As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
What is the energy system dispatch optimization model?
In this research, an energy system dispatch optimization model is employed. It includes an iterative approach for generating grid constraints, which is decoupled from the linear unit commitment problem. The dispatch of all energy carriers in the system is optimized while considering the physical electrical grid limits.
What are the different types of energy storage technologies?
Classified by the form of energy stored in the system, major EES technologies include mechanical energy storage, electrochemical/electrical storage, and the storage based on alternative low-carbon fuels.
Do different sources of dispatchability contribute to a power system's decarbonization?
This study systematically compares the roles that different sources of dispatchability could play in a power system's decarbonization and the evolution of its topology over the period from 2020 to 2060, with China as a case study. Results show that adding these resources to a system's operation yields multiple benefits for decarbonization.
Can electric power systems be dispatchable?
Some of these resources could provide the electric power system with much-needed dispatchability, but the value of each will evolve over time and space, as will the impact of their deployment on economic costs and carbon emissions.
