Yeltsin, Ekaterinburg, Russian Federation, 2 RTSoft-SG, Ekaterinburg, Russian Federation На сегодняшний день Li-Ion накопители электроэнергии представляются все более интересными с точки зрения применения их в электроэнергетике. Появляется новый спектр задач, которые могут быть решены с использованием данного типа устройств, а именно: сокращение затрат на электропотребление, снижение максимумов нагрузок в пиковые часы для выполнения требований к пропускной способности сети, применение в системах возобновляемой генерации. При этом пренебрежение сравнительно быстрым и необратимым старением таких систем приводит к чрезмерно оптимистичным экономическим и техническим оценкам их внедрения, что обуславливает необходимость учета старения систем накопления. В данной статье предложена методика квазидинамического моделирования деградации Li-Ion накопителей, которая позволяет в отличие от прочих на стадии предварительного анализа оценивать степень старения систем с неравномерным графиком заряда и разряда, и приведены результаты ее апробации. Li-Ion energy storage systems are currently becoming more and more interesting in terms of their application in power systems engineering. There appeared a new range of tasks that can be solved using such devices appears, i.e. the electrical energy consumption losses reduction, peak loads reduction to meet the network transmission capacity requirements, application in renewable generation systems. However, the neglection of relatively fast and irreversible aging leads to excessively optimistic economic and technical assessments of their implementation, which necessitates to make allowance for their degradation. The article provides the quasi-dynamic Li-Ion storage systems degradation simulation methodology which allows, unlike others, evaluating the aging degree for systems with uneven charge and discharge graph at the stage of preliminary analysis. The results of the methodology testing are also given.
