Techno-economic sizing of a battery energy storage coupled to a wind farm: an Italian case study

Multi-criteria investigation of a pumped thermal electricity storage (PTES) system with thermal integration and sensible heat storage

“…Such figure should not be decided a priori, as it should be calculated by considering thermal energy and electric energy availability, and electric energy prices. Given these assumptions, the storage charge/discharge profile is usually optimized to maximize some objective function, which often is the economic revenue (for a similar analysis in the case of battery storage, see [26,27]). Such analysis is out of the scope of the present study, so an arbitrary numeric value equal to 4 h is assumed for τhp.…”

“…Such analysis is out of the scope of the present study, so an arbitrary numeric value equal to 4 h is assumed for τhp. Despite being arbitrary, this value is realistic in the electric storage practice [26,28], as it is essentially related to the shape of the electric energy price daily trend. ORC condensation heat load is assumed to be rejected into environment by means of an air condenser.…”

Feasibility analysis of a hybrid auxiliary power unit for pleasure boats

“…Battery damaging accumulation is modelled with a cycle-life curve approach, in which the battery capacity loss is calculated from the number of charge/discharge cycles and depth [23]. The cycle-life curve parameters are taken from the literature, and the cycle number and depth are determined with a Rainflow Counting algorithm [23][24]. Inverters lifetime, in accordance with the standard assumptions, is assumed to be ten years.…”

Defining and Evaluating Use Cases for Battery Energy Storage Investments: Case Study in Croatia

“…The results show a clear benefit of adding storage, both in terms of economics and reduction of wind curtailment. Another approach, in which a BESS is coordinated with wind power plants, is presented in [18] for Italian region of Sicily. The methodology aims to maximize revenue of the wind farm owners.…”

“…Similar to paper [18], one of the cases in this paper (Section 2.1) presents an installation of a BESS near to an existing power plant that could be replaced with a PV power plant in the future. The paper approach in [21] is similar to our cases in Sections 2.2 and 2.3 with the addition that we contribute with: (i) Section 2.2 targets to ensure N-1 security criterion by installing a BESS, and (ii) Section 2.3 aims at increasing power evacuation from the observed geographical area during the high production of power plans and an outage of a power line.…”
