BESS

2025-07-08T16:15:35Z

Youssefsan:

A '''battery energy storage system (BESS)''' is a combination of a [[battery]], power inverters, battery management system (BMS) and energy management system EMS. Other components may include: thermal regulation system,fire protection, electric protection, transformers. The goal is to provides energy services. Large and/or BESS may require electrical technician to maintain the electrical instalaltions and an operator for the energy management system/SCADA.

== Roles ==

The role of the BESS is store and release energy in order to provide services while respecting constraints. Some services may be competing and other complementary. This problem can be formulated as a mathematical optimization problem.

Typically BESS tend to solve problems related to
* distribution and transmission grid. Grid have to respect at all time two constraints
** supply and demand must be balanced
** transformers, cable and lines can sustained a limited power
* environmental: reducing carbon footprint
* power supply continuity: emergency back-up and black start
* power quality
* economical: lower/deffer investment, reduce operating costs

Some of these goals are complementary and can be combine. We speak then of [[value stacking]]. Some are competing.

Services can be grouped in various category:
* emergency power and off-grid operation
* black start
* maximizing consumption of locally produced energy and reducing curtailment of locally produced energy.
* ensuring balance of supply and demand at various time- and geographical time-scales: energy arbitrage (aka time of use), imbalance reduction, frequency regulation (a type of ancillary service)
** energy arbitrage (or time of use), in Europe this can be traded on power exchanges (e.g. Nordex, Epex) via day-ahead and intra-day prices or via dynamic energy contract (in this case the energy supplier will trade directly or indirectly on the power exchanges.
* ensuring the transmission capacity of the national, regional, or local grid are respected. This includes capacity tariffs in Europe (know as demand charge in the US), contractual power, grid upgrade def feral.
* power quality. Ensuring voltage and reactive power are within operating limits.

These services may be more or less mature depending on the country and local situation.

Youssefsan: /* Other companies */

An '''electric battery''' is a device that transform chemical energy into electric energy in both directions. It serves to store electric energy by transforming electric energy into chemical energy when it is relatively easy/cheap and release (by transforming back chemical energy into electric energy) it when it is relatively expensive or more needed.

Battery are part of battery energy storage system ([[BESS]]): a combination of a battery, power [[inverter]]s, battery management system ([[BMS]]) and energy management system [[EMS]]. Other components may include: thermal regulation system,fire protection, electric protection, transformers.

== History of batteries==

Lead-acid battery, the first rechargeable battery, was invented in 1859 by the French physicist Gaston Planté. In 1881, the French chemical engineer, Camille Alphonse Faure developed an improved version of lead-acid battery.

In 1866, French electrical engineer developped a non-rechargeable battery with a manganese dioxide cathode and zinc anode.

In the 1990s, [[Sony]] commercialized Lithium Ion recheargeable batteries.

* [[SIB]] aka NIB: sodium ion
* [[VRB]] aka VFB: vanadium (redox) flow

In 2022, LFP, NCA and NMC622 were among the most common chemistries used for electric cars in the European Union [JRC 1]
