1. An electric/thermal energy storage schedule optimizing device comprising:

  • a predicting unit setting predicted values of a consumed energy of a plurality of control-target devices based on a comparison between a control setting value set by a setting unit and a past control setting value or setting predicted values of a supplying energy of the plurality of control-target devices based on the comparison between the control setting value set by the setting unit and the past control setting value; and

    a start-stop optimizing unit creating start-stop schedules of the plurality of control-target devices based on the predicted values set by the predicting unit,wherein the start-stop optimizing unit further comprises;

    a start-stop condition setting unit setting start-stop conditions of the plurality of control-target devices in accordance with cold heat and hot heat consumed energy based on an activation preference order of the plurality of the control-target devices determined based on a predetermined evaluation index;

    an activation-device allocating unit allocating the plurality of the control-target devices to be activated at each clock time based on the start-stop conditions and the predicted values;

    a production-unit-price collecting unit computing a cold heat production unit price of a control-target device with a lowest activation preference order among the plurality of the control-target devices to be activated at each clock time;

    a heat-storage/heat-dissipation allocating unitallocating heat storage to clock times in an order beginning with a lowest cold heat production unit price and allocating electricity storage to clock times in an order beginning with the lowest cold heat production unit price, andallocating heat dissipation to clock times in an order beginning with a highest cold heat production unit price and allocating electricity dissipation to clock times in an order beginning with the highest cold heat production unit price;

    an activation-boundary-condition setting unit that sets an activation boundary condition which is a condition for activating each control-target device based on a characteristic of the control-target device and the activation preference order; and

    a deactivation-boundary-condition setting unit thatsets a deactivation boundary condition which is a condition for deactivating each control-target device based on the characteristic of the control-target device and the activation preference order, andsets a deactivation dead zone between the activation boundary condition and the deactivation boundary condition by making a value of the deactivation boundary condition smaller than a value of the activation boundary condition within a range which the control-target device with a highest activation preference order is not lower than a lower limit output.
