“…Since the forecasting of wind speed and the time when wind blows is too difficult due to the fact that wind speed is an uncertain parameter, wind power generation would be Storage System (ESS) [93][94][95][96][97][98][99][100][101]. The most common ESS is battery.…”

Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases (GHGs) and also social issues like dramatic increase in global population and increasing energy demand are the main causes of global concerns about energy resource management. In this regard, Renewable Energy Sources (RESs) are the suitable substitution to replace the conventional generating units that emit GHGs due to the use of fossil fuels. Among all RESs, wind energy seems to be promising for generating emission-free electrical energy. However, it is naturally unpredictable due to its intermittency which leads to s ome technical problems such as generation imbalance as well as optimal reserve allocation. This paper investigates the solutions to compensate wind intermittency through introducing various technolo gies such as Pumped-Hydro Storage (PH S) units, Plug-in Hybrid Electric Vehicles (PHEVs), solar energy and other electric storages like batteries. Abstract-Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases

“…For this system, load is a battery which can be considered as energy sink with almost fixed voltage while it is able to absorb power at any level until the charging current is in range. Since, voltage is almost constant and the current would vary, the battery can be considered as a variable-resistance load [95,96].…”

“…The value of capacitance is a function of the switching frequency and the lead inductance between the transformer secondaries and the individual battery modules. The minimum capacitance needed is given by (5) where is the switching frequency and is the lead inductance. At 100 kHz, and assuming a minimum of 1.0 H of lead inductance, a minimum of 2.5-F capacitor is needed.…”

“…A battery system without a balancing technique can lead its cells to be overcharged, undercharged, or even overdischarged, and it takes special importance in Li-ion cells [7]- [9]. The reasons of this imbalance may be of two categories [10]: internal sources (manufacturing variance in physical volume, internal impedance and self-discharge rate) and external sources such as thermal difference across the pack.…”

-In electric vehicle applications, it is necessary to use series strings of batteries since the required voltage is higher than the one that can be obtained from a single battery. Due to several factors, imbalance of batteries in these battery systems is usual and an important factor that has to be taken into account. Many balancing methods have been developed with a lot of different advantages, but all of them also have a lot of disadvantages such as complexity and/or high cost, which are the common problems that can be found in most of these equalization methods. In the present work, a low cost and very simple equalization method is proposed, in which a novel control is applied to a shunting transistor topology. It allows the transistors to regulate the amount of current that goes through each battery cell in the string depending on their State of Charge (SOC), during the charging process. This control ensures that the least charged cells to be charged faster, and the most charged ones to be charged more slowly. Design criteria are discussed and simulation results are carried out in a generic battery low power application which proves the control method. Fast equalization with a low complexity and cost is obtained.
