Control of Green Configuration for Isolated Telecom Tower Base Station Application

In this paper hybrid Wind/Solar/Diesel configuration as the solution to minimize the diesel fuel consumption in isolated Telecom tower base stations, is studied. To achieve high performance from wind turbine (WT) and solar panels (PVs), DC-DC boost converters are controlled using perturbation and observation (P&O) technique. All DC loads are fulfilling from the DC bus through controlled DC-DC buck converter. To balance the power in the system, lead acid batteries are connected to the DC bus through controlled DC-DC buck/boost converters. The AC-DC interfacing voltage source converter (VSC) is controlled to maintain constant the AC voltage and frequency using the symmetrical components technique-based control. Diesel generator (DG) is connected to the AC bus through static transfer switch. The performance of the proposed configuration, as well as, the control strategies are tested using Matlab/Simulink under load and weather conditions change.
