Description:
This paper presents a new mobile hybrid system using a photovoltaic array, a wind turbine, an ultracapacitor, and a battery bank for grid-independent applications in the city of Cancun, Mexico. A main controller is proposed to manage these different power sources. This controller permits autonomous operation and control over power generation and loading. This proposal used high power and high energy density storage devices, including short- and long-term storage strategies for energy management. An independent load management subsystem was added, given that the mobile application requires the management of critical loads. This subsystem included an ON/OFF pattern for the connection and disconnection of DC and AC power outlets installed inside and outside the mobile unit. In order to verify system performance, each component of the system was modeled and simulated under realistic operating scenarios with a practical load using MATLAB, Simulink, and SimPowerSystems. The results obtained for this simulation showed that, by means of power balancing, this management scheme coordinated the power flow among the different sources and the load. The manager behavior shows that the difference between the power generated and the power demand was 2.08 kW h/day and 4.01 kW h/day in winter and summer, respectively.
