The variability of wind power generation requires the allocation of a flexible energy reserve which is capable of compensating for possible imbalances between the load and generation. To reduce the variability of wind power generation and loss of load in generation deficit, we propose operation strategies for coordinating battery energy storage with wind power generation. The effects of the operation strategies on system reliability are evaluated by the developed computation model that represents the main aspects and operation limitations of the batteries. The performance evaluation of the power system is based on the composite reliability indices of loss of load probability(LOLP) and expected energy not supplied(EENS), which is calculated through sequential Monte Carlo simulation. Tests are performed by the developed model with a tutorial system consisting of five busbars and the IEEE RTS system. The results show that the use of large-scale batteries is an alternative to physically guarantee the wind power plants and to act as an operation reserve to reduce the risk of loss of load.

Simulation model of micro-grid including a direct-drive wind power generation, two sets of power-controlled distributed generations（DGs） and a three-phase fault module was investigated in Matlab/simulink. Based on the constructed model, the operating process switched from island mode to grid-connected mode was simulated and the voltage variance signal was detected with Daubechies（Db） wavelet. The simulation results show that the singularity of voltage variance was quickly and accurately detected with db wavelet. The fast and accurate detection of short-circuited fault signal is helpful to improve power quality of micro-grid.

For the characteristics of wind power generation system is multivariable, nonlinear and random, in this paper the neural network PID adaptive control is adopted. The size of pitch angle is adjusted in time to improve the perfomance of power control. The PID parameters are corrected by the gradient descent method, and Radial Basis Functiion （RBF） neural network is used as the system identifier in this method. Sinlation results show that by using neural network adaptive PID controller the generator power control can inhibit effectively the speed and affect the output prover of generator. The dynamic performnce and robustness of the controlled system is good, and the peformance of wind power system is improved.

Background, Motivation and Objective Energy is the material foundation of human existence and economic development. With the rapid development of economy, however, energy shortages, environment pollution and ecologic deterioration has become increasingly serious. Thus the invention and manufacture of more environmentally friendly equipment are of greats importance to researchers from all over the world. wind energy in the ambient can be harvested as a new type of energy since which exists in almost every corner of the natural world. For low-power electronic devices, if its battery is equipped with small charging system getting energy from the surrounding environment, the battery replacement will be greatly reduced. It is one possible solution that the surrounding wind energy converted into electrical energy by piezoelectric materials. Our aim is to design an environmentally friendly, efficient and simple, easily to manufacture, low cost wind energy collection device, which can supply the power for the low-power wireless sensor networks and so on. Statement of Contribution/Methods This work used the PVDF piezoelectric film as an energy conversion material to design an efficient wind energy collection equipment which has simple structure, low cost and high efficiency. This device transforms random wind energy into electrical energy by an effective vibration action of the piezoelectric film. The simulation of the swing state of PVDF in the device by the software ANSYS. The PVDF piezoelectric film in series and parallel are both analyzed to investigate the effect of the wind speed and pressure on output voltage and power. For the sake of comparison, an experiment is conducted to evaluate the effect of the wind speeds on the PVDF piezoelectric film using a fan to simulating the natural wind. Results This paper shows that the force on the piezoelectric film increases with the increase of the wind speed because the greater distortion of the PVDF piezoelectric film creates

＜正＞In this paper, a test-bed built for the experiments of variable-speed constant-frequency （VSCF） wind power generation is described. The test-bed is composed of a doubly fed induction generator （DFIG）, a VVVF inverter driven squirrel motor for wind turbine simulation, dual-DSP-based controllers, as well as a PC-based data-acquisition and control system. In this system, a pair of bidirectional PWM voltage-source converters in a back-to-back configuration is inserted between the rotor windings and the grid lines to control the rotor currents in order to vary the slip power thereby implementing the VSCF operation. Vector-control is used to independently control the flow of active and reactive power between the system and grid line, and to make it easy for the system to implement maximal power point tracking （MPPT） and optimal reactive power splitting in wind power plants.
