چکیده
This paper explains the design of a standalone Solar/ Fuel cell/ Battery hybrid power system which involves the design of individual systems along with the power management circuit. The variation of solar insolation according to the time and the Maximum Power Point Tracking’s (MPPT) Perturb and Observe (P&O) algorithm is considered in the design of solar system. Similarly, the control of fuel flow rate according to the load and a DCDC converter is considered in the design of the fuel cell system. A battery charger is designed to protect the battery from the over and under charging from source and load respectively. All these power sources are controlled by the power management circuit, controlling the relays of each subsystem according to the load demand.

متن کاملFeasibility of Standalone Hybrid Renewable Energy System for Indian Rural Society
-The paper presents the viability of domestic standalone Photovoltaic (PV) hybrid systems in Indian rural areas. The standalone supply system powered by single nonconventional sources such as solar, wind turbines or tidal face unpopularity due to the inconsistency and undependable variance in their source throughout the day/year. The above drawbacks can be addressed by combining minimum of two ...
