This paper presents the variable parameter resized zero attracting least mean fourth (VP-RZA-LMF) control algorithm for grid-tied photovoltaic (PV) system. The proposed control algorithm is superior over the conventional control algorithms in terms of swift response and handling the irregular nature of solar irradiations. The DC bus voltage control is incorporated in voltage source converter (VSC) control. The boost converter utilizes the maximum power point tracking (MPPT) algorithm for producing its gating sequence to keep PV array voltage constant.Keywords -Photovoltaic (PV), grid-tied, variable parameter resized zero attracting least mean square (VP-RZA-LMS)

“…However, as the power generated by the PV resources is continually changing in an unpredictable manner, the integration of energy storage systems became indispensable for an interruptible service [10]. In addition, the PV systems with energy storage can provide ancillary services to the grid such as, voltage and frequency support [11]. In [12], MMC for PV systems with energy storage has been proposed, where each submodule has a PV panel in parallel and the batteries are installed on the dc side of the MMC.…”

This paper presents a multilevel topology of photovoltaic (PV) system with integrated energy storage system (ESS). In this proposed topology, half of the cells are connected to PV panels, the rest are connected to batteries. The sum of the cells are connected in series to form a dc-link, which is then connected to an H-bridge to convert the dc voltage to an ac one. The advantage of the proposed topology compared to the modular multilevel converter (MMC) as well as compared to the cascaded H-bridge converter is that less active switches are needed here. More switches are saved as the level of the output voltage increases, which results to a cheaper and less sizable converter. A local maximum power point tracking (MPPT) algorithm is proposed for this converter, which requires the voltage and current of each sub-module. Hence, there are no losses related to partial shading effect here. The excess of power in case of high irradiation levels is stored in the batteries, and is recovered when needed. A detailed simulation program has been built to test the effectiveness of the proposed converter; the obtained results are shown in the paper.

“…The biggest expense in EVs is the cost of the batteries, thus a battery management system is required to achieve the best performance. Lately, lithium batteries are broadly used in many applications and they are the most common energy storage devices as substitution of standard fuel [2]. They are broadly used for several purposes such as uninterruptible power supply (UPS), electric bike, electric scooter, and hybrid electric vehicles (HEV) [3].…”

In this paper, a c ´ uk converter balancing method by using a coupled inductor for lithium based batteries is investigated. The proposed circuit is an active balancing circuit that will equalize eight battery cells in a series. In electrical vehicles (EV), a battery management system (BMS) is a vital task to achieve the best performance of the batteries and longer lifetime. The problem of voltage difference in a battery pack is an important issue to be improved. To overcome the voltage differences in battery string, an equalizing method is mandatory. The conventional c ´ uk converter requires 2(n − 1) switches to balance n cells, while the proposed circuit requires only n switches for n cells in series. In addition, the proposed developed topology uses coupled inductors instead of un-coupled inductors, unlike the traditional c ´ uk converter balancing method. Since the c ´ uk balancing transfers the energy among two adjacent cells, it requires a proportionately long equalization time particularly for long string battery packs, but the coupled inductor c ´ uk converter type overcomes this problem. The switches are N-channel metal-oxide field-effect transistor (MOSFET) to achieve lower drain-source on-resistance, R D S ( o n ) , and less voltage drop as compared to the P-channels. The switches are triggered by complementary signals. The coupled inductor is made in such a way to hold the same magnetizing inductance. It can be done by using five wires in one hand. The circuit contains five inductors, one magnetic core, with five winding for eight cells, and one capacitor for two cells. Therefore, the overall circuitry and complexity of the circuit are reduced, resulting in a more cost-effective and easy to implement circuit. The system also does not demand complicated control for battery equalizing. The experimental circuit was implemented and simulation results were obtained to confirm the validity of the proposed system.
