ESS(Energy Storage System) is an energy storage device that stores electrical energy so that it can be used when power is needed. ESS is one of the key elements in implementing next-generation power grids and is a very important industry that is dependent on a power infrastructure that is useful in conjunction with power grids. The power infrastructure industry, including ESS, is the nation's top-tier industry, and values publicity as a key industry. ESS uses lithium-ion batteries and Redox-flow batteries to store electrical energy produced by solar power and wind power, and then supplies charged electrical energy to the power system to stabilize and increase efficiency. By using ESS, it contributes to improving power quality as well as improving stability of the power system and efficient use of power generation power by rapidly charging or discharging stored electric energy when connecting power generation power such as renewable energy to the power system. However, lithium-ion batteries, which are frequently applied to ESS for solar power systems, have high voltage, high energy density, non-memory effects, but overcharging, shock, insufficient protection, and lack of installation conditions, resulting in frequent explosion and fire of lithium-ion batteries. In December 2018, the government launched a "public-private joint fire accident investigation committee" to investigate the cause of ESS fires and announced the results in June 2019 and strengthened ESS installation requirements and protection measures. In this paper, I propose methods to reduce fire generation based on the results of thermal runaway analysis, which is the main factor of fire in lithium-ion batteries, and fire prevention measures study of ESS for solar power linkage. I hope that the solutions proposed in this paper will be realized to protect lives and property and stabilize the solar power generation power system.
