“…The VPP can function as a dispatchable unit in power system operations and as a tradeable unit in energy markets [12]. While some concepts on dynamic [13,14], hierarchical [15], holonic [16], and self-organizing [17,18] VPPs have been presented in the literature, VPPs in the field still are typically static systems with a fixed pool of assets [19]. This fixed pool is fully aggregated and marketed for a single purpose at a time, with the result that the flexibility potential of the assets cannot be fully exploited.…”

The future power system will be characterized by many small decentralized power plants—so-called distributed energy resources (DERs). The integration of these DERs is vital from an economic and grid operation point of view. One approach to this is the aggregation of such DERs. The formation of coalitions as an aggregation method has already been examined in the literature and applied in virtual power plants, active distribution networks, and microgrids. The spread of DERs also increases the need for flexibility and dynamics in the power grid. One approach to address this can be overlapping coalitions. Therefore, in this paper, we first performed an analysis of related work and, in this context, found no work on overlapping coalitions for energy use cases in the literature. We then described a method for dynamic coalition formation, called dynamic coalition in electricity markets (DYCE), and analyzed how DYCE would need to be extended to include overlapping coalition formation. The extension includes the phases of product portfolio optimization and the actual coalition formation. Our analysis of DYCE shows that the methods used for the optimization of the DYCE sub-tasks are not suitable for overlapping coalitions and would have to be replaced by other methods in order to be able to form overlapping coalitions.

“…3) The development of power systems combining the expansion of the scale of the grid and the decentralization of power sources has become an urgent issue. 4) In next-generation power systems, multiple AC and DC networks should be interconnected at all grid voltage classes, from grid backbones to distribution systems. 5,6) Such networks should include DC systems connected with regional power systems to expand the scale of power systems, 7,8) DC transmission systems for offshore wind power generation, 7) asynchronous semiconductor circuit breakers for regional microgrids, 7) and high-efficiency inverters with short-time overloads and large capacity, high speed, and virtual synchronous generation functions to cope with short-period fluctuations.…”

Power electronics utilizing SiC power devices will become key components in next-generation power systems based on renewable energy, which are becoming an urgent issue worldwide. In this study, the on-characteristics and switching characteristics of 13 kV SiC-double-implanted metal-oxide-semiconductor field-effect transistors (DMOSFETs) and their body diodes were measured. In particular, the carrier lifetime, which has a significant effect on electrical characteristics, was estimated from the dynamic characteristics of the body diodes. The short carrier lifetime resulted in a large on-state voltage and a small reverse recovery loss of the body diode. Moreover, a conceptual design of a modular multilevel converter-based high-voltage, large-capacity, and self-excited AC/DC converter with 13 kV SiC-DMOSFETs was conducted, and its characteristics were investigated. When the 13 kV SiC-DMOSFETs were applied, the ratio of the total device loss to the electricity power of the converter was 1.10%, which is a significant reduction of 50% compared with 2.17% when 6.5 kV Si-insulated gate bipolar transistors were used.
