Short Description of Technologyclean energy and Faktor/AWE present the first TÜV certified megawatt storage system called . Themegamaxelectrical energy storage system based on battery energy storage technology includes state of art superiorbatteries: lithium-iron-phosphate batteries. An especially developed two-way, high-capacity inverter andtransformator (2 x 250 kW, 3-phase, 0.4 kV) is responsible for the loading of the battery blocks by the grid aswell as for feeding the grid with the storage system’s energy. The storage units can be operated and managedremotely via the AWE BSVPP monitoring and process control system (BSVPP: Battery Strengthen Virtual PowerPlant). Operating and managing is a geographically independent procedure. The equipment is going to be placedin a 40’ feet high sea container. The container includes all the major equipment, the control system and thecooling technology, which is capable to maintain the required temperature. The cooling technology is alsooperated by the control unit. Because of its standard size and design, the plant is mobile and can easily bemoved. But it is also applicable for stationary use inside as well as outside of buildings or halls.2. Main parameters of Storage Systemmegamax1 Built-in storage capacity 1 MWh2 In/output performance 500 kW3 Weight (batteries included) ~ 22 t4 Input/Output voltage (3 phase) 3*400/230 V5 External dimensions of the container 12,192 m*2,438 m*2,896 m (40"*8"*9,6")6 No. of built-in batteries 2*192 db (1000 Ah; 3,2V; monocell)7 Battery Management System (BMS) AWE self-developed8 No. of built-in inverter 2*250 kW, AWE self-developed9 Max. discharge time 2 hours10 Control BSVPP (Battery Strengthen Virtual PowerPlant) - AWE self-developed3. Main Storage ApplicationsI. The Lithium Energy Storage is very suitable for ancillary service purpose (control energy) because ofits short reaction time.II. It serves for interference filtering on medium and high voltage system level in order to preventdisturbances and damages of sensitive electronic equipments.III. The Storage System maintains uninterrupted power in case of electrical outage: UPS function!Because of the very short switching time (only milliseconds!) the availability of the changeovervoltage downstream and the availability of the changeover function are absolutely ensured.IV. The Storage System is able to feed in a defined idle power into the medium-voltage grid not only innormal operation, but also during a short breakdown of the voltage in the high or highest-voltagegrid.

The MW-Storage can be used as a mobile off-grid power station providing energy where normally isnone: in emergency cases, for out-door events, geological research areas, …)VI. Storages in combination with PV-parks, provide power during night time in order to keepmegamaxgoing the system connection with the surrounding distribution grid.4. Battery Technologies in comparison:Li-iron-phosphate batteries – a leading edge technologyOur Storage System is based on the Li-iron-phosphate battery technology. The overview shows why:Technology Advantages DisadvantagesModern lead-acidbattery1. Well known technology2. Cheapest battery (USD/Ah)1. Low energy density, relatively highspace requirements2. <1000 cycle lifetime3. High environmental impactNaS battery 1. Higher energy density compared toVBR and Lead-Acid2.
