Abstract:

The multi-energy complementary system integrating wind, solar, and energy storage technologies optimizes the use of renewable energy resources, enhancing both economic and environmental benefits. This study proposes a multi-energy complementary system model that incorporates wind, solar, and energy storage. The objective is to minimize the system's overall cost and carbon emissions, addressing both economic and environmental concerns. An improved non-dominated genetic algorithm is developed to obtain the Pareto optimal solution set for the multi-objective optimization problem. The optimal capacity configuration and operation scheme are determined using the technique for order preference by similarity to ideal solution. The system's operation scheduling is optimized using the CPLEX solver, a linear programming software, to validate the effectiveness and accuracy of the proposed system framework and scheduling model. Results demonstrate that the proposed optimization method significantly enhances renewable energy utilization, minimizes economic costs and carbon emissions, and improves the system's economic and environmental performance. This research offers valuable insights for the sustainable, stable, and reliable energy supply of renewable energy systems and supports the low-carbon transition of industrial parks.
