A new method for the stability assessment of inverter-based microgrids is presented in this paper. Directly determining boundaries by searching multidimensional space inverters’ droop gains a computationally prohibitive task. Instead, we build certified region utilizing generalized Laplacian matrix eigenvalues, which are measure proximity to boundary. We establish an upper threshold eigenvalues...

the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

As a cutting-edge technology, microgrids feature intelligent EMSs and sophisticated control, which will dramatically change our energy infrastructure. The modern microgrids are a relatively recent development with high potential to bring distributed generation, DES devices, controllable loads, communication infrastructure, and many new technologies into the mainstream. As a more controllable an...

The idea of a microgrid is created by utilizing more diverse ac or dc distributed generation (DG) sources along with an energy storage system (ESS) and loads. The most efficient and reliable selection of ac and dc microgrids is a hybrid ac/dc microgrid. The hybrid microgrid largely overcomes the shortcomings of standalone ac or dc microgrids. A bidirectional interlinking converter (BIC) is util...

Recently, the concept of microgrids has emerged in world due to integration distributed energy resources (DERs) at distribution end. The design a reliable protection strategy is one top-most challenges associated with microgrids. This because transition between grid-tied and autonomous modes operation. paper presents state-of-the-art microgrid scheme based on Kalman filter (KF). proposed uses o...

Load sharing among distributed generation systems (DGS) is one of the most important topics in wireless-enabled smart microgrids, where a set of power inverters at different geographical locations work coordinately and collaboratively through wireless networks to meet the load requirement. Parallel power inverters operated in distributed generation systems rely on the underlying wireless commun...
