Comprehensively considering the optimal allocation scheme and operation strategy of lithium battery energy storage system
an optimal allocation model of lithium battery cloud-edge collaborative energy storage system is proposed
which takes into account economic performance and reliability. Firstly
a mathematical model is established with the objective functions of the cost of the lithium battery cloud-edge collaborative energy storage system
the benefit of energy release by the energy storage system and the reliability of the power grid. On this basis
considering the constraints of distribution network and energy storage system
lithium battery cloud-edge collaborative energy storage system is optimized to improve the absorption capacity of renewable energy such as photovoltaic power and improve the stability of the power system. Secondly
SPEA2-SA algorithm was used to solve the multi-objective model to find the optimal solution of lithium battery cloud-edge collaborative energy storage system under the multi-objective situation
overcome the power grid fluctuation problem
and obtain the optimal allocation and operation scheme of the energy storage system. Finally
using the above research model and algorithm
the IEEE-33 node model is used to conduct simulation experiments on the effectiveness of the lithium battery cloud-edge collaborative energy storage system. The simulation results of the example show that the optimal allocation scheme of the lithium battery cloud-edge collaborative energy storage system optimized by the SPEA2-SA algorithm can significantly reduce the operating cost and effectively improve the operating stability of the photovoltaic power grid
thus validating the superiority and effectiveness of the SPEA2-SA algorithm.
