[1. First Embodiment]
The energy management system 1 of this embodiment manages the electric power sent from the outside in the community 2 by the whole EMS (energy management system) 3, and distributes it to the consumers in the community 2. Each consumer manages and uses the distributed power by the EMS that each consumer has.

The community 2 in the present embodiment is a group that collectively receives power from the outside, and a plurality of consumers in the community 2 share and share the power. Examples of the community 2 and consumers include the following (1) and (2).
(1) When a community is formed by a plurality of commercial facilities, buildings, or apartment houses, the consumers are commercial facilities, buildings, and apartment houses that form the community.
(2) When a community is formed by one commercial facility, building, or apartment house, the consumer is a commercial facility that forms the community, a tenant in the building, or a house in the apartment house.
In the following description of the present embodiment, a community 2 is formed by one building, and a tenant 4 occupying the building is a consumer. The EMS of the building is the entire EMS3, and the EMS of the tenant 4 is the tenant EMS41.

  The entire building EMS 3 makes a power consumption reduction request for reducing power consumption in the tenant 4 to the tenant EMS 41 as necessary. The power consumption reduction request is made when the power consumption of the entire building 2 is reduced by a direct power saving request from a power supply company that supplies power to the building 2, and the tenant in the building 2 from the entire EMS3 4 is performed. Moreover, it can be used not only to directly request power saving but also to suppress power consumption in a building during so-called demand response.

  The tenant EMS 41 sets the amount of power consumption in the tenant 4 according to the power consumption reduction amount from the entire EMS 3. Then, the use / nonuse of the load in the tenant 4, the use time, and the use frequency are determined according to the amount of power consumption.

  The power usage in the tenant 4 is totaled by the tenant EMS 41, and the total result is output to the entire EMS 3. In the overall EMS 3, the incentive obtained according to the power saving contribution degree of each tenant and the demand response based on the total result is disclosed. By visualizing the amount of tenant reductions, the degree of contribution of each tenant is appealed and disclosed to bring the reduction target closer to the achievement of the reduction target and guarantee mutual collective responsibility.

[1-1. Constitution]
FIG. 1 shows a schematic diagram of an energy management system 1 according to the first embodiment of the present invention. As shown in FIG. 1, the energy management system 1 of the present embodiment includes an entire EMS 3 and a tenant EMS 41.

  The entire EMS 3 distributes the electric power sent to the community 2 from the outside to the tenant 4 in the community 2 and the shared part. In addition, a power consumption reduction request for reducing power consumption in the tenant 4 is made to the tenant EMS 41. Furthermore, the total result of the power consumption in the tenant EMS 41 is collected. Calculate the power saving contribution and incentive from the collected results. The entire EMS 3 includes a mode instruction unit 31, a mode storage unit 32, and a result data collection unit 33.

  The mode instruction unit 31 instructs the power consumption reduction amount for the tenant EMS 41. The power consumption reduction amounts are “normal mode”, “DR mode (LEVEL 1)”, “DR mode (LEVEL 2)”, “DR mode (LEVEL 3)”, and “emergency (BCP) mode” according to the reduction amount of power consumption. Is represented. In the “normal mode”, when it is not necessary to reduce power consumption, the levels of “DR mode (LEVEL 1)”, “DR mode (LEVEL 2)”, and “DR mode (LEVEL 3)” depend on the degree of power tightness. This level is in accordance with the amount of reduction required by the power supply company. As the “DR mode” level increases, the power consumption reduction amount for the tenant EMS 41 increases, and as the requested reduction amount increases, a higher level “DR mode” is set. “Emergency (BCP) mode” is a mode in which operation by the emergency power supply device 5 provided in the building 2 is performed when power is not received from outside due to a disaster or the like. The level of the DR mode is not limited to the above three types, and can be freely defined, for example, only one level or four levels or more. Also, a plurality of types and levels can be defined in the emergency (DR) mode.

  For example, the “normal mode” indicating the power consumption reduction amount is a mode in which the power consumption reduction amount is 0%. “DR mode (LEVEL 1)” is a mode in which the power consumption reduction amount is 5%, and “DR mode (LEVEL 2)” is a mode in which the power consumption reduction amount is 10%, and “DR mode (LEVEL 3)”. "Is a mode in which the power consumption reduction amount indicates 15%. “Emergency (BCP) mode” is a mode when power is not supplied to the community 2 such as when power supplied to the entire EMS is cut off.

  In the “emergency mode”, a private power generation device 5 capable of generating in advance the amount of power necessary for the tenant 4 in the building 2 to continue the business is installed, and based on the power generated by the private power generation device 5 Operate community 2. The “emergency mode” is a mode in which emergency lights, guide lights, sprinklers, fire alarm equipment, etc. are operated as disaster prevention equipment. In addition, the power generation amount of the private power generation device 5 is increased, the amount of power that the business can continue is secured, and the “business continuity planning (BCP) mode” (hereinafter referred to as BCP mode) is used. It can also be. The “BCP mode” is a mode in which the lighting equipment is operated intermittently, and the telephone, FAX, server, and minimum elevator are used for communication means. In the “BCP mode”, in order to reduce the power consumption of elevators and escalators and other elevators, the elevators are operated at a low speed, operated at a low speed, or the number of operating units is limited, or the number of stops is limited. You may do it.

  The mode storage unit 32 stores the power consumption reduction amount and each mode corresponding to the power consumption reduction amount in association with each other.

  The power consumption reduction amount in the mode instruction unit 31 is manually selected by the user who manages the entire EMS 3 using the input unit 6 that is an input interface. Alternatively, it can be configured to be selectable by an instruction from outside the community.

  The performance data collection unit 33 collects the total results of the power usage in the tenant EMS 41. The power saving contribution or incentive is calculated from the collected results. The performance data collection unit outputs the calculated power saving contribution degree or incentive to the Web Server 7.

  The Web Server 7 is configured to be accessible from the outside by the portable terminal 9, the PC 10, and the EMS 11 via the Internet 8. By accessing the Web Server 7 from the portable terminal 9, the PC 10, and the EMS 11, the power saving contribution degree or the incentive can be referred to.

  In the tenant 4, the electric power distributed by the entire EMS 3 is managed by the tenant EMS 41, and the elevator 42, the lighting fixture 43, and the air conditioner 44, which are load facilities, are operated. When there is a power consumption reduction instruction from the entire EMS 3, the tenant EMS 41 sets the amount of power used in the tenant 4 according to the mode indicating the power consumption reduction amount. The tenant EMS 41 includes a function generator 45.

  The function generator 45 periodically changes operating conditions of the elevators 42, the lighting fixtures 43, and the air conditioners 44, which are load facilities in the tenant 4, according to the mode indicating the power consumption reduction amount. Periodic operating conditions are expressed as periodic operating parameters. The function generation unit 45 sets at least one of the operation cycle, the maximum load operation time, the minimum load operation time, the maximum load level, and the minimum load level among the periodic operation parameters, and thereby uses power in the tenant. Change the amount.

[1-2. Action]
(Cyclic operation parameter setting)
A method for setting the periodic operation parameters of the present embodiment will be described with reference to FIG. FIG. 2 is a graph showing periodic operation parameters. The periodic operation parameter indicates the load level in the operation cycle per hour, with the load level on the vertical axis and time on the horizontal axis.

  The operation cycle is a time that can be arbitrarily set by the tenant user. When electricity charges are calculated in units of 30 minutes, it can be an integer multiple of 30 minutes, such as 30 minutes, 60 minutes, 90 minutes, etc., or 3 minutes, 5 minutes, 10 minutes It can also be made into 30 minutes or less. In the operation cycle, the operation time at the maximum load and the operation time at the minimum load are combined to form one operation cycle.

  The maximum load level is set to a value equal to or less than the total load when the elevators 42, the lighting fixtures 43, and the air conditioners 44 in the tenant 4 are operated with ratings. The minimum load level is a value that is equal to or higher than the load when the elevators 42, lighting fixtures 43, and air conditioners 44 in the tenant are operated under the lower limit constraint.

  The maximum load level and the minimum load level can be set to arbitrary values. For example, the maximum load level is set to the load level when the elevator 42, the luminaire 43, and the air conditioner 44 are operated at the rated value. In the load operation time, the elevator 42, the lighting fixture 43, and the air conditioner 44 can be operated with ratings. As a result, even when a reduction in power consumption is requested, it is possible to operate at an efficient rating for a certain period of time. In addition, by setting the minimum load level to the load level when the elevator 42, the lighting fixture 43, and the air conditioner 44 are operated with the lower limit constraint, the elevator 42, the lighting fixture 43, and the air conditioning unit 44 can be used in the minimum load operation time. It is possible to supply the minimum electric power necessary for operation under the lower limit constraint. Note that the above minimum load level is defined as a device stop state and can be operated.

  Next, the time for operating at the maximum load and the time for operating at the minimum load in the operation cycle of the periodic operation parameter are set. As a result, the amount of power used in the operation cycle is set. In the operation cycle, when the amount of power consumption reduction is small, the time to operate at the maximum load is increased, and when the amount of power consumption reduction is large, the power consumption is adjusted by increasing the proportion of time to operate at the minimum load. To do.

  Based on the cyclic operation parameters set in this way, the elevator 42, the lighting fixture 43, and the air conditioner 44 in the tenant 4 are periodically operated, so that the power consumption in the operation cycle is instructed from the entire EMS 3 to reduce the power consumption. It becomes possible to keep in.

[1-3. effect]
In the energy management system 1 of the present embodiment as described above, the electric power transmitted from the outside to the community 4 is managed by the entire EMS 3 (energy management system) and distributed to the consumers in the community 2. Each consumer manages and uses the distributed power by the tenant EMS 41 possessed by each consumer.

[2. Second Embodiment]
[2-1. Constitution]
The energy management system 1 of the present embodiment performs control for adjusting the cycle or phase of the load level of the elevator 42, the lighting fixture 43, and the air conditioner 44 in the tenant EMS 41.

  FIG. 3 shows a schematic diagram of the tenant 4 according to the present embodiment. As shown in FIG. 3, the tenant 4 of this embodiment includes an elevator 42, a lighting fixture 43, and an air conditioner 44 as load facilities. The tenant EMS 41 includes a function generation unit 45, a factor-specific adjustment unit 46, an individual parameter storage unit 47, an in-tenant cooperative control unit 48, an air conditioning control unit 42a, a dimming control unit 43a, and an elevator control unit 44a.

  In the function generation part 45, a periodic operation parameter is set based on the power consumption reduction request from the whole EMS3. The factor-specific adjustment unit 46 performs adjustment based on various factors when setting the periodic operation parameters. Factors include tenant type, season, number of people, event, day of the week, and time zone. For example, in a tenant that provides lunch, during the summer season from 11:00 to 14:00, adjustment is performed to prioritize the air conditioning operation when setting the periodic operation parameters. In addition, the tenant 4 hitting the sun is set so that the power consumption during that time can be increased. The adjustment based on this factor is stored in the individual parameter storage unit 47 as an individual parameter.

  The in-tenant cooperative control unit 48 adjusts the cycle and phase of the operation cycle parameters of the elevator 42, the luminaire 43, and the air conditioner 44 within the range of the periodic operation parameters set by the function generation unit 45, so Perform cooperative control.

  The air conditioning control unit 42a, the dimming control unit 43a, and the elevator control unit 44a control the elevator 42, the lighting fixture 43, and the air conditioner 44 according to the load level whose period and phase are adjusted by the in-tenant cooperative control unit 48. Do.

[2-2. Action]
(Cyclic operation parameter setting)
A method for setting the periodic operation parameters of the present embodiment will be described with reference to FIGS. FIG. 4 is a graph showing periodic operation parameters of the air conditioner 44 and the lighting equipment 43. As shown in FIG. 4, the periodic operation parameters of the air conditioner 44 are set by shifting the period and phase from the periodic operation parameters of the lighting equipment 43.

  In addition, the periodic operation parameters of the air conditioner 44 and the lighting equipment 43 can be freely set as long as they are within the range of the periodic operation parameters set by the function generator 45. FIG. 5 is a diagram illustrating the relationship between the periodic operation parameters set by the function generator 45 and the periodic operation parameters of the air conditioner 44 and the lighting equipment 43.

As shown in FIG. 5, when the maximum load level is A as the periodic operation parameter set by the function generator 45, the relationship between the load level of the air conditioner 44 and the load level of the lighting equipment A2 is as follows. Equation (1) is obtained.
A = A1 + A2 (1)
That is, the maximum load level of the periodic operation parameter set by the function generator 45 is the sum of the maximum load level of the air conditioner 44 and the maximum load level of the lighting equipment.

Further, when the minimum load level of the periodic operation parameter set by the function generator 45 is B, the relationship between the load level of the air conditioner 44 and the load level of the lighting equipment B2 is expressed by the following equation (2). Become.
B = B1 + B2 (2)
In Expression (2), with respect to the maximum load level of the periodic operation parameter set by the function generator 45, the load level of the air conditioner 44 is B1, and the load level of the lighting equipment is B2. When the load level of the air conditioner 44 is B1 and the load level of the lighting equipment is B2, B1 is a value smaller than B2, so the power consumed by the air conditioner 44 is smaller than the power consumed by the lighting fixture 43. Become.

In the case where the minimum load level of the periodic operation parameter is B, when it is desired to increase the power consumed by the air conditioner 44, the load level B3 of the air conditioner 44 is set higher than the load level B1 of the air conditioner 44. In this case, when the minimum load level of the periodic operation parameter set by the function generator 45 is B, the relationship between the load level of the air conditioner 44 and B4 and the load level of the lighting equipment is represented by the following formula (3 )
B = B3 + B4 (3)
In Formula (3), with respect to the maximum load level of the periodic operation parameter set by the function generator 45, the load level of the air conditioner 44 is set to B3 larger than the load level B1, and the load level of the lighting equipment 43 is set to B4 smaller than B2. . When the load level of the air conditioner 44 is B3 and the load level of the lighting equipment 43 is B4, the power consumed by the air conditioner 44 is greater than the power consumed by the lighting fixture 43 because B3 is greater than B4. growing.

[2-3. effect]
In the present embodiment as described above, cooperative control can be performed in the load facility in the tenant. That is, the power consumed by the air conditioner 44 and the lighting fixture 43 can be set according to the periodic operation parameter set by the function generator 45. Thereby, important load equipment can be operated preferentially. For example, when the temperature rise is expected in summer, the air conditioner 44 can be preferentially operated, while the elevator 42 and dimming power can be reduced. Similarly, when giving priority to the operation of the elevator 42, the power consumption of the air conditioner 44 and the lighting equipment is reduced.

  In the present embodiment, the load levels of the air conditioner 44 and the lighting fixture 43 are set according to the periodic operation parameters set by the function generator 45, but other load facilities can be combined.

  For example, as shown in FIG. 6, the air conditioner 44 and the elevator 42 can be cooperatively controlled. At this time, the power consumption in the load facility may be set in accordance with the characteristics of the load facility to be combined. In FIG. 6, the air conditioner 44 and the elevator 42 are combined. However, when the elevator 42 is not used, the power of the air conditioner 44 is distributed. On the other hand, at the time T <b> 1 when the elevator 42 is operated, the elevator 42 is operated at a rating and the load level at the air conditioner 44 is reduced. As a result, the power consumption can be suppressed within the periodic operation parameters set by the function generator 45 while the elevator 42 is operated efficiently.

[3. Third Embodiment]
[3-1. Constitution]
The energy management system 1 of the present embodiment controls the air conditioner 44 that is a load facility in the tenant based on the thermal sensation index (PMV) based on the periodic operation parameters set in the tenant EMS 41.

  FIG. 7 shows a schematic diagram of a tenant according to the present embodiment. As shown in FIG. 7, the tenant EMS 41 of the present embodiment includes a function generation unit 45, a PMV control unit 49, and an air conditioning control unit 44a.

  The PMV control unit 49 sets a PMV target value, which is a comfort index in the tenant room, to the air conditioning control unit 44a based on room temperature, humidity, radiation temperature, airflow, activity amount, and clothing amount at each time. To output the room temperature set value.

  The air conditioning control unit 44a controls the air conditioner 44 installed in the tenant room based on the room temperature setting value from the PMV control unit 49, and the ON / OFF state of the external air conditioner, the air conditioner, the fan coil, etc. And the operating condition of the cooling water pump are optimally adjusted.

[3-2. Action]
In the present embodiment, a control instruction is output to the air conditioning control unit 44a so as to achieve the PMV value target value only during the maximum load operation time of the operation cycle of the periodic operation parameter set in the tenant EMS.

  On the other hand, the air conditioner 44 is operated so as not to exceed the minimum load level during the minimum load operation time of the operation cycle of the periodic operation parameter.

[3-3. effect]
In the present embodiment as described above, the air conditioner 44 is operated so as to achieve the PMV value target value during the maximum load operation time in the operation cycle of the periodic operation parameter. Thereby, even when it is necessary to reduce power consumption, the PMV value target value can be achieved in the tenant room in a certain cycle.

  In general, since the room temperature is warmed / cooled in the periodic operation of the air conditioner 44, the room temperature does not change suddenly after the air conditioner 44 is stopped due to the housing heat storage effect. Therefore, even when the operation cycle of the periodic operation parameter is switched from the maximum load operation to the minimum load operation, the PMV value of the tenant room does not immediately deviate greatly from the target value. In particular, when the operation cycle is not long, the PMV value of the tenant room can be set as the target value by the maximum load operation before the PMV value greatly deviates from the target value.

FIG. 9 is a graph showing periodic operation parameters of the tenant EMS1 and the tenant EMS2. As shown in FIG. 9, the periodic operation parameters of the tenant EMS1 are set by shifting the period and phase from the periodic operation parameters of the tenant EMS2.

[4-3. effect]
In the present embodiment as described above, cooperative control between tenants can be performed. That is, the phase and cycle of the periodic operation parameter of the tenant EMS1 and the periodic operation parameter of the tenant EMS2 are shifted.

  As a result, while the load level of the tenant 1 is increased, the load level in the community can be suppressed by decreasing the load level of the tenant 2.

  In addition, it is possible to assign tenant priorities in the community, increase the load level of tenants with high priority, and decrease the load level of tenants with low priority. For example, it is possible to reduce the tenant load level on a regular holiday and increase the tenant load level on business days. As a result, it is possible to reduce power consumption in the community while increasing the load level of a tenant that requires power.

  In the present embodiment, the inter-tenant cooperation control unit 50 is provided in the tenant EMS of each tenant in the community, but may be provided in the entire EMS 3 as illustrated in FIG. By providing the inter-tenant cooperative control unit 50 in the entire EMS 3, it is possible to perform inter-tenant cooperative control by a command from the entire EMS 3 without providing the inter-tenant cooperative control unit 50 in the tenant EMS of each tenant. It becomes.
