The invention discloses a
microgrid energy management system which comprises an information collection and data preprocessing unit, a
network analysis unit and an energy optimization unit, wherein the information collection and data preprocessing unit performs
data mining preprocessing on information, collected by
SCADA / PMU mixed measurement, by adopting a CIM model and combining historical section management, the
network analysis unit is used for realizing mixed measurement-based
microgrid state
estimation on the basis of
network topology analysis, performing risk analysis and assessment and
sensitivity analysis to realize early warning and warning for failure
threat, and adopting corresponding precautionary measures or performing
emergency control, and the energy optimization unit is used for performing
microgrid energy optimization scheduling by combining forecast information and
system operation analysis according to the information of the microgrid state
estimation. The invention also provides a method which adopts the microgrid
energy management system to perform microgrid
energy management. The functions of the microgrid
energy management system are further perfected, and the
system safety, the power supply reliability and the system control accuracy and effectiveness of a microgrid are improved.
