Ultimately

the research on microgrid is to find the good solution for coping with the series issues from scarcity of both energy and natural resource to sever environmental deterioration nowadays

and so on. The microgrid’s development is not only to meet the basic demand of power supply

but also to enhance both the economy and the environmental protection. Through the establishment of the environmental protection model and economic model

the optimization of distributed power supply has been achieved by optimized operation for distributed generation of this system

and then by optimizing the computing model using genetic algorithm

which are on the condition of being constrained. The results of example are compared by different optimized results within 24 hours and get the optimization. As a consequence

the optimization of the whole microgrid has been improved accordingly

so as to achieve the whole optimal operation.
