Control Method for Energy Trading in Smart-grid

摘要

The present invention relates to a method for controlling distributed power transactions in a distribution network around a power grid with surplus power and, more specifically, to a method where a control system of each power grid measures and calculates consumption power, generation power, and energy storage device storage capacities in each power grid in real time to transmit the consumption power, the generation power, and the energy storage device storage capacities to other power grids in a smart grid distribution network including two or more power grids divided by including one or more distributed power sources and one or more energy storage devices, and aggregates real-time situations received from other power grids and a real-time situation of the power grid to which the control system belongs to supply surplus power to the distribution network or receive power from the distribution network to store power in an energy storage device of the control system. A second power grid having a storable space, namely storable power in an energy storage device is found by a power grid having generation power larger than the sum of consumption power and storable power, namely a first power grid having surplus power, and then the surplus power is supplied and stored in real time via the distribution network.
