In addition, the existing multi-objective algorithm generally converts the multi-objective problem into a nonlinear single-objective optimization problem based on the linear summation of multiple objectives or based on the fuzzy membership function; but in these two methods, the linear weighting coefficient depends on the empirical design , has great uncertainty, and the selection of fuzzy membership function is very complicated. How to make a reasonable comprehensive evaluation of multiple performance indicators of the new energy supply system determines the execution process of the optimization algorithm and the quality of the optimization results. satisfaction level
