1. An energy storage system comprising:
a first fluid container for accommodating a liquid and a gas;
a pump configured to pump the liquid into the first fluid container to compress the gas in the first fluid container;
a hydrogenerator driven by the liquid coming out from the first fluid container to generate electricity; and
an electronic controlling system configured to:
selectively control the pumping of the liquid to compress the gas to a predetermined pressure range when in an energy storage mode;
dynamically adjust the predetermined pressure range based on sensed conditions; and
selectively control a flow rate, a flow volume, or both of the first fluid to generate electricity when in an electricity generating mode by driving a hydrogenerator, so that an energy storage efficiency of the energy storage system is optimized.
 
11. An energy storage system controlling method comprising:
pumping a liquid to compress a gas in a first fluid container to a predetermined pressure range when in an energy storage mode by using an electronic controlling system;
dynamically adjusting the predetermined pressure range with the electronic controlling system based on sensed conditions; and
controlling a flow of a first fluid to generate electricity by driving a hydrogenerator with the liquid when in a electricity generating mode by using the electronic controlling system.
