Optimization strategy of economic operation of fishery microgrids under the background of"marine pastoral fields"
For the aquaculture raft microgrid system in the"marine pastoral fields",a model of microgrid cluster systems is proposed.Addressing the challenges of maintaining stable power supply and economic bene-fits in the special environment without the support of a large grid,two economic objective functions are intro-duced,which take into account the power dispatching between microgrids and their economic benefits.The non-dominated sorting genetic algorithm Ⅱ(NSGA-Ⅱ)and the constraint multi-objective evolutionary algo-rithm based on decomposition(CMOEA/D)are applied to solve the objective functions.Results indicate that the CMOEA/D algorithm demonstrates higher efficiency and accuracy in pursuing economically optimal solu-tions,outperforming the NSGA-Ⅱ algorithm in both the quality of the optimal solutions and the iterative time,thereby verifying the effectiveness of the proposed model and algorithms.
