“…The move toward mobile power sources has placed ever more severe requirements on batteries, and necessitates every possible performance improvement that can be made. One strategy that is taken as axiomatic is placing a super capacitor (or bank of super capacitors) in parallel with the battery [24]. Despite yet fairly high price, they have many advantages such as very high rate of charge/discharge [25,26].…”

Sustainable economic development requires the use of renewable energy sources in a rational and thoughtful way. In Polish conditions the use of several types of renewable energy sources on a single setup is a new issue. In particular, hybrid devices in conjunction with intelligent energy systems, such as lighting systems are generally not used. Therefore, the Polish energy production still relies on the burning of coal. Despite their advantages, renewable energy sources are characterized by seasonality and considerable instability. Access to renewable energy varies daily and seasonally, hence activities promoting the use of autonomous, hybrid power systems must be intensified. The presented research aims at the development of the Autonomous Power Supply (APS) system based on the so-called energy mix. Such a system works in an isolated arrangement and serves to reliably supply electricity from renewable sources for small residential or public utility devices in an urban area. Systems with up to 3 kW power consist of modules, whose modular design allows the combination of various power configurations and types of renewable energy used. The basic system consists of a primary power source, additional power source, emergency power source, energy storage device, weather station and controller. The energy mix depends on the geographical location of the system. The emergency source can be implemented as an on-grid connector or fuel power generator with the participation of 100% until the primary or accessory power source failure is removed. The energy storage system consists of batteries or supercapacitors. The proposed system can be combined to create a local network that automatically responds to energy shortages in various network nodes by adjusting the supply of electricity within the network depending on its needs. For Poland realistic solutions in this article are the new and modern answer to these requirements.

“…These methods are based on the use of long‐term data for wind speed. Others researchers have developed several methods to extract the optimal sizing of renewable systems associated to different storage devices. In this context, the present study scrutinizes the optimal design of a PV system with hydraulic storage ensuring the continuous supply of an isolated typical load demand.…”

The deficit of electricity and high conventional electricity costs still among the major drawbacks for supply remote areas. Electrifying these zones with photovoltaic (PV) systems associated to a hydraulic storage is a promising alternative. The main objective of this study is to optimally size this system generation interacting with irradiations and load cycles, especially for a standalone application. The first part of this article outlines the PV‐hydraulic generation system architecture and modeling. The optimal sizing of the system components satisfying two criteria by means of evolutionary algorithms is described in the second part of this article. The results are finally discussed from the point of view of the relevance of the system sizing and in terms of criteria satisfaction by analyzing two particular optimal configurations. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13095, 2019

“…The hybrid zinc-air achieved double the number of high-power pulses compared to the battery alone. Penella et al [12] observed a 33% improvement in runtime with a primary, silver oxide-zinc battery when hybridized with an EDLC and more recently, Cain et al [13] noted a 46% increase in retrievable energy from a primary Li/MnO 2 battery. A larger number of studies have also focused on hybridizing secondary (rechargeable) batteries with EDLCs.…”

“…A larger number of studies have also focused on hybridizing secondary (rechargeable) batteries with EDLCs. For example, Cain et al observed a 40% increase in capacity with a lithium ion rechargeable battery in the above study [13]. Others have also investigated hybridization of lithium ion batteries with EDLCs as a method to increase cycle life and improve operating temperature performance, in addition to extending battery run time [14][15][16][17][18][19].…”

Although Li/CF x and Li/CF x MnO 2 have two of the highest energy densitiesof all commercial lithium primary batteries known to date, they are typically current-limited and therefore are not used in highpower applications. In this work, a Li/CF x MnO 2 battery (BA-5790)was hybridized with a 1,000 F lithium ion capacitor to allow its use for portable electronic devices requiring 100 W one-minute pulses. An intelligent, power-management board was developed for managing the energy flow between the components. The hybrid architecture was shown to maintain the battery current to a level that minimized energy loss and thermal stress. The performance of the Li/CF x MnO 2 hybrid was compared to the standard Li/SO 2 battery (BA-5590). The hybrid was shown to deliver the same number of 100 W pulse cycles as two BA-5590 batteries, resulting in a weight savings of 30% and a volumetric reduction of 20%. For devices requiring 8 hours of operational time or less, a 5-cell Li/CF x MnO 2 hybrid was found to be a lighter (55%) and smaller (45%) power source than the existing two BA-5590 battery option, and a lighter (42%) and smaller(27%) option than1½BA-5790batteriesalone. At higher power requirements (>100 W), further weight and size improvements can be expected.
