Smart Microgrid System for a Telecom Base Station

The following is a presentation of the design and implementation of a Smart Microgrid system specific for supplying telecommunication Base Transceiver Stations (BTS) with power in the context of an unreliable grid supply, as in the case of Lebanon. The system integrates renewable solar power with Battery Energy Storage Systems (BESS) and a dynamic Energy Management System (EMS) deployed on a Raspberry Pi with Node-RED. The system tracks real-time weather
conditions and battery state-of-charge (SoC) in order to make smart decisions on the distribution of the energy sources with the aim of sustainability, cost-effectiveness, and zero-service disruptions. A weather forecasting API allows the system to prepare in advance for low sun availability, with multi-level load shedding ensuring vital operations remain maintained in periods of shortage. A thorough analysis of PV capacity, battery capacity, power conversion and system behavior under different operational modes is presented. The outcome is a modular and scalable system that is capable of decreasing the dependence on diesel and operating costs for telecom companies, as well as on driving Lebanon’s transition towards sustainable energy infrastructure.
