Claim 8:
9. A controller for regulating environmental systems, comprising:
at least one processor; and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the controller at least to:
create, at the same time, a distinct microclimate in each of a plurality of greenhouses that are networked together, wherein the distinct microclimate in each of the plurality of greenhouses is created by defining a lighting power reference signal of a lighting power, a carbon dioxide concentration reference signal of a carbon dioxide concentration, and a temperature reference signal of a temperature tailored for a specific crop in a each of the plurality of greenhouses;
receive renewable resource information related to each of the plurality of greenhouses, wherein the renewable resource information comprises water load information for each of the plurality of greenhouses from a water reservoir;
receive dynamic weather information of an environment external to each of the plurality of greenhouses;
integrate, in each of the plurality of greenhouses, the lighting power reference signal, the carbon dioxide concentration reference signal, the temperature reference signal, the renewable resource information, and the dynamic weather information into the controller configured to control the distinct microclimate in each of the plurality of greenhouses;
determine an optimization control scheme for the specific crop that satisfies the lighting power reference signal, the carbon dioxide concentration signal, and the temperature reference signal while taking into account the renewable resource information and the dynamic weather information;
dynamically regulate the lighting power, the carbon dioxide concentration, and the temperature in each of the plurality of greenhouses according to the optimization control scheme;
dynamically control the water reservoir between a discharging mode and a charging mode based on time and an electric power load of the environmental systems; and
determine an amount of water flow entering the water reservoir based on power consumed by a main pump of the environmental system,
wherein the carbon dioxide concentration is dynamically regulated according to different phases of growth of the specific crop.
