Abstract
As a result of distributed energy development, the demand for energy storage grows more rapidly. The optimization of energy storage allocation is urgently needed. The economic benefits and characteristics of storage allocation have been thoroughly explored, and a mathematical model of economy was established. The centralized configuration of energy storage can make the best use of surplus electricity and reduce charging loss. The peak cutting and valley filling effect is quite obvious. Furthermore, some allocation strategies of storage were proposed. Based on the data of a user-side transformer and photovoltaic power generation, the cost under different strategies and the configuration scheme with the lowest cost is calculated. The example was used to analyze and compare the benefits under various strategies, and the results show it works in cost-saving. The strategy of similarity storage allocation has a positive effect on energy and cost-saving.

Based on the concept of shared energy storage, this paper introduces three optimization strategies to optimize the allocation of energy storage resources
Summary
With the development of new energy technology and energy interconnection technology, distributed power supply has gradually become the main development direction of the energy sector. e design of distributed power supply is widely used in the construction of isolated island microgrids such as communities, islands, and remote mountainous areas. e islanded microgrid interconnection is a network that has plural electric generation nodes, and different users have their corresponding power supply. Research [1] has proposed a novel methodology to optimize urban energy systems as interconnected urban infrastructures affected by urban morphology It can reduce the Levelized cost for energy infrastructure by up to 30%. (2) According to the investment benefit model of energy storage and optimization strategy based on power consumption similarity, an intelligent optimization algorithm is utilized to solve the proposed model. E energy storage can be charged during the peak period of power generation in the daytime and discharged at night It improves the utilization rate of electric energy and reduces the power supply pressure. E goal of energy storage optimal allocation is to solve the energy supply contradiction between the user side and the generation side and to spend as little cost as possible. Using these complementary peaks and valleys as much as possible can effectively reduce the charging and discharging times, charging and discharging depth, and the demand for the maximum energy storage capacity
