Optimized Scheduling of Photovoltaic-integrated Microgrids Using Petri Nets
Most conventional optimized scheduling methods for PV-integrated microgrids are designed based on XGBoost principle and limited in applicability,as the scheduling quality and efficiency are insufficient,resulting in some microgrid nodes'voltage exceeding the limit and not reaching upper and lower limits after scheduling,and consequently low qualification rate microgrid voltage and increased losses.In view of this a new microgrid optimization scheduling method is proposed by introducing Petri nets.First PV-integrated microgrid is modeled and dynamic changes and inherent characteristics of microgrid are obtained.Second changes in operating modes of various distributed units within the microgrid are described using Petri nets to help schedule microgrid energy.On that basis,interactive power constraint conditions for microgrid active power optimized scheduling are determined.The application of the proposed scheduling method is proved by experiments capable of achieving satisfactory restraint of microgrid node voltage values within acceptable upper and lower limits,thus improving voltage qualification rate and reducing network losses.
