What is battery energy storage system (BESS)?

The sharp and continuous deployment of intermittent Renewable Energy Sources (RES) and especially of Photovoltaics (PVs) poses serious challenges on modern power systems. Battery Energy Storage Systems (BESS) are seen as a promising technology to tackle the arising technical bottlenecks, gathering significant attention in recent years.

What are the benefits of a Bess system?

In addition, they can be considered as ideal areas of BESS deployment, as BESS offer a number of benefits including storage size, energy efficiency, faster response time, and low maintenance requirements compared to conventional generation sources, while they are well suited for lifelong RE installations.

How does the Bess work?

The management system of the BESS can be set by the user in order to perform the charging of the battery asset during a selected period of the day, instead of periods of PV production surplus, as aforementioned. In this way, the flexibility of the user regarding the purchase of energy from the grid (i.e. Energy Flexibility) increases.

Is Bess a distributed energy resource?

The study introduces BESS as a Distributed Energy Resource (DER) and delves into its specifics, especially within hybrid Photovoltaic (PV) and BESS setups. It covers various configurations and benefits of these hybrid systems, emphasising the role of BESS in enhancing controllable Renewable Energy (RE) integration.

Why do we need a Bess power system?

Moreover, it is an ancillary service that BESS can easily provide to the power system. Power demand and supply in the electricity grid have to be equal at all times.

Why do we need a Bess power grid?

BESS enables the storage of excess energy generated during peak production times, so we have a steady supply when renewable sources are not producing power. Modern power grids require flexibility to handle variable energy sources and consumption patterns.
