Abstract: A precooling operation/preheating operation control apparatus includes: an air conditioner, a ventilation apparatus, and a controller. The air conditioner performs heat exchange between air in a target space for precooling or preheating and a heat medium. The ventilation apparatus replaces part of the air in the target space with outside air that is air outside a building. The controller determines, on the basis of a set temperature of the target space at a designated time and a quantity related to an outside air temperature, operation details of the air conditioner and operation details of the ventilation apparatus during a precooling operation or preheating operation.

The control system may send one or more signals to electrically disconnect the faulted region from the power grid.

Abstract: Fast simultaneous feasibility testing (SFT) for management of an electrical power grid is achieved through various innovations. The computation problem relates to evaluation of candidate solutions for external power flows into a power grid, with respect to predetermined constraints and contingencies. Storage and computations are reduced by formulating the problem in terms of transactional nodes (e.g. third party connections for generators and loads) instead of the larger number of bus nodes. Further advantages are achieved by precomputing matrices that can be reused across multiple SFT invocations, organizing matrices and operations to reduce storage and computation, and eliminating branches that have no contingency violations.

Abstract: A method for controlling at least one controllable system component in an electrical installation, where the installation is connected to an electrical supply network via a network connection. A measurement value of a performance from the supply network is detected for each individual successive time interval, and if one of the measurement values is larger than a predetermined threshold value, the performance is guided below the threshold value by switching electrical compensation power. The measurement value of the current time interval is predicted as a forecast value using a control device at at least one time within the current time interval in question by using forecast data to add a future course of the performance extending to the end of the time interval, and thereby deciding during the time interval how much compensation power is necessary.
