1 Large Hybrid(MW) EES (UPS, Emergency Electric Power, Demand Management) INCELL Co., Ltd

2 Overview Introduction Large Hybrid EES System feature Large Hybrid EES System composition product

3 Introduction 1.SAVEEN MG UPS & Demand Management UPS System accident Vital load voltage Demand Peak Shift/Peak Cutting Management (DM) General load voltage Discharge - Recharge

4 Introduction 2.SAVEEN MG Configuration Kepco system Vital Load General load EMS

5 Introduction 3.SAVEEN MG vs Previous UPS Series double-transformation structure (Previous UPS) Parallel single-transformation structure (SAVEEN) Strength Guarantee the quality of power on various power supply problems Strength High efficiency / Meet to demand management Drawba ck - Low efficiency / Price increase Drawback - Unable to control the out put voltage and frequency.

6 Large Hybrid EES System feature: Emergency Electric Power &Demand Management 1. A. Off-Line UPS Use high- speed switch to guarantee UPS - The feature of UPS(< 4msec ) : It is able to use for IDC and Data processing room -Option operation: Reduce the unnecessary power loss( 10% reduction) and prevent the life- shortening ( Two times lifespan) Normal condition Black out condition B. The function of Large and high output on Hybrid EES System : available uninterruptable function of large and emergency generator - It covers the specific supply range for large and emergency power supply and enlarge the time; UPS cannot guarantee them. - Supply non-interrupting ti electric source until operating the emergency generator: Bulk and high-speed, a large output

7 Large Hybrid EES System feature: Emergency Electric Power &Demand Management C. The effect on replacement of previous UPS 1) Off Line UPS - Optional operate: No power loss in general ( which included in high-efficiency energy products) - UPS is required the heavy power consumption which operates power rectifier for 24hrs 2) Use lithium battery : selective capacity & easy maintenance, long lifespan, flexible area of installation - Offer various capacities selection: From 5 minutes to 1 hour or more; with based on situation - The application of BMS / Battery monitoring :actively cope with emergency situation - It is effective in the space application side which it s volume is 30% less than the lead acid storage system - Guarantee the long -lifespan: the function of effective power management through over 5,000 times of charge and discharge. 3) Peak management available in general operation of EES System : - Advantages of electric charges reduction and return on investment ** 40% in installation rate of the total facilities required of UPS With combination of EES function, which h is a favorable position in return on investment t and cost of initial investment matter and others.

8 Large Hybrid EES System feature: Emergency Electric Power &Demand Management D. The time function of emergency generator linked to ATS switchover : The enlargement of the application range on emergency electric power 1) Guarantee the uninterruptible tibl power of emergency generator : the supplementation ti of the initial action ability of emergency generator - Blackout and other accidents: the correspondence function of uninterruptible power in golden time which is until operating emergency generator. - It is suitable for demand management business such as use of emergency generator 2) The control of operation of diesel generator for emergency : secure the emergency power capacity over 30min; which is available for blackout - The specific workplaces which are sensitive to the problem of installation, emissions and noise. 3) Use lithium battery with high output(4c~10c) - Guarantee the stability of emergency power with instant output function ** The installation size of emergency generator: 70,000 pcs in the whole country in Korea. / the total t generating capacity = 21GW volume

9 Large Hybrid EES System Composition 1. PCS product family for Large Hybrid EES System A. PCS(which guarantee of instant voltage ): STABLEEN_DVC - The guaranteed time for uninterruptible power: 3sec to 1 min. - Storing device: Super Capacity ~ use high-output with high power Lithium battery. - Main used place: semi-conductor production line, oil refining, fine chemistry and others which are required to cope with instant blackout. B. Off Line UPS + DM Hybrid PCS : SAVEEN_MG - The guaranteed time for interruptible power : 6 / 15 / 30 / 60mins or over, -Storing device : high-output( 1C ~ 10C ) with high power Lithium battery use. - The guarantee way of uninterruptible power : Static Switch (reaction velocity : < 4mS ) - Main service place : the place which include both UPS and emergency generator, the hospital, CCTV control center, IDC, base station, telephone company and other communication facilities. Additionally, Micro grid, power plant and power transmission. C. PCS which is possible to drive independently for blackout : SAVEEN_ES - Use of Dynamic Switch, independent drive for recovery from black out within only 3 sec. In general, which is available to use of DM as well as emergency situation, - Service place : ordinary factory, water supply, buildings and others which require electricity.
