BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy management system for railroad stations,

The present invention relates to an energy management system, and more particularly, to an energy management system of a railroad history using an energy storage system so as to participate in a demand resource management market of Korea Power Exchange.

Increasing attention has been paid to energy efficiency and energy efficiency due to government regulations to improve energy efficiency and reduce greenhouse gas emissions, increased energy cost burden, and insufficient power supply. To conserve energy, sustainable and effective systematic tools of practice are needed, but until now there has been no satisfactory means. In order to conserve energy, it is necessary to find out where and how much energy is used, and to find a wasted factor and a powerful means to find out and implement improvement measures.

An energy management system (EMS: Energy Management System), which provides energy flow monitoring and control functions as a means for such demand, is attracting worldwide attention. This energy management system is an integrated energy management solution that optimizes energy use by analyzing aggregate data and real-time monitoring of energy use based on hardware, software and ICT-based monitoring and control technology.

Recently, Energy Storage System (ESS) has attracted much attention. Energy storage system refers to a storage device that stores energy as a battery so that it can be taken out at any time. Since electric energy so far has a difference in production and storage, production has to be moved together in using electric energy. The system is a system for effectively storing and using energy, allowing for energy production.

The Korea Electric Power Corporation (KEPCO) estimates that if the contracted capacity is reduced by the contracted capacity (ESS operation capacity) in the event of a reduction event, the compensation is compensated by estimating that the power generation has been reduced.

On the other hand, the existing urban railway supplies electric power to the electric railway rooms of two or three historic railway stations without substations in the history of substations, and the energy saving is achieved only through replacement of high efficiency and low power equipment such as LED.

Therefore, it is necessary to apply energy management system and energy storage system to the railway history so that it can participate in the demand resource management market of Korea Power Exchange.

A related prior art document is Korean Patent Laid-Open Publication No. 10-2012-0128313, which discloses a technique relating to an energy management apparatus.

Korean Patent Laid-Open Publication No. 10-2012-012813 (entitled " ENERGY MANAGEMENT DEVICE AND ENERGY MANAGEMENT METHOD, AND ENERGY MANAGEMENT SYSTEM WITH ENERGY MANAGEMENT DEVICE, " Published Date: November 27, 2012)

It is an object of the present invention to provide an energy management system for a railroad history using an energy storage system so as to participate in the demand resource management market of Korea Power Exchange.

According to an aspect of the present invention, there is provided an energy management system for a railroad history using an energy storage system, which is connected to a power system of a railroad history to charge or discharge electric power, Supplying energy storage system; And an energy management system communicatively coupled to the energy storage system and the KEPCO iSmart systems to control the energy storage system, wherein the energy management system is configured to receive power usage data of the railroad history from the KEPCO iSmart system Receives the input and analyzes the maximum load power, and causes the energy storage system to discharge at the time of using the maximum load power.

Here, the energy management system calculates a common base line (CBL) based on the analysis of the electric power usage pattern of the railroad history, and the energy storage system discharges the electric energy stored in the common base line .

At this time, the energy management system calculates the CBL (Common Base Line) in units of 15 minutes.

According to the energy management system using the energy storage system according to the present invention, power usage peak can be avoided and electric power usage fee can be saved.

2 is a diagram illustrating a screen of a display device according to an embodiment of the present invention.
3 to 6 are views for explaining a peak power avoiding method of an energy management system using an energy storage system according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to illustrate the present invention in a manner that will be readily apparent to those skilled in the art, And this does not mean that the technical idea and scope of the present invention are limited.

Hereinafter, an energy management system for railroad history using an energy storage system according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an energy management system using an energy storage system according to an embodiment of the present invention. FIG. 2 is a view showing a screen of a display device according to an embodiment of the present invention, 6 is a view for explaining a peak power avoiding method of an energy management system using an energy storage system according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, an energy management system 100 using an energy storage system according to an embodiment of the present invention is connected to a power system 400 of a railroad history to charge or discharge electric power, An energy management system 300 communicatively coupled to the energy storage system 200 and the KEPCO iSmart system 500 to control the energy storage system 200, . ≪ / RTI > And a communication network 600 that communicatively connects the energy storage system 200, the KEPCO iSmart system 500, and the energy management system 300.

The power system 400 may include a railroad historical substation and a railroad history electric room.

In order to supply 22.9kV AC with electric power from Korea Electric Power Corporation (KEPCO), the railway substation uses a rectifier to supply 1,500V of electric power for electric vehicles, electric power for general electric facilities such as lighting, AC three phase 6,600V (22,900V) power is converted and supplied.

The railway history electric power room converts 6,600V of three phase AC three phase supplied from a railroad history substation into three phase 380V and supplies power to the energy storage system 200.

The communication network 600 may be the Internet. Here, the communication network 600 is not limited to the Internet, and may be a wired communication network or a wireless communication network.

The energy storage system 200 and the energy management system 300 may include a gateway G for communicating with each other through the communication network 600.
