The invention discloses a
microgrid energy management system capable of realizing
load management. The
energy management system comprises a man-
machine interaction module, a prediction module, a
system analysis module, a dispatching and control module, and a system management module. The system performs collection and monitoring on information of the output power of a
distributed power generation unit (including a wind
turbine generator, a photovoltaic array and a
diesel engine set), the charging-discharging states of a storage battery, the load power, the
electric energy quality information of unit nodes, and the like, then carries out
data analysis and
processing under the condition of satisfying electrical characteristic constraint conditions of operating conditions and physical equipment, formulates a corresponding
optimal control strategy according to the current
microgrid operating condition and
external application requests, coordinates and manages the operations of the
distributed power supply, the load and other modules in the
microgrid system, optimizes the energy flow and utilization of the microgrid system, outputs by using renewable resources, supplies
electric energy capable of satisfying the required quality to user load at the lowest
operating cost, and realizes the
system optimization and dispatching.
