Three Phases

The solar flare is discussed in terms of its three phases: energy storage, energy release, and dissipation. Some of the problems associated with theoretical modelling are considered, together with the limitations imposed by current observations. New measurements to be made by the N.A.S.A. Solar Maximum Mission satellite are expected to advance significantly our understanding of the flare mechanism.

In this work, it is presented a methodology for the reconfiguration of smart grids that is applied to a smart grid formed by two microgrids that can be electrically interconnected in contingency situations. Each microgrid is also connected to an Electric Power System (EPS) when operating in the normal state. Moreover, the smart grid includes energy storage devices (batteries) located at strategic points. Serious faults that isolated the microgrids of the EPS and, moreover, considerably reduced the generation capacity of such microgrids are simulated. The proposed methodology is applied to reconfiguration in scenarios involving cooperation between microgrids and/or the use of energy storage devices. Performance indices are also proposed to enable a quantitative analysis for each scenario. It is shown that intelligent cooperation between microgrids and the smart-use storage energy is the best option for reducing the impacts in a contingency scenarios.

In order to improve the energy efficiency of electric vehicle (EV) power battery, and increase the start-up power of EV, a kind of maglev flywheel battery storage energy system is designed on EV, it is active suspension controlled at five degrees of freedom. The system suspension control principle is expounded, and the radial single freedom transfer function of the maglev flywheel is established combining with a digital PID control algorithm. The frequency spectrum characteristic of the transfer function and the flywheel rotor trajectory curve are simulated, and the 30000 r/min rotation experiment of the maglev flywheel battery prototype is realized. The experiment result shows that the maglev flywheel rotor may high speed and steadily spin, and has good energy storage ability. The maglev flywheel battery storage energy system can assist the EV power battery work, improves the battery charge and discharge properties and prolongs the service life of the motive power battery.

To study the flywheel storage energy in enhancing the construction machinery engine speed stability, Dynamic model on engine and engine connecting another flywheel is established. With a group of experiment data, load changing effecting the engine speed is compared when the storage energy flywheel is assembled and not. The results indicate that high frequency engine speed fluctuating is less when the storage energy flywheel is assembled, the drive and economy performance is better, and added energy loss is only for friction.
