“…The extra energy produced, compared to the autonomous load request, must be stored. This can be achieved in different ways [12][13][14]. However, in the case of standalone applications, storage cost still represents the major economic restraint.…”

This paper deals with the study of a variable speed wind induction generator associated to a flywheel energy storage system. Direct torque control strategy is applied to control the induction generator where both rotor flux and DC bus voltage are controlled through the application of the standard switching table for operations in the 4 quadrants. The flywheel energy storage system is used to improve the quality of the electric power delivered by the wind generator. The proposed system, controlled thanks to Direct Torque Control (DTC) strategy, is validated through simulations. The obtained results are presented and discussed.

“…Examples of using the fuzzy-logicbased control of various processes can be found in such diverse areas as controlling wind power plants [6,11,14] and controlling hydraulic systems of forging machines [17]. Methods of artificial intelligence and fuzzy logic are also applied in processes used in environmental protection [3,4] or composting [29].…”

This paper shows the concept and preliminary test of the composting process control with fuzzy logic. The temperature in the compost heap during the process is greater than 80°C. Because wastes of agricultural origin do not require hygienization, part of the heat can by retrieved, which lowers the temperature in the heap to 55°C (this is also the optimum temperature for the composting process). The heat retrieved from a compost heap can be used in another place. Therefore, a composting system was developed in which the aeration rate and heat removal rate can be adjusted. There are two goals of this system: maximising the amount of the heat retrieved from the heap and minimising the duration of the composting process. In the preliminary experiments freshly mown grass with 50 % cabbage was used as the compost material. The results show that the fuzzy logic control system functions correctly with respect to calculations. During the study, a median 90 MJ of heat was produced by the bioreactor; the thermophilic phase was shortened to 12 days. There was also a reduction in the emission of ammonia.

“…A wind farm with many WTG has a tendency of smoothing output power. Various methods have been utilized to generate smooth wind power, including the use of ultra capacitors [5], superconducting magnetic energy storage (SMES) [6], flywheel energy storage systems (FESS) [7][8][9], storage batteries [10], aqua electrolyze fuel cells [11], and backup generators [12]. Each method has its advantages and disadvantages.…”
