This paper deals with a new isolated wind-hydro hybrid generation system employing one permanent magnet synchronous generator driven by a variable speed wind turbine and another permanent magnet synchronous generator driven by a constant power hydro turbine feeding three-phase four wire local loads. The proposed system utilizes two back-to-back-connected pulse width modulation controlled insulated-gate-bipolar-transistor-based...
This paper deals with a new Autonomous Wind Energy Conversion System (AWECS) employing parallel operated Permanent Magnet Synchronous Generators (PMSGs) driven by variable speed wind turbines and feeding three-phase four-wire local loads. The proposed system utilizes three Pulse Width Modulated (PWM) Insulated Gate Bipolar Transistors (IGBTs) based voltage source converters (VSCs) with a battery energy...
In this paper, a battery energy storage system (BESS) based voltage and frequency (VF) controller based on isolated three-leg VSC with a zig-zag transformer is proposed for stand alone power generation using a permanent magnet synchronous generator (PMSG). An isolated distributed generation (DG) system is realised using fixed pitch wind turbine. The proposed stand alone wind energy conversion system...
A stand-alone power supply system based on wind energy is presented in this paper. A permanent magnet synchronous generator (PMSG) is connected to the load through a switched mode rectifier and an inverter. Battery is used as an energy storage device and interfaced to the wind energy system through DC-DC converter. Control strategies are presented to regulate the voltage and frequency of the output...
This paper deals with an isolated wind-hydro hybrid generation system employing a Squirrel Cage Induction Generator (SCIG) driven by hydro turbine and a Permanent Magnet Synchronous Generator (PMSG) driven by a variable speed wind turbine feeding three-phase four-wire local loads.

The application of a doubly fed induction generator (DFIG) as a suitable generating scheme in a remote or isolated communities is presented in this paper. Remote area power supply (RAPS) system, a dummy load and its controller with energy storage system (ESS) are identified as the key components. The dummy load is used to absorb the power associated with over generation. The battery storage system...
Nowadays, renewable energy such as wind turbine generator and photovoltaic system are introduced in power system. Output power fluctuations of these generation systems will result in frequency deviations and terminal voltage fluctuations. In order to overcome these problems, battery energy storage system is used for frequency and voltage control. However, it needs large capacity of battery system...
