The main objectives of introducing energy storage to a power utility are to improve the system load factor, achieve peak shaving, provide system reserve and effectively minimise the overall cost of energy production. Constraints of various systems must also be satisfied for both charge and discharge storage regimes.
How much storage capacity should a power plant have?
From computations performed, it was suggested that for base load operations, an extremely large storage capacity equivalent to nearly a thousand full load operating hours should be available to a power plant to achieve continuous electricity production using only solar energy (solar fraction equal to 1.0) during an annual operating cycle.
Why is energy storage important?
Flexible, scalable design for efficient energy storage. Energy storage is critical to decarbonizing the power system and reducing greenhouse gas emissions. It's also essential to build resilient, reliable, and affordable electricity grids that can handle the variable nature of renewable energy sources like wind and solar.
