3. Types of storage and recent developments. Storage has played an important role in balancing electricity supply and demand since the beginning of electricity systems. Depending on the characteristics of a specific type of electricity storage, it can be used for different purposes and provides various services.
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, …
Energy storage and demand response add additional flexible resources to the system operator''s toolkit, providing them with more options for balancing the grid. Demand response is the ability to reduce demand for electricity in response to either economic signals or requests from grid operators or utilities. Demand response programs …
