Problems solved by technology

Thus, the energy storage system performs repeated operations in order to maintain the desired control value, and due to the repeated operations, there is a limitation that it cannot operate efficiently
In addition, since the energy storage system fails to adopt a margin of error according to the adjustment rules of the electricity market, there is a limitation that battery control operations are repeated unnecessarily

Abstract

The invention provides an energy storage system. The energy storage system including a battery includes a battery management system that monitors a battery state of the battery and controls charging operation and discharging operation of the battery; and a power conditioning system that determines a desired control value of the battery and obtains a power market that includes the energy storage system. Relevant power market adjustment rule information, calculate the dead zone value of the expected control value based on the acquired power market adjustment rule information, and control the battery based on the calculated dead zone value of the expected control value and the monitored battery state The charging operation and discharging operation of the battery management system are controlled.

Description

technical field [0001] The present disclosure relates to an energy system. Background technique [0002] The energy system is a system that stores generated power in various related systems including power stations, substations, and transmission lines and then selectively and efficiently uses the stored power as needed to improve energy efficiency. [0003] When the electrical loads with significant changes due to time zones and seasons are balanced to enhance the total load factor, the energy storage system can reduce the cost of electricity, save the investment cost and operation cost required to increase the power facilities, so it can reduce electricity bills and save energy. [0004] Such energy storage systems are being installed in power generation stations, transmission and distribution stations, and residences in the electrical system, and perform functions such as frequency adjustment, generator output stabilization using new renewable energy, peak shaving, load b...
