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 …
In the last few years, several investigations have been carried out in the field of optimal sizing of energy storage systems (ESSs) at both the transmission and distribution levels. Nevertheless, most of these works make important assumptions about key factors affecting ESS profitability such as efficiency and life cycles and especially about the specific costs …
With the rapid development of new energy sources and the increasing proportion of electric vehicles (EVs) connected to the power grid in China, peak load regulation of power systems will face severe challenges. Therefore, in this study, we analyzed the relationship ...
Peak-regulation ancillary service is the most important way to adjust load balance, promote grid-connected of wind power generation, and reduce wind curtailment (Shu et al. 2019). Now with the increasing share of renewable energy sources in the electricity mix, coal-fired power plants participate in peak load regulations frequently …
However, they are promising options for other applications such as peak shaving, time shifting, load levelling, black start, seasonal storage, and network expansion. The appropriate selection of grid-scale ESSs depends on various factors such as system capacity, required performance, ESS cost and reliability, and type of application.
Battery Energy Storage System (BESS) can be utilized to shave the peak load in power systems and thus defer the need to upgrade the power grid. Based on a rolling load forecasting method, along with the peak load reduction requirements in reality, at the planning level, we propose a BESS capacity planning model for peak and load …

Due to the randomness and uncertainty of renewable energy output and the increasing capacity of its access to power system, the deep peak load regulation of power system has been greatly challenged. The application of energy storage unit is a measure to reduce the peak load regulation pressure of thermal power units.
To gain insights into the energy consumption patterns of the cluster of buildings, we utilized EnergyPlus simulation results provided by the CityLearn platform. These results allowed us to obtain load curves for each building over a specific time period. Fig. 2 illustrates the obtained load curves, where the left-hand chart shows the load …
The peak regulation policy in Shanghai, China, requires a minimum response capacity of 1 MW for LA []. The maximum response capacity is 9.5 MW for 10,000 AC loads (see Figure 7). Hence, we set the target response capacity as …
Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.
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.
A 2018 World Energy Council report showed that energy storage capacity doubled between 2017 and 2018, reaching 8 GWh. The cur-rent projection is that there will be 230 GW of energy storage plants installed by 2030 [2–5]. Microgrids are a means of deploying a decentralized and decarbonized grid.
In the optimized power and capacity configuration strategy of a grid-side energy storage system for peak regulation, economic indicators and the peak-regulation effect are two key considerations. In this paper, the peaking effect is added to the …
