1. A system of providing a control service for a TVWS-based hybrid energy storage apparatus in which DC power generated based on solar power is charged into a hybrid solar energy storage device including a plurality of supercapacitors, batteries, supercapacitor modules and battery modules, and the power is supplied to a plurality of loads using the charged power, the system comprising:
a data collection unit configured to collect storage voltage data of the respective supercapacitors, batteries, supercapacitor modules, and battery modules in the hybrid energy storage apparatus and power consumption data of each load;
a central control unit configured to transmit the data collected by the data collection unit through a TVWS channel;
a TVWS gateway connected to the hybrid energy storage apparatus through the TVWS channel to receive the data collected by the data collection unit and transmit the data through a wireless communication network; and
a control server connected to the TVWS gateway to receive the data, and configured to generate control data for the hybrid energy storage apparatus related to amounts of power charge and discharge of the respective supercapacitors and batteries and power consumption data of each of the loads based on the received data, and provide the data to a manager side device;
wherein the hybrid energy storage apparatus further comprises:
a power supply control unit which has a plurality of connection terminals to which each of the loads is connected, and is configured to supply the power stored in the hybrid energy storage unit to each of the loads connected to the plurality of connection terminals; and
a switching unit including switching elements installed between the plurality of connection terminals and each of the plurality of loads and configured to turn on or off power supply according to control of the central control unit,
the control server further comprises a switching policy determination unit configured to calculate importance of each of the plurality of loads for each time zone based on the received data, generate switching policy information for each time zone based on the calculated importance, and then transmit the information to the hybrid energy storage apparatus through the TVWS gateway,
wherein the central control unit performs control on each switching element of the switching unit based on the switching policy information for each time zone.
