“…It overcomes the shortages of the conventional power-sharing methods such as droop and VMS etc., by the parallel connection of multiple inverters on a single bus. Also, the scaled-up slack generator can be simply applied to solid-state transformers [27]- [28]. The small current rating of the power electronics switch can be overcome by the parallel-connected multiple solid-state transformers.…”

It is expected that the penetration of renewable-energy-based generators will rapidly increase worldwide. These factors also lead to an increase in the portion of inverters in the power system. This paper proposes a method to scale up the slack generator size based on parallel inverters. All of the multiple parallel inverters except one share the measured power from the slack bus to the grid by a predetermined ratio based on their sizes. A single inverter that does not participate in power sharing is allocated to be in charge of clearing the small power gap caused by the control delay and the measurement error (i.e., the physical slack). As a result, the net size of the scaled-up slack generator is n times greater than that of the physical slack when n non-slack inverters are added to the physical slack inverter. The proposed method is validated based on a real island power system model in Korea using a power system computer-aided design/electromagnetic transient including DC (PSCAD/EMTDC TM ).INDEX TERMS DG acceptability, large IFSA microgrid, load sharing, parallel inverter connection, scaleup of slack generator.

“…For the AC-DC SST, there are mainly two types of solutions. The most popular one is the cascaded topology [2]. Because of the high input voltage and high output current requirement of the electrolyzer system, usually the input series and output parallel (ISOP) structure is used.…”

<p> For electrolyzer applications, traditional solutions using line frequency transformers plus rectifiers are bulky, heavy and have low controllability. The Solid State Transformer (SST) could be a promising solution to solve the mentioned issues. This paper compares the semiconductor ratings and capacitance of five different Modular Multilevel Converter (MMC) based Solid State Transformer (SST) topologies. The results show that the DRU-MMC based topologies have the lowest semiconductor ratings and capacitance. Because of the unidirectional power flow requirement, the source side MMC of Back-to-Back (BtB) MMC based SST could be replaced by DRU, thus the cost is drastically saved. Another interesting finding is that the DRU-MMC energy ripple is much lower than half of the energy ripple in BtB MMC, which is different from HVDC MMC. </p>
