Problems solved by technology

Because the electric meter of the existing grid-connected power storage system cannot provide the objective contribution of the power storage system, such as how much power is charged, how much power is discharged, and how much demand is reduced, and it is impossible to request payment from the user, so the existing structure is not suitable Valuation on lease

Abstract

Provided are a charge and discharge control method and a lease service pricing system for a grid-connected energy storing system. The system comprises a first electric meter and a control device. Thefirst electric meter measures a required electric quantity of an electric load between the grid-connected energy storing system and the electric load. The control device compares the required electricquantity of the electric load and a set range. When the required electric quantity of the electric load is greater than a set range, the grid-connected energy storing system starts to release electric energy, the discharge power is a differential between the required electric quantity and a discharging set value. When the required electric quantity of the electric load is in the set range, the grid-connected energy storing system does not release and store the electric quantity. When the required electric quantity of the electric load is lower than the set range, the grid-connected energy storing system starts to store the electric energy, the charging power is a differential between the discharging set value and the required electric quantity, charging and discharging powers are recorded, related data required by the lease service pricing system for the grid-connected energy storing system is deduced.

Description

technical field [0001] The present invention relates to a charging and discharging control method and a leasing service pricing system, in particular to a charging and discharging control method and a leasing service pricing system of a grid-connected power storage system. Background technique [0002] Battery power storage technology can be divided into independent power storage system and grid-connected power storage system according to the application form. The independent power storage system is separated from the mains power when used, and is applied to independent houses, mobile devices or vehicles. The grid-connected power storage system is combined with the mains power when used. Part of the power source is the mains power and the other part is battery storage. It is usually used in non-mobile facilities, such as homes, shops, offices, factories, etc. [0003] Stand-alone power storage systems are most commonly used in electric vehicles, but battery cost, depreciatio...
