【Abstract】 The equipment capacity of wind farms has expanded dramatically as the scale of wind farm construction in China has increased, and the impact on the power grid has become increasingly serious. SVG dynamic reactive power compensation device plays an important role in meeting reactive power, harmonic control, improving power factor and power quality, reducing loss, adjusting voltage and so on.

At present, solar photovoltaic power generation has matured, and the cost has dropped rapidly. In the foreseeable future, the technology and economy of solar photovoltaic power generation will reach a level comparable to that of conventional energy, which will promote the development of energy transformation and transformation. At the same time, with the deep integration of Internet, cloud computing, big data, artificial intelligence and other modern information technologies with the photovoltaic industry, photovoltaic power stations will develop rapidly in the direction of digitalization, intelligence and informatization, and smart photovoltaic power stations will become the mainstream.
