“…If the BESS fail in response time and operational control, large-scale technical and economic losses result for both consumers and utilities. Thus, the control of BESS is the most critical task in grid-scale applications [108,[144][145][146][147][148].…”

Population growth has brought an increase in energy demand and cost that has a meaningful impact on personal and government expenses. In this respect, governments attach importance to investments in renewable energy resources (RER), which are a sustainable and clean energy source. However, the unpredictable characteristics of RER are a major problem for these clean sources and RER need auxiliary assets. Battery energy storage systems (BESS) are one of the promising solutions for these issues. Due to the high investment cost of BESS, governments act cautiously about accepting and implementing BESS in their power network. Recently, with the improvement of technology, the cost of BESS has been reduced, and therefore battery technologies have begun to be applied to conventional systems. In this study, first, we will review and discuss the current globally state-of-the-art BESS and their applications. Later, attention will be turned to a country-specific study for Turkey.

“…Efficiency losses in containerised utility-scale storage systems have been studied in detail by Schimpe et al [28][29][30], and a first demonstration, applied to the arbitrage operation, was given by the authors in a recent contribution [14]. While the work in [14] provided a framework for the techno-economic assessment of marginal cost, in this contribution we extend the existing literature by linking the cost functions of battery ageing and storage system efficiency losses with a state-of-the-art MILP framework.…”

To achieve maximum profit by dispatching a battery storage system in an arbitrage operation, multiple factors must be considered. While revenue from the application is determined by the time variability of the electricity cost, the profit will be lowered by costs resulting from energy efficiency losses, as well as by battery degradation. In this paper, an optimal dispatch strategy is proposed for storage systems trading on energy arbitrage markets. The dispatch is based on a computationally-efficient implementation of a mixed-integer linear programming method, with a cost function that includes variable-energy conversion losses and a cycle-induced battery capacity fade. The parametrisation of these non-linear functions is backed by in-house laboratory tests. A detailed analysis of the proposed methods is given through case studies of different cost-inclusion scenarios, as well as battery investment-cost scenarios. An evaluation with a sample intraday market data set, collected throughout 2017 in Germany, offers a potential monthly revenue of up to 8762 EUR/MWh cap installed capacity, without accounting for the costs attributed to energy losses and battery degradation. While this is slightly above the revenue attainable in a reference application—namely, primary frequency regulation for the same sample month (7716 EUR/MWh cap installed capacity)—the situation changes if costs are considered: The optimisation reveals that losses in battery ageing and efficiency reduce the attainable profit by up to 36% for the most profitable arbitrage use case considered herein. The findings underline the significance of considering both ageing and efficiency in battery system dispatch optimisation.

“…Patsios et al [16] also confirm that the conversion losses in the battery system and power electronics) are significant and warrant a closer look. Not only does the the choice of size, layout and operating strategy of sub-components play an important role in application in determining the overall round-trip efficiency of the system, but also the service being rendered by a BESS [17]. This paper highlights the relation between the conversion losses and aspects such as the application scenario and system configuration.…”

“…Several power electronics topologies are used to interface the battery system to the grid. The most common among these, depending on whether there is a DC/DC voltage conversion stage between the batteries and the AC/DC conversion, are termed as single-stage and the two-stage topologies [17], [44]. Load distribution strategies also play an important role in the final choice of the power electronics components used and their interconnection.…”

“…Schimpe et al [17] have evaluated the relative losses arising due to the operation of the grid coupling components namely the DC/DC bidirectional converter, AC/DC bidirectional converter and the transformer. Two-stage and single stage topologies are also evaluated, with the incremental topology investigated in connection to a prototype system.…”

Energy storage is an important flexibility measure to stabilize and secure the electrical energy supply system. Lithium-ion battery energy systems (BESS) are, owing to their characteristics, uniquely poised to support and augment the functioning of the energy supply system. It is crucial to identify and analyze the factors which play a role in their efficient and effective operation. This paper identifies and analyses three such major factors-application scenarios, power electronics with power distribution strategies, and battery parameters which influence the efficiency of a BESS. The applications analyzed are primary control reserve and peak shaving. Two Power electronics topologies and their load distribution strategies are presented, with their influence on the conversion efficiency being evaluated subsequently. Two commercial lithium-ion technologies-a Lithium Iron Phosphate cathode/Graphite anode cell and a Lithium Nickel Manganese Cobalt Oxide cathode/Graphite anode cell are also simulated for two states of health (SOH). The aged cells are considered to possess a capacity equal to 80% of original nominal capacity and a cell resistance twice that of the new cells. It is found that the system conversion efficiency can be greatly improved in applications with low active chargebased and high temporal utilization ratios by deploying a suitable power electronics topology and load distribution strategy. For applications with high active charge-based and low temporal utilization ratios, the battery resistance and the serial-parallel combination play an important role.
