Research on construction of smart AVC in transitional period

Smart AVC is an important component of smart grid. This paper summarized the development situation of AVC in China and foreign countries, proposed the concept, objectives and characteristics of Smart AVC, and pointed out the direction of the current AVC developed to Smart AVC. Also, the paper proposed the following important tasks during the transitional period: adjustment of reactive power compensation layout in grid, increase in dynamic reactive power compensation installation and smart power plants, and construction of smart substation. Besides, the paper explained such as self-adapted, user-friendly interaction and self-healing functions and characteristics, and illustrated we should transform grid benefit growth way and make three indexes (voltage quality, line loss and voltage stability) simultaneously arrive at the best condition. At last, the paper showed the reactive power market is the driving force for construction of Smart AVC.
