Day-Ahead Optimal Scheduling of Microgrid Based on Multi-Agent Cooperative Operation
The optimal scheduling of distributed generation can effectively reduce the environmental pollution caused by traditional generation,and also reduce the load power supply cost of the whole power grid to a certain extent.Wind and solar renewable energy and battery energy storage are jointly included in the day-ahead optimal scheduling of microgrid.Based on the in-depth study of the co-ordinated operation characteristics of different agents,the multi-agent cooperative operation of microgrid is constructed.Corresponding utility functions are established for three cooperative operators,namely distribution network operators representing external large power grids,load aggregators representing load power consumption,and distributed power operators representing renewable energy and ener-gy storage devices.It selectes the load and microgrid operation data in a certain area an actual example.By comparing the use limits of renewable energy under three different modes,scheduling models of power exchange constraint between microgrid and main network,it analyzes the utilization of wind and solar renewable energy,battery and load power supply cost under different modes.The simula-tion model built on the CPLEX simulation platform verifies that the multi-agent cooperative operation model has a good optimization effect on the daily scheduling of microgrid.
