witnessed rapid development in recent years,
and it is gradually characterized by multiple voltage levels, multiple dc buses, and multiple …

In this study, stability evaluation is performed through structural analysis based on digital
dental implant design variables. The design variables include the implant length and …

Improving the design of primary and secondary level controllers of microgrids is of critical
importance to microgrid deployment. Controller design and tuning rely heavily upon …

The paper deals with the modeling of an island grid for the purpose of simulation. Since the
behavior of the system is affected by phenomena taking influence in different time-scales, a …

The AC/DC hybrid microgrid, which takes into account the access requirements of AC and
DC sources and loads, optimizes the structure of traditional distribution networks. The …

In recent years, the transient stability problems encountered by power grids have
increasingly attracted interest due to the connection of renewable energy resources. One of …

This paper presents a reduced order model of a microgrid system for a university community
in Nigeria. The designed microgrid system is simulated in MATLAB/Simulink environment to …
