As environmental issues have been become critical concerns of business, many domestic small and medium enterprises(SME's) are rapidly accepting environmental management systems(EMS) that confirm ISO 14001 guidelines. The purpose of this paper is to present the results of an empirical study carried out on a sample of certified SME's with the aim of identifying obstacles encountered in adopting ISO 14001 standards and the impact of environmental systems on corporate performance after implementation of the ISO 14001 registration process. Data from this study show that the vast majority of respondents reported environmental improvements related to the implementation of an ISO 14001 EMS, especially in the area of employees' participation of the environmental management and responsibilities for reducing negative impacts, energy and resource conservation, materials reuse, and raising top management commitment. The greatest obstacles for implementing the ISO 14001 standard are lack of cooperation and a scarcity of resources such as personnel, money, and time. Results of this study serve as a reference point understanding the problems in the implementation of ISO 14001 in other small and medium firms.

KEPCO has completed the installation and demonstration of a 52 MW battery energy storage system (BESS) for frequency regulation. Especially, 24 MW BESS is for Automatic Generation Control (AGC) in Shin-Yongin substation. Recently, KEPCO Research Institute has operated it connected to EMS of KPX. This paper discussed the operation strategy of EMS through a study on using 24 MW BESS in AGC operation and propose the improvement of AGC target. It is expected that this paper helps a safe and reliable operation and control of ESS for AGC through its continuous update.

This paper presents the modeling of hybrid railway vehicles with hydrogen Fuel-Cells (FCs)/battery using a rule-based algorithm. The driving power of traction system is determined with the speed-torque curve by operation area of the electric machine and the electrical systems are modeled. The demanded power of electrical systems is set with the energy management system (EMS). The consumption of hydrogen is effectively managed with the subdivided operation region depending on the state of charge (SOC). The validity of the modeling is verified using MATLAB/Simulink.

Needs for Smart Grid development are increasing all over the world as a solution to its problem according to depletion of energy resources, climatic and environmental rapidly change and growing demand for electrical power. Especially decentralized power is attracting world's attention. In this mood a new era for a unit scale of decentralized power environment is on its way in building. However there is a problem to have to be solved in the uniformity of power quality because the amount of power generated from renewable energy resources such as wind power and solar light is very sensitive to climate fluctuation. And thus this paper tries to suggest an energy management method on basis of real time monitoring for meteorological data. In the current situation of lacking in USN-based killer application in Smart Grid field, this paper proposes the USN-based DER management system which collects the meteorological data and control power system througout utilizing wireless sensor network technique this business. This communication technique is regarded to be efficient in aspects of installation cost and tits maintenance cost. The proposed EMS model embodies the method for predicting the power generation by monitoring and analyzing the climatic data and controling the efficient power distribution between the renewable energy and the existing power. The ultimate goal of this paper is to provide the technological basis for achieving zero-energy house.

With the increasing interest of energy efficiency, several buildings and factories begin to monitor energy usages with a built-in energy management system. However, the built-in energy monitoring system does not reflect the dynamics of buildings and factories energy usage. To overcome the latter, we deploy several sensors to monitor the dynamics of buildings energy usage patterns. In this paper, we are proposing a framework of a sensor based energy monitoring system. Based on our limited experiments, we can monitor power usages by a person, device and time period. As a result, we can plan a better energy usage and improve energy efficiency by the monitored energy usage profile data.

Recently, the use of ESS facilities has been increased under the government's energy policy and at the same time, the various accident incidents such as fire and explosion occurred. Currently the ESS is installed as integrated ESS which includes PMS(: Power Management System), However, when the accident occurs, this system has high possibilities of losing the data due to oxidization, and the administrator cannot respond promptly. Therefore, in this paper, by constructing a separate WAS and data storage, it is possible to separate the main functions of the conventional system, to enable external EMS operation, and at the same time to quickly respond to the cause and cause of the accident occurrence. We will propose the development of a standalone PMS that is possible to respond.

최근 전자설비를 바탕으로 한 고도 정밀산업의 발달과 국민 생활수준 향상은 전력의 고품질화와 고신뢰성을 절실히 요구하고 있다. 즉, 전력이라는 에너지를 수용가에게 공급하는 것으로 그치지 않고 전력의 품질(주파수와 전압을 규정값 이내로 유지)에 엄격한 제한을 두어야 함은 물론 공급의 신뢰성, 즉 중단없는 전력 공급이 요구되고 있다. 이러한 미래의 전력 경영상의 어려운 과제를 해결하기 위하여 지금까지 이용되어 왔던 자동 급전시스템(ALD:Automatic Load Dispatching)을 최신 기술이 집약된 급전종합자동화시스템(EMS:Energy Management System)으로 교체운용할 계획이다. 지금까지의 분산 설차 운용되어 왔던 지역급전 시스템(SCADA)과 한강수계제어시스템을 EMS시스템과 연계하여 운용함으로써 전력계통을 종합 감시 제어하게 될 것이다.
