Novel technologies for optimization of hydroelectric power plants with hydrogen energy storage system☆

An analytical equation for limiting the minimum reactive power of a salient-pole generator according to the condition of ensuring static stability for a given safety factor, current active power and voltage is obtained. Overall, group reactive power controllers have proven to be a highly effective solution for controlling reactive power in power systems. They offer several advantages over traditional individual controllers, including increased system stability, reduced losses, and reduced costs. When designing and deploying these controllers, it is important to consider factors such as system topology, load characteristics, and more. Overall, group reactive power controllers represent a promising technology for improving the efficiency and reliability of power systems, and further research and development in this area is needed.
