  • This study is to analyze women's power in family to be related to Anbang, kitchen, dining room, and utility room planning in a unit plan of condominium apartment housing in rural area Data were collected 194 unit plans from 9 eastern regions of Kungi-Do. The results are as followed: 1) Anbang reflects the women's power on changing its space character into mater bedroom, the highest hierarchy in private zone, and planning a dress room in it. 2) Dining room and kitchen is openly centered on the unit plan, but kitchen is still only women's working space for family and agriculture depended on literature review. Dining space is not activated family interaction, so it is not different from urban apartment housing. However, its location and character are changed, and its hierarchy is relatively higher with women. Dining room and kitchen tend to plan visually separated after 2001, so its trend seems to establish women's territory at home. 3) Whole family can't be easy to access utility and back balcony close to kitchen, and these spaces are functionally separated for women's house work. This design trend seems to establish for women's area. 4) Finally, women's power seems to be effective in house working area including kitchen space depended on results. Also, these results from rural condominium apartment are similar to urban ones in previous study.

  • In this paper, Optimal operation plan through load analysis of industrial end-user is suggested. It calculated economic feasibility of ESS with detailed power lad analysis and conditions. Generally, if the latest maximum power is less than 30% of contracted power, it can not be peak shaving operation plan. and if the peak load level stays stead for 24 hours, it is difficult peak shaving for ESS. In addition to, When the peak load is occurred in summer or winter, a hybrid operation method combining the peak shaving plan and the time shift method is proposed. Therefore, When ESS is installed in industrial electrical customer, it is achieved best effect through the optimal operation plan.

  • The facilities of electric power plant which were constructed in and after the 1960's are superannuated in these days. We are expanding them applying an incressary to secure a safe plan for them. In this study, for a feasibility of management plan in electric power structure, a RC test prame was manufactured for monitoring and calculation of variation using close range photogrammetry. On the basis of this data, monitoring and calculating of variation in soil wall building site were carried out. Also a survey and analysis of a influence which occured to a structure near by exactitude site. All of these afford data for a management plan in electric power structure.

  • With the benifit of telecommunication and IT technologies, Real-time Power system analysis having been gradually progressed. The power system become more complex due to the gradual increment of power demand. We analyze the problems in power system operation, by the use of PSS/E(power flow, fault and transient stability study) and VSAT for voltage stability. The results of establishment of power system operating plan and countermeasure are described.

  • The Korean government views coal-fired power plants as the key cause of the fine dust generation, and is developing an energy policy to replace and demolish old coal-fired power plants. According to the Eighth Power Supply Base Plan (2017-2031), the maximum power capacity in 2030 is expected to be 100.5GW, which is 17.9% higher than the current level (85.2GW). The plan aims to reduce the facility size and power generation ratio from nuclear and coal resources to even lower levels than today, and to rapidly expand power generation from new and renewable energy. Despite that, the proportion of coal power generation is still much higher than other resources, and it is expected that the reliance on goal will maintain for next several decades. Under such circumstances, the development, supply, and expansion of clean coal technology (CCT) that is eco-friendly and highly efficient, is crucial to minimize the emission of pollutants such as carbon dioxide and fine dust, as well as maximize the energy efficiency. The Korean government designated the Yong-Dong Thermoelectric Power Plant in Gangneung to develop clean coal power generation, and executed related projects for three years. The current study aims to suggest a plan to develop parts, technologies, testing, evaluation, certification, and commercialization efforts for coal-fired power generation, In addition, the study proposes a strategy to vitalize local economy and connect the development with creation of more jobs.

  • ESS is an essential requirement for resolving power shortages and power demand management and promoting renewable energy at a time when the energy paradigm changes. In this paper, we propose a cost-effective ESS Peak-Shaving operation plan through load and solar power generation forecast. For the ESS operation plan, electric load and solar power generation were predicted through RMS, which is a statistical measure, and a target load reduction guideline for one hour was set through the predicted electric load and solar power generation amount. The load and solar power generation amount from May 6th to 10th, 2019 was predicted by simulation of load and photovoltaic power generation using real data of the target customer for one year, and an hourly guideline was set. The average error rate for predicting load was 7.12%, and the average error rate for predicting solar power generation amount was 10.57%. Through the ESS operation plan, it was confirmed that the hourly guide-line suggested in this paper contributed to the peak-shaving maximization of customers.Through the results of this paper, it is expected that future energy problems can be reduced by minimizing environmental problems caused by fossil energy in connection with solar power and utilizing new and renewable energy to the maximum.

  • Making deicing countermeasure plan against snow accretion on power line is a very complicated problem, which should take into account both the possibility of accidents due to snow accretion on power line and the stable operation of power system. As knowledge engineering can be a good solution to this field of problems, a prototype expert system to assist power system operators in forecasting snow accretion on power lines and making a list of all the feasible and effective deicing countermeasures has been developed. The system has been remodelled into a fuzzy expert system by adopting fuzzy rulebase and fuzzy inference method to systematically process the fuzziness included in the heuristic knowledges. Simulation results based on the past snow accretion accident data show that the proposed system is very promising.

  • While everyone who uses electric power desires perfect frequency, voltage, stability, and reliability at all times, this cannot be realized in practice. The supplying utility cannot be expected to provide a perfect power supply because many of the causes of power supply disturbances are beyond the control of the utility. The outage happens but due to many reason. The electricity equipment requires consequently the emergency power supply. We classify the subordinate for quick supply of the emergency power supply and must grope the supply plan. We will find out in this paper through the case study about the emergency power efficient operation plan.
