In a liberalized electricity market, it is not surprising that different customers need different power quality levels with different price. So how to achieve the synthetic grading evaluation of power quality becomes a concerned problem. In this paper, the idea of classified evaluation of power quality is emphasized, and the major differences between the continuous and event-based power quality problems...
The bi-directional DC/DC converter with high power rate plays a key role in power storage system, while it converts DC voltage or DC current for the power storage battery, and then come to the need of DC voltage/current in applications. It illustrates the design of the system hardware and software realization based on this local controller and the host computer structure in detail, in which the local...
The microgrid is a potential solution for future distributed generation systems. It aggregates many distributed energy resources (DERs) and loads together as an autonomous entity. As the penetration of DERs is increasing and their characteristics are very distinct, the control of DERs in microgrid is still a complex task. In this paper, a multi-agent system (MAS) approach, as a branch of distributed...
Available transfer capability (ATC) is defined as a measure of the system's capability for transfers of power for further commercial activity, over and above already committed uses. In practical power markets, ATC can provide important information for transmission customers, system operators and power marketers. The assessment of ATC should be carried out to assure the secure, economic, stable and...
