Optimal Ratio of Wind-Solar-Storage Capacity Considering the Uncertainty of Renewable Energy
摘要
Abstract
Due to the influence of weather conditions on the supply of wind and solar energy,the distribution of wind-solar-storage capacity exhibits significant uncertainty.Existing capacity allocation methods often overlook the constraints imposed by this distribution characteristic and solely rely on multi-constraint solution models involving power,which may lead to fluctuations in results and pose difficulties in accurately calculating the capacity allocation of energy storage systems.To address this issue,a method for optimizing the capacity allocation of wind-solar-storage systems that considers the uncertainty of renewable energy is proposed based on the design of an optimal capacity distribution calculation method for batteries.Firstly,the models for wind power generation and photovoltaic power generation are established,and a battery capacity distribution model is constructed based on their interrelationships to estimate the optimal output power distribution and derive the optimal battery capacity distribution accordingly.Then,with full consideration of the uncertainty of renewable energy,an optimization model for capacity allocation with the objective function of maximizing total power generation is constructed by using the optimal capacity distribution as a constraint.Finally,by utilizing constraints to ensure consistency between output power and load variation characteristics,the optimal installed capacity is obtained,and the optimal capacity allocation for wind-solar-storage systems is realized.Experimental results demonstrate that the proposed method can effectively achieve optimal capacity allocation for wind-solar-storage systems,and ensure normal power supply demand while avoiding waste of renewable energy,thereby providing a new strategy for stable grid operation and efficient resource utilization.关键词
