A building control system for at least one building. The building control system has a system controller and at least one building operation device with a respective operation controller. Electrical supply power is fed from a supply grid to the at least one building operation device. The system controller is set up to temporarily adapt a setpoint value for each building operation parameter in order to adapt the electrical supply power to the state of the supply grid and to stabilize the supply grid. The direct specification of a temporarily modified setpoint value for a building operation parameter is a simple and efficient option of integrating the subordinate open-loop or closed-loop controllers of the building operation devices into the building control system. This measure also makes simple retrofitting possible.

A power supply system for use in an airplane is described. The power supply system includes N alternating current (AC) power outlets configured to provide AC power output at a passenger seat in an airplane, M direct current (DC) power outlets configured to provide DC power output at the passenger seat and a controller configured to control allocation of power from a power supply to the N AC power outlets and M DC power outlet according to a phase of a plurality of phases of operation of the power supply system, where N and M are positive integers.

A method for controlling a renewable energy farm comprising a plurality of wind turbines and at least one central control unit is disclosed. The wind turbines of the renewable energy farm are connected to a power grid. The central control unit receives a request for change in operation of at least one of the wind turbines, where execution of the change in operation causes a change in power output of the wind turbine. The central control unit checks whether or not the change in power output is in conflict with at least one obligation of the renewable energy farm towards the power grid. In the case that the change in power output is in conflict with at least one obligation of the renewable energy farm towards the power grid, execution of the change in operation is deferred.

Disclosed is a coordinated peak shaving optimization method for a plurality of power supplies based on a fluctuation characteristic of a renewable energy source, including the following steps: s1: determining a weekly generated electricity quantity of hydropower based on an available capacity and a storage capacity of an electricity quantity; s2: predicting a renewable energy power generation curve and a load curve of a system weekly; s3: determining a start point of peak shaving of the hydropower based on an external transmission curve, the renewable energy generation curve, and the load curve of the system and a generating capacity of the hydropower; s4: determining a weekly peak shaving demand of the system; and s5: establishing an optimization model with a maximum peak shaving demand. The present disclosure proposes a reasonable arrangement for peak shaving, so as to resolve an accommodation problem caused by large-scale access of a renewable energy source.

Disclosed herein are AI-based platforms for enabling intelligent orchestration and management of power and energy. In various embodiments, a set of edge devices is configured to communicate with at least one energy generation facility, energy storage facility, and/or energy consumption system and automatically execute a set of preconfigured policies that govern energy generation, energy storage, or energy consumption of the respective energy generation facilities, energy storage facilities, or energy consumption systems.
