Small-signal models are mostly used to model and design inverter-dominated microgrids. Conversely, this article proposes a large-signal for grid-forming inverters connected microgrid based on the active reactive power dynamic equations. In work, it is proposed use nonlinear develop constrained predictive control microgrid. The main features of follows: first, direct voltage (in amplitude freque...

Power networks with multiple microgrids require more flexibility and versatility in their coordination tools and decision-making tools from both technical and economical points of view. In particular, the microgrids involve a high penetration of variable energy resources which motivates the need for new coordination and control approaches. In this paper, some of the literature gaps with respect...

Islanded microgrids have low inertia due to a large penetration of non-inertial inverter based power sources. In such systems, the primary frequency controller (PFC) faces issue higher rate change (RoCoF) and peak deviation in case sudden load or generation loss. The control becomes more challenging as variation different sources is not synchronized. This paper proposes model for dynamics an is...

This paper presents a detailed harmonic analysis in terms of Total Harmonic Distortion (THD) for different power circuit topologies of multi level inverter fed induction motor drives. The most common multilevel inverter topologies are the neutral-point-clamped inverter (NPC), flying capacitor inverter (FC), and cascaded H-bridge inverter (CHB). This work is to analyze the performance of all the...

This paper presents a model for reliability evaluation of Microgrids with Distributed Generation based on renewable energy resources. In this approach, DG participates in the network operation coordination as an active agent and not as a decentralized generation under which the utility has no control. Stochastic models are considered for representing generation availability related to wind ener...

In this paper, a simplified space–vector pulse width modulation technique for multilevel inverters is proposed. This method is based on the simplification of the space–vector diagram of a five level inverter into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Hence, the algorithm of five level space-vector pu...

Microgrids have played an important role in distribution networks during recent years.  DC microgrids are very popular among researchers because of their benefits. Protection is one of the significant challenges in the way of microgrids progress. As a result, in this paper, a fault detection and location scheme for DC microgrids is proposed. Due to advances in Artificial Intelligence (AI) and s...
