Abstract: Control system and method for integration and transition between standalone and grid-connected operations of a hybrid renewable microgrid system include a multiple-input multiple-output controller that manages a rotor-side and a grid-side converter, structured in a back-to-back configuration, alongside a DC-DC buck-boost converter. The system harnesses energy from a solar generation unit of interconnected photovoltaic panels and a wind generation unit linked to a permanent magnet synchronous generator. Both energy sources are efficiently coordinated through maximum power point tracking control. The solar unit is directly connected to a DC bus, which also interfaces with the grid-side converter. An energy storage unit is seamlessly integrated, providing power management and voltage regulation capabilities to maintain consistent power delivery and quality, even during fluctuations in renewable energy production.

Abstract: A novel renewable energy system where ambient temperatures at the surface or lower altitudes evaporate an enclosed material and create a buoyant force on the system. The buoyant system ascends and produces power. At high altitudes, the lower ambient temperature condenses the material, removing the buoyant force. The system descends to ground level, and begins the evaporation phase, starting the cycle over again.

Abstract: A hybrid solar wind power generation device includes a wind-driven module and a solar module drivingly connected with a drive shaft of a power generator. The wind-driven module has a wind-driven blade set drivable by wind power to drive the drive shaft for driving the power generator to generate power. The solar panel set has multiple solar panels arranged at intervals to drive the motor for driving the solar panel and the drive shaft to rotate. Both the wind-driven module and the solar module serve to drive the drive shaft for driving the power generator to generate power. During the process of power generation, the sunlight passes through the hollow sections between the wind-driven blades and the solar panels in rotation and project onto the ground. This improves the shortcoming that the sunlight is blocked from the space under the equipment.

Abstract: An apparatus for harvesting energy, such as solar, wind, wave, thermal, and the like, including a solar panel and a duct supporting the solar panel at an operational angle. The duct comprises a bottom shroud and side shrouds, therein forming a large aperture, a small aperture, and an oblique frustum shaped cavity. The oblique frustum shaped cavity is configured to direct a flow of fluid from the large aperture to the small aperture. A flow energy generator, such as a turbine, located at the small aperture is configured to collect flow energy. Temperature differences between the solar panel and the environment may be used to harvest thermal energy with a thermoelectric generator. Fluid flow under the solar panel may decrease the panel temperature and increase the efficiency. Generators may be operated in reverse to lower the solar panel temperature and increase efficiency.

Abstract: Repurpose decommissioned elevated highways, decommissioned elevated railways, decommissioned bridges, viaducts, and causeways and or new construction of elevated spans by making provision for providing energy from non-fossil fuel sources, such as solar, wind, geothermal and/or hydrothermal, to provide the energy needs of habitable structures and facilities built upon such decommissioned elevated bridges, elevated railways or bridges. Such is done to provide energy independence for such spans that are to be free of fossil-fuel motor vehicle traffic (or trains).
