With the rapid development of new energy in recent years, its proportion in the power grid is increasing. The impact of its randomness, intermittence and negative peak regulation characteristics on the power grid is more and more significant. The "duck curve" characteristic of high proportion of new energy is obvious, which brings great pressure to …
Abstract. Thermal energy storage (TES) is increasingly important due to the demand-supply challenge caused by the intermittency of renewable energy and waste heat dissipation to the environment. This paper discusses the fundamentals and novel applications of TES materials and identifies appropriate TES materials for particular …
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 …
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 …
6.4.1 General classification of thermal energy storage system. The thermal energy storage system is categorized under several key parameters such as capacity, power, efficiency, storage period, charge/discharge rate as well as the monetary factor involved. The TES can be categorized into three forms ( Khan, Saidur, & Al-Sulaiman, 2017; Sarbu ...
Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.
New energy storage methods based on electrochemistry can not only participate in peak shaving of the power grid but also provide inertia and emergency power support. It is necessary to analyze the planning problem of energy storage from multiple application scenarios, such as peak shaving and emergency frequency regulation. This …
In this study, with different peak load regulation modes, thermal power units are considered for peak load regulation in power systems. An optimal scheduling …
Conclusions. This study investigate how that aggregation and planned allocation of cooling loads through thermal energy storage (TES) can help reduce power system operation costs by reducing peak usage and flattening out the load profile. A system optimization method is used in order to optimally allocate flexible cooling loads and thus …

Considering the excellent performance of energy storage systems, a heat-coupled storage system with high- and low-pressure bypass is proposed to increase peak regulation capacity. Employing a …
In a concentrating solar power (CSP) system, the sun''s rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. This enables CSP …
Simulation results demonstrate that DDE-PI can not only regulate the load with fast and moderate tracking performance but also improve the stability of the …
Thermal energy storage technologies allow us to temporarily reserve energy produced in the form of heat or cold for use at a different time. Take for example modern solar thermal power plants, which produce all of their energy when the sun is shining during the day. The excess energy produced during peak sunlight is often stored in these ...
