Study on the Design of Field Wind-PV Hybrid Power Storage & Supply System

To guarantee the continuous supply of power and solve the problem of limited energy supply in field operations, the design implements a portable field wind-PV hybrid power storage & supply system. Through a comparative analysis on MPPT control techniques, it selects a control method applicable to the system. Based on service environment, user demands and an estimate of solar power storage & supply capacities, it designs three forms of series prototypes, i.e., vehicle-mounted, mobile and portable; it also provides optimization for structural design, and adopts a foldable solar panel structure to meet the requirements of portable and vehiclemounted design. As indicated by the results, the differences among the three forms of series prototypes in terms of power storage & supply capacities and structure can not only guarantee user's power consumption demand and make them easy to carry, but also enhance the diversity of user options, which further testifies to the correctness and effectiveness of system design and control strategy.
