Presentation Title:

NOVEL CAR SOCIETY BASED ON DYNAMIC WIRELESS POWER SUPPLY AND SOME KEY TECHNOLOGIES FOR ITS REALIZATION

Abstract:
'Motor', 'Capacitor' and 'Wireless' will be the keywords for vehicles in the next 100 years, instead of 'Engine', 'Battery' and 'Quick charge'. There are few problems in motor-based propulsion technique, but we still have lots of problems in energy supply. Why are electric vehicles supposed to be charged with 'stopped', in a 'short time', and by ‘big energy’, even though the energy form of electricity is completely different from that of gasoline. Wireless power transfer during parking is ready to be commercialized; however, wireless power transfer during driving requires completely different technologies. It cannot be realized so easily, but there are some hints. In this talk, I will consider several key technologies and make some discussions.

Presentation Title:

NEW RESEARCH CHALLENGES IN INDUSTRIAL AND RESIDENTIAL MICROGRIDS

Abstract:

A microgrid can be defined as a part of the grid with elements like distributed energy sources, power electronics converters, energy storage devices and controllable local loads that can operate autonomously in islanded mode but also interacting with the main power network in a controlled, coordinated way. Following the introduction of distributed control of these elements, cooperative control and hierarchical control schemes for coordination of power electronics converters in order to control the power flow and to enhance the power quality will be elaborated. Different technologies are combined together, such us power converters, control, communications, optimization, and so on. This way, energy can be generated and stored near to the consumption points, improving stability and reducing losses produced by large power lines. In distributed energy systems like microgrids, multi-agent systems technologies will be presented, including distributed control.

Previous experiences in the Danish electrical system like the Cell Controller project used these technologies to balance dispersed energy generation and consumption. The focus of this presentation will be on the analysis, modelling, and control design of power electronics-based microgrids, as well as power electronics control and communications. Further, the interconnection of microgrid clusters will be emphasized as an important step towards utilization of the smart grid concept. Examples of real sites including conventional islanded systems installed in islands and rural remote areas will be shown. Finally, low-voltage distribution systems and DC microgrids for residential applications and homes will be introduced. New worldwide projects to develop technologies for low voltage DC distribution systems will be shown.
