Abstract To solve the capacity configuration of distributed generation in island standalone microgrid, this paper built an economic optimization model. This model takes equipment initial investment, replacement and maintenance cost, fuel cost, environment management cost, and electricity shortage penalty cost into account. And then it is solved by calling MILP solver of CPLEX, under various constraint conditions, such as renewable energy installation capacity proportion, dumped energy proportion, loss of power supply probability. Five configuration schemes are compared and analyzed. Finally, sensitivity analysis is used to investigate the effects of some system parameters on optimization results.
