The invention discloses a technical system for good interaction between electric energy conversion equipment and the intelligent power distribution network, relates to the fields of power generation,power transmission, power transformation, power distribution and power utilization, considers goals of safety, high quality and intelligence, from three sides of a power supply side, a power grid sideand a load side, respectively concludes specific technologies corresponding to the three targets, comprehensively forms three key technology subsystems of flexible and interactive new energy friendly access, friendly support of high-reliability power supply of the power distribution network and friendly power utilization oriented to high power quality, can break through core problems of friendlyinteraction key technology research and core equipment development of the electric energy conversion equipment and the intelligent power distribution network and has very important significance for promoting the technical progress of the intelligent power distribution network. The system is advantaged in that a series of problems of low flexibility and interactivity, insufficient power distribution network power supply reliability, poor user electric energy quality and the like during new energy access are solved, so various electric energy conversion devices with friendly interaction capability are guided and developed, and development of the intelligent power distribution network is promoted.
Description
technical field [0001] The invention relates to the fields of power generation, power transmission, power transformation, power distribution and power consumption, and in particular to a technical system for friendly interaction between power conversion equipment and an intelligent distribution network. Background technique [0002] In the smart distribution network, in order to use electric energy more flexibly, power sources, power grids and users continuously perform various transformations of electric energy according to needs. According to statistics, more than 70% of electric energy in the world is used after transformation. Therefore, there are a large number of power conversion equipment in the "source-network-load" levels of the smart distribution network, such as new energy power generation equipment, energy storage equipment, transformers, rectifier equipment, inverter equipment, electric vehicle charging piles, etc. By performing various transformations on the am...
