A Novel Microgrid Energy Management Method Based on Hierarchical Timed Colored Petri Net Under Multiple Natural Scenarios

In order to explore the operational characteristics of the microgrid in different natural scenarios, this paper proposes an energy management method for the wind-solarstorage microgrid based on hierarchical timed colored Petri net (HTCPN). Firstly, the model of HTCPN is constructed according to the actual operation mode of the microgrid. Secondly, a region's typical environment and load information in four seasons are used as the input data of the model. A wide range of simulation experiments is performed on CPN TOOLS platform to reduce interference from randomness. Then, the operating costs of the model and the output power of each unit within it are obtained. Finally, based on the output data, four evaluation indexes are calculated to quantitatively analyze the operation characteristics of the microgrid. The results of simulation experiments indicate that this method can effectively reflect the distinctive operational characteristics of the microgrid in different scenarios. Moreover, by automatically simulating the operation of a practical microgrid, the operational status of units can be observed.
