The droop controllers of inverter-based resources (IBRs) can be adjustable by grid operators to facilitate regulation services. Considering the increasing integration IBRs at power distribution level systems like microgrids, cyber security is becoming a major concern. This paper investigates data-driven destabilizing attack and robust defense strategy based on adversarial deep reinforcement lea...

This paper presents a method for controlling the voltage of inverter-based Microgrids by proposing new scale-free distributed cooperative controller. The main contribution this is that proposed controller where independent any information about communication system and number generators, as such it works with size. Moreover, network modeled general time-varying graph which enhances resilience p...

Currently, inverter-based stand-alone microgrids are gaining interest due to the advantages of obtaining energy from renewable sources. To manage operation, these include storage systems connected in parallel PCC through electronic inverters that controlled as voltage sources order support frequency and at PCC. For purpose ensuring P Q sharing among also synchronization stability microgrid, dro...

This paper describes microgrids in the smart grid architecture, autonomous systems interacting through the Energy Services Interface as defined by the OASIS Energy Interoperation [1] specification. We define for the purposes of system architecture what a microgrid is. The several types of existing microgrids are defined, based on the motivations of those that operate them, the technologies they...

This paper presents an optimal coalition formation mechanism of microgrids in a smart distribution system and analyzes the characteristics from the coalitional game theoretical perspective. Microgrids coalitions can (1) minimize the energy burden and dependency on the utility grid, (2) minimize the overall grid network power loss, and (3) maximize intra-coalition energy transfer. In order to fo...

Microgrids can operate both in grid-connected and islanded modes. It is essential to protect microgrids against all types of faults in both of the operation modes. Conventional overcurrent protection schemes are not adequate for microgrids due to bidirectional flow of fault current and limited flow of fault current through semiconductor devices. In addition, the setting values of all the concer...

Several control schemes specifically designed to operate inverter-based industrial microgrids during voltage sags have been recently proposed. This paper first classifies these control schemes in three categories and then performs a comparative analysis of them. Representative control schemes of each category are selected, described and used to identify the main features and performance of the ...

Grid-forming inverter-based autonomous microgrids present new operational challenges as the stabilizing rotational inertia of synchronous machines is absent. The design efficient control policies for grid-forming inverters is, however, a nontrivial problem where multiple performance objectives need to be satisfied, including voltage/frequency regulation, current limiting capabilities, and activ...
