EES is a battery-based technology to manage and regulate electrical power generated by heterogeneous non-permanent sources (e.g. renewables Wind & Solar). It also acts as a buffer to compensate Production-Consumption discrepancies. It is a key component of “Smart Grid” concept.
EES is spread over the entire grid, from the main high power generation devices (PV or wind farms) down to the industrial & residential installation having its own PV capability. In some cases, EV/HEV batteries are also considered as an EES component that may buffer power fluctuations.
Compensation of the constant fluctuations between low and high utilization necessitates large-scale electrical energy storage (EES) systems. These systems are key components in the smart grid network of the future. The requirement for efficient electrical protection of these systems is on the rise: electrical energy storage systems often have capacities of several hundred MWh and are subjected to a broad range of fault currents – from several 100 kA to a few hundred amperes (at operating voltages up to 1500 VDC).
Mersen, specialist for safety of electrical energy, is constantly working on solutions to answer the extreme demands on protection systems.
Mersen now offers protection for the entire Battery system: module, rack, section and container.
With the ABAT product series, Mersen introduces innovative protection systems that are optimized for the fluctuations inherent in renewable energy applications.
