ELECTRICITY CUSTOMERS HYBRID ENERGY STORAGE SYSTEM AND OPERATION METHOD THEREOF

摘要

A hybrid energy storage system for electricity consumers and an operation method thereof are disclosed. The hybrid energy storage system according to the present invention includes: a short-period storage system which supplies short-term electricity within four hours, stores electricity energy, and reduces peak loads of electricity consumers; a long-period storage system which continuously stores midnight surplus electricity for at least seven hours and discharges the electricity into the electricity consumers during peak hours; an electricity meter which measures electricity which the electricity consumers used during the set period; and an energy management device which monitors operating conditions of the electricity consumers based on the electricity measured by the electricity meter and controls the short-period storage system and long-term storage system so as to manage driving by the electricity consumers.
