Research on optimal allocation of hybrid energy storage in distribution network considering landscape absorption and carbon emission reduction
Vigorously developing renewable energy such as wind power and photovoltaic is an important way to achieve the goal of"double carbon"in China.After a large number of distributed power sources such as wind power are connected to the distribution network,the energy storage battery is used as a flexible adjustment resource,which can improve the wind absorption,carbon emission reduction and operational stability of the distribution network.In this paper,carbon emission index is proposed considering carbon emission intensity,and HES optimization configuration model of distribution network is established considering landscape consumption and carbon emission reduction.The model is solved by tabu search(TS)and improved learning factor particle swarm optimization algorithm.Finally,through the simulation analysis of IEEE-33 node distribution system,the effectiveness of the proposed method is verified.The results show that reasonable allocation of hybrid energy storage can effectively improve the wind absorption capacity,carbon emission reduction capacity and operation stability of distribution network.
