The use of BESS to achieve energy balancing can reduce the peak-to-valley load difference and effectively relieve the peak regulation pressure of the grid [10]. Lai et al. [11] proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.

Moreover, a coupled PV-energy storage-charging station (PV-ES-CS) is a key development target for energy in the future that can effectively combine the advantages of photovoltaic, energy storage and electric vehicle charging piles, and make full use of them [].
The capacity of energy storage device is determined by the constraints of peak load shifting. To further investigate two control strategies, the evaluation indexes, including peak clipping rate, peak-valley rate, and standard deviation of load change are designed for assessing effects of different charging/discharging control strategies on the operation of …
This paper studies a deployment model of EV charging piles and how it affects the diffusion of EVs. The interactions between EVCPs, EVs, and public attention (PA) are investigated based on monthly panel data from 20 provinces in China with the most EVCPs from February 2016 to April 2018.
1. Introduction With a low-carbon background, a significant increase in the proportion of renewable energy (RE) increases the uncertainty of power systems [1, 2], and the gradual retirement of thermal power units exacerbates the lack of flexible resources [3], leading to a sharp increase in the pressure on the system peak and frequency regulation …
The peak distribution of the charging load in the variable power charging strategy is around 16:00, which is similar to the peak time of the basic load. The total load curve reaches two small peaks at 10:00 and 16:00, and the load peak-to-valley difference is small and smooth.

In many chiller plants, high coefficient of performance (COP) is only achieved at a few favorable part load ratios (PLRs), while the COP is low at many other non-favorable PLRs. To address this issue, this study proposes a generic load regulation strategy that aims to maintain chiller plants operating at high COP, particularly under non …
To reduce the peak-to-valley ratio of the night load, the discharge rate of energy storage at t h ∈ [8, 12], which is far lower than that of discharge rate at the same peak price of t h ∈ [17, 21], is given priority by the scheduling system during the …
