Designers of utility-scale solar plants with storage, seeking to maximize some aspect of plant performance, face multiple challenges. In many geographic locations, there is significant penetration of photovoltaic generation, which depresses energy prices during the hours of solar availability. An energy storage system affords the opportunity
Because of the low installed capacity, some RMC stations use only batteries with limited energy storage and lifetime [21]. A complete battery discharge will result in an unavoidable shutdown of the RMC station for the replacement period of the used batteries, inspection, and repair of failures.
