スマートゲートウェイに基づく分散型電源を含むマイクログリッドのディスパッチ方法

Japanese Patent JP7182808

B2

An intelligent gateway-based dispatching method for a microgrid comprising distributed power sources, relating to the technical field of microgrids, and comprising the following steps: A) install an intelligent gateway on a node where a target grid is connected to distributed power sources; B) calculate an eigenvalue of the next time period, if the eigenvalue is less than a set threshold, wind-solar power plants only output active power during the time period, and proceed to step D); C) determine the active power and reactive power output by wind-solar power plants; D) the intelligent gateway performs in-place power control on the wind-solar power plants or energy storage plants according to the voltage and frequency on the node. The present method is suitable for the dispatch of the microgrid having a high penetration rate of renewable energy, achieves easy installation and expansion, facilitates the access of distributed power sources, reduces additional costs of traditional energy sources in adaption to renewable energy access, improves the reliability and safety of microgrid operations, and improves the overall energy utilization efficiency of microgrids.
