The Energy Management System (EMS) communicates with power plants and substations, monitors the substations and plant operational status of the transmission and substation system for stability, continuity, real-time, and economy of power supply, and controls power plants and substations. Currently, the power exchange EMS communicates with power plants and substations based on the serial communication-based Distributed Network Protocol (DNP) 3.0 protocol. However, problems such as the difficulty of supply and demand of serial communication equipment and the lack of installation space for serial ports and modems are raised due to the continuous increase in new facilities to perform communication, including renewable power generation facilities. Therefore, this paper presents a TCP/IP-based communication method instead of the existing serial communication method of the power exchange EMS, and presents a security risk analysis that may occur due to changes in the communication method and a countermeasure to the security risk.

The purposes of this study which was conducted by studying the literature on Emergency Medical Dispatch System are to provide some developmental policies of quality management, pre-arrival instructions, priority dispatch protocols, training program for the dispatchers(Emergency Medical Dispatchers or EMDs) in Korea and to promote understanding emergency medical dispatching. The conclusions from this summarized as follows; (1) It is confirmed that there has been little study on the Emergency Medical Dispatch System in Korea, because for the first time, the real Emergency Medical Services were introduced into Korea in 1994, and the importance of the Emergency Medical Dispatch System has not been realized. (2) Only some squads are using a set of dispatch protocols, others aren't. (3) In spite of trying to introduce a new set of dispatch protocols, it isn't the priority dispatch system using a complete set of dispatch protocols which has key questions, pre-arrival instructions, mode & configuration based on patient assessment. (4) The EMS is unable to promote the service capacity by using quality management, because there is no medical control on the emergency medical dispatching and the EMDs. (5) There are no medical directors in the communications center who are in charge of the medical control to detect problems derived from the EMS and to solve them. (6) There are no systematic training program for the EMDs who are taking charge of dispatching. (7) Having a deep relation to the elements of the EMS, the emergency medical dispatching is subject to restriction of those elements.

In the Paris Climate Agreement, Korea submitted an ambitious goal of reducing the greenhouse gas emission forecast (BAU) by 37% by 2030. And as one of the countermeasures, a smart grid, an intelligent power grid, was presented. In order to apply the smart grid, EMS(Energy Management System) needs to be installed and operated in various fields, and the supply is delayed due to the lack of awareness of users and the limitations of system ROI. Therefore, recently, various data analysis and control technologies have been proposed to increase the efficiency of the installed EMS. In this study, we present a measurement control algorithm that analyzes and predicts big data collected by IoT using a SARIMA model to check and operate energy consumption of public sports facilities.

In an EMS (Electromagnetic suspension)-type Maglev (Magnetically-levitated) vehicle, the flexibility of the bogie frame may affect the acceleration of the electromagnet that is input into the control system, which could lead to instability in some cases. For this reason, it is desirable to consider bogie frame flexibility in air gap simulations, for the optimization of bogie structure. The objective of this paper is to develop a flexible multibody dynamic model of 1/2 of an EMS-type Maglev vehicle that is under testing, and to compare the air gap responses obtained from the rigid and the flexible body model. The feedback control system and electromagnet models that are unique to the EMS-type maglev vehicle must be included in the model. With this model, dynamics simulations are carried out to predict the air gap responses from the two models, of the rigid and flexible model, and the air gaps are compared. Such a comparative study could be useful in the prediction of the air gap in the design stage, and in designing an air gap control system.
