This technology relates to a charging and discharging scheduling device and method for energy storage devices. It minimizes operating costs and enables stable and planned power grid operation by establishing a charging and discharging scheduling plan in consideration of load pattern data and the internal chemical characteristics of the energy storage device.
Energy storage devices are secondary batteries that can be charged and discharged multiple times, but because their lifespan is limited, efficient charging and discharging scheduling according to the usage environment and purpose is required. It is necessary. However, in terms of the operating cost of supplying power in connection with the power grid, there is a limitation in not considering the internal chemical characteristics of the energy storage device, and the cost-effective management of the energy storage device is not implemented, which can lead to problems that bring a burden of charges to consumers.
This technology considers changes in electricity rates over time, load pattern data, and the internal chemical characteristics of the energy storage device under the condition that the output drawn from the power grid does not exceed the range, and performs charging and discharging scheduling that enables the minimum operating cost. By making it possible to establish a plan, not only can power be supplied cost-effectively in the demand power market, but it can also improve the stability and reliability of the entire power grid by appropriately limiting the amount of power drawn from the power grid and used.
This technology was developed through the support of the National Research Foundation of Korea's research project on ESS operation cost minimization algorithm and hardware-linked charging and discharging test bed construction.
