一种储能系统an energy storage system

技术领域technical field

本实用新型属于能源储存技术领域，具体涉及一种储能系统。The utility model belongs to the technical field of energy storage, in particular to an energy storage system.

背景技术Background technique

随着国民经济的持续快速发展和人们生活水平的不断提高，电力需求量日益增长，尽管全国的发电量不断增加，但是也不能满足人们生活和工农业发展用电的需求。同时，在现实用电中也存在一个矛盾的地方：白天处于用电的高峰，电力供应严重不足，制约了工、农、商、以及运输等行业的发展；晚上11点到凌晨7点的时间段为用电的低谷，多余的电能得不到良好的利用，造成严重的资源浪费。基于上述用电矛盾，绝大多数工业城市为了避免高峰时期集中用电，鼓励企业低谷时期用电，在低谷时期的电价实行优惠政策。With the sustained and rapid development of the national economy and the continuous improvement of people's living standards, the demand for electricity is increasing day by day. Although the country's power generation continues to increase, it cannot meet the needs of people's life and industrial and agricultural development. At the same time, there is also a contradiction in the actual power consumption: during the peak of power consumption during the day, the power supply is seriously insufficient, which restricts the development of industries such as industry, agriculture, commerce, and transportation; The period is the low point of electricity consumption, and the excess electricity can not be well utilized, resulting in a serious waste of resources. Based on the above contradictions in electricity consumption, in order to avoid centralized electricity consumption during peak periods, most industrial cities encourage enterprises to use electricity during low-peak periods, and implement preferential policies for electricity prices during low-peak periods.

低谷用电可以避免电力供应不足，而且能够极大地降低电费，节约企业成本。然而，大部分企业都是白天用电高峰的时候才开业，如果要求员工上夜班，则会增加较高人力成本。Low-peak power consumption can avoid insufficient power supply, and can greatly reduce electricity bills and save business costs. However, most enterprises only open during the peak hours of electricity consumption during the day. If employees are required to work night shifts, higher labor costs will be added.
