This article proposes a power sharing control method based on the linear quadratic regulator with optimal reference tracking (LQR-ORT) for three-phase inverter-based generators using inductor-capacitor-inductor (LCL) filters islanded mode. Compared to single-input single-output (SISO)-based controllers, LQR-ORT controller increases robustness margins and reduces value of error inputs during tra...

This paper presents a control method for the Doubly-fed Induction Generator connected to a dc link through a diode bridge on the stator. In this system, the rotor is fed, at the slip frequency, by a PWM electronic converter and the stator is directly connected to the dc link using a simple diode bridge. The cost of power electronics is reduced in this system when compared with the classic DFIG ...

This paper studies a secondary voltage control framework of the microgrids based on the consensus for a communication network of multiagent. The proposed control is designed by the communication network with one-way links. The communication network is modeled by a directed graph. At this time, the concept of sampling is considered as the communication constraint among each distributed generator...

Networked Microgrids (NMGs) offer a new, more resilient alternative to traditional individual Microgrids (MGs). Even though networking existing microgrids presents clear advantages, the scalable and resilient communication and control infrastructure necessary for supporting this innovation does not yet exist. This paper addresses this challenge by developing a Software-Defined Networking (SDN) ...

Rapid growth in the utilization of inverter-interfaced distributed energy resources (IIDERs) microgrids has brought new challenges network protection area. Microgrid specifically becomes a concern during operation islanded mode. There is considerable reduction fault current levels this mode compared to when microgrid connected grid, which makes conventional algorithms operate with significant d...

This paper presents formulation and analysis of a distributed consensus-based controller for power electronics based microgrids (MG) with grid forming (GFM) feeding (GFD) inverters. The control is supported by measurements from high reporting rate meters that improve the dynamics consensus enables participation buses no dispatchable units. study performed on developed cyber-physical (CP) model ...

The main purpose of developing microgrids (MGs) is to facilitate the integration renewable energy sources (RESs) into power grid. RESs are normally connected grid via electronic inverters. As various types increasingly being electrical grid, systems near future will have more inverter-based generators (IBGs) instead synchronous machines. Since IBGs significant differences in their characteristi...

Protecting inverter-interfaced microgrids is challenging as conventional time-overcurrent protection becomes unusable due to the lack of fault current. There a great need for novel protective relaying methods that enable application coordination on microgrids, thereby allowing with larger areas and numbers loads while not compromising reliable power delivery. Tools modeling analyzing such under...
