In this paper, the design and implementation of a permanent magnet synchronous generator (PMSG) based wind energy conversion system battery bank storages are connected to utility grid. It has phase locked loop (PLL) control strategy as it provides for single-phase grid inverter with constant dc-link voltage. The is interfaced through diode bridge rectifier (DBR) dc-dc boost converter, single vo...

Wind power plants (WPPs) are required to provide primary frequency regulation services when a high proportion of wind is connected the grid. The reserve turbine generators (WTGs), including rotor kinetic energy and deloading power, determined by its current speed active thus, different levels WTGs will be formed because variable wake effect in WPP. This article proposes an adaptive control stra...

With the increasing penetration level of wind turbine generators (WTGs) integrated into power system, WTGs are enforced to aid network and fulfill low voltage ride through (LVRT) requirements during faults. To enhance LVRT capability permanent magnet synchronous generator (PMSG)-based WTG connected grid, this paper presents a novel coordinated control scheme named overspeed-while-storing for PM...

Objective: The aim of the present study was to evaluate artificial insemination techniques on reproductive performance in Ghezel ewes synchronized with CIDR during breeding season. Methods: All ewes were treated with controlled internal drug release device (CIDR) inserted into the vagina of the ewes for 14 days. All ewes were treated a single intramuscular (IM) dose of PMSG was injected. In thi...

AIM The aim of this study was to evaluate the efficacy of three different treatment protocols for estrus induction and conception rate in postpartum anestrus buffaloes during breeding season under field conditions. MATERIALS AND METHODS The 47 postpartum anestrus buffaloes of the 2nd to 6th parity were divided into three groups. Group 1 (n=16): Buffaloes received cosynch treatment, that is, b...

We previously reported that the intraperitoneal and intrabursal administration of bestatin, an aminopeptidase inhibitor, enhanced follicular growth and ovulation in immature mice. In this study, we examined the effect of bestatin on follicular growth and ovulation under the conditions in which the ovarian response to gonadotropins was suppressed. Immature female mice were exposed to 72-h contin...

Ewes were treated with a medroxyprogesterone acetate (MAP) sponge for 8 d followed, at sponge removal, with 500 IU pregnant mare serum gonadotropin (PMSG) at d 30, 40 or 50 (d 0 = lambing) to induce estrus. Dry and lactating ewes were divided into equal numbers at each postpartum day and bred at estrus. Conception rates and number of accessory sperm were determined by flushing the oviducts 3 d ...

In this paper, we focused on modeling and simulation of a hybrid solar-wind energy system, consisting photovoltaic cell wind turbine driven by Permanent Magnet Synchronous Generator (PMSG). The proposed system gives details the system. PV subsystem, there will be MPPT controller, DC-DC boost converter. subsystem includes PMSG, controller. controllers were designed to extract maximum power regar...
