Electricity is one of the main inputs used in poultry production. An aviary needs electricity to feed the various motors and electrical devices that compose the lighting systems, exhaustion, heating, food, among others. Aiming to give incentives to producers of broiler chickens, specifically in the state of Paraná, Brazil, in 2007, the Night Poultry Program was implemented, in which the government grants discounts in electricity tariff for poultry farmers at night. In this work it was proposed two energy storage systems through the use of lead-acid batteries and batteries of nickel chloride and sodium to feed the of charge of four brazillian aviaries over one year of poultry housing. For this purpose, it was evalueted the use of a bank of batteries in higher tariff, period comprising the time of 9:30 pm to 6 am of the next day, and charging the battery bank in reduced tariff period. The experiment was conducted using the electricity meters installed in the aviaries, weekly data of each aviary were collected and the active energy values, obtaining the data for six lots corresponding to a year of poultry accommodation. From the total consumption of active energy, it was calculated the average daily electricity consumption (kWh) for the set of aviaries. This value was used as input for the sizing of the battery banks. The two proposed storage systems demonstrate an alternative to energy supply for the rural areas, however the economical analysys indicates inviability, since the initial investment of the banks of batteries is high compared with the costs avoided with electricity by using these systems.

“…Several studies have focused on the optimum sizing of hybrid systems with advanced optimization techniques considering resource variability and load uncertainty [9][10][11][12][13][14][15][16][17]. Dynamic behaviors of hybrid systems have been characterized through simulations and experiments [18][19][20].…”

h i g h l i g h t sThermal swelling shape is different than Li-ion intercalation swelling shape. Nonuniform temperature and gap creation leads to a convex shape at free conditions. Important parameters of thermal mechanics are estimated through experiments. A coupled thermal-structural analysis accurately predicts thermal swelling shape. Nonuniform temperature still plays a critical role at pack conditions. Keywords:Lithium-ion battery Battery swelling shape Thermal expansion The coefficient of thermal expansion The coupled thermal-structural analysis a b s t r a c tThe thermal mechanics of Lithium-ion (Li-ion) batteries is explored with a focus on thermal swelling. Experiments show for the first time that the swelling shape of prismatic battery cells due to temperature variations is significantly different from that due to Li-ion intercalation in unconstrained conditions. In contrast to uniform and orthotropic Li-ion intercalation swelling in a direction perpendicular to electrodes, the nonuniform temperature distribution in the jellyroll and the gaps/voids between electrodes result in distinguishable different swelling shapes. A unique coupled thermal-structural analysis with a simple, but efficient 3-D finite numerical model is proposed to investigate the impact of temperature variations on the thermal behaviors of battery cells. Anisotropic heat conduction and temperature dependency of the coefficient of thermal expansion are taken into account and found to have an impact on temperature distribution and thermal expansion. Experimental validation of the proposed model clearly demonstrates that the coupled thermal-structural analysis with the proposed model can predict accurately the thermal swelling at unconstrained conditions. The solution at pack (constrained) conditions shows that the nonuniform temperature distribution of the jellyroll still plays a critical role for the thermal swelling shape, although the gaps/voids do not occur because of the constraints from spacers in the pack, suggesting that the estimation of core temperature is important. Such an accurate model, able to estimate cell thermal behavior, is beneficial to the design of Li-ion batteries, development of stress or strain sensors, optimum sensor placement, and thermal management of not only single battery cells but also battery packs.

“…In 2012, the study of integrated PV-BESs on a current German feed-in tariff in residential applications is the focus of [33]; Mulder et al who affirm that since 2012, the use of lead batteries up to 5 kWh is convenient even in the absence of subsidies, independent of an increase in the cost of electrical energy. Taking the progressive decrease of the cost of lithium batteries into consideration, the authors state that this type of technology will certainly soon be attractive.…”

The paper presents a review of the recent developments of photovoltaics integrated with battery storage systems (PV-BESs) and related to feed-in tariff policies. The integrated photovoltaic battery systems are separately discussed in the regulatory context of Germany, Italy, Spain, United Kingdom, Australia, and Greece; the attention of this paper is focused on those integrated systems subject to incentivisation policies such as feed-in tariff. Most of the contributions reported in this paper consider already existing incentive schemes; the remaining part of the contributions proposes interesting and novel feed-in tariff schemes. All the contributions provide an important resource for carrying out further research on a new era of incentive policies in order to promote storage technologies and integrated photovoltaic battery systems in smart grids and smart cities. Recent incentive policies adopted in Germany, Italy, Spain, and Australia are also discussed.
