What is the nominal capacity of a base station energy storage?
The nominal capacity of the base station energy storage is 20 kWh, and the number of the base station in each operating state is 500. The SOC values of the base station obey normal distribution between 0 and 1 in each operating states. This paper takes ( {text {SOC}}_ { {i,min }} = 0.3 ) and ( {text {SOC}}_ { {i,max }} = 0.9 ).
What is the primary responsibility of the base station energy storage?
The primary responsibility of the base station energy storage is to protect the power supply of the base station, so the dynamic backup capacity of the base station in real time will be considered in the future. Chen, X.; Lu, C.; Han, Y.: Power system frequency problem analysis and frequency characteristics research review.
Can base station energy storage be used as Fr resources?
Although the power output of a single base station storage is limited, the combined regulation of large-scale base stations can have a significant meaning. Therefore, the base station energy storage can be used as FR resources and maintain the stability of the power system.
Can a bi-level optimization model maximize the benefits of base station energy storage?
To maximize overall benefits for the investors and operators of base station energy storage, we proposed a bi-level optimization model for the operation of the energy storage, and the planning of 5G base stations considering the sleep mechanism.
What are the basic parameters of a base station?
The fundamental parameters of the base stations are listed in Table 1. The energy storage battery for each base station has a rated capacity of 18 kWh, a maximum charge/discharge power of 3 kW, a SOC range from 10% to 90%, and an efficiency of 0.85.
What is the energy saving strategy of base station?
In [ 20 ], the energy saving strategy of base station is proposed considering the variability and complementarity of base station communication loads. This strategy helps the power system to cut peaks and fill valleys while reducing base station operating costs.
