Description

Technical field [0001] The invention specifically relates to a smart grid voltage and reactive power adjustment device, belonging to the technical field of smart grid reactive power adjustment. Background technique [0002] In recent years, as one of the national strategic developments of various countries, the smart grid has received continuous attention. The so-called "smart grid" refers to a grid system that can obtain and distribute electricity more intelligently. Smart grids allow the access of various types of power generation and energy storage systems to promote the vigorous development of the electricity market. Through the interaction of supply and demand in the market, smart grids can most effectively manage parameters such as energy, capacity, capacity change rate, and power flow congestion, reduce power flow congestion, and expand the market. In addition, the smart grid optimizes its asset application to make operation more efficient. [0003] The power system is a h...
