Abstract
The invention is a smart grid integrated electric power control system based on ESS distributed control, in which the households on a smart grid are grouped into plurality of local ESS areas and the electric power supplied to the households in the local ESS area is controlled distributedly by a local ESS device and the electric power supplied between the local ESS is controlled by a central ESS device integratedly.
Claims7
A smart grid integrated electric power control system based on ESS distributed control in which the households on a smart grid (SG) are grouped into a plurality of local ESS areas (Ea to Ed), and the electric power supplied to the households in the local ESS area is controlled distributedly as well as integratedly, wherein the electric power control system includes local ESS device (200) placed on each local ESS area and connected to its households and the local ESS devices (200) of the other local ESS areas through multi-connecting network R capable of communicating data and supply electric power, and having a new renewable energy generator (250) and a battery (260) and distributedly controlling to supply electric power produced in that new renewable generator (250) to the households in that local ESS area and store the surplus electric power in that battery (260);
- and a central ESS device (100) connected to each local ESS area through the multi-connecting network (R) and monitoring the state of electric power demand and supply of the local ESS areas and integratedly controlling to supply the electric power from a surplus local ESS area in which the amount of electric power production or storage is higher than the predetermined values to a deficit local ESS area in which the amount of the electric power production or storage is lower than the predetermined values.
A smart grid integrated electric energy control system based on ESS distributed control of 1, wherein if the central ESS device (100) is shut down or the connecting network R between the central ESS device (100) and the local ESS devices (200) is disconnected, any local ESS device (200) is given a master function according to a predetermined priority and the other local ESS devices (200) are given slave functions, and the master local ESS device (200) controls the supply of electric power for the other slave local ESS devices (200).
