Examining the Inside of a BESS: What It Is and How It Functions

It's important to understand a few basic ideas about Battery Energy Storage Systems (BESS) and how they work before getting too technical. First, the term Battery Energy Storage System (BESS) refers to an electronic Power Conversion System (PCS), like an inverter, combined with a battery. Distribution Network Operators (DNO) and Transmission System Operators (TSO) view the PCS as the main topic of interest and are less concerned with the particular battery type.

Modern lithium-ion batteries, cryo-batteries, flow batteries, and even more sophisticated choices can be used in place of more traditional automotive batteries. How quickly chemical energy can be transformed into electrical energy and how much storage capacity can be achieved depend on the type of battery that is selected.

Second, there is an important, but frequently misunderstood, distinction between power (MW) and energy (MWh). Under the restrictions set by the inverter rating and system architecture, a BESS rated at 1MW & 1MWh can deliver 1MW for an hour, 0.5MW for two hours, or 0.25MW for four hours. Because it controls the main power flows in their network, DNOs place a strong emphasis on MW capacity.

This leads us to the third point: fluctuations in power. Heat maps from DNOs show simple MW flow, but how well the network can withstand large power fluctuations is less obvious and usually requires careful examination.

The term "power swings" describes how quickly the BESS switches between import and export, and vice versa. The shift is gradual for services like power arbitrage, meaning power swings are not greatly affected. Strong power systems may face difficulties when dealing with 50MW BESS power swings, which can reach 100MW/s for quick response services like DC. This is because a 50MW BESS may go from full export to full import in less than a second. G99 forms ask regarding the BESS's ramp rate for this reason.

Finally, it is imperative to recognize that a BESS can provide both reactive and active power, thereby helping to control voltage on the DNO network. A BESS that is properly sized can provide 20MW of active power and 20MVAr of reactive power.

Knowing the planned services and local restrictions is essential for grid applications for a BESS. Less focus is placed on the MWh rating since DNOs and National Grid are more interested in learning about the MW capacity, worst-case power swings, and reactive power flow capability.

An Energy Storage System's Battery System Structure

Several essential components make up a battery energy storage system. Every component is essential to maintaining the BESS and the batteries safe, functional, and cool. Here's a picture showing how these components are connected within the BESS.

Observes and Regulates

• System for managing batteries (BMS)The Monitors & Control module, commonly known as the BMS (Battery Management System), is in charge of managing the storage device. The electronic circuitry in this real-time monitoring system will keep an eye on the battery's condition. Moreover, it controls the charging and draining process, sounds an alarm, safeguards the battery, and maximizes the performance of battery modules and cells to ensure their stability, safety, and dependability. The three levels of design of TROES' exclusive BMS are the master battery management, sub-battery management unit, and cell supervision circuit.
• Controller for Local MicrogridsDepending on the needs of the project, the microgrid controller is offered as an optional component. Distributed energy storage systems are monitored, dispatched, and managed by the microgrid controller. Moreover, it provides users with real-time information on working status, operating parameters, anomalies, and running expenses and revenue analysis of the energy storage system.

Control of Temperature

• Sensor and Control System for the EnvironmentThe environment control module receives a signal from the environmental sensor if it finds any unusual surroundings for the BESS. This comprises, among other things, smoke, floods, and door sensors. The precision air conditioner, air conditioning duct, and automated control system that make up the environment management module are what give batteries the optimal temperature and humidity conditions when they are being charged and discharged.
• System for Fighting FiresIn order to prevent electrical fire within the container, the fire suppression system is designed to mitigate any risks associated with the battery charging and discharging process, ensuring the energy storage system operates safely.

System for Conversion of Power (PCS)

For the purpose of transferring electrical energy from DC to AC and vice versa, a device known as a Power Conversion System (PCS) is used. Battery and solar panel outputs are DC, although most loads are AC. In addition to far more intricate systems, this might be as basic as a transformer to adjust the voltage of AC power. When considering PV inverters versus PCS energy storage, the former is a bi-directional inverter/charger.

Switch, Transformer, and Breaker

A DC switch and an AC breaker are located between the PCS and the storage device and the AC transformer, respectively, for added security. Following the DC switch, the solar energy DC input or DC output load can be linked to the system. One important external component that guarantees the BESS's output meets the client's AC voltage requirements is the transformer.

Coverage

Both indoor and outdoor cabinets and containers are available to customers. Though they can be tailored to meet the specific requirements and space constraints of the project, enclosures are available in a variety of preset sizes. A container or cabinet houses every part of the battery energy storage system, with the transformer being the exception.

Storage

The main part of a battery energy storage system is the storage device. The energy charged from renewable or grid energy is stored in the storage device. The schematic of our storage device is shown below, along with an explanation of each component's function and system integration.

• Cells and Mono-CellThe simplest type of unit is the mono-cell, which is a single LiFePO4 sealed aluminum battery unit. After being assembled, these mono-cells are formed into the cell. To generate a voltage and current, a single anode and cathode divided by electrolyte is called a cell. One or more cells can make up a battery. The battery cells are then assembled into a battery module by connecting them either in parallel or series.
• ModuleThe module is made up of multiple individual battery cells that are joined electrically and enclosed in a shell to form the module. After that, these components are assembled and fitted into our unique battery packs.
• Energizer PackA collection of one or more identical battery modules or individual battery cells is called a battery pack. In order to provide the required voltage, capacity, or power density, they can be arranged in series, parallel, or a combination of the two.
• Power SourceA string-like structure made of numerous battery packs connected in series makes up the battery system. The maximum number of battery packs that can fit in a rack is restricted by the DC voltage and certification limits. The battery system is made up of one or more of these battery strings.

Putting It All Together

All things considered, a BESS uses battery storage technology to store energy that is obtained from the electrical grid or renewable energy sources like solar and wind. After that, batteries drain and release the energy when needed for a number of uses, including power interruptions and peak demand.

Different types of batteries, including as lithium-ion, lead-acid, nickel-cadmium, and others, can be used with BESSs; we'll go into more detail about them later in the post. Specific technical characteristics of each battery type identify BESS uses and impact battery energy storage efficiency. The primary features of batteries include:

• Ability to store:This is the quantity of power that can be found in a BESS or the amount of electric charge that a battery can store.
• Power: This setting establishes the battery's power output or the maximum power output that a BESS can produce.
• Efficiency of a round trip: This shows how much energy a battery delivers during a discharge compared to how much energy it receives during a charge cycle.
• Discharge Depth (DoD): This displays the percentage of a battery's energy that has been used up compared to its total capacity.
• Lifetime: This can be characterized as the quantity of energy a battery can provide over the course of its lifespan or the number of cycles of charge and discharge (battery throughput).
• Safety: This is a crucial feature that demonstrates, among other things, how well the battery complies with safety regulations regarding its chemistry.Other features that characterize the performance of storage battery systems exist in addition to the battery specs listed above. Response time, for instance, is the amount of time required by a BESS to transition from an idle to a fully operational state. Peak velocity is the speed at which the power output of the system can be ramped up or down, accordingly.

Conclusion

A BESS is a multi-component energy storage system that can be used for peak shaving, energy arbitrage, or black starts. It can store different amounts of electrochemical energy.

Large-scale industrial operations, utility grids, smart homes, and other commercial and domestic applications can all benefit from the lightweight and reasonably priced nature of BESS thanks to advancements in battery technology. Green energy and battery storage can work together to provide a dependable, self-sufficient power source for buildings, villages, towns, and even entire islands.
