A Planning Method for Stand-alone Wind-solar Hydrogen Storage System Based on 8760 Hours Production Simulation
Hydrogen production from renewable sources like solar and wind energy is a crucial component of China's commitment to the"dual-carbon"objectives and the promotion of green industrial development.The establishment of stand-alone Wind-Solar-Hydrogen-Storage system industrial parks offer a practical solution for harnessing renewable energy locally,which relieves the pressure on expanding the power grid.In the planning of stand-alone parks that lack the support of power grids,realizing the planning solution based on the production simulation of 8760 hours in a year,and rationally configuring the two types of hydrogen production equipment are important technological issues.This paper addresses the planning methodology for stand-alone wind hydrogen storage parks,proposing a planning model based on 8760-hour production simulation and solving it through model transformation and enhanced Benders decomposition techniques.Initially,an integrated model for the operation planning of stand-alone wind-hydrogen storage systems was developed,considering the differences in the dynamic characteristics of different electrical hydrogen production equipment.To simplify the computational process,public operation variables are introduced at the primary planning layer,while the operation layer is divided into monthly sub-problems to reduce model complexity.Ultimately,the model is solved using the Benders decomposition method.The effectiveness of this proposed planning approach for stand-alone wind-hydrogen storage systems is validated through a practical case study in Weifang City,Shandong province.Results demonstrate its ability to optimize equipment capacity planning based on an 8760-hour production simulation,leading to reduced lifecycle costs for the park.This approach rationalizes the configuration of hydrogen production equipment with different operational capabilities and improves the economics of stand-alone hydrogen production systems.
