Problems solved by technology

[0011] However, in such prior art, when batteries with different SOC operating ranges are used at the same time, it is necessary to study the processing and rules in accordance with each operating range, so it is difficult to apply to a system requiring many batteries, and there are cases where the efficiency is low.

Abstract

A storage battery control apparatus according to an embodiment is provided with a first reception unit, a second reception unit, a calculation unit, a generation unit, and a transmission unit. The first reception unit receives a charge / discharge command from a power management device. The second reception unit receives a current power storage state from each of a plurality of storage batteries. The calculation unit calculates a control amount indicating the proportion of the operating range of the current power storage state for each of the plurality of storage batteries on the basis of the present power storage state and the operating range of the power storage state. The generation unit generates a charge / discharge output value, which is the charge / discharge output value for each of the plurality of storage batteries, on the basis of the control amount calculated for each of the plurality of storage batteries and the received charge / discharge command. The transmission unit transmits the generated charge / discharge output value to each of the plurality of storage batteries.

Description

technical field [0001] Embodiments of the present invention relate to a battery control device and a battery control method. Background technique [0002] In recent years, the introduction of natural energy such as solar power and wind power has become popular, and the installation of solar panels in the homes of ordinary users is also making full use of these natural energies. Since such a power generation device using natural energy is influenced by weather, weather, etc., the power system may be unstable. [0003] In order to eliminate such instability in the power system, a technique is known in which a storage battery is connected to the power system and output adjustment based on charging or discharging of the storage battery compensates for fluctuations in power generation due to natural energy or the like. As such a technique, for example, load frequency control (LFC: Load Frequency Control) for adjusting output in accordance with electric power demand is known. In...
