Optimal configuration for photovoltaic storage system capacity in 5G
The configuration of the 5G base station microgrid photovoltaic storage system can not only meet the energy storage requirements of the 5G base stations, but also reduce the
From the above comparative analysis results, 5G base station operators invest in photovoltaic storage systems and flexibly dispatching the remaining space of the backup energy storage can bring benefits to both the operators and power grids.
The photovoltaic storage system is introduced into the ultra-dense heterogeneous network of 5G base stations composed of macro and micro base stations to form the micro network structure of 5G base stations .
The outer model aims to minimize the annual average comprehensive revenue of the 5G base station microgrid, while considering peak clipping and valley filling, to optimize the photovoltaic storage system capacity. The CPLEX solver and a genetic algorithm were used to solve the two-layer models.
Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .
