This paper proposes a fuzzy control strategy to reduce the wind power fluctuations and improve the system reliability. The control strategy aims at controlling charging and discharging energy storage process based on wind power and load changes. What's more, the original strategy is optimized by intervening in battery charging and discharging to manage State of Charge (SOC) of battery. The strategy...
The minimum Steiner tree theory is the basis theory of global shortest path. It is one of the classic NP-hard problems in nonlinear combinatorial optimization. A visualization experiment approach has been used to find Steiner points and the system shortest path named Steiner minimum tree. However, the obstacles must be taken into consideration in some problems. An obstacle-avoiding Steiner minimal...
Wind energy has attracted persistent attention all over the world as a renewable energy, so it is very important to research the permanent magnet generator which is an important part of wind energy conversion system. A simplified computational method for generator design is proposed in this paper, and an experimental device is made to check out the usability of the proposed method. The dynamic performance...
Three-hastate vertical axis wind wheel, a novel type rotor with high efficiency, can be able to actualize wind energy conversion by the lumen twice driven principle, based on the theoretical analysis of the rotor's geometric structure in this research. The computational fluid dynamic analyses, which detect the aerodynamic characteristic of the rotor further, are also described by using the multiple...
