In this blog, we will explore these critical aspects of energy storage, shedding light on their significance and how they impact the performance and longevity of batteries and other storage systems. State of Charge (SOC) is a fundamental parameter that measures the energy level of a battery or an energy storage system.
EV charging and discharging scheduling will result in additional challenges within power grids. With the growing adoption of EVs and RESs such as PVs and WP in SGs, there is an increasing need for accurate predictions and joint scheduling optimization to improve system stability and reliability.
Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery’s total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%. The higher the DOD, the more energy has been extracted from the battery in that cycle.
A fundamental understanding of three key parameters—power capacity (measured in megawatts, MW), energy capacity (measured in megawatt-hours, MWh), and charging/discharging speeds (expressed as C-rates like 1C, 0.5C, 0.25C)—is crucial for optimizing the design and operation of BESS across various applications.
With the rapid increase of EV, the increase of EV charging stations have a significant impact on the distribution networks [99, 101, 170] in loads and voltage flow, power losses, phase imbalance, voltage and frequency regulation, power quality, and reliability .
