Research on Multi-Objective Optimization Strategies for Electrical New Energy Microgrids
Due to the instability of new energy and fluctuations in energy demand,it is difficult to ensure the active power of electrical new energy microgrids.Therefore,a multi-objective optimization strategy research for electrical new energy microgrids is proposed.Based on the objective situation of the electrical new energy microgrid,an objective function is constructed,constraint functions are set,and a hierarchical control method is adopted in the optimization management stage(divided into two parts,bottom level control and upper level control).When the range of load and power generation changes does not exceed the allowable range of autonomous control regulation,the output of each power generation unit is directly controlled by the bottom level control.Otherwise,the upper level control should be applied to adjust the output of the energy storage unit.The results show that the active power of the new energy grid exhibits high stability,and the corresponding parameters remain above 2.70×105 W.
