In this paper, a wind turbine-battery-dump load stand-alone renewable energy system and an optimal control of the same is presented, which enables the use of renewable energy resources, while at the same time facilitating an efficient management of energy dispatch.Abstract:
This invention provides a wind turbine-battery-dump load stand-alone renewable energy system and an optimal control of the same. The system may include both power conversion and control units. In one embodiment, the power conversion unit features a wind-turbine-driven three-phase induction generator, a diode rectifier, a battery charger, a boost dc/dc converter, a battery bank (48V), and a dc/ac inverter. A dump load is also used to dissipate excess power that is not required for either the battery charging or for the load. The integrated control unit may use the TMS320LF2407A DSP microcontroller from Texas Instruments, which allows operations of the wind power system and the battery storage system to be merged into a single package under a master controller. An embodiment of the control system features battery-charging control, battery voltage-boost control, dump load control, PWM inverter control, and system protection. It enables the use of renewable energy resources, while at the same time facilitating an efficient management of energy dispatch. This integrated control system offers remote villages the potential to fully supply their electrical power needs.read more
