Trends for intelligent power system technical evolution

This paper presents aspects of the technical evolution in micro-networks efficiency with respect to the power quality and system availability. Different potential approaches for market using are shown. The environmental and economic effects of the micro-networks depends of their implementing phases, like design, commissioning and testing. It can be a lot different than the normal main grid, depending on the type of the distributed energy resource (DER) units, load characteristics, power quality constraints and market participation strategies. Testing the operational tasks of a micro-network is an important issue for the researchers. Possible design, control, testing structures and possible power supply of the consumers studies are a purpose of this paper. A DC micro-network consumers testing study case is presented.
