This paper proposes a capacity expansion model for multi-temporal energy storage in renewable energy base, which advantages lie in the co-planning of short-term and long-term storage resources. This approach facilitates the annual electricity supply and demand equilibrium at renewable energy bases and reduces the comprehensive generation costs.
Capacity expansion modelling (CEM) approaches need to account for the value of energy storage in energy-system decarbonization. A new Review considers the representation of energy storage in the CEM literature and identifies approaches to overcome the challenges such approaches face when it comes to better informing policy and investment decisions.
