The energy is usually stored in batteries for specific energy demands or to effectively optimize cost. ESM can store electrical energy and supply it to designated loads as a primary or supplementary source. Moreover, it provides a stable and continuous power supply regardless of the supply source status. Voltage and frequency regulation can also be improved by using ESM modules. ESM contains inverters that rectify the AC energy into DC to store in the batteries and then invert the DC energy into AC energy. The energy inverted into AC power can be connected to the electrical network at low (<1000 Volts) or medium voltage (<40.5 kV). ABB provides the necessary electrical, protective and monitoring equipment along with the battery system to utilize the batteries safely with a pre-designed system designed to meet ANSI, IEC, and other international standards. This will guarantee a high level of energy continuity and superior power quality in a safe and cost effective module. The ESM enclosure is engineered to maintain the internal temperature within the design limits as well as provide protection. Different temperature classes and protection degrees are available according to the application and size. The degree of protection for the ESM enclosure is designed according to IP or NEMA standards. ESM is available in several capacities with individual modules up to 4 MW and an output voltage range from 120 volts to 40.5 kV at 50 or 60 Hertz, single or three phase system. Descriptive bulletin | ESM Energy Storage Modules 3 Applications ESM has different applications within the distribution network aiming to improve the quality and continuity of the power at optimal cost. The main applications of the ESM are: Load shifting / time of use management: The practice of altering the pattern of energy use so that on-peak energy use is shifted to off-peak periods. Graph number 1 below shows a peak shaving/load shifting application. The blue line shows the customer demand profile, which is peaking late in the afternoon. The purple line shows what the Energy Storage Module is doing, charging early in the morning when the demand is low and discharging when the demand is peaking. The yellow line shows the net effect on the electrical grid (a lower demand peak and a more balanced demand). Benefits: a) Reduces the cost of energy by charging the system with low priced energy and discharging later when the energy prices are high b) Shifts renewable generation to peak times, allowing for participation in capacity markets as a dispatchable resource, smoothing the renewable output Renewable energy smoothing or ramp control: Reduces the impact of quick changes in renewable generation levels. It can be used to ensure that wind-farm ramp-rates (MW/min) are kept within design limits and to eliminate rapid voltage and power swings on the electrical grid. Peak shaving: Peak shaving is related to Load Shifting. Both are part of the demand management in which the ultimate goal is to increase the load factor. Graph number 2 on the next page shows a renewable smoothing ramp control application. The wind farm power is shown in orange. The ESM system power is shown in blue. The black line shows the net effect on the electrical grid (a gentler ramp slope and lower variability). Benefits: a) Commercial and industrial customers reduce their energy charges by improving their load factor b) Utilities reduce the operational cost of generating power during peak periods (reducing the need for peaking units) c) Investment in infrastructure is delayed because they have flatter loads with smaller peaks. Renewable capacity firming: Helps maintain the power output at a committed (firm) level for a period of time.

The system supports the frequency on the grid and keeps a state-of-charge of approximately 50%. ESM is an attractive option for this application due to its rapid response time. Spinning reserves: In this application, the ESM remains charged and responds in case of a generation or transmission outages. Depending on the application need, the system can respond within milliseconds or minutes. The ESM supplies power until the back-up generator is started and running. This application allows the generators to work at optimum power, without the need to keep idle capacity for spinning reserves. The system can also eliminate the need of having back-up generators running idle. Delay in line upgrades: An ESM can be placed electrically downstream in a congested transmission system, helping to reduce the overloads in the lines and delay investments in line upgrades. Power quality: An ESM helps protect the loads further downstream against short-duration events that affect the quality of power delivered to the load. Voltage and VAR support: An ESM can help to maintain the grid voltage by injecting or absorbing reactive power (VAR) Railroad applications: Accelerating a heavy train can expose the grid to a peak load that traditionally necessitated extensive investment in capacity expansion. An ESM unit can supply the required acceleration power that is taken from the most recent deceleration. Outage management: ESM can provide power for short periods of time to a network reducing or eliminating the effect of a temporary outage.
