摘要

目的。分析了世界储能系统的现状,确定了储能系统的发展前景,并对各种储能方法进行了比较。研究方法。考虑到乌克兰能源系统截至2021年底的实际指标,电力存储系统的理论论证和比较。结果。表明需要一种理论和实践的方法来实现存储容量,以保持电力系统的平衡。通过对最常见的储电装置的回顾,突出了它们的整体特点。它们都有优点和缺点。然而,在全面的推广方法中,有可能获得最大的预期结果。从“环境友好-成本-相关性-必要性”这条链条来看,最有希望的是氢。科学的新奇。正在考虑将不同特性的各种类型的电池系统组合使用的可能性。实用价值。在工业层面引入电池容量的可能性,以更有效地分散国家能源部门的权力。今天,如果没有必要的基础设施,没有对现有的能量接收和分配站的重新装备,没有大规模的投资,氢就无法发挥作用,因为能量必须从电线转移到天然气,然后再回到电线。也就是说,有一个特定的能量矢量不断处于“过渡”位置。这就是为什么将氢转化为电的每一级的能源效率都会下降的原因。效率,在正常情况下,正常情况下“昨天”的一天在这种情况下会是80%左右。为了输送氢气,必须压缩和冷却氢气。这个过程需要10-15%的能量。为了进一步转化为电能,热能被消耗掉,因此可以以~65-70%的效率获得电能。

Electricity storage systems
Purpose. Analysis of the state of energy storage systems in the world, determination of prospects for their development and comparison of electricity storage methods. Research methodology. Theoretical justification and comparison of electricity storage systems taking into account the real indicators of the energy system of Ukraine as of the end of 2021. The results. Show that there is a need for a theoretical and practical approach to the implementation of storage capacities in order to maintain the balance of the electric power system. As a result of the review of the most common electricity storage devices, their features as a whole were highlighted. All of them have both advantages and disadvantages. However, in a comprehensive approach to their promotion, it is possible to obtain the greatest expected result. The most promising, from the point of view of the chain: environmental friendliness - cost - relevance - necessity, is – hydrogen. Scientific novelty. Is that the possibility of combined use of various types of battery systems with different characteristics is being considered. Practical value. The possibility of introducing battery capacities at the industrial level for more effective decentralization of the state's energy sector. Today, without the necessary infrastructure, re-equipment of existing energy-receiving and distribution stations, large-scale investments, hydrogen cannot become effective, as much as it is capable, because energy must move from the wire to the gas, and then back to the wire. That is, there is a certain vector of energy that is constantly in a "transitional" position. That is why the energy efficiency at each of the levels of converting hydrogen into electricity drops. Efficiency, under normal, normal conditions of "yesterday's" day in this case will be about 80%. To transport hydrogen, it is necessary to compress and cool it. This process takes up to 10-15% of energy. For further transformation into electrical energy, thermal energy is consumed, and as a result, electricity can be obtained with an efficiency of ~65-70%.
