Systems, methods, apparatuses, and computer program products for a greenhouse indoor environment controller based on model predictive control (MPC), which can be integrated into existing greenhouse regulatory systems to optimally maintain critical climatic variables, including artificial lighting levels, CO.sub.2, indoor temperature, and humidity levels within acceptable limits. The objectives of the MPC may be to maximize the rate of crop photosynthesis while optimizing the use of the available water and energy resources, taking into account the unpredictability and intermittent nature of renewable energies and external atmospheric conditions. Accordingly, certain embodiments may facilitate the management of greenhouses by anticipating control actions for a better quality of production. For that, mathematical formulations of the optimal control problem may be described, and the numerical results related to the application of the MPC to case studies are described integrating the effects of greenhouse structural considerations and the influence of climate data on its operation.

There is provided a renewable power generation farm for fishing work, the farm comprising: a plurality of mutually connected floating ships, wherein each ship is configured to generate an energy using solar and wind power, wherein each ship comprises: a main elongate floating structure; a wind-based energy generation device secured to the main elongate floating structure; a transverse beam extending perpendicularly to a longitudinal direction of the main structure; a longitudinal beam extending in a parallel manner to the longitudinal direction of the main structure; connection beams connecting both opposing ends of the transverse beam and both opposing ends of the longitudinal beam respectively; auxiliary pillars vertically extending through the both ends of the transverse beam and the longitudinal beam respectively; solar-based energy generation devices disposed at top ends of the auxiliary pillars respectively; and auxiliary elongate floating structures disposed at bottom ends of the auxiliary pillars passing through the ends of the transverse beam.

An integrated wind and solar solution is provided, including a solar energy collection assembly (100) and a vertical axis wind turbine (400), combined to provide an integrated power output. In preferred embodiments, the vertical axis wind turbine is positioned above the solar energy collection assembly. Concentrating solar mirror collectors (116) are used to direct sunlight to a heat engine (250), which converts the collected heat energy into rotary motion. Rotary motion from the heat engine and from the vertical axis wind turbine preferably are on the same rotating axis (600), to facilitate load sharing between these two sources. A dual axis azimuth-altitude solar panel alignment tracking system is used in order to boost the energy conversion capability of the solar energy collectors.

A system and method for simultaneously coordinating a wake control system and a noise control system of a wind farm having a plurality of wind turbines is disclosed. The method includes determining, via a farm controller, one or more wake control set points for the wake control system. Further, the method includes determining, via the farm controller, one or more noise control set points for the noise control system. The method also includes selecting, via the farm controller, between the wake control set points and the noise control set points for each of the plurality of wind turbines. Thus, the method also includes sending, via the farm controller, the selected control set points to local controllers of the plurality of wind turbines and operating the wind farm based on the selected control set points.

The system and method for a green integrated electric power plant mounted on rooftops, includes platform on which installed low body and upper body with gap. There are no rotatable parts for generating electric power except the propeller of generator which is affected by three air flows. The generator with propeller placed inside of upper body vertically. Low body has inside tube and spirals. Also low body has a few windows. Each window supplied by tangential plate for creating confined vortex. Thus one wind flow acting through low body directly on propeller, second air flow move warm air flow from source of warm air such as laundry or boiler room of building through conduit, inner tube and multiple Venturi tubes also act as a propeller. Third wind air flow moves perpendicular to vertical axes of generator and goes through gap between low body and upper body directly on propeller.
