“…Still, power electronic interfaces may be used in AC microgrids to achieve a more flexible control of the power flow in between the main grid and the microgrid. One example of the advantages of having more flexible control is found in the microgrid in [34], where a power electronic interface between part of the microgrid and the main grid serves to provide multiple power quality levels within the microgrid area.…”

Aspects of terrestrial microgrids and ship power systems are examined. The work exposes a variety of technical synergies from these two power systems to effectively advance their technologies. Understanding their overlap allows congruent efforts to target both systems; understanding their differences hinders conflict and redundancy in early-stage design. The paper concludes by highlighting how an understanding of both systems can reduce the investment in research resources.

“…A microgrid is a local cluster of sources and sinks that operates semi-autonomously of the grid, being able to island and reconnect as circumstances dictate. Providing appropriate HeQ to match the requirements of end-uses is a central feature of some microgrid concepts, notably the Consortium for Electric Reliability Technology Solutions (CERTS) Microgrid, and the NTT Facilities microgrid being demonstrated in Sendai, Japan [11,12,13,14]. In the case of the CERTS Microgrid, HeQ is provided by segregation of loads on separate circuits.…”

Some of the economics of the dispersed vision are explored. Economic perspectives are presented on both the choice of homogeneous universal power quality upstream in the electricity supply, and also on the extremely heterogeneous requirements of end-use loads. Finally, the potential role of microgrids in delivering heterogeneous power quality is demonstrated by reference to two ongoing microgrid tests in the U.S. and Japan.• Index Terms--cogeneration, dispersed storage and generation, power quality, power system economics

“…It can be more convenient to differentiate the power quality levels for different types of electric consumers. A project in the Consortium for Electric Reliability Technology Solutions (CERTS) [18] and a fouryear project in Sendai, Japan, [19]- [21] have demonstrated the need for multiple-power-quality-level (MPQL) service for future grids. A power quality control center is established to differentiate the power quality level for different areas.…”

, "Tertiary control of voltage unbalance compensation for optimal power quality in islanded microgrids," IEEE Trans. Energy Conv., 2014, IEEE Early access. Abstract-In multi-bus islanded microgrids, the power quality requirements for different areas and buses can be different. This paper proposes a hierarchical control to realize optimal unbalance compensation for satisfying the power quality requirements in different areas. Primary and secondary controllers are applied to realize unbalance compensation for critical bus (CB) and at the same time, to make distributed generators (DGs) equally share the compensation efforts. Tertiary control, which inherently is an optimization method, is implemented to adjust the compensating effort of each DG considering the voltage unbalance limits in local buses and DG terminals. This method realizes multi-power-quality-level control in a multi-bus islanded system by optimally utilizing DGs as distributed compensators and saves the investment for additional compensation equipment. VUFUpper limits of VUF value on LB or DG sides.
