In recent years, with the rapid growth of wind power installed capacity, the proportion of wind power into the power grid has also continued to increase. However, the randomness and the volatility of the active power output of wind farms have also brought challenges to the smooth operation of the power grid. This affects the safe and reliable operation of the power grid. Therefore, in order to enhance the ability of wind power to support the stable operation of the power grid, wind farms are required to adjust the active power output according to the grid dispatching requirements, so the...

Coronary artery systems are a kind of complex biological systems. Their chaotic phenomena can lead to serious health problems and illness development. From the perspective of engineering, this book investigates the chaos suppression problem. At first, nonlinear dynamics of coronary artery systems are presented. To suppress the chaotic phenomena, some sliding-mode-based methods are adopted. Since coronary artery systems suffer from uncertainties, the techniques of disturbance observer and extreme learning machine are taken into consideration. The system stability is proven in the sense of...

Mit der Erschöpfung der globalen fossilen Energie, hat die Entwicklung der Stromerzeugung aus erneuerbaren Energien eine wichtige Rolle bei der Linderung der aktuellen Stromnetzspannung gespielt. Aufgrund der größeren Auswirkungen der volatilen und intermittierenden Eigenschaften der erneuerbaren Energien wie Windkraft und Photovoltaik, der Betrieb des Stromnetzes , wie Arbeit, Frequenz, Spannung und so weiter, gibt es viele Schlüsseltechnologien, wie z. B. Lastprognose-Technologie, Spannungs- und Blindleistungsregelungs-Technologie, Wirkleistungs-Dispatching-Technologie, etc. Dieses Buch...

Avec l'épuisement de l'énergie fossile mondiale, le développement de la production d'énergie renouvelable a joué un rôle important dans l'atténuation de la tension actuelle du réseau électrique. Cependant, en raison de l'impact plus important des caractéristiques volatiles et intermittentes des énergies renouvelables telles que l'énergie éolienne et photovoltaïque, le fonctionnement du réseau électrique, comme le travail, la fréquence, la tension, etc., de nombreuses technologies clés sont impliquées, telles que la technologie de prévision de la charge, la technologie de...

The issue of multi-robot formation is one of the most important branches of robot control and as a hot research topic in the collaborative research of multi-agents. The formation control of robots has been used in the complex tasks such as military search, submarine formation, and drone formation. The formation of multiple robots in collaboration with each other can complete a variety of complex tasks, improve work efficiency, reduce energy consumption costs, and increase the probability of task completion. This book takes wheeled mobile robots as the research object and applies three novel...
