“…The idea of a micro grid has gained popularity recently as a method of incorporating scattered energy sources into conventional power networks [1]. Modern converter architecture known as the modular multilevel converter (MMC) was created in 2003 [2] and is becoming more and more common in high and medium voltage grid applications including HVDC, FACTS, and micro grid.…”

This study examines the performance of a modular multi level converter with a half bridge sub-module (HBSM)-based seven level distribution static synchronous compensator (MMC-DSTATCOM) in low voltage micro grids under unbalanced and flawed system conditions. For MMC- DSTATCOM, the phase angle control algorithm served as the outside control and the phase shift carrier PWM served as the interior control with capacitor balanced control. The effectiveness of MMC-DSTATCOM is investigated in MATLAB/Simulink for a number of simulations, including reactive power compensation, unbalanced, and defective grid scenarios.

“…In addition, they contain intelligent capabilities such as Decision Support Systems (DSS) that can operate independently or guide the system’s operator [ 11 , 12 , 13 ]. MGs often encounter emergencies related to technical issues or extreme weather conditions [ 14 ]. Therefore, the system’s DSS needs to be able to assess the current situation of the grid and assist the operator in making certain modifications in the MG’s management for emergency circumstances, until it returns to its regular operating condition.…”

The usual operation of a microgrid (MG) may often be challenged by emergencies related to extreme weather conditions and technical issues. As a result, the operator often needs to adapt the MG’s management by either: (i) excluding disconnected components, (ii) switching to islanded mode or (iii) performing a black start, which is required in case of a blackout, followed by either direct reconnection to the main grid or islanded operation. The purpose of this paper is to present an optimal Decision Support System (DSS) that assists the MG’s operator in all the main possible sorts of emergencies, thus providing an inclusive solution. The objective of the optimizer, developed in Pyomo, is to maximize the autonomy of the MG, prioritizing its renewable production. Therefore, the DSS is in line with the purpose of the ongoing energy transition. Furthermore, it is capable of taking into account multiple sorts of Distributed Energy Resources (DER), including Renewable Energy Sources (RES), Battery Energy Storage Systems (BESS)—which can only be charged with renewable energy—and local, fuel-based generators. The proposed DSS is applied in a number of emergencies considering grid-forming and grid-following mode, in order to highlight its effectiveness and is verified with the use of PowerFactory, DIgSILENT.
