Background
▪ The upgrade of communication equipment room requires equipment room renovations to reduce rental costs;
▪ The smaller coverage of 5G requires a station density 3-4 times that of 4G and increases total energy consumption over 9-fold, resulting in soaring costs for operators;
▪ The expansion of simplified network sites, combined with a lack of backup power and potential external power failures, presents new challenges on network stability;
▪ Despite adjustments to Time-of-Use pricing policies, most base stations maintain their original power supply mode and fail to capitalize on the price difference.
Introduction of Simplified Power Supply Solution
▪ Solution 1: Add solar-grid System solar energy hybrid system on the existing power system;
▪ Solution 2: If the power supply of the base station is unavailable in the past, rebuild the whole power supply system;
▪ It achieves triple guarantees through photovoltaic power generation (solar), energy storage batteries (storage), and grid power collaboration (backup), realizing "power generation - energy storage - power consumption - backup power supply."
Principles
▪ Under sufficient photovoltaic conditions, the DC/DC module prioritizes solar power for base station DC loads during all periods (peak, off-peak, flat, or valley). When solar power is insufficient, the system supplements with energy storage batteries or mains power according to electricity pricing periods.
▪ The energy storage battery mainly realizes peak shaving and valley filling for the base station through the charging and discharging function, saving energy and reducing costs. The working logic is as follows:
- During the Peak periods, the Energy Storage Hybrid System powers the load;
- During the Average periods, the grid powers the load;
- During the Valley periods, the grid powers both the load the energy storage battery at the same time;
▪ During cloudy or rainy days or when there is a power outage, the energy storage battery can also serve as a backup power source for base stations, providing emergency power supply. In addition to meeting daily energy storage and discharge needs, it retains some capacity for backup battery purposes.
Components
▪ Based on actual solar exposure duration, load power, electricity rates, investment targets, and the required configurations of PV modules, MPPT modules, DC/DC converters, AC/DC converters, and battery capacity.
