Electric power system with demand-supply adjustment management
The patent US12040617B2 describes an electric power system designed to manage power adjustment resources that are electrically connectable to a power grid. The system includes a management device that processes two types of request signals: one for demand-and-supply adjustments in the power grid and another specifically for adjusting electric energy from a first power adjustment resource within a predetermined period. The management device generates a power command signal that indicates the required power value for each interval during this period, ensuring that the energy supplied from the grid to a microgrid does not exceed a maximum contract power. This is achieved by considering the power generation and load within the microgrid.
Additionally, the patent outlines various configurations for the power adjustment resources, which may include electric vehicles and power storage devices. The management device can calculate power loads based on the charge and discharge capacities of connected electric vehicles, as well as their travel schedules. The system is designed to facilitate efficient energy distribution among the resources, ensuring that the electric vehicles receive power based on their state of charge or evenly distributed as needed. The claims also highlight the integration of nature-fluctuating power supplies and other facilities within the microgrid, enhancing the overall flexibility and responsiveness of the electric power system to changing demand and supply conditions.
