The solid oxide fuel cell (SOFC) is used as secondary source in micro grid application. When the renewable sources are not able meet load requirement, Battery energy back-up system supposed to supply demand. SOFC come into action when state of charge (SOC) battery backup becomes too low. parameters assumed constant during its operation but those operating practically constant. vary widely which...

From the past literature survey, it is witnessed that there is remarkable growth in the Wind power capacity in the recent years. The advancement of converters used in wind power technologies led to maximum extraction of wind energy. In this paper, a comparison of Single Boost converter (SBC) with Interleaved Boost Converter (IBC) used in small-scale wind turbine systems. It utilizes the AC-DC-A...

in recent year's renewable energy sources have become a useful alternative for the power generation. the power of photovoltaic is nonlinear function of its voltage and current. it is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (mpp) in various solar intensity. fuzzy logic controller has advantage in handling non-linear system. maximum power ...

A proportional-integral (PI) controller and a sliding mode controller (SMC) are used to control a fourth-order Boost-Boost (BB) converter in continuous conduction mode with two input switches and two output voltages. Based on the equivalent control method, a closed-loop system is developed. The resultant PI gains have a nonlinear relationship with each other. The appropriate PI gains are obtain...

Currently, most photovoltaic (PV) sources are connected to the grid. This research discusses single-phase on-grid PV inverters. A two-stage inverter which consisted of a boost-type DC-DC converter and inverter, was used. In addition, improved power quality deliver maximum power. The entire generated by be delivered PCC, in PCC also improved. this system, grid only drew or supplied active P&O al...

A new topology of a hybrid distributed generator based on photovoltaic and wind-driven permanent magnet synchronous generator is proposed. In this generator, the sources are together connected to the grid with the help of only a single boost converter followed by an inverter. Thus, compared to earlier schemes, the proposed scheme has fewer power converters. Model of the proposed scheme in d-q a...

A simple step and search control strategy for extracting maximum output power from grid connected Variable Speed Wind Energy Conversion System (VSWECS) is implemented in this work. This system consists of a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) through a gear box, a DC-DC boost converter and a hysteresis current controlled Voltage Source Converte...

The buck converter and bi-directional converter connected with common dc bus, that dc bus connected different loads with constant dc voltage. The hysteresis current controller has implemented in inver...

ment of wireless communication systems in recent years, especially for broadband multiuser communication systems which severely suffer from intersymbol interference (ISI) and multiple access interference (MAI). This article reviews batch processing algorithms for blind equalization using higher-order statistics for mitigation of the ISI induced by single-input, single-output channels as well as...

This paper deals with a control scheme to extract maximum power from the wind energy conversion system (WECS) using Maximum Power Point Tracking Algorithm (MPPT) from a Doubly Fed Induction Generator (DFIG). In order to ensure the continuous supply of power, battery backup is established. The control scheme for standalone system includes the charge controller circuit for battery bank and pitch ...
