ENERGY SYSTEM CONTROL

The disclosure concerns a controller arranged to control an energy system where the energy system included one or more first energy operators and one or more second energy operators, an energy storing system and an energy storing system monitoring device. The controller is arranged to have control over variation in operation of the one or more first energy operators and variation in operation of the second energy operators is at least partially beyond the control of the controller. At least one of the energy operators is an energy supply system and at least one and the remainder of the energy operators are energy consuming systems. At least two of the energy operators are variable energy operators. Where an energy supply system is a variable energy operator, variation in operation of that energy supply system adjusts the energy it supplies. Where an energy consuming system is a variable energy operator, variation in operation of that energy consuming system adjusts the energy it consumes. Outputs of the energy supply systems, inputs of the energy consuming systems and a connection of the energy storing system are connected by a common connection such that they are maintained at the same potential. The energy storing system is arranged to provide energy to the common connection to compensate where there is a deficit in energy supplied by the at least one energy supply system as compared with the energy demand from the at least one energy consuming system. The controller included an input arranged to receive a data signal indicative of the power output of the energy storing system from the energy storing system monitoring device; a processing system arranged to determine, in accordance with the energy storing system power output data received, whether and to what extent there is a deficit which exceeds an energy storing system discharging set point value, and where there is, a variation in control for at least one of the first energy operators corresponding in magnitude to the determined extent of the deficit to compensate and return the deficit to the energy storing system discharging set point value; and an output via which the processing system sends one or more control signals to control the at least one of the first energy operators accordingly. a variation in control for at least one of the first energy operators corresponding in magnitude to the determined extent of the deficit to compensate and return the deficit to the energy storing system discharging set point value; and an output via which the processing system sends one or more control signals to control the at least one of the first energy operators accordingly. a variation in control for at least one of the first energy operators corresponding in magnitude to the determined extent of the deficit to compensate and return the deficit to the energy storing system discharging set point value; and an output via which the processing system sends one or more control signals to control the at least one of the first energy operators accordingly.
