  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an operation plan planning apparatus and an operation plan planning method for a heat source facility in an exhaust heat utilization system according to the present invention will be described with reference to the drawings.

<Embodiment 1>
FIG. 1 shows an overall configuration of Embodiment 1 of an operation control system (operation plan planning device) for a heat source facility according to the present invention.

  The operation control system (operation planning device) 101 of the heat source equipment shown in FIG. 1 is operated with the waste heat utilization heat source equipment preferentially using waste heat on the premise that the waste heat utilization heat source equipment is used. In the waste heat utilization system that does not, the operation plan of the heat source facility is considered in consideration of the energy consumption characteristics that fluctuate according to the amount of waste heat water used by the waste heat utilization heat source facility. This heat source facility operation control system 101 mainly includes an optimum calculation data creation unit 104, a heat source facility optimum computation model creation unit 102, a waste heat utilization heat source facility optimum computation model creation unit 103, and an optimum computation unit. And 105.

  The optimum calculation data creation unit 104 uses the external data 106 such as temperature including temperature and weather information and the heat source facility parameter 107, and the equipment not subject to the optimum calculation (for example, a cooling tower that is a cooling water supply source, Solar power generation panels that use (use) natural energy, other facilities that have a predetermined operation plan, etc., and that require output information as information when planning an operation plan) And the calculation result is transmitted to the heat source equipment optimal calculation model creation unit 102 and the optimal calculation unit 105.

  The heat source equipment optimum computation model creation unit 102 uses the computation result of the optimum computation data creation unit 104, the external data 106 such as the temperature, and the heat source equipment parameter 107, and the conventional heat source equipment used for the optimum computation (heat source using exhaust heat). A heat source facility optimal calculation model for a heat source facility other than the facility) is created, and the created result is transmitted to the optimum computation unit 105.

  On the other hand, the exhaust heat utilization heat source equipment optimal calculation model creation unit 103 uses the external data 106 such as temperature and the exhaust heat utilization heat source equipment characteristic data 108 to determine the energy consumption characteristics of the exhaust heat utilization heat source equipment that is the target of the optimum computation. A specified exhaust heat utilization heat source facility optimum computation model is created, and the creation result is transmitted to the optimum computation unit 105.

  The optimum computation unit 105 includes the computation result (heat output, etc.) transmitted from the optimum computation data creation unit 104, and the creation result (heat source facility optimum computation model) transmitted from the heat source facility optimum computation model creation unit 102. Based on the creation result (model for optimum computation of exhaust heat utilization heat source equipment), the predicted heat demand 109, and the objective function designation instruction 110 by the user, etc. For example, an operation plan of the heat source facility is created using an optimization method such as a mixed integer programming method, and the creation result (operation plan 111) is output to a display panel or the like disposed in a heat consumer or the like.

  The external data 106 such as temperature, the heat source equipment parameter 107, the exhaust heat utilization heat source equipment characteristic data 108, and the predicted heat demand 109 are stored in advance in a storage unit (not shown) or the like provided in the operation control system 101. ing.

  FIG. 2 illustrates the processing flow of the operation control system 101 for the heat source equipment shown in FIG. Note that this processing flow is periodically executed every predetermined time.

  As shown in FIG. 2, in the heat source equipment operation control system 101 of the first embodiment, first, the optimum calculation data creation unit 104 uses the external data 106 such as temperature and the heat source equipment parameters 107 to optimize the heat source equipment. The cooling tower temperature that contributes to the calculation model, the heat output of the equipment not subject to the optimal calculation, and the like are generated (S201). In addition, as equipment that is not subject to such an optimal calculation, for example, a cogeneration system that operates according to a predetermined schedule and outputs electric heat, cooling water at a temperature determined by the outside wet bulb temperature is output. Cooling towers, solar panels using renewable energy, solar collectors, etc. In addition, the cogeneration system can be included in the heat source equipment that is the target of the optimum calculation.

  Next, the heat source equipment optimum computation model creation unit 102 optimizes the heat source equipment of the conventional heat source equipment (heat source equipment other than the heat source equipment using exhaust heat) used for the optimum computation based on the external data 106 such as temperature, the heat source equipment parameter 107, etc. A calculation model is created (S202). Note that these conventional heat source facilities (heat source facilities other than waste heat utilization heat source facilities) have their energy consumption (consumption of steam, electricity, gas, etc.) relative to the load factor if the above-mentioned external condition data is determined. Is a facility that is uniquely determined.

  Next, the exhaust heat utilization heat source facility optimum calculation model creation unit 103 creates the exhaust heat utilization heat source facility optimum calculation model used in the optimum calculation using the exhaust heat utilization heat source facility characteristic data 108 and the external data 106 such as temperature. (S203).

  Next, the optimum computation unit 105 uses the heat source facility optimum computation model creation unit 102 and the exhaust heat utilization heat source facility optimum computation model creation unit 103, and the exhaust heat utilization facility heat source facility optimum computation. The model information is used to optimize the operation plan according to the objective function specified by the user with external conditions such as the predicted heat demand 109 as constraints, and the created operation plan is external (for example, to heat consumers, etc.) (S204).

  The optimum computing unit 105 determines whether or not the heat source equipment parameter has been changed by the user or the like (S205), and when it is determined that the heat source equipment parameter has been changed, the heat source equipment parameter is updated. Later (S206), the operation plan is optimized again.

  Here, the energy consumption characteristics (energy consumption relative to the load factor) of the waste heat utilization heat source equipment considered when creating the exhaust heat utilization heat source equipment optimum computation model by the exhaust heat utilization heat source equipment optimum computation model creation unit 103 is shown in FIG. 3 and FIG.

  FIG. 3 shows an example of the energy consumption characteristics of the waste heat water of the waste heat utilization heat source facility. In FIG. 3, the exhaust heat utilization heat source facility can sufficiently use the exhaust heat (exhaust hot water) under each condition where the cooling water inlet temperature and the cold water outlet temperature are different, that is, the exhaust heat utilization heat source facility. This shows the case where the amount of exhaust heat (waste water) is the maximum.

  As shown in the figure, the waste water consumption of exhaust heat utilization heat source equipment that uses waste heat water generally changes from increasing to decreasing at a certain load factor (operation output (actual output) / rated output). That is, the waste water consumption characteristic of the waste heat utilization heat source facility has a characteristic of forming a polygonal line with a certain load factor as a boundary. In this waste water consumption characteristic, the load factor at which the waste water consumption takes an extreme value (maximum value) (in this specification, described as the waste heat water load factor division point) is the cooling water used by the waste heat utilization heat source equipment. It changes depending on the temperature (cooling water inlet temperature) and the outlet side temperature (cooling water outlet temperature) of the cold water to be output. When exhaust water is used sufficiently, the energy consumption characteristics at that time are uniquely determined. However, when exhaust water is not used sufficiently, the waste water load factor division point decreases. That is, when the exhaust hot water cannot be used sufficiently, the energy consumption characteristics of the exhaust heat utilization heat source facility fluctuate in the same manner as the change of the energy consumption characteristics with respect to the change of the cooling water inlet temperature and the cold water outlet temperature. Note that there are cases where the start / stop operation is repeated for output and stop when the load is below the minimum load rate, which is the minimum value of the load that can be operated normally, and FIG. 3 also shows the characteristics at that time.

  FIG. 4 shows an example of the energy consumption characteristics of steam or gas in the exhaust heat utilization heat source facility. In FIG. 4, as in FIG. 3, the exhaust heat utilization heat source facility can sufficiently use the exhaust heat (exhaust hot water) under each condition where the cooling water inlet temperature and the cooling water outlet temperature are different. This shows the case where the amount of exhaust heat (exhaust hot water) used by the heat-use heat source facility is the maximum.

  In the exhaust heat utilization heat source equipment, steam or gas is consumed to make up for the shortage that cannot meet the heat demand only with the above-described exhaust hot water, so the energy consumption is as shown in FIG. Increase from the waste water load factor division point. That is, the energy consumption characteristics of the exhaust heat water load that varies depending on the temperature of the cooling water used by the exhaust heat utilization heat source equipment (cooling water inlet temperature) and the outlet temperature of the cold water that is output (cold water outlet temperature). From the rate dividing point, it has a characteristic of increasing with respect to the load factor. When the exhaust water is used sufficiently, the energy consumption characteristics at that time are uniquely determined. However, when the exhaust water is not sufficiently used, the cooling water inlet is similar to the energy consumption characteristics of the exhaust water shown in FIG. It fluctuates similarly to the change of the energy consumption characteristic with respect to the change of the temperature and the cold water outlet temperature (in FIG. 4, it fluctuates so as to translate in the vertical axis direction).

  The processing flow of the operation control system 101 of the heat source facility shown in FIG. 2 will be described in more detail in consideration of the energy consumption characteristics of the exhaust heat utilization heat source facility described based on FIG. 3 and FIG. The data creation unit 104 generates the heat output of the equipment that is not subject to the optimal calculation (S201).

  Next, the heat source equipment optimum computation model creation unit 102 creates a heat source equipment optimum computation model for a heat source equipment other than the exhaust heat utilization heat source equipment using the external data 106 such as temperature, the heat source equipment parameter 107, and the like (S202).

  For example, FIG. 5 shows an example of the power consumption characteristics of a screw refrigerator that is a heat source facility other than the exhaust heat utilization heat source facility, and FIG. 6 schematically shows a piecewise linear approximation of the heat source facility optimum calculation model. This is the explanation.

  The value of the minimum load factor shown in FIG. 5 is defined for each facility. When the value is below this minimum load factor, the screw refrigerator performs start / stop operation that repeats operation and stop. When the screw refrigerator is operated in such a region below the minimum load factor, the heat source facility optimum calculation model creation unit 102 inputs a curve approximating the characteristics to the heat source facility optimum calculation model. . On the other hand, when the operation of the screw refrigerator is not considered in the region below the minimum load factor, the heat source facility optimum calculation model creation unit 102 does not input the characteristics to the heat source facility optimum calculation model.

  In addition, the heat source equipment optimal calculation model creation unit 102 creates a piecewise linear approximation model as shown in FIG. 6 in a region exceeding the minimum load factor, and creates each heat source equipment optimum calculation model. The intercept is output to the optimum computation unit 105. Note that when the optimal calculation unit 105 can perform nonlinear optimization without using, for example, linear mixed integer programming, the coefficient representing the equation of the curve shown in FIG. .

  For heat source equipment such as steam absorption refrigerators and gas fired absorption chiller / heaters, curves of the same format as the curves shown in FIGS. 5 and 6 (in this case, the vertical axis indicates steam consumption or gas consumption). ) Can represent its energy consumption characteristics.

  Next, the exhaust heat utilization heat source facility optimum computation model creation unit 103 creates an exhaust heat utilization heat source facility optimum computation model using the energy consumption characteristics of the exhaust heat utilization heat source facility shown in FIGS. 3 and 4 (S203). . The exhaust heat utilization heat source facility characteristic data 108 includes information for that purpose, and among the information included in the exhaust heat utilization heat source facility characteristic data 108, the parameters for modeling the energy consumption characteristics shown in FIG. A parameter that defines the following equation (1) that expresses the variation of the hot water load factor division point depending on the chilled water outlet temperature and the cooling water inlet temperature, and a parameter related to the slope of the waste water consumption amount when the hot water load factor division point is below or above The parameter etc. regarding the consumption characteristic of the waste water at the time of start / stop operation are mentioned. In order to model the energy consumption characteristics in more detail, the energy consumption characteristics of the exhaust water are approximated by a curve instead of a straight line, and parameters relating to the curve are input to the model creation unit 103 for calculating the optimum heat source equipment for exhaust heat utilization. Also good.

[Equation 1]

In equation (1), t represents time, x _{M_mh_max} represents the waste water load factor division point, T _c represents the cold water outlet temperature, and T _cl represents the cooling water inlet temperature.

  In addition, the parameters for modeling the energy consumption characteristics shown in FIG. 4 are basically the following, which indicates the consumption of steam or gas that varies depending on the load factor and varies depending on the chilled water outlet temperature or the cooling water inlet temperature. The parameter which defines Formula (2) is mentioned.

[Equation 2]

  In equation (2), GorS represents the consumption of gas or steam, and x represents the load factor.

  The exhaust heat utilization heat source equipment optimum calculation model creation unit 103 generates the characteristic curves shown in FIGS. 3 and 4 using the information included in the exhaust heat utilization heat source facility characteristic data 108 and the like, and then the optimum computation unit 105 A predetermined process for using the characteristic curve for the calculation of the operation plan is executed.

  Specifically, when the optimal calculation unit 105 uses a non-linear programming method when generating an operation plan, the exhaust heat utilization heat source equipment optimal calculation model creation unit 103 uses the obtained characteristic curve as it is. On the other hand, when the optimal computation unit 105 uses linear programming when creating an operation plan, the model creation unit 103 for optimum calculation of exhaust heat utilization heat source equipment linearizes the model created from the obtained characteristic curve. Execute the process.

  For example, FIG. 4 shows a curve determined by the chilled water outlet temperature and the cooling water inlet temperature when the exhaust hot water is sufficiently used, but the characteristic curve when the exhaust heat cannot be sufficiently used Using the fact that a curve approximating the characteristic curve when fully used becomes almost equal to the curve translated in the vertical axis direction, the steam consumption can be described as shown in the following equation (3). . In this example, the equation of consumption is approximated by a quadratic function with respect to the load factor.

[Equation 3]

Here, in Expression (3), α is a coefficient for taking into account changes in the curve that change depending on the cold water outlet temperature. A ₁ and A ₂ are coefficients for determining the basic curve shape, and are factors for determining the basic curve shape when α is 1 (at the time of rated chilled water outlet temperature). It is. Β is a constant that represents the movement in the vertical axis due to the change in the waste water load factor division point, and is expressed by the following equation (4) using the waste water load factor division point x _mh at which the steam consumption is zero. Is done.

[Equation 4]

  The exhaust heat utilization heat source facility optimum calculation model creation unit 103 receives these coefficients as the exhaust heat utilization heat source facility characteristic data 108, performs a piecewise linear approximation using the characteristic curve obtained here in the same manner as in FIG. The coefficient is transmitted to the optimum computation unit 105. As in S202 described above, when the optimum computing unit 105 can perform nonlinear optimization without using, for example, linear mixed integer programming, the coefficient representing the equation of this curve is output to the optimum computing unit 105 as it is. May be. Accordingly, it is possible to use a heat source facility optimum calculation model that takes into consideration exhaust heat consumption characteristics that change according to the amount of exhaust heat (exhaust hot water) used.

  Then, the optimization calculation unit 105 performs an optimization calculation of the operation plan using a generally used mixed integer linear programming method or the like (S204). However, the operation plan calculation method by the optimum calculation unit 105 is not limited to this, and the operation plan optimization calculation may be performed using, for example, nonlinear optimization, heuristic, or the like.

Specifically, the optimal calculation unit 105 is used for the same condition of utility demand and supply, or for optimal calculation of heat source equipment so as to minimize an objective function (specified by the user) such as cost and CO ₂ emission amount. An operation plan optimization calculation is performed based on a constraint equation defined by the equipment model created by the model creation unit 102 and the exhaust heat utilization heat source equipment optimum computation model creation unit 103. For example, when calculating the solution by the mixed integer linear programming, the optimal calculation unit 105 loads the model created by the exhaust heat utilization heat source facility optimal calculation model creation unit 103 as shown in the following equation (5). The calculation can be optimized by dividing the rate into two.

[Equation 5]

In equation (5), x _mh represents the waste water load factor division point as in equation (4), and x _st represents the remaining load factor.

When the amount of waste water used is small, it is possible to simulate changes in the energy consumption characteristics of the waste heat utilization heat source equipment by moving the waste heat water load factor division point x _mh. It is possible to formulate an operation plan that takes into account the energy consumption characteristics of the heat source equipment. Thereby, according to this Embodiment 1, the complicated energy consumption characteristic which fluctuates according to the amount of waste heat water usage of waste heat utilization heat source equipment is considered with respect to all heat source equipment including heat source equipment which uses waste heat. It is possible to make an operation plan for the heat source equipment placed in Therefore, all the heat source equipment including the heat source equipment that uses the exhaust heat can be operated with high efficiency, and energy saving and CO ₂ emission reduction can be realized. For example, if the amount of exhaust heat in the heat source plant is small and the efficiency deteriorates due to the use of exhaust heat-utilizing heat source equipment, additional efficient electric equipment is started up or operated alone. This makes it possible to create an operation plan that reduces energy consumption. Further, when there are a plurality of exhaust heat utilizing heat source facilities and all of them do not have a sufficient amount of exhaust heat, the amount of exhaust heat to be distributed to each heat source facility can be precisely determined.
