Modelling an Embedded Control and Feasibility Study of Solar/Wind Hybrid Energy System for Rural Telephony BTS

This paper proposes a Design of an Embedded Charge Control Unit (ECCU) for a PV-solar/Wind Hybrid energy system, to provide the intermittent power supply for the telephone Base Transceiver Station (BTS) in rural areas. And also, an analytical study for modelling an optimized hybrid energy system configuration. Hybrid energy system comprises of photovoltaic solar array, wind turbine generator (WTG), diesel generator and the battery back up, are connected to centralized DC bus with the conventional power supply. To enhance the effective operation of the Hybrid power system, several operating modes have been employed in the ECCU. Analytical studies to optimize the system configuration and to identify the feasibility of the selected project location are simulated using the software called as HOMER.
