This article will focus on battery energy storage located within electric distribution systems. This lower-voltage network of power lines supplies energy to commercial and industrial customers and residences that are usually (but not always) found in urban and suburban centers. The notable exceptions are electric cooperatives and
Substations Substations are found at points on the network where circuits come together or where a rise or fall in voltage is required. Transmission substations tend to be large facilities containing equipment such as power transformers, circuit breakers, reactors and capacitors. Diesel generators and compressed air systems are also found there
The growth in volatile renewable energy (RE) generation is accompanied by an increasing network load and an increasing demand for storage units. Household storage systems and micro power plants, in particular, represent an uncertainty factor for distribution networks, as well as transmission networks. Due to missing data exchanges,

The SSVT is directly connected to the HV network and provides power to the panel within the substation, or to remote loads directly supplied for the HV service. SSVTs can provide output voltages from 120 V to MV levels (contact factory for specific output voltages). Power levels available range from 10 kVA to 167 kVA single phase supply for all
The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites, etc.) via lower voltage lines.
More extended periods of energy storage are often provided by high-density batteries, pumped hydro energy storage, compressed air energy storage (CAES), or hydrogen storage. These storages, capable of transmitting energy from hours to even months, are suitable for energy management applications such as arbitrage, pick
