What is Bess & how does it work?

Various stakeholders can use BESS to balance, stabilize and flatten demand/generation patterns. These applications depend on the stakeholder role, flexibility service needed from the battery, market opportunities and obstacles, as well as regulatory aspects encouraging or hindering integration of storage technologies.

What is a Bess battery?

Since there is a need to ensure longer period of power supply, the considered type of BESS is sodium-sulfur battery (NaS battery). This type of BESS is often called “energy-intensive” due to their possibility of discharging up to 6 h. The case study analyzes two scenarios: (a) a small capacity BESS and (b) a large capacity BESS.

Who is implementing Bess?

BESS is experiencing a flourishing implementation thorough multiple stakeholders ranging from private end-users, through distribution and transmission system operators to large power plant operators. Governments worldwide stimulate new investments into BESS to preserve security of the future power system.

What is the most researched system-level application of Bess?

The most researched system-level application of BESS is energy arbitrage. The methodology in [ 15] presents a determination of the size and location of BESS devices modeled for spatio-temporal energy arbitrage.

What are the different types of Bess applications?

All these applications can be categorized in three main groups: system-level applications, transmission and distribution grid applications and end-user applications. System-level applications are services that a BESS can provide to the power system regardless of its location in the system.

Should a prosumer install a Bess?

Generally, installation of a BESS is more reasonable when the prosumer already has PV installed. The final case study addresses the issue of reducing power and energy payments, as well as connection cost for an EV charging station coupled with a BESS. Here, small BESS provide best results due to peak shaving services they provide.
