smart power distribution system and a method to progressively dispatch the power is described. The method steps are all automatic and self-adaptive. The method can be executed in an unattended manner to automatically correlate real time data vs. historical data, planning data vs. operation data. Based on a long cycle periodical variation and short-term random variations in load, and taking into account the temporary load power supply and maintenance needs, a multi-stage progressive multiple time scales optimal dispatching method is developed, including the distributed power, micro-grids, energy storage devices, electric vehicles charge-discharge facility and other elements of the Intelligent power distribution systems, to achieve coordinated operation of the network, power, load resources to ensure a continuous safe and reliable smart power distribution system operated at high quality and efficiency.

Progressive optimization dispatching method of smart distribution system

The invention provides a global optimization and dispatching method based on time scales. The method uses a target value system and a dispatch model. The global optimization and dispatching method takes input from the results from a variety of subtopics. The methods provide adjustment and optimization in accordance with the time scales that are given in the sub goal of each sub topic: long-term, mid-long-term, short-term, ultra short term and real time optimization. Smart distribution grid can improve operational efficiency, integrated application of new elements in the distribution network of distribution energy network, micro grid, energy storage device and non-linear loads. This invention is fully adapted to the smart grid trends, with a good prospective.
