“…Therefore, the objectives of the target problem are 3-fold: first, to minimize the load curtailment to sustain the system reliability; second, to minimize the unit operation cost to make the system operation economic; and third, to minimize the wind power curtailment to make the operation more environment-friendly. These objectives are all involved in the form of the objective as (32), using the corresponding constraints shown in (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31), min…”

Summary To support a long‐term sustainable electric future, there is ongoing development of electric vehicles, and thus, a serious problem is rising regarding recycling and the echelon application of batteries retired from electric vehicles. Herein, we propose to reuse such retired vehicle batteries as large‐scale storage, based on which the operational reliability and the economy of composite generation and transmission systems are analyzed. In details, Gaussian functions were fitted according to data obtained using a holistic aging model. The proposed aging method simulated the capacity degradation of the retired batteries, with a low state of health, under various operating conditions. A universal generating function was adopted for probabilistic modeling of the capacity for battery modules consisting of hundreds of cells. The feasibility and effectiveness of using retired batteries in composite power systems were verified. The test results show that a significant investment can be saved, and system reliability improved, compared with systems without retired batteries. Finally, a method for scheduling the second retirement of retired batteries was established from the perspective of asset management.

“…Dealing more generally with intermittent sources (mostly wind power and photovoltaics), one of the solutions being proposed to improve the performance of renewable sources is indeed to integrate energy storage devices, such as pumped storage hydro plants, hydrogen storage, flywheels, electrochemical batteries, superconducting magnetic energy storage, into the power system. Recent works have thus analyzed the impacts of energy storage devices on power system operation [56,57,58,59]. These papers show that energy storage systems can secure reliability of supply and reduce the instability phenomena.…”

International audienceThe reliability of power supply, defined as the ability to recover a steady-state condition after a sudden disturbance, is crucial for operating power systems. It is usually ensured by controlling voltage and frequency deviations and involves events occurring from a few milliseconds to a few hours. However, reliability requirements are largely ignored when dealing with long-term issues. To reconcile such contrasting timescales, it seems logical to rely on energy considerations based on thermodynamics. Two reliability indicators, assessing the magnetic and kinetic energy reserves of a power system, are derived from this approach. They enable to quantify the reliability of a given production mix and make it possible to choose between increasing shares of intermittent sources and maintaining an expected level of reliability. Since the indicators tackle reliability issues without focusing on a specific timescale, they are effective for both discussing the long-term evolution of reliability and improving the real-time management of a power system
