Evaluation of the limiting conditions for operation of a large electrochemical energy storage system

Abstract

In the last decade, a considerable role has been given to the development of renewable energy sources (Gielen et al., 2019) [1]. However, the unsteadiness of the wind load and insolation is a significant constraint for the transition to non-conventional renewable energy sources (NCRES) - wind turbines and solar panels (Barra et al., 2021) [2]. The use of energy storage systems (ESS) is a necessary factor in the energy transition (Ademulegun et al., 2021) [7]. However, the electrical energy transfer from typical electrochemical energy storage devices to the consumer is accompanied with the dissipation of part of this energy as heat (Henke et al., 2020) [26]. For this reason, it is advisable to assess the overheating of such storage devices, which may lead to a significant decrease in capacitive and resource characteristics (Collath et al., 2022) [43], and in some cases even to ignition and explosions (Murarka et al., 2022) [44]. The article defines the limiting conditions for the operation of electrochemical energy storage devices in a typical autonomous local energy system.
