Energy storage includes equipment and services for electrochemical (batteries), thermal, and mechanical storage. The United States is one of the fastest growing markets for energy storage in the world, giving U.S. companies expertise in
Uninterruptible Power Supplies with hybrid storage system Uninterruptible power supplies with batteries as storage source provides good performance during grid interruption and blackout by suppling instant backup energy. However batteries cannot provide backup for a very long period of time and have limited charge/discharge cycles.
Besides, low transients response time from online mode to battery powered mode and vice versa, unity power factor, high reliability, high efficiency, low cost, low weight, and small size, etc. are other essential considerations in the UPS system. Broadly the UPS can be classified as the Static UPS system and Rotary UPS system.
Block Diagram of hybrid energy storage UPS system. The Fuel cell is the main source of energy. Batteries and super-capacitor act as secondary source of energy. Fuel cell is linked to DC-Bus through the DC–DC converter while all other sources are linked to the common DC-Bus through bidirectional converter.
Such are the basic conditions for energy storage to be included in the cost of transmission and distribution of electricity. Energy storage is of vital importance to the energy transition. The opening of the power market can help elevate energy storage to become a natural core part of the power market.
According to the IEEE standard ANSI/IEEE 446–1987, minimum power factor is 0.8 at the rated load and harmonics content less than 5% is preferred for the input rectifier of the UPS system. Table 8. Typical 3-Ø UPS System Specification by ANSI/IEEE 446–1987. Fig. 27. Input Voltage and Current waveform.
However the transformer based UPS are more expensive than transformer-less UPS system. Without input and output transformer, the cost of the transformer-less UPS system can be reduced to 30% or even more. Also the size and weight can be reduced to 50% in transformer-less UPS system as shown in the Table 2.
