FAQS about Base station power supply transformation project post-evaluation

What are the evaluation methods of power transmission and transformation projects?

At present, the traditional comprehensive evaluation methods of power transmission and transformation projects mainly include scoring method, efficiency coefficient method, principal component analysis, analytic hierarchy process method, fuzzy comprehensive evaluation method and so on.

Can a base station power system model be improved?

An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters. And through this, a multi-faceted assessment criterion that considers both economic and ecological factors is established.

Does converter behavior affect base station power supply systems?

The influence of converter behavior in base station power supply systems is considered from economic and ecological perspectives in this paper, and an optimal capacity planning of PV and ESS is established. Comparative analyses were conducted for three different PV access schemes and two different climate conditions.

Can a base station power system be optimized according to local conditions?

The optimization of PV and ESS setup according to local conditions has a direct impact on the economic and ecological benefits of the base station power system. An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters.

Does loss of power converters affect the optimization of base station PV and ESS?

The main conclusions are as follows: The loss of power converters significantly affects the optimization of base station PV and ESS. Calculating with a fixed efficiency cannot accurately reflect the actual situation. The proposed evaluation method achieves a balance in LCC, initial investment, return on investment, and carbon emissions.

How ESS is connected to a base station?

Scheme 1: The classic scheme in which the base stations are only powered by grid electricity. Scheme 2: The PV modules are connected in series to obtain higher voltage and are connected to the AC bus of the base station through an inverter with MPPT function. ESS is connected to the 48 V DC bus through bidirectional DC/DC converter.
