Analysis of The Current Research Status of Reactive Power Compensation Technology for Power System Network

In practice, reducing reactive power to enhance system efficiency is a common objective. While this approach is generally beneficial, it can pose challenges in electrical systems that are purely resistive or capacitive. AC power systems involve the supply or consumption of two types of power: real power, which executes convenient effort, and reactive power, which provisions voltage points critical for system reliability. The management of reactive power significantly influences the security of power systems by impacting voltage stability across the network. The demand for power has surged rapidly while our generation resources remain limited. Consequently, transmission lines are becoming heavily loaded, leading to stability issues, voltage drops, and reactive power challenges. This paper explores the necessity of reactive power and various compensation techniques essential for any power system. It focuses particularly on FACTS devices like SSSC, TCR, TCSC, STATCOM, UPFC and DPFC.
