Does it reasonable to include grid-side energy storage costs in
We first develop a comprehensive benefit evaluation framework based on economic externality theory considering system stability, renewable energy integration, end-user, and
Tech-economic performance of fixed and mobile energy storage system is compared. The proposed method can improve system economics and renewable shares. With the large-scale integration of renewable energy and changes in load characteristics, the power system is facing challenges of volatility and instability.
Abstract: High penetration of renewable energy resources in the power system results in various new challenges for power system operators. One of the promising solutions to sustain the quality and reliability of the power system is the integration of energy storage systems (ESSs).
Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
Therefore, enhancing the safe and stable operation capability of the power system is an urgent problem that needs to be solved. Mobile energy storage can improve system flexibility, stability, and regional connectivity, and has the potential to serve as a supplement or even substitute for fixed energy storage in the future.
We first develop a comprehensive benefit evaluation framework based on economic externality theory considering system stability, renewable energy integration, end-user, and
