“…Short-medium term energy storage elements like batteries, can increase the system security under changes in consumption or production, and also during startups or shutdowns of the long-term storage equipment which has a slower dynamic [98][99][100]. In the same way, batteries will supply energy during energy deficit situations, allowing the reduction of hydrogen utilization, and therefore reduction in fuel cell and electrolyzer degradation by use.…”

“…On the other hand, in case of high SOC, the voltage mode will protect the battery with a slower charge mode in which current will be imposed by battery voltage [50,137]. The use of a reduced depth of discharge will extend the lifetime of the battery [98,101,102,138]. -Hysteresis Band: The use of hysteresis based on the battery SOC will determine the start or stop conditions of fuel cell and electrolyzer.…”

Hybrid systems are presented as a viable, safe and effective solution to minimize the associated problems of the dependence on renewable energies with the environmental resources. In this way different renewable systems such as photovoltaic, wind, hydrogen and so on, can work together to configure hybrid renewable systems. However, to make them work properly in a holistic way by creating synergies among them is not an easy task. Recently hydrogen technology has appeared as a promising technology to hybridize renewable energy systems, since it allows the generation (by electrolyzers) and storage of hydrogen when there is a surplus of energy in the system, and at a later time (e.g. when there are insufficient renewable resources available) using the stored hydrogen to generate electrical energy by fuel cells. The choice of a correct energy management strategy should guarantee an optimum performance of the whole hybrid renewable system; therefore, it is necessary to know the most important criteria in order to define a management strategy that ensures the best solution from a technical and economic point of view. This paper presents a critical review and analysis of different energy management strategies for hybrid renewable systems based on hydrogen backup. In the same way, a review is also presented of the most important technical and economic optimization criteria, as well as problems and solutions studied in the scientific literature.

“…LA batteries are cheaper than other battery technologies but relatively heavier and bulkier in size and take longer time during charging as compared with other types of batteries . They operate in a temperature range between −5°C and 40°C and have rated cell voltage of 2 V . LA batteries have short cycle life (1000 to 2000 cycles) and cannot be discharged deeply.…”

Summary The demand of electric energy is increasing globally, and the fact remains that the major share of this energy is still being produced from the traditional generation technologies. However, the recent trends, for obvious reasons of environmental concerns, are indicating a paradigm shift towards distributed generation (DG) incorporating renewable energy resources (RERs). But there are associated challenges with high penetration of RERs as these resources are unpredictable and stochastic in nature, and as a result, it becomes difficult to provide immediate response to demand variations. This is where energy storage systems (ESSs) come to the rescue, and they not only can compensate the stochastic nature and sudden deficiencies of RERs but can also enhance the grid stability, reliability, and efficiency by providing services in power quality, bridging power, and energy management. This paper provides an extensive review of different ESSs, which have been in use and also the ones that are currently in developing stage, describing their working principles and giving a comparative analysis of important features and technical as well as economic characteristics. The wide range of storage technologies, with each ESS being different in terms of the scale of power, response time, energy/power density, discharge duration, and cost coupled with the complex characteristics matrices, makes it difficult to select a particular ESS for a specific application. The comparative analysis presented in this paper helps in this regard and provides a clear picture of the suitability of ESSs for different power system applications, categorized appropriately. The paper also brings out the associated challenges and suggests the future research directions.

“…On the other hand, the batteries lifetime depends on the depth of discharge (DOD) and operation conditions, so it is necessary to guarantee the use of them under security margins (Sacarisen & Parvereshi, n.d.), (Ng, Moo, Lin, & Hsieh, 2008). Finally, the use of an electrolyzer under very low power operation points or dynamic start/stop conditions, can suffer extra deterioration in electrolyte, and also operate in very low efficiency operation point (Ziogou et al, 2013;Miland & Ulleberg, 2012).…”

This paper presents a new and optimal proposal of energy management strategy for a solar panels/wind turbines/fuel cell/battery/alkaline electrolyzer on grid hybrid power system. These new proposal takes into account technical and economical optimization parameters, improving the system performance, the lifetime of different elements and reducing operation and maintenance cost. The features of the proposed energy management strategy are compared over other strategies found in the scientific literature. Additionally, another key parameter like fuel cell modularity has been considered. That is the effect over the whole system performance of using a single fuel cell with high rate power (PFC) versus a modular configuration built from n stacks with PFC/n rate power each one. Then, joining the new proposed strategy with the optimization parameter regarding the fuel cell modularity, it is possible to get the best solution for this kind of hybrid systems.
