  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram of a power supply / demand management (power supply / demand management) system according to a first embodiment of the present invention.

  As shown in FIG. 1, the power supply and demand management system grasps the amount of electricity in use on the recipient system (electric power user) 200 on the side receiving the power supply and the recipient system side, and controls the total amount of power used. The power monitoring system 100 includes a monitoring network 400 for exchanging data and control information between the power monitoring system 100 and the recipient system 200. Both the power monitoring system 100 and the recipient system 200 are provided with a server, and the monitoring network 400 is composed of an Internet line type LAN. The electric power generation includes a power plant 300 and a private power generation facility 230. The power line 350 is a line that supplies power from the power plant 300 to the recipient system 200.

  FIG. 2 is a block diagram showing the monitoring control relationship. As shown in FIG. 2, the power monitoring system 100 includes a demand monitoring control center 110, a regional receipt management center 120, and a specific recipient management center 130. Usually, the regional receipt management center 120 assumes that the server system installed at the substation functions as a management center, and the specific recipient management center 130 performs individual management as a large recipient or a power suppression control target. The facilities (equipment where many people gather, such as hospitals and theaters) and equipment are configured as management control targets. The regional receipt management center 120 and the specific recipient management center 130 share demander information belonging to the area managed by the regional receipt management center 120, and control whether the power demand is controlled in the regional receipt management center 120 or demand monitoring control. An information network configuration is used for information sharing and monitoring and management of total power demand in a structure that adjusts whether to optimize by controlling with the center 110. The demand monitoring control center 110, the regional receipt management center 120, and the specific recipient management center 130 are each composed of a monitoring server.

  The beneficiary system 200 includes a household power monitoring control device 210 and a centralized power monitoring control device 220 for large recipients. The recipient who owns the private power generation device 230 is also included in the constituent members. Both the household power monitoring control device 2 10 and the centralized power monitoring control device 220 control the electric device 250. The electric device 250 is equipped with a device capable of communicating with the Internet address of Ipv6 and the power monitoring control devices 210 and 220.

  The power monitoring control devices 210 and 220 are composed of power management meters 211 and 221 that measure the amount of electricity used under them, and control devices 212 and 222 that manage power consumption. The control devices 212 and 222 constitute a server function for performing communication (energy saving command) between a display device (comprising a display, a warning lamp, and an alarm notification device) that notifies the operator of energy saving control and the electric device 250. . The electric device 250 can control the power usage conditions (for example, in the case of an air conditioner, the temperature setting value can be self-controlled by an instruction from the power monitoring control devices 210 and 220) and the power monitoring control devices 210 and 220. Based on the alarm display, it can be divided into electrical devices that are handled manually.

  In addition, since the control device 222 is for a large / special recipient, it has a configuration for setting a protocol and an execution sequence (in which order the target devices are adjusted for energy saving) for energy saving operation, and power monitoring for ordinary households. Different from the control device 210, control is performed (usually, it is executed via the facility centralized monitoring facility 600). Whether in-facility communication of the recipient system 200 is performed via a power line or a separate Internet communication line is selected depending on the environment of the facility / house.

  The monitoring network 400 is configured to be connected using an Internet line such as a wireless LAN (Local Area Network) or an FTTH (Fiber to the Home) line. The power monitoring station 500 manages and manages the power supply amount of the power plant 300 and the supply management amount from other affiliated power companies, etc., and refers to a place that controls actual demand monitoring and power supply adjustment. The power monitoring system 100 is configured to receive the current power status from the power monitoring station 500 (the report from the receiver system 200 does not become the amount of supplied power due to electric leakage during transmission, temporary electricity use, consumption, etc.) .

(Description of operation)
The power monitoring system 100 in FIG. 1 serves as a monitoring server of the demand monitoring control center 110 for power supply and demand management, information on the operating status of the power plant 300, actual power consumption, etc., and the actual power supply status via the power monitoring plant 500. Receives the degree of surplus supply as management information for the energy-saving system. These operating statuses and the power consumption statuses reported from the regional receipt management center 120 and the specific recipient management center 130 are used for threshold control for energy saving management as the demand monitoring control center 110.

  Predetermined range width within the maximum power supply power amount of the power plant 300, etc. (the monitoring power amount for energy saving activation as the demand monitoring control center 110 is managed as a certain width: threshold value 1 (the actual value) to the threshold value 2 (upper limit value)) through the regional receiving management center 120 and the specific recipient management center 130, the power usage status of the recipient system 200, which is an energy saving management target, is monitored and controlled.

  As a management method, in order to make a control request from the power monitoring system 100, management divisions are provided (first division, second division), and attributes are classified into general and large / specific.

  The difference between the first and second, general, large / specific is to apply and manage the social and public impacts, the amount of power usage, the power transmission path, etc. as an adjunct in the order of energy conservation cooperation requests. Normally, the application order of energy saving is to determine and manage the power consumption in the area. The regional receiving management center 120 sets the power supply range as a management area for each substation, etc. It is divided into the first and the second, the first is the user who requests the energy saving request first, the second is the energy usage of the first class user that cannot be adjusted (suppressed) to the energy saving target range In the case of a state, a two-step method is adopted in which the target is further expanded to be a supply and demand person who requests energy saving. In the specific recipient management center 130 (two-stage division management is performed in the same manner as the regional receipt management center 120), the recipient system 200 for which power management is performed separately from the adjustment management in the regional receipt management center 120 is registered. Adjust supply and demand. In order to activate energy saving from the power monitoring system 100, an energy saving request is activated with the priority of the regional reception management center 120 → the specific recipient management center 130.

  The standard for registering the recipient system 200 in the regional receipt management center 120 and the specific recipient management center 130 is performed by the operation of the service system operator. The demand monitoring control center 110 comprehensively adjusts the start and release of energy saving requests to each regional receipt management center 120 and specific recipient management center 130. To that end, if it is judged that the local supply management center 120 that is in the process of energy conservation is in short supply and demand, even the regional reception management center 120 and the specific recipient management center 130 that are operating within the energy conservation threshold request cooperation. By doing so, the overall power shortage will be adjusted. This request target is a plurality of regions of the regional reception management center 120 and large specific recipients under the specific recipient management center 130 belonging to the region. In response to the request from the demand monitoring control center 110, the regional reception management center 120 or the specific recipient management center 130 requests the recipient system 200 to start / end the energy saving operation.

  The demand monitoring control center 110 takes an operation form in which the total power supplied is constantly received from the monitoring station 500 that monitors the power consumption of the electric power company. Upon receiving the request for energy saving mode management, the regional receiving management center 120 and the specified recipient management center 130 under the umbrella analyze the power usage status (those that exceed the energy saving management threshold in a specific region and large specified recipient) Start of energy saving for service category, which is subject to early request of local recipient 240 by energy saving mode, and target who has low impact on lifeline maintenance and production process in first category of large specific recipient 245 The instructions are given. Receiving system 200 that has received this instruction instructs electric appliance 250 to control power through control devices 212 and 222. In a normal case, when the threshold value is exceeded based on the energy saving threshold set in each regional receiving management center 120 and specific recipient managing center 130, a request for permission to apply energy saving is made to the demand monitoring control center 110. As a result of the request, energy saving adjustment is entered when the energy saving execution instruction comes (this is because the adjustment based on comprehensive judgment such as when there is a surplus in the amount of power supply as a whole is necessary, so the regional receipt management center 120, specific recipient management The center 130 does not give instructions to save energy.

  The electric device 250 is a lighting device or an air conditioner, but both have an IPv6 address, and an instruction for energy saving is transmitted to the automatic control device incorporated in the device via the interface. The The energy saving method is converted and controlled for each device according to the conditions set by the user / administrator of the device (for example, changing the indoor temperature setting value, turning off the lighting fixture, suppressing heating power, etc.). The result of entering the condition is reported to the regional receipt management center 120 and the specific recipient management center 130 (whether it is unmanageable or within the energy saving management range and the amount of electricity used). As a result, if the energy saving threshold value managed by the regional receipt management center 120 and the specific recipient management center 130 is reached, the operation is continued until the demand monitoring control center 110 cancels the energy saving as it is. When the state where energy saving cannot be achieved continues, energy saving is activated to the subordinate second subdivisions at the regional receipt management center 120 and the specific recipient management center 130. When the regional receipt management center 120 and the specific recipient management center 130 receive these energy saving suppression results and it is determined that it is necessary to expand the scope of further energy saving, the demand monitoring control center 110 is notified of the power deterrence impossible report. Then, the other area receiving management center 120 and the specific recipient managing center 130 are requested for an energy saving request adjustment instruction. If the situation is not improved even in this situation, the demand monitoring control center 110 performs total demand control by making an operation request to the consumer having the private power generation facility 230.

  The household power monitoring control device (server) 210 shown in FIG. 1 is a control device for energy-saving control for an energy-saving electrical device 250 based on a power management meter 211 corresponding to a conventional electric meter and its meter value (current value and integrated power amount). At 212. The control device 212 performs control based on the registered instruction information for each device via the distribution board 241 in order to instruct the electric device 250 in the energy saving mode. The registration of the instruction information is set for each device (IPv6 compatible) from the operation panel of the control device 212. For example, in the case of an air conditioner, either a relative instruction to increase the temperature by 3 degrees from the current value or an absolute instruction value to be set to 27 degrees is registered. In the case of a washing machine, the automatic operation start time is reset, the start after one hour is designated, and the like. These designation information is operated by the value received from the control device 212 on the side of the device having IPv6 (the interface and control protocol for control between the control device 212 and the electric device 250 are defined when the system is introduced). Usually, the specification of the control device 212 is presented as a standard). The form presented by the control device 212 is an Internet specification using IPv6 and a format standard for control information.

  The centralized power monitoring and control device (server) 220 is a server for large and specific recipients, and the power management meter 221 takes a form that works in conjunction with the centralized monitoring device (control device) 222. As a function of the centralized monitoring device 222, in addition to the function of the control device 212, an interface to the private power generation facility 230 is provided, so that a method of generating power for energy-saving alternative power supply is also possible.

  FIG. 3 is a diagram showing a flow of energy saving monitoring of the recipient system 200. When the household power monitoring control device 210 and the centralized power monitoring control device 220 receive an energy saving start instruction from the power monitoring system 100, the energy saving monitoring instruction a is received from the energy saving monitoring application control state S1, and the process proceeds to energy saving monitoring S2. . When the power value enters the range of energy saving control in the state of energy saving monitoring S2, energy saving monitoring is started / monitored b, and between threshold value monitoring state S3 (threshold value 1 (lower limit value) to threshold value 2 (upper limit value)) To monitor whether it is in use. In this state, the energy saving display c is performed on the display devices of the control devices 212 and 222 (the monitoring person blinks the energy saving lamp and the display is displayed), and the energy saving (suppression) display notification S4 is performed simultaneously with the energy saving. The application state S5 of the electricity charge during the energy saving operation is entered to charge the charge c. When returning from the threshold value monitoring state S3 to the energy-saving monitoring state S2, the energy-saving charge cancellation j is performed, and the process proceeds to the normal charge state S7.

  When the power usage state d exceeding the energy saving monitoring threshold 2 (upper limit value) is entered, the power suppression instruction state S6 is entered, and an instruction is issued to the electric device 250 to operate under the conditions set for the electric device 250 to be saved. . In addition, while the threshold value 2 is exceeded, the application of energy-saving billing is stopped e.

  If the value does not return within the threshold value, a non-suppression report i is sent to the power monitoring system 100. Further, in the power over state, when the condition setting for avoiding the over state is performed in the private power generation, the private power generation operation instruction g is performed and the process proceeds to the private power generation operation state S8. At the same time, private power generation operation charging application 1 is started. In order to perform threshold control among the private power generation operation state S8, the power suppression instruction state S6, and the threshold value monitoring mode S3, the state of communication between each other is repeated. The required power supply amount obtained is adjusted. In addition, the device 230 having a contract and operating conditions when power can be reversely supplied (sold) by private power generation supplies private power supply in response to an operation request h from the power monitoring system 100.

  FIG. 4 is a diagram showing the relationship between the household power monitoring control server and the control target device. The server of the home power monitoring control device 210 is connected to the power monitoring system 100 (server) by forming a monitoring network with the LAN line 400. When the current power consumption value is reported through this line, or when the server side of the power monitoring system 100 comprehensively monitors the power consumption demand and reaches the monitoring level where power over is predicted, the home power monitoring control device 210 Give instructions to take energy-saving measures. In the server of the household power monitoring and control device 210, an instruction to save energy according to the set condition is given to the electric devices 250-1 (device A) and 250-2 (device B) (control information is transmitted to the IP address via the power line and the communication line) When the target device is not a power line but other line means, the control device 212 can be equipped with the device and function of the communication interface). Since the electric device 250-4 (device D) does not have an automatic control function, the energy saving operation is manually performed in response to the energy saving notification (alarm sound and alarm lamp blinking, wording displayed on the display 213, etc.) of the control device 212.

  In the case of the centralized power monitoring control device (server) 220 of FIG. 5, when the operation control of the electrical equipment 250 and the power generation equipment 230 is performed by a method in which the facility centralized management monitoring equipment 600 is interposed between the electrical equipment 250, Control instructions to the electric device 250 and the power generation facility 230 can be interfaced via the facility centralized management monitoring facility 600. This enables adjustment with the facility operation management side.

  Electric power supply and demand control will result in a supply stop (power outage) state at a supply management facility such as a substation if the amount of power supply is exceeded even momentarily. Therefore, the demand monitoring control center 110, the regional reception management center 120, and the specified receiver management center The threshold setting of the power monitoring adjustment of 130 is performed with a sufficient margin (eg sudden demand during energy-saving control, delay time of transition, etc.), and measures such as warnings are also performed at the threshold level 1 to facilitate operation management. It is desirable to operate as an efficient energy saving system. The demand management control server 110 monitors and manages the regional receipt management center 120 and the specific recipient management center 130.

  The power consumption value that is the standard for monitoring management is that the power status a1 is received from the power monitoring station 500 (the power generation capacity of the power plant 300 and the current power supply amount), and the local power management b1 and large-scale power supplier power management Supplied with power consumption status reports for users who can manage energy conservation as c1 (past statistics, seasonal fluctuations, temperature, economic activity, etc., transmission route and local reception management center 120, specific recipient management (Supply and demand adjustment whether energy saving is activated at the center 130). When it is determined that an electric power overage is predicted to occur even in this adjustment, an instruction is given to an area where energy conservation control is performed or a specific receiver server through the route of the responsible area power management b1 and the large-scale demander power management c1.

  The servers of the regional reception management center 120 and the specific recipient management center 130 that have received the energy saving instruction instruct the recipient system 200 to start energy saving operation and receive the result of adjustment of the energy saving adjustment power capacity (threshold value 2 or less) in the region. Report to the management center 120 and the specific recipient management center 130. In the regional receipt management center 120 and the specific recipient management center 130, when the energy-saving target first classifier determines that the energy-saving power consumption does not fit, the second classifier is instructed to perform energy-saving management. Then, the adjustment result is reported to the regional receipt management center 120 and the specific recipient management center 130.

  The regional receipt management center 120 and the specific recipient management center 130 report their reporting status to the demand monitoring control center 110. If it is determined that the demand monitoring control center 110 does not fall within the predetermined power demand in this report, the target regional receiving management center 120 and the specific receiver managing center 130 are added. In addition, a request is received through the specific receiver management center 130 for the receivers belonging to the specific receiver management center 130 having the power generation facility 230 to enter into the request / preparation for power generation.

  The demand monitoring control center 110 manages the energy-saving operation status of the power generation capacity of the demand monitoring control center 110 (in-house power generation of the power generation facility 230 in a state below the threshold 1 set in the demand monitoring control center 110). Instruct to cancel energy-saving operation step by step.

  The stage of energy saving is a demand for power from the demand monitoring control center 110 and the regional reception management center 120. When the threshold value is 1, an energy saving request is made to a specific regional reception management center 120 / specific recipient management center 130 for a standby state.

  This stage has the role of a buffer to enter into comprehensive energy saving. The execution of energy saving is triggered by the threshold 1 and from the energy saving judgment request, the first category of the regional receipt management center 120 → the second category → the expansion of the application area to other regional receipt management centers 120 → the first of the specific recipient management center 130 It is performed in the order of one division → second division → expansion to other specific recipient management center 130 → in-house power generation operation. The energy saving cancellation is performed in the reverse sequence.

  When the operation related to the monitoring control in FIG. 3 is shown by the management of the power supply and demand control information, the demand monitoring control center 110 performs the monitoring adjustment in Tables 1 and 2 as follows.

地域受給管理センター１２０、特定受給者管理センター１３０、電力監視所５００から報告される情報に基づき地域1（閾値1、閾値２、現在電力値、省エネ発動の有無）、地域２のように全地域の電力状況を監視するその中で閾値２を越える地域が生じた場合（当該地域受給管理センター１２０から省エネ発動要請もあがってくる）その地域に給電している給電所の供給能力を確認すると共に、その給電所が関係する地域の需給状況から、省エネ発動を行なうか判断する。

All regions such as region 1 (threshold 1, threshold 2, current power value, presence / absence of energy-saving activation), region 2 based on information reported from region receiving management center 120, specific recipient management center 130, power monitoring station 500 When an area exceeding the threshold value 2 occurs in the monitoring of the power status of the area (request for energy conservation activation from the area reception management center 120 is also raised) and confirming the supply capacity of the power station supplying power to the area Then, it is determined whether or not to perform energy saving based on the supply and demand situation in the area where the power station is related.

  In some cases, the power supply is controlled within the range by making an energy conservation activation request to the same power supply area. Also determine the status of large customers at the specified beneficiary management center (considering the area to which the facility belongs, the proportion of power consumption to the power substations, etc. Make adjustments to combine requests.

  The adjustment sequence and activation requirements performed by the demand monitoring and control center 110 are set according to conventional power consumption trends and the like and requirements for individual activation conditions with large customers (set through individual confirmation through contracts, etc.).

  The regional receipt management center 120 manages the customers in Table 3, but when the request for energy saving is made from the demand monitoring control center 110, the recipient system 200 makes an energy saving request to the autonomous recipient system 200, and the recipient system 200 saves energy. Adjustment is performed. The specific recipient management center 130 performs adjustment management in Table 4, but the information on the power supply substations in Tables 3 and 4 is also reflected in Table 2.

地域受給管理センター１２０、特定受給者管理センター１３０の区分２への省エネ要請も顧客との省エネ要件（設定閾値、省エネシーケンス）を確認調整を経て設定される。この設定された要件により需要監視コントロールセンター１１０と連動する形で電力調整がなされる。

The energy saving request to the category 2 of the regional receipt management center 120 and the specific recipient management center 130 is also set after confirming and adjusting the energy saving requirements (setting threshold value, energy saving sequence) with the customer. The power adjustment is performed in conjunction with the demand monitoring control center 110 according to the set requirement.
