Abstract

This storage battery system is connected to a power grid and operates on the basis of charging / discharging requests from an EMS. The storage battery system is provided with: a storage battery; a BMU that monitors the state of the storage battery by means of a first sensor; a PCS that executes charging of the storage battery and discharging of the storage battery by referring to the output values of the first sensor and a second sensor of the same type; and a control device. The control device is configured in a manner so as to receive the charging / discharging requests and storage battery information supplied from the BMU, and to control the PCS on the basis of the charging / discharging requests and the storage battery information. An abnormality detection unit of the control device acquires the output value of the second sensor from the PCS, and detects a sensor abnormality from the results of comparing the output value of the first sensor and the output value of the second sensor contained in the storage battery information.

Description

technical field [0001] The invention relates to battery systems connected to electrical power systems. Background technique [0002] The power system is constituted by connecting power generation equipment with load equipment through power transmission and distribution equipment. Power systems vary in size, ranging from large-scale systems that connect multiple large-scale power plants to multiple factories, commercial facilities, and residences, to small-scale systems constructed within specific facilities. Regardless of the size of the power system, there is an energy management system (EMS) that manages the power supply and demand of the entire power system. The EMS is used to balance the power supply of the power generation equipment and the power consumption of the load equipment. [0003] The storage battery system is connected to the above-mentioned electric power system, and it is used as a means to balance the supply and demand of electric power. In the past, it w...
