본 논문에서는 한국형 에너지 관리 시스템의 네트웍 해석 소프트웨어의 하나인 휴전계획 프로그램의 개발에 대해 다루었다. 휴전계획은 장단기의 계통 설비 휴전에 대한 데이터베이스 관리 프로그램으로 계통 해석용 소프트웨어들에 정보를 제공한다. 휴전계획 프로그램의 개발을 위해 현행 휴전 절차를 검토하였으며 이를 통해 사용자 요구사항을 반영한 데이터베이스를 설계하였다. 휴전 계획 프로그램의 특성상 여타의 다른 EMS 용 어플리케이션과 달리 화면 처리 및 휴전정보 처리를 위한 독립적인 실시간 어플리케이션과 데이터를 필요로 하므로 이를 위한 아키텍쳐를 설계하였다. C++ 및 ANCI C를 사용하여 구현하였으며 한국형 EMS 시스템의 실시간 환경하에서 시험하였다.

Hybrid power storage system with emergency power function for demand management and power outage minimizes the investment cost in the building of buildings and factories requiring emergency power generation facilities, We propose a new business model by developing technology that can secure economical efficiency by reducing power cost at all times. Normally, system power is supplied to load through STS (Static Transfer Switch), and PCS is connected to system in parallel to perform demand management. In order to efficiently operate the electric power through demand forecasting, the EMS issues a charge / discharge command to the ESS as a PMS (Power Management System), and the PMS transmits the command to the PCS controller to operate the system. During the power outage, the STS is rapidly disengaged from the system, and the PCS becomes an independent power supply and can supply constant voltage / constant frequency power to the load side. Therefore, it is possible to secure reliability through verification of actual system linkage and independent operation performance of hybrid ESS, By enabling low-carbon green growth technology to operate in conjunction with an efficient grid, it is possible to improve irregular power quality and contribute to peak load by generating renewable energy through ESS linkage. In addition, the ESS is replacing the frequency follow-up reserve, which is currently under the charge of coal-fired power generation, and thus it is anticipated that the operation cost of the LNG generator with high fuel cost can be reduced.
