Reactive power compensation technology of hybrid capacitor in terminal low voltage distribution network

In modern power systems, efficient terminal low-voltage distribution networks are vital for stable and quality power supply. Increasing industrial and commercial electricity demand raises the proportion of inductive loads, causing power quality issues like low power factor, high energy loss, and voltage fluctuations. [1] Reactive power compensation technology is key to enhancing power system efficiency and stability. Energy routers, intelligent interfaces, leverage advanced sensing and control strategies to monitor grid status in real-time and dynamically adjust reactive power compensation equipment for optimal power quality. the energy router has been considered the crucial element that builds the net structure between the different electrical components components by connecting and controlling the bidirectional power and data flow. [11] This method boosts response speed, compensation accuracy, and grid adaptability to sudden events. Hybrid reactor reactive power compensation technology combines capacitors and reactors. Reactive power compensation with Capacitor Banks is one of the most successful approaches used in distribution systems, mainly due to their versatility, long-term acceptance in the power industry, and reduced costs. Most allocation methods, [12]Capacitors provide leading reactive power, while reactors absorb lagging reactive power. By precisely calculating and configuring these components, grid reactive power is balanced, improving power factor, reducing energy loss, and stabilizing voltage. Practical applications need to consider load characteristics, grid structure, operating costs, and maintenance. Tunable hybrid reactors may be necessary for loads with significant changes. High intelligence in energy routers is essential to accurately adjust compensation strategies, avoiding over- or under-compensation. Hybrid reactor technology in terminal low-voltage distribution improves power supply quality and operational efficiency, supporting green energy transformation and sustainable development goals. With ongoing technological advancements, this field will unlock more potential and applications in the future.
