In this paper, the risk of damages to humans and properties due to fire explosions in gasoline storage tanks is identified, and the effects of radiant heat on adjacent tanks are evaluated to present the necessary area to secure safety. A simulation was conducted to evaluate the effect of radiant heat (Maximum emission) on adjacent tanks in an oil storage tank fire due to environmental conditions (Wind speed and temperature) in the Northern Gyeonggi Province. The result indicated that the radiant heat released in the fire of an oil storage tank was increased by approximately 1.9 times by the maximum wind speed and the difference occurred in the range of 700~800 kW by the maximum temperature. If a storage tank fire occurs, securing approximately 34.4 m of holding area is necessary. In the future, evaluating the radiant heat emitted by the fire of gasoline storage tanks will be required by applying various environmental conditions, and through this, research on specific and quantitative holding area is required.

The rising share of renewable energy in the energy mix brings with it new challenges such as power curtailment and lack of reliable large-scale energy grid. The forecasting of wind power generation for provision of flexibility, defined as the ability to absorb and manage fluctuations in the demand and supply by storing energy at times of surplus and releasing it when needed, is important. In this study, short-term forecasting models of wind power generation were developed using the conventional time-series method and hybrid models using support vector regression (SVR) based on rolling origin recalibration. For the application of the methodology, the meteorological database from Korea Meteorological Administration and actual operating data of a wind power turbine (2.3 MW) from 1 January to 31 December 2015 were used. The results showed that the proposed SVR model has higher forecasting accuracy than the existing time-series methods. In addition, the conventional time-series model has high accuracy under proper curation of wind turbine operation data. Therefore, the analysis results reveal that data curation and weather information are as important as the model for wind power forecasting.

Water has been known as a substance that can extinguish fires. Water is not only easily sourced from nature, but it has been naturally used to extinguish forest fires because it does not cost anything. However, when rivers, reservoirs, streams, etc. are frozen in winter, it may be difficult to use water for extinguishing. For this reason, other countries are used to fire extinguishing agents that have higher extinguishing performance than water to reduce the extinguishing time and amount of water. In this study, the extinguishing performance of wildfire suppressants was evaluated in line with the trend of other countries’s forest fire extinguishing technology and the fire extinguishing agent system applied to the extinguishing equipment. As a result, when a fire extinguishing agent is applied to forest fire extinguishing equipment, it is possible to extinguish the fire with about 6-20% less than water, and the time required for extinguishing is reduced by about 6-14%. In addition, if a line-froportioner-type gun mixing device is applied to a forest fire extinguishing vehicle, it can be constructed without a separate structural change.
