“…However, this will increase the overall system and operating costs. The smoothing methods are classified into two groups; (i) without utilization of energy storage devices and (ii) by utilizing energy storage devices [24,25]. The first group is based on pitch angle control [37] and the kinetic energy of inertia control [38].…”

Abstract:Wind energy is one of the most common types of renewable energy resource. Due to its sustainability and environmental benefits, it is an emerging source for electric power generation. Rapid and random changes of wind speed makes it an irregular and inconsistent power source when connected to the grid, causing different technical problems in protection, power quality and generation dispatch control. Due to these problems, effective intermittent smoothing approaches for wind power output are crucially needed to minimize such problems. This paper reviews various intermittent smoothing approaches used in smoothing the output power fluctuations caused by wind energy. Problems associated with the inclusion of wind energy resources to grid are also briefly reviewed. From this review, it has been found that battery energy storage system is the most suitable and effective smoothing approach, provided that an effective control strategy is available for optimal utilization of battery energy system. This paper further demonstrates different control strategies built for battery energy storage system to obtain the smooth output wind power.

“…It is, however, difficult to store hydrogen and to transport it safely in commercial quantities without using bulky, heavy‐duty equipment, either through compression or cryogenic liquefaction, because of its low boiling point and high flammability. Thus, commercially viable hydrogen storage technologies have become one of the roadblocks to the developing ways to use hydrogen energy on a large‐scale …”

With its low melting point of −17.8 °C and gravimetric density of 5.23 wt %, N‐ethylindole is a promising candidate for use as a liquid organic hydrogen carrier (LOHC). Here, the influences of reaction temperature and hydrogen pressure on the hydrogen capacity of N‐ethylindole in the liquid phase are studied. It is found that fully hydrogenated N‐ethylindole can be achieved at 190 °C within 80 min. The hydrogenation of N‐ethylindole over 5 wt % Ru/Al2O3 is found to follow first‐order kinetics with an apparent activation energy of 62.4 kJ mol−1; its rate constant is subsequently derived. The initial rate and turn‐over frequency (TOF) at 160 °C–190 °C are also calculated. The structures of the intermediates during hydrogenation of N‐ethylindole are discussed based on the results of density functional theory calculations. Finally, the hydrogenation mechanism for N‐ethylindole is established.

“…Researchers found that the implementation of energy storage can reduce total energy generation costs for wind energy penetration levels by up to 30% [12]. The storage technologies used in renewable energy are not only in the form of electrical energy, but also the chemical and thermal energy [13].…”

“…Thermal energy storage (TES) has been proved to be a practical energy dispatcher, because it is cost effective, large scale allowed, long-lived and environmentally friendly [13,14]. Two-tank sensible-heat TES system (storing and releasing thermal energy by heating and cooling storage medium [15]) using Solar Salt (binary mixture of 60% NaNO 3 and 40% KNO 3 ) as a heat transfer fluid (HTF) and a storage medium is the most widespread TES configuration at commercial level due to its high thermal efficiency and strong operability [16,17].…”

Abstract:The development of the wind energy industry is seriously restricted by grid connection issues and wind energy generation rejections introduced by the intermittent nature of wind energy sources. As a solution of these problems, a wind power system integrating with a thermal energy storage (TES) system for district heating (DH) is designed to make best use of the wind power in the present work. The operation and control of the system are described in detail. A one-dimensional system model of the system is developed based on a generic model library using the object-oriented language Modelica for system modeling. Validations of the main components of the TES module are conducted against experimental results and indicate that the models can be used to simulate the operation of the system. The daily performance of the integrated system is analyzed based on a seven-day operation. And the influences of system configurations on the performance of the integrated system are analyzed. The numerical results show that the integrated system can effectively improve the utilization of total wind energy under great wind power rejection.
