Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric power supplier (generally, an electric power company) and an electric power user (generally, an electric power customer) supplying electric power according to an electric power supply contract. In a system that is supposed to receive power supply (= power supply system), this is performed for the purpose of increasing the utilization rate of power supply facilities on the power supplier side or improving the reliability of power supply [supply power / Supplying equipment load factor etc.].

[0002]

2. Description of the Related Art The power supply leveling method currently employed by Japanese power suppliers defines an incentive target menu for power users, that is, a. Define a specific period (summer or night) / b. Specific power use equipment (heat storage equipment, etc.) was defined, and incentives (special unit price, discount / surcharge rate, remuneration, penalty, etc.) for each menu were set. (The incentive was specified in a written document (the document that constitutes the contract), and the degree of incentive was a fixed and constant one displayed in printed characters. As a result, even if the method of incentive provision (time of incentive application and degree of incentive) is not appropriate, it takes time to find out,
Incentives could not be changed on the fly. )

In many cases, it is necessary to install a plurality of power metering devices (hereinafter referred to as “received power detail recording unit”) installed on the power user side in order to calculate a power rate. (Reason: In many cases, contracts are not made for a single power-using facility, but for specific facilities (for example, thermal storage facilities) that make up the power-using facility. There were multiple installation locations.)

[0004]

[Problems to be Solved by the Invention] In an economy-led society, a power supply system (a system including a power supply system on the power supplier side and a power use system on the power user side) is also positioned under the economic system. I have. The economy is driven by human psychology. Therefore, the tasks are:
The aim is to flexibly achieve "leveling of the supply power intended by the power supplier". Specifically, in the present specification, the power supplier side makes an action such that the interests of the power supplier side and the power user side coincide with each other. The expression "data" is automatically generated by a program preset on the power supplier side, and is transmitted to the power user side. In the case of [automatic mode], the power user automatically processes "electronic incentive data" transmitted according to a preset program and controls the power using equipment. In the case of [manual mode], the contents of the "electronic incentive data" are monitored and the power use equipment can be controlled by manual operation.
The problem to be solved subsequently is to have the transaction (power supply) statement corresponding to the system according to the invention clearly recorded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Outline of the system: In the present invention, a large system including facilities, organizations and ideas on the side of electric power suppliers (human psychology) and facilities, organizations and ideas on the side of electric power users (this system is referred to as the present invention) Then, "supply power leveling system"
Call. The leveling of the supply power is achieved in the above). This system is based on a completely new concept.

Hereinafter, the configuration of the system will be described with the meaning of terms used in the present invention and the operation of each unit. FIG. 1 shows a practical configuration of a supply power leveling system according to the present invention. Since the value of the system according to the present invention depends on the operation of the system, the explanation is given here to explain how to operate the system. However, the operation method described here is not a requirement of the present invention.

[0008] "Electronic incentive data" means the following "incentive data" in a form that can be processed by a computer.

The "incentive data" is data in which the following "incentive" can be understood one by one or in whole, and has a document format which can be written and read by a human.

In the present invention, the "incentive" means that the power supplier (1) presents the power user (2) to the power user corresponding to a physical quantity that the user wants to control by controlling the power user (2). This indicates the degree of incentive (the "degree" is expressed in a form that can be replaced with a numerical value that can be used for calculation) corresponding to each incentive menu for each application time zone on a one-to-one basis. Here, “physical quantity to be controlled” means, for example, peak power [kW], average power [k
W], received power amount [kWh], power amount per specified time (demand) [kWh], received reactive power amount [kvar ·
h], harmonic current [A] included in the received current, and the like.

The "power supplier side (1)" refers to all power generation and transformation facilities, transmission and distribution facilities, organizations and personnel, operations and activities, etc., under the control of the power suppliers. For large power companies,
The term "power supplier" was used instead of "power supplier" because facilities and ideas may differ between branches.

The "contract data (11)" and the "contract data (21)" are contract data relating to power reception and define power transaction conditions. Naturally, the contract data (11) held by the power supplier (1) and the contract data (21) held by the power user (2) have the same contents. The contract data dealt with in the present specification relates to the leveling of the supplied power and relates to an incentive that the power supplier (1) may change according to the situation. In the contract,
The outline of how the incentive is applied (what kind of incentive is in which situation, and the degree of change = range of change) must be shown. All such contract data are functions of or correspond to time and are replaced by numbers.

Here, the contractual treatment of the three incentive data defined in claim 2 will be described. “Incentive forecast data” is forecast data and becomes more accurate as time progresses. ("Incentive data confirmed"
Approach. This data is for reference only and is not used for calculating electricity rates. “Incentive confirmation data” is data for determining (promising) the degree of incentive.
If a contract is made to use this data, the electricity rate is calculated using this data. Should "urgent additional incentive data" be added to or replace "incentive confirmed data" already communicated due to urgent situation changes?

[0014] In any case, whether or not to use "emergency additional incentive data" depends on the contract. The “power supply facility (15)” refers to all facilities until the power of the power supplier (1) is delivered to the power user (2). (The transmission and distribution lines are not shown.)

The "power supply equipment data (16)" is a data which can be computer-processed with data relating to the power supply of the power supply equipment (15) from the past to the present. The contents include on-off signal of equipment, run-stop signal, meter reading, supply capacity, supply capacity, accident / failure information, accident rate, equipment operation / stop plan, precipitation, fuel market data, etc. Equivalent to.

The "program setting unit (12)" on the power supplier side (1) means that the organization of the power supplier side (1) collects the power supply equipment data (16) based on the contract data (11). Set a framework (logic) to automatically generate electronic incentive data from equipment data that changes every day, taking into account the business index, business index, management policy, etc., and convert it to software (create software) . Update the software (basic logic) and software as necessary according to the situation change. (This software is installed in the “incentive data generator (14)”.
In addition, this software uses the “incentive correction unit (1
3) The electronic incentive data can be corrected with the incentive correction data from "3)." )

The "incentive correction unit (13)"
Within the framework defined by the "program setting unit (12)", the human incentive is included in the electronic incentive data generated by the "incentive data generating unit (14)" according to the situation, according to the situation of the human being. This is where the correction operation is performed. (The output from the incentive correction unit is referred to as "incentive correction data.") In the correction operation, if the latest situation change is sudden and unexpected, the "incentive data generation" (14) generating "urgent additional incentive data". Here, “when the latest situation change is sudden and unexpected” means that when a major accident occurs in the power supply facility (15) on the power supplier side (1) and the power supply capacity suddenly decreases, social This corresponds to a case where a major incident occurs and television receivers throughout the country are expected to be turned on.

"Incentive data generator" (1
"4)" means that the "power supply equipment data (16)" is processed according to the program created by the "program setting unit (12)" to generate electronic incentive data. (If there is an incentive correction input from the “incentive correction unit (13)”, the generated electronic incentive data is corrected by that.)

The “power user side (2)” means power receiving equipment, load equipment, organization / personnel, operation /
Refers to all activities. The term "electricity user" was used instead of "electricity user" because responsibilities and authorities related to equipment were sometimes distributed to subordinate organizations. (Note) If the electric power company has an electric wholesaler who wholesales electricity,
The present invention can be applied to electric wholesalers.

"Electric power using equipment (25)" means all equipment that receives and uses (consumes) electric power supplied from the electric power supplier side (1). (The power receiving path is not shown.)

"Electric power usage facility data A (26)"
This is in a form that can be computer-processed with data on the power usage of the power usage facility (25) from the past to the present. The contents include the on-off signal of the equipment, operation-
Stop signals, meter readings, equipment capacity, equipment reserve, equipment availability, accident rates, equipment operation / stop plans, operation data, and the like. Data includes not only measured data but also processed data obtained by using statistical methods. here,
Two similar terms, "Electricity data for power consumption A (26)"
And "Power use facility data B (27)": "Power use facility data A (26)" is data used by the power user side (2). On the other hand, "Electric power usage facility data B
(27) "is data normally used by the power supplier (1). In this specification, “power use facility data A (2
6) "and" Electric power usage equipment data B (27) "are simply expressed as" Electric power usage equipment data "when it is not necessary to strictly separate them.

"Electric power usage facility data B (27)"
This is data on the electrical physical quantity of the current power consumption of the power usage facility (25), which is in a form that can be processed by a computer. This data is for transactions. The electric physical quantity used for the transaction is usually measured by a measuring device belonging to the electric power supplier (1). This metering device is installed in a power use facility (25) on the power user side (2).

The “received power statement recording unit (28)” is a fee calculation method defined by the contract (this is described in “Contract Data (2)
(1)) (= contract data (11)), calculates the electric power use facility data B (27) and the electronic incentive data transmitted to the electric power user (2), and Create and record detailed billing data (or data essential for determining electricity rates).

The "program setting unit (22)" of the electric power user (2) means that the organization of the electric power user (2) collects the electric power using equipment data A (26) based on the contract data (21). Electronic incentives that are read from a strategic perspective, take into account economic indicators, management policies, etc., determine how to use the incentives contained in the electronic incentive data that is transmitted from the power supplier (1) every day, and transmitted. An outline (theory) for automatically (or manually) controlling the “power use equipment (25)” is set based on the data, and the software is created (software is created). Update the framework (theory) and software as needed according to changes in the situation. (This software is installed in the "calculation / control unit (24)." In the "automatic mode," this software uses the correction data from the "manual operation unit (23)" to provide the "calculation / control unit (24)." In the [manual mode], the control signal for controlling the "power use equipment (25)" which is the output of the control unit can be corrected.
"Electricity using equipment (2
The control signal for direct control of 5)) is output to the “calculation / control section”. )

The "manual operation section (23)" is within the outline defined by the "program setting section (22)" of the electric power user (2), in the case of [automatic mode]; At the discretion of the person in the field, a manual correction operation is performed so as to incorporate it into the control signal output by the "calculation / control section (24)". In the case of [manual mode]; "arithmetic / control unit"
(24) "are all places where a manual operation is performed in which human operation has priority.

The "arithmetic / control unit" (24) means that the program created by the "program setting unit (22)" is installed, and accordingly, in the case of [automatic mode]; the transmitted electronic incentive data and " Power usage facility data A (26) "is calculated, and" power usage facility (25) "
Generate a control signal for controlling If there is a correction input from the "manual operation unit (23)", the generated control signal is corrected by that. [Manual mode]; receives an operation signal from the "manual operation unit (23)"
It outputs a control signal that gives priority to human operation. here;
“Controlling the electric power using facility (25)” means performing the following operation on various load facilities constituting the electric power using facility (25) individually or as a group of load facilities. (Applicable) a. Turn the power on and off. b. Start / stop the machine. c. Adjust the frequency / speed of the machine. d. Lower the set temperature of the heating device. e. Increase the temperature of the cooling device. f. Change driving hours.

The "communication system (3)" is a system for transmitting electronic incentive data online and in real time from the electric power supplier (1) to the electric power user (2). ) And the power user side (2)
Are selected upon agreement. (It is not the object of the present invention to determine the requirements of the communication system (3).) Here, online real-time means that the electronic incentive data is transmitted by any of the following transmission methods. [Transmission method 1]: A method in which electronic incentive data is continuously transmitted from the power supplier (1) to the power user (2). [Transmission method 2]: A method in which electronic incentive data is transmitted from the power supplier side (1) to the power user side (2) periodically or as needed. [Transmission method 3]: A method in which electronic incentive data is transmitted from the power supplier (1) to the power user (2) each time the power user (2) requests.

Although not a requirement of the present invention, since the system is handled by humans, the power supplier (1) displays and records what the incentive data transmitted to the power user (2) was.・ There is a recording unit. The power user (2) also has a display / recording unit that monitors and records the incentive data transmitted from the power supplier (1). (The display and recording units are not shown.)

Effect of the Invention a. A more effective leveling of the supply power than before can be achieved flexibly. In particular, in the “automatic mode”, the leveling of the supplied power is automatically achieved using a computer without human involvement.b.
