Using vehicle-to-grid (V2G) technology to balance power load fluctuations is gaining attention from governments and commercial enterprises. We address a valuable research gap from a new perspective by examining whether electrochemical energy storage can completely replace V2G technology in terms of balancing grid load fluctuations.
The optimal operation strategy depends on several factors such as the shape of the load curve, the initial SOC of energy storage, the time-of-use electricity price and the conversion method of energy storage life in objective function.
The duck curve is the name given to the shape of the net load curve in a market with a significant penetration of solar energy.The net load curve is the demand curve less all renewable generation.This curve is important because it demonstrates the amount of load remaining to be served by non-renewable generation after loads have been served with all

In general, this makes the ELCC of energy storage much higher than that of renewables since you can choose to dispatch energy storage during the times when the grid is most likely to experience electricity shortfalls. However, energy storage is still limited by its duration. For example, if the grid faces six consecutive hours when load is very
The smoothing of the net load curve enables energy storage systems to more effectively respond to the fluctuations in power generation from new energy. As a result, the demand for energy storage within the system decreases correspondingly, reducing the configuration costs of the energy storage system. Additionally, with the

Power systems with high penetrations of solar generation need to replace solar output when it falls rapidly in the late afternoon—the duck curve problem. Storage is a carbon-free solution to this problem.

IAMs mostly implement load duration curves (LDCs) to capture short-term dynamics . LDCs represent load demand sorted from the highest load to the lowest load. It enables analyzing the dispatch order of energy sources, and they allow, for instance, identifying the fraction of time with a high or low electricity demand.
The fundamental function of energy storage is to absorb available power during times of low or negative residual load and use that to reduce peak residual load. In terms of the rLDC curve, the ‘right end’ would be lifted up while the ‘left end’ of the curve would be lowered.
The energy storage life is also determined by the actual operation strategy of energy storage; and in order to determine the operation strategy of energy storage, the configuration capacity of photovoltaic and energy storage must be given first.
Regional hourly load curves are highly sensitive to the vehicle's charging patterns. The rapidly increasing electricity demand and the expected increase in the contribution of variable renewable energy sources raise the need for looking at the characteristics of long-term demand variations.
For all regions in Fig. 9, the service and residential sectors' load curves contribute to a larger difference between peak and base-load due to their hourly and monthly patterns (non-stacked sectoral LDCs are shown at the end of the supplementary section).
